Subject: xenbus: do not hold transaction_mutex when returning to userspace

================================================
  [ BUG: lock held when returning to user space! ]
  ------------------------------------------------
  xenstore-list/3522 is leaving the kernel with locks still held!
  1 lock held by xenstore-list/3522:
   #0:  (&xs_state.transaction_mutex){......}, at: [<c026dc6f>] xenbus_dev_request_and_reply+0x8f/0xa0

The canonical fix for this type of issue appears to be to maintain a
count manually rather than using an rwsem so do that here.

Subject: ARM: mach-shmobile: Use shared clock framework

Teach SH-Mobile ARM how to make use of the shared SH clock
framework. This commit is one atomic switch that dumps the
local hackery and instead links in the shared clock framework
code in drivers/sh. A few local functions are kept in clock.c.

Subject: sh-mobile: add support for displays, connected over the MIPI bus

Some SH-mobile SoCs have a MIPI DSI controller, that can be used to connect
MIPI displays to LCDC. This patch adds a platform driver for SH-mobile MIPI DSI
unit. It uses existing hooks in the sh_mobile_lcdcfb.c driver for display
activation and deactivation.

Subject: serial: sh-sci: fix handling of SCIFB sh-mobile ports

SCIFB ports have a slightly different register layout and a different FIFO
size from SCIFA ports, in DMA mode they have to be treated just like SCIFA.

Subject: [ARM] pata_pxa: DMA-capable PATA driver

This patch adds a driver for a harddrive attached to PXA address and data bus.
Unlike pata_platform, this driver allows usage of PXA DMA controller, making the
transmission speed 3x higher.

From 1636f8ac2b08410df4766449f7c86b912443cd99 Mon Sep 17 00:00:00 2001
From: Grant Likely <grant.likely@secretlab.ca>
Date: Fri, 18 Jun 2010 11:09:58 -0600
Subject: sparc/of: Move of_device fields into struct pdev_archdata

This patch moves SPARC architecture specific data members out of
struct of_device and into the pdev_archdata structure.  The reason
for this change is to unify the struct of_device definition amongst
all the architectures.  It also remvoes the .sysdata, .slot, .portid
and .clock_freq properties because they aren't actually used by
anything.

A subsequent patch will replace struct of_device entirely with struct
platform_device and the of_platform support code will share common
routines with the platform bus (but the bus instances themselves can
remain separate).

This patch also adds 'struct resources *resource' and num_resources
to match the fields defined in struct platform_device.  After this
change, 'struct platform_device' can be used as a drop-in replacement
for 'struct of_platform'.

This change is in preparation for merging the of_platform_bus_type
with the platform_bus_type.

From b505ff5e7291cca6379549297e3852ce3622d550 Mon Sep 17 00:00:00 2001
From: Grant Likely <grant.likely@secretlab.ca>
Date: Fri, 18 Jun 2010 11:09:59 -0600
Subject: of: kill struct of_device

Now that the device tree node pointer has been moved out of struct
of_device and into the common struct device, there isn't anything
unique about of_device anymore.  In fact, there isn't much need
for a separate of_bus when all busses have access to OF style
probing.

arch/powerpc and arch/microblaze are moving away from using the of_bus
and using the regular platform bus instead for mmio devices.  This
patch makes of_device the same as platform_device as a stepping stone
in migrating of_platform_drivers over to the platform bus.

Subject: of/irq: Move irq_of_parse_and_map() to common code

Merge common code between PowerPC and Microblaze.  SPARC implements
irq_of_parse_and_map(), but the implementation is different, so it
does not use this code.

Subject: of/irq: merge irq mapping code

Merge common irq mapping code between PowerPC and Microblaze.

This patch merges of_irq_find_parent(), of_irq_map_raw() and
of_irq_map_one().  The functions are dependent on one another, so all
three are merged in a single patch.  Other than cosmetic difference
(ie. DBG() vs. pr_debug()), the implementations are identical.

of_irq_to_resource() is also merged, but in this case the
implementations are different.  This patch drops the microblaze version
and uses the powerpc implementation unchanged.  The microblaze version
essentially open-coded irq_of_parse_and_map() which it does not need
to do.  Therefore the powerpc version is safe to adopt.

Subject: of/address: merge of_address_to_resource()

Merge common code between PowerPC and Microblaze.  This patch also
moves the prototype of pci_address_to_pio() out of pci-bridge.h and
into prom.h because the only user of pci_address_to_pio() is
of_address_to_resource().

From dbbdee94734bf6f1db7af42008a53655e77cab8f Mon Sep 17 00:00:00 2001
From: Grant Likely <grant.likely@secretlab.ca>
Date: Tue, 8 Jun 2010 07:48:10 -0600
Subject: of/address: Merge all of the bus translation code

Microblaze and PowerPC share a large chunk of code for translating
OF device tree data into usable addresses.  Differences between the two
consist of cosmetic differences, and the addition of dma-ranges support
code to powerpc but not microblaze.  This patch moves the powerpc
version into common code and applies many of the cosmetic (non-functional)
changes from the microblaze version.

Certain Apple machines don't use the ranges property correctly, but the
workaround should not be applied on other architectures.  This patch
disables the workaround for non-powerpc architectures.

Subject: of: Modify of_device_get_modalias to be passed struct device

Now that the of_node pointer is part of struct device,
of_device_get_modalias could be used on any struct device
that has the device node pointer set.  This patch changes
of_device_get_modalias to accept a struct device instead
of a struct of_device.

Subject: of/device: Merge of_platform_bus_probe()

Merge common code between PowerPC and microblaze.  This patch merges
the code that scans the tree and registers devices.  The functions
merged are of_platform_bus_probe(), of_platform_bus_create(), and
of_platform_device_create().

This patch also move the of_default_bus_ids[] table out of a Microblaze
header file and makes it non-static.  The device ids table isn't merged
because powerpc and microblaze use different default data.

Subject: of/device: populate platform_device (of_device) resource table on
 allocation

When allocating a platform_device to represent an OF node, also allocate
space for the resource table and populate it with IRQ and reg property
information.  This change is in preparation for merging the
of_platform_bus_type with the platform_bus_type so that existing
platform_driver code can retrieve base addresses and IRQs data.

Background: a previous commit removed struct of_device and made it a
#define alias for platform_device.

Subject: of/gpio: Kill of_gpio_chip and add members directly to gpio_chip

The OF gpio infrastructure is great for describing GPIO connections within
the device tree.  However, using a GPIO binding still requires changes to
the gpio controller just to add an of_gpio structure.  In most cases, the
gpio controller doesn't actually need any special support and the simple
OF gpio mapping function is more than sufficient.  Additional, the current
scheme of using of_gpio_chip requires a convoluted scheme to maintain
1:1 mappings between of_gpio_chip and gpio_chip instances.

If the struct of_gpio_chip data members were moved into struct gpio_chip,
then it would simplify the processing of OF gpio bindings, and it would
make it trivial to use device tree OF connections on existing gpiolib
controller drivers.

This patch eliminates the of_gpio_chip structure and moves the relevant
fields into struct gpio_chip (conditional on CONFIG_OF_GPIO).  This move
simplifies the existing code and prepares for adding automatic device tree
support to existing drivers.

Subject: of/gpio: stop using device_node data pointer to find gpio_chip

Currently the kernel uses the struct device_node.data pointer to resolve
a struct gpio_chip pointer from a device tree node.  However, the .data
member doesn't provide any type checking and there aren't any rules
enforced on what it should be used for.  There's no guarantee that the
data stored in it actually points to an gpio_chip pointer.

Instead of relying on the .data pointer, this patch modifies the code
to add a lookup function which scans through the registered gpio_chips
and returns the gpio_chip that has a pointer to the specified
device_node.

Subject: of/gpio: add default of_xlate function if device has a node pointer

Implement generic OF gpio hooks and thus make device-enabled GPIO chips
(i.e.  the ones that have gpio_chip->dev specified) automatically attach
to the OpenFirmware subsystem.  Which means that now we can handle I2C and
SPI GPIO chips almost* transparently.

* "Almost" because some chips still require platform data, and for these
  chips OF-glue is still needed, though with this change the glue will
  be much smaller.

Subject: of/gpio: fix of_gpio includes

drivers/of/gpio.c is missing includes for of_irq and struct device which
cause build failures on ARM.  This patch adds the correct include files
and removes the unneeded kernel.h include

Subject: of/device: Add OF style matching helper function

Add of_driver_match_device() helper function.  This function can be used
by bus types to determine if a driver works with a device when using OF
style matching.  If CONFIG_OF is unselected, then it is a nop.

From 2ffe8c5f323c3b9749bf7bc2375d909d20bdbb15 Mon Sep 17 00:00:00 2001
From: Grant Likely <grant.likely@secretlab.ca>
Date: Tue, 8 Jun 2010 07:48:19 -0600
Subject: of: refactor of_modalias_node() and remove explicit match table.

This patch tightens up the behaviour of of_modalias_node() to be more
predicatable and to eliminate the explicit of_modalias_tablep[] that
is currently used to override the first entry in the compatible list
of a device.  The override table was needed originally because spi
and i2c drivers had no way to do of-style matching.  Now that all
devices can have an of_node pointer, and all drivers can have an
of_match_table, the explicit override table is no longer needed
because each driver can specify its own OF-style match data.

The mpc8349emitx-mcu driver is modified to explicitly specify the
correct device to bind against.

Subject: of: Put all CONFIG_OF dependencies into a Kconfig menu block

All of the options in drivers/of/Kconfig depend on CONFIG_OF.  Putting
all of them inside a menu block simplifies the dependency statements.
It also creates a logical group for adding user selectable OF options.

This patch also changes (PPC_OF || MICROBLAZE) statements to (!SPARC)
so that those options are available to other architectures (and in
fact the !SPARC conditions should probably be re-evalutated since the
code is more generic now)

This patch also moves the definition of CONFIG_DTC from arch/* to
drivers/of/Kconfig

Subject: drm: sane naming for drm_mm.c

Yeah, I've kinda noticed that fl_entry is the free stack. Still
give it (and the memory node list ml_entry) decent names.

There are already two copies of this logic. And the new scanning
stuff will add some more. So extract it into a small helper
function.

Subject: drm: implement helper functions for scanning lru list

These helper functions can be used to efficiently scan lru list
for eviction. Eviction becomes a three stage process:
1. Scanning through the lru list until a suitable hole has been found.
2. Scan backwards to restore drm_mm consistency and find out which
   objects fall into the hole.
3. Evict the objects that fall into the hole.

These helper functions don't allocate any memory (at the price of
not allowing any other concurrent operations). Hence this can also be
used for ttm (which does lru scanning under a spinlock).

Evicting objects in this fashion should be more fair than the current
approach by i915 (scan the lru for a object large enough to contain
the new object). It's also more efficient than the current approach used
by ttm (uncoditionally evict objects from the lru until there's enough
free space).

More explicit than dpms. Same as the encoder disable function.

Need this to explicity disconnect plls from crtcs for reuse when you
plls:crtcs ratio isn't 1:1.

Subject: hvc_console: use "*_console" nomenclature to avoid modpost warning.

The use of "hvc_con_driver" as the name for a file-static "struct
console" with a ".setup" field pointing to an __init function causes
a modpost warning, since a non-initdata structure points to init code.
Using "hvc_console" as the name triggers the hacky "*_console"
workaround in modpost to silence the warning, and is the same thing
that most of the other console drivers already do.

I made the same change in hvsi.c since I happened to notice it was
likely to suffer from the same problem.

Subject: powerpc: Add i8042 keyboard and mouse irq parsing

Currently the irqs for the i8042, which historically provides keyboard and
mouse (aux) support, is hardwired in the driver rather than parsing the
dts.  This patch modifies the powerpc legacy IO code to attempt to parse
the device tree for this information, failing back to the hardcoded values
if it fails.

Subject: drm/nouveau: Don't clear AGPCMD completely on INIT_RESET.

We just need to clear the SBA and ENABLE bits to reset the AGP
controller: If the AGP bridge was configured to use "fast writes",
clearing the FW bit would break the subsequent MMIO writes and
eventually end with a lockup.

Note that all the BIOSes I've seen do the same as we did (it works for
them because they don't use MMIO), OTOH the blob leaves FW untouched.

Subject: drm/nouveau: tidy connector/encoder creation a little

Create connectors before encoders to avoid having to do another loop across
encoder list whenever we create a new connector.  This allows us to pass
the connector to the encoder creation functions, and avoid using a
create_resources() callback since we can now call it directly.

This can also potentially modify the connector ordering on nv50.  On cards
where the DCB connector and encoder tables are in the same order, things
will be unchanged.  However, there's some cards where the ordering between
the tables differ, and in one case, leads us to naming the connectors
"wrongly".

From 309b8c89c8ddf9dd8e5f253c185d6af1d0358a79 Mon Sep 17 00:00:00 2001
From: Ben Skeggs <bskeggs@redhat.com>
Date: Tue, 29 Jun 2010 16:09:24 +1000
Subject: drm/nouveau: downgrade severity of most init table parser errors

As long as we know the length of the opcode, we're probably better off
trying to parse the remainder of an init table rather than aborting in
the middle of it.

Subject: drm/nv50: DCB quirk for Dell M6300

Uncertain if this is a weirdo configuration, or a BIOS bug.  If it's not
a BIOS bug, we still don't know how to make it work anyway so ignore a
"conflicting" DCB entry to prevent a display hang.

Subject: drm/nv50: supply encoder disable() hook for SOR outputs

Allows us to remove a driver hack that used to be necessary to disable
encoders in certain situations before setting up a mode.  The DRM has
better knowledge of when this is needed than the driver does.

This fixes a number of display switching issues.

Subject: drm/nv04-nv40: Disable connector polling when there're no spare CRTCs
 left.

Load detection needs the connector wired to a CRTC, when there are no
inactive CRTCs left that means we need to cut some other head off for
a while, causing intermittent flickering.

Subject: drm/nouveau: INIT_CONFIGURE_PREINIT/CLK/MEM on newer BIOSes is not an
 error.

No need to spam the logs when they're found, they're equivalent to
INIT_DONE.

Subject: drm/nv50: send evo "update" command after each disconnect

It turns out that the display engine signals an interrupt for disconnects
too.  In order to make it easier to process the display interrupts
correctly, we want to ensure we only get one operation per interrupt
sequence - this is what this commit achieves.

Subject: drm/nv50: rewrite display irq handler

The previous handler basically worked correctly for a full-blown mode
change.  However, it did nothing at all when a partial (encoder only)
reconfiguation was necessary, leading to the display hanging on certain
types of mode switch.

Subject: drm/nouveau: add instmem flush() hook

This removes the previous prepare_access() and finish_access() hooks, and
replaces it with a much simpler flush() hook.

All the chipset-specific code before nv50 has its use removed completely,
as it's not required there at all.

From ec91db269e6a3c7f45b96169ccf5dbd1fde8fce8 Mon Sep 17 00:00:00 2001
From: Ben Skeggs <bskeggs@redhat.com>
Date: Thu, 8 Jul 2010 11:53:19 +1000
Subject: drm/nouveau: remove ability to use external firmware

can hack this in ourselves.

Subject: drm/nouveau: initialise display before enabling interrupts

In some situations it's possible we can receive a spurious hotplug IRQ
before we're ready to handle it, leading to an oops.

Calling the display init before enabling interrupts should clear any
pending IRQs on the GPU and prevent this from happening.

Subject: drm/nouveau: fix pcirom vbios shadow breakage from acpi rom patch

On nv50 it became impossible to attempt a PCI ROM shadow of the VBIOS,
which will break some setups.

This patch also removes the different ordering of shadow methods for
pre-nv50 chipsets.  The reason for the different ordering was paranoia,
but it should hopefully be OK to try shadowing PRAMIN first.

Subject: drivers/of: fix build error when CONFIG_PPC_DCR is set

Commit 94c0931983ee9d1cd96c32d52ac64c17464f0bbd (of:
Merge of_device_alloc() and of_device_make_bus_id()) moved code that
does calls a dcr routine without including the correct header which
causes the following build error on some powerpc configurations:

drivers/of/platform.c: In function 'of_device_make_bus_id':
drivers/of/platform.c:437: error: implicit declaration of function 'of_translate_dcr_address'

This patch adds the appropriate header to drivers/of/platform.c

Subject: of/flattree: Fix crash when device tree absent

This patch fixes the condition where device tree support is compiled
in, but no device tree was proved by firmware.  It makes
of_platform_bus_probe() explicitly check for a NULL device tree
pointer.

Subject: drm: add "auto" dithering method

There's no convenient/reliable way for drivers to both obey the dithering
mode property, and to be able to attempt to provide a good default in all
cases.

This commit adds an "auto" method to the property which drivers can default
to if they wish, whilst still allowing the user to override the choice as
they do now.

Subject: sbus: autoconvert trivial BKL users to private mutex

All these files use the big kernel lock in a trivial
way to serialize their private file operations,
typically resulting from an earlier semi-automatic
pushdown from VFS.

None of these drivers appears to want to lock against
other code, and they all use the BKL as the top-level
lock in their file operations, meaning that there
is no lock-order inversion problem.

Consequently, we can remove the BKL completely,
replacing it with a per-file mutex in every case.
Using a scripted approach means we can avoid
typos.

file=$1
name=$2
if grep -q lock_kernel ${file} ; then
    if grep -q 'include.*linux.mutex.h' ${file} ; then
            sed -i '/include.*<linux\/smp_lock.h>/d' ${file}
    else
            sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file}
    fi
    sed -i ${file} \
        -e "/^#include.*linux.mutex.h/,$ {
                1,/^\(static\|int\|long\)/ {
                     /^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex);

} }"  \
    -e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \
    -e '/[      ]*cycle_kernel_lock();/d'
else
    sed -i -e '/include.*\<smp_lock.h\>/d' ${file}  \
                -e '/cycle_kernel_lock()/d'

Subject: x86: early PV on HVM features initialization.

Initialize basic pv on hvm features adding a new Xen HVM specific
hypervisor_x86 structure.

Don't try to initialize xen-kbdfront and xen-fbfront when running on HVM
because the backends are not available.

Subject: x86/xen: event channels delivery on HVM.

Set the callback to receive evtchns from Xen, using the
callback vector delivery mechanism.

The traditional way for receiving event channel notifications from Xen
is via the interrupts from the platform PCI device.
The callback vector is a newer alternative that allow us to receive
notifications on any vcpu and doesn't need any PCI support: we allocate
a vector exclusively to receive events, in the vector handler we don't
need to interact with the vlapic, therefore we avoid a VMEXIT.

From 183d03cc4ff39e0f0d952c09aa96d0abfd6e0c3c Mon Sep 17 00:00:00 2001
From: Stefano Stabellini <stefano.stabellini@eu.citrix.com>

Subject: xen: Xen PCI platform device driver.

Add the xen pci platform device driver that is responsible
for initializing the grant table and xenbus in PV on HVM mode.
Few changes to xenbus and grant table are necessary to allow the delayed
initialization in HVM mode.
Grant table needs few additional modifications to work in HVM mode.

The Xen PCI platform device raises an irq every time an event has been
delivered to us. However these interrupts are only delivered to vcpu 0.
The Xen PCI platform interrupt handler calls xen_hvm_evtchn_do_upcall
that is a little wrapper around __xen_evtchn_do_upcall, the traditional
Xen upcall handler, the very same used with traditional PV guests.

When running on HVM the event channel upcall is never called while in
progress because it is a normal Linux irq handler (and we cannot switch
the irq chip wholesale to the Xen PV ones as we are running QEMU and
might have passed in PCI devices), therefore we cannot be sure that
evtchn_upcall_pending is 0 when returning.
For this reason if evtchn_upcall_pending is set by Xen we need to loop
again on the event channels set pending otherwise we might loose some
event channel deliveries.

Subject: xen: Add suspend/resume support for PV on HVM guests.

Suspend/resume requires few different things on HVM: the suspend
hypercall is different; we don't need to save/restore memory related
settings; except the shared info page and the callback mechanism.

Subject: xen: Fix find_unbound_irq in presence of ioapic irqs.

Don't break the assumption that the first 16 irqs are ISA irqs;
make sure that the irq is actually free before using it.

Use dynamic_irq_init_keep_chip_data instead of
dynamic_irq_init so that chip_data is not NULL (a NULL chip_data breaks
setup_vector_irq).

Date: Tue, 8 Jun 2010 07:48:21 -0600
Subject: of: Merge of_platform_bus_type with platform_bus_type

of_platform_bus was being used in the same manner as the platform_bus.
The only difference being that of_platform_bus devices are generated
from data in the device tree, and platform_bus devices are usually
statically allocated in platform code.  Having them separate causes
the problem of device drivers having to be registered twice if it
was possible for the same device to appear on either bus.

This patch removes of_platform_bus_type and registers all of_platform
bus devices and drivers on the platform bus instead.  A previous patch
made the of_device structure an alias for the platform_device structure,
and a shim is used to adapt of_platform_drivers to the platform bus.

After all of of_platform_bus drivers are converted to be normal platform
drivers, the shim code can be removed.

Subject: of/platform: remove all of_bus_type and of_platform_bus_type
 references

Both of_bus_type and of_platform_bus_type are just #define aliases
for the platform bus.  This patch removes all references to them and
switches to the of_register_platform_driver()/of_unregister_platform_driver()
API for registering.

Subsequent patches will convert each user of of_register_platform_driver()
into plain platform_drivers without the of_platform_driver shim.  At which
point the of_register_platform_driver()/of_unregister_platform_driver()
functions can be removed.

Subject: of/device: Protect against binding of_platform_drivers to non-OF
 devices

There is an unlikely chance of this situation is occurring, but it is
easy to protect against.  If a matching entry cannot be found in the
of_match_table, then don't bind the driver.

Subject: of/device: Replace of_device with platform_device in includes and
 core code

of_device is currently just an #define alias to platform_device until it
gets removed entirely.  This patch removes references to it from the
include directories and the core drivers/of code.

There's no need for this function to be architecture specific and all four
architectures defining it had the same definition.  The function has been
moved to drivers/of/platform.c.

Subject: of: remove of_default_bus_ids

This list used was by only two platforms with all other platforms defining an
own list of valid bus id's to pass to of_platform_bus_probe.  This patch:

i)   copies the default list to the two platforms that depended on it (powerpc)
ii)  remove the usage of of_default_bus_ids in of_platform_bus_probe
iii) removes the definition of the list from all architectures that defined it

Passing a NULL 'matches' parameter to of_platform_bus_probe is still valid; the
function returns no error in that case as the NULL value is equivalent to an
empty list.

[grant.likely@secretlab.ca: added __initdata annotations, warn on and return error on missing match table, and fix whitespace errors]

Subject: of/flattree: fix of_flat_dt_is_compatible() to match the full
 compatible string

With the current string comparison, a device tree compatible of "foo-bar"
would match as compatible with a driver looking for "foo".  This patch
fixes the function to use the of_compat_cmp() macro so that it does the
right thing on all platforms (If sparc ever uses this code, it will still
want the strncasecmp() behaviour).

Subject: of: Fix phandle endian issues

The flat tree code wasn't fixing the endianness on phandle values when
unflattening the tree, and the code in drivers/of wasn't always doing a
be32_to_cpu before trying to dereference the phandle values.  This patch
fixes them.

Subject: powerpc/5200: improve uart baud rate calculation (reach high baud
 rates, better accuracy)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On the MPC5200B, make very high baud rates (e.g. 3 MBaud) accessible and
achieve a higher precision for high baud rates in general.  This is done by
selecting the appropriate prescaler (/4 or /32).  As to keep the code clean,
the getuartclk method has been dropped, and all calculations are done in a
new set_baudrate method.

Notes: only "fsl,mpc5200b-psc-uart" compatible devices benefit from these
improvements.

Tested on a custom 5200B based board, from 110 baud up to 3 MBaud, and with
both "fsl,mpc5200b-psc-uart" and "fsl,mpc5200-psc-uart" devices.
Also tested on the mpc5121ads board.

Subject: drm/nouveau: remove quirk to fabricate DVI-A output on DCB 1.5 boards

There's a report of this quirk breaking modesetting on at least one board.
After discussion with Francisco Jerez, we've decided to remove it:

<darktama> it's not worth limiting the quirk to just where we know it can
           work?  i'm happy either way really :)
<curro> hmm, don't think so, most if not all DCB15 cards have just one DAC
<curro> and with that quirk there's no way to tell if the load comes from
        the VGA or DVI port

Subject: drm/nv50: fix regression that break LVDS in some places

match the correct output script.  However, we never fill in this field
for LVDS so we can never match a script at all.

From 67eda20e6b7a757ed45f6b5a8a4d30c2a0d47c7a Mon Sep 17 00:00:00 2001
From: Francisco Jerez <currojerez@riseup.net>
Date: Tue, 13 Jul 2010 15:59:50 +0200
Subject: drm/nv04-nv3x: Implement init-compute-mem.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Init-compute-mem was the last piece missing for nv0x-nv3x card
cold-booting. This implementation is somewhat lacking but it's been
reported to work on most chipsets it was tested in. Let me know if it
breaks suspend to RAM for you.

-	 * This opcode is meant to set NV_PFB_CFG0 (0x100200) appropriately so
-	 * that the hardware can correctly calculate how much VRAM it has
-	 * (and subsequently report that value in NV_PFB_CSTATUS (0x10020C))

+	 * appropriately so that we can correctly calculate how much VRAM it
+	 * has (on nv10 and better chipsets the amount of installed VRAM is
+	 * subsequently reported in NV_PFB_CSTATUS (0x10020C)).
 	 *
-	 * The implementation of this opcode in general consists of two parts:
-	 * 1) determination of the memory bus width
-	 * 2) determination of how many of the card's RAM pads have ICs attached
+	 * The implementation of this opcode in general consists of several
+	 * parts:
 	 *
-	 * 1) is done by a cunning combination of writes to offsets 0x1c and
-	 * 0x3c in the framebuffer, and seeing whether the written values are
-	 * read back correctly. This then affects bits 4-7 of NV_PFB_CFG0
+	 * 1) Determination of memory type and density. Only necessary for
+	 *    really old chipsets, the memory type reported by the strap bits
+	 *    (0x101000) is assumed to be accurate on nv05 and newer.
 	 *
-	 * 2) is done by a cunning combination of writes to an offset slightly
-	 * less than the maximum memory reported by NV_PFB_CSTATUS, then seeing
-	 * if the test pattern can be read back. This then affects bits 12-15 of
-	 * NV_PFB_CFG0
+	 * 2) Determination of the memory bus width. Usually done by a cunning
+	 *    combination of writes to offsets 0x1c and 0x3c in the fb, and
+	 *    seeing whether the written values are read back correctly.
 	 *
-	 * In this context a "cunning combination" may include multiple reads
-	 * and writes to varying locations, often alternating the test pattern
-	 * and 0, doubtless to make sure buffers are filled, residual charges
-	 * on tracks are removed etc.
+	 *    Only necessary on nv0x-nv1x and nv34, on the other cards we can
+	 *    trust the straps.
 	 *
-	 * Unfortunately, the "cunning combination"s mentioned above, and the
-	 * changes to the bits in NV_PFB_CFG0 differ with nearly every bios
-	 * trace I have.
+	 * 3) Determination of how many of the card's RAM pads have ICs
+	 *    attached, usually done by a cunning combination of writes to an
+	 *    offset slightly less than the maximum memory reported by
+	 *    NV_PFB_CSTATUS, then seeing if the test pattern can be read back.
 	 *
-	 * Therefore, we cheat and assume the value of NV_PFB_CFG0 with which
-	 * we started was correct, and use that instead
+	 * This appears to be a NOP on IGPs and NV4x or newer chipsets, both io
+	 * logs of the VBIOS and kmmio traces of the binary driver POSTing the

Subject: drm/nouveau: Reset AGP before running the init scripts.

BIOS scripts usually make an attempt to reset the AGP controller,
however on some nv4x cards doing it properly involves switching FW off
and on: if we do that without updating the AGP bridge settings
accordingly (e.g. with the corresponding calls to agp_enable()) we
will be locking ourselves out of the card MMIO space. Do it from
nouveau_mem_reset_agp() before the init scripts are executed.

Subject: drm/nouveau: Put back the old 2-messages I2C slave test.

I was hoping we could detect I2C devices at a given address without
actually writing data into them, but apparently some DDC slaves get
confused with 0-bytes transactions. Put the good old test back.

Subject: Remove REDWOOD_[456] config options and conditional code

The config options for REDWOOD_[456] were commented out in the powerpc
Kconfig. The ifdefs referencing this options therefore are dead and all
references to this can be removed (Also dependencies in other KConfig
files).

Subject: x86: Unplug emulated disks and nics.

Add a xen_emul_unplug command line option to the kernel to unplug
xen emulated disks and nics.

Set the default value of xen_emul_unplug depending on whether or
not the Xen PV frontends and the Xen platform PCI driver have
been compiled for this kernel (modules or built-in are both OK).

The user can specify xen_emul_unplug=ignore to enable PV drivers on HVM
even if the host platform doesn't support unplug.

Subject: blkfront: do not create a PV cdrom device if xen_hvm_guest

It is not possible to unplug emulated cdrom devices, and PV cdroms don't
handle media insert, eject and stream, so we are better off disabling PV
cdroms when running as a Xen HVM guest.

Subject: of/device: Make of_device_make_bus_id() usable by other code.

The AMBA bus should also use of_device_make_bus_id() when populating device
out of device tree data.  This patch makes the function non-static, and
adds a suitable prototype in of_device.h

Subject: of/spi: call of_register_spi_devices() from spi core code

Move of_register_spi_devices() call from drivers to
spi_register_master(). Also change the function to use
the struct device_node pointer from master spi device
instead of passing it as function argument.

Subject: of/address: Clean up function declarations

This patch moves the declaration of of_get_address(), of_get_pci_address(),
and of_pci_address_to_resource() out of arch code and into the common
linux/of_address header file.

This patch also fixes some of the asm/prom.h ordering issues.  It still
includes some header files that it ideally shouldn't be, but at least the
ordering is consistent now so that of_* overrides work.

Subject: of/platform: Register of_platform_drivers with an "of:" prefix

Currently there are some drivers in tree which register both a
platform_driver and an of_platform_driver with the same name.  This is
a temporary situation until all the relevant of_platform_drivers are
converted to be normal platform_drivers.  Until then, this patch gives
all the of_platform_drivers an "of:" prefix to protect against bogus
matches and namespace conflicts.

Subject: powerpc/5121: fsl-diu-fb: fix issue with re-enabling DIU area
 descriptor

On MPC5121e Rev 2.0 re-configuring the DIU area descriptor
by writing new descriptor address doesn't always work.
As a result, DIU continues to display using old area descriptor
even if the new one has been written to the descriptor register of
the plane.

Add the code from Freescale MPC5121EADS BSP for writing descriptor
addresses properly. This fixes the problem for Rev 2.0 silicon.

Some DIU structures will be used in platform code in
subsequent MPC5121 DIU patch, so we move this header
to be able to include it elsewhere.

From 4b5006ec7bb73cd9d4c8a723d484b4c87fad4123 Mon Sep 17 00:00:00 2001
From: Anatolij Gustschin <agust@denx.de>
Date: Fri, 23 Jul 2010 04:00:37 +0000
Subject: powerpc/5121: shared DIU framebuffer support

MPC5121 DIU configuration/setup as initialized by the boot
loader currently will get lost while booting Linux. As a
result displaying the boot splash is not possible through
the boot process.

To prevent this we reserve configured DIU frame buffer
address range while booting and preserve AOI descriptor
and gamma table so that DIU continues displaying through
the whole boot process. On first open from user space
DIU frame buffer driver releases the reserved frame
buffer area and continues to operate as usual.

Subject: powerpc/fsl-diu-fb: Support setting display mode using EDID

Adds support for encoding display mode information
in the device tree using verbatim EDID block.

If the EDID entry in the DIU node is present, the
driver will build mode database using EDID data
and allow setting the display modes from this database.
Otherwise display mode will be set using mode
entries from driver's internal database as usual.

This patch also updates device tree bindings.

Subject: powerpc/5200/i2c: improve i2c bus error recovery
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch improves the recovery of the MPC's I2C bus from errors like bus
hangs resulting in timeouts:
1. make the bus timeout configurable, as it depends on the bus clock and
    the attached slave chip(s); default is still 1 second;
2. detect any of the cases indicated by the CF, BB and RXAK MSR flags if a
    timeout occurs, and add a missing (required) MAL reset;
3. use a more reliable method to fixup the bus if a hang has been detected.
    The sequence is sent 9 times which seems to be necessary if a slave
    "misses" more than one clock cycle.  For 400 kHz bus speed, the fixup is
    also ~70us (81us vs. 150us) faster.

Tested on a custom Lite5200b derived board, with a Dallas RTC, AD sensors
and NXP IO expander chips attached to the i2c.

Changes vs. v1:
- use improved bus fixup sequence for all chips (not only the 5200)
- calculate real clock from defaults if no clock is given in the device tree
- better description (I hope) of the changes.

I didn't split the changes in this file into three parts as recommended by
Grant, as they actually belong together (i.e. they address one single
problem, just in three places of one single source file).

- Use rdev->family rather than rdev->flags & RADEON_FAMILY_MASK for kms
- replace rn50 check using ids with ASIC_IS_RN50 convenience macro

Subject: drm/radeon/kms: add support for internal thermal sensors (v3)

rv6xx/rv7xx/evergreen families supported; older asics did
not have an internal thermal sensor.

Note, not all oems use the internal thermal sensor, so it's
only exposed in cases where it is used.

Note also, that most laptops use an oem specific ACPI solution for
GPU thermal information rather than using the internal thermal
sensor directly.

v2: export millidegrees celsius, use hwmon device properly.
v3: fix Kconfig

Subject: drm/radeon/kms: fix CS alignment checking for tiling (v2)

Covers depth, cb, and textures. Hopefully I got this right.

v2: - fix bugs:
      https://bugs.freedesktop.org/show_bug.cgi?id=28327
      https://bugs.freedesktop.org/show_bug.cgi?id=28381
    - use ALIGNED(), IS_ALIGNED() macros

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is needed to enable audio support on devices using polling. In case user
decides to disable audio (module parameter) we still will try to use timer in
r600_audio_enable_polling. This would lead to BUG in kernel/timer.c.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

We will need method of selecting encoder that should receive HDMI block. For
now we assign HDMI block to first enabled encoder. Hopefully there are not many
RS6x0 chips with two digital encoders.

[airlied: add RS740 checks as per Alex suggestion.]

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is required for the NB_MISC regs on rs780/rs880 which
means HDMI/DVI/DP ports using PCIEPHY won't work without
it. It might also help with s/r (asic init) issues on other
atombios cards.

Fixes:

and similar issues reported by Alberto Milone.

Subject: drm/radeon: fall back to GTT if bo creation/validation in VRAM fails.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This fixes a problem where on low VRAM cards we'd run out of space for validation.

[airlied: Tested on my M7, Thinkpad T42, compiz works with no problems.]

Subject: drm/radeon/kms: check/restore sanity before doing anything else with
 GPU.

On systems using kexec, the new kernel is booted straight from the old kernel, without any warning to the graphics driver. So the GPU is basically left as-is in a running state, however the CPU side is completly reset.

Without stating the saneness of anyone using kexec on live systems, we should at least try not to crash the GPU. This patch resets 3 registers to 0 that could cause bad things to happen to the running system.

This allows kexec to work on a Power6/RN50 system.

Subject: drm: radeon: fix sign bug

The "error" variable is unsigned so it's never less than zero.  I
changed it to check if (freq < current_freq) directly.

"best_error" is also unsigned so "best_error - 100" could be a large
number instead of a negative.  Since "error" is unsigned it is never
less than a negative and so the cases where "best_error" is less than or
equal to 100 are false.

Subject: drm/radeon/kms: remove rs4xx gart limit

We used to limit the rs4xx gart aperture to 32 MB, but I suspect
that was due to not meeting the alignment requirements of the
aperture.  This patch should only be applied after:
"drm/radeon/kms: fix gtt MC base alignment on rs4xx/rs690/rs740 asics"
has been applied.

This patch should probably soak for a bit in d-r-t.

Subject: drm/nouveau: set TASK_(UN)INTERRUPTIBLE before schedule_timeout()

set_current_state() is called only once before the first iteration.
After return from schedule_timeout() current state is TASK_RUNNING. If
we are going to wait again, set_current_state() must be called.

Subject: drm: Free the idr layers before calling idr_destroy()

/* A typical clean-up sequence for objects stored in an idr tree, will
 * use idr_for_each() to free all objects, if necessary, then
 * idr_remove_all() to remove all ids, and idr_destroy() to free
 * up the cached idr_layers.
 */

We were missing the vital idr_rmove_all() step and so were leaking
the used layers for every dri client:

Subject: drm: Free devname along with master->unique

The device name is tightly coupled and created at the same time as the
master->unique address, so we need to free it with the master. Currently
we overwrite it each time we create a new master:

unreferenced object 0xe32c54b0 (size 32):
  comm "Xorg", pid 1455, jiffies 4294721798 (age 3196.879s)

    3a 30 32 2e 30 00 6b 6b 6b 6b 6b 6b 6b 6b 6b a5  :02.0.kkkkkkkkk.

From d9fdaafbe912a34ef06ed569c6606fe2811f325b Mon Sep 17 00:00:00 2001
From: Dave Airlie <airlied@redhat.com>
Date: Mon, 2 Aug 2010 10:42:55 +1000
Subject: drm/radeon/kms: move a bunch of modesetting debug to correct debug
 usage.

This migrates a bunch of DRM_DEBUG->DRM_DEBUG_KMS so we can get more modesetting related info without all the other ioctl handling easily.

Also the PM code moves to DRM_DEBUG_DRIVER mostly.

From ab9e1f5966591dc3e811418e96ba04f284c52458 Mon Sep 17 00:00:00 2001
From: Dave Airlie <airlied@redhat.com>
Date: Tue, 13 Jul 2010 11:11:11 +1000
Subject: drm/radeon: add basic zmask/hiz support (v4)

This interface allows userspace to request hyperz support, it probably
needs more locking, and really reporting that you can have hyperz is racy
since someone else might get it before you do.

v2: modify so we pass 0 valued packets to let DDX/r300c keep working.
also fixed incorrect 0x4f1c reference.

v3: fixup zb_bw_cntl so older drivers keep working

v4: add locking, fixup SC_HYPERZ_EN - patch stream to disable hiz

Signed-off-by: Dave Airlie <airlied@redhat.com>

Subject: gpu/drm/i915: Add a blacklist to omit modeset on LID open
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

On some machines (currently only the Toshiba Tecra A11 is known), the GPU
locks up when modeset is forced on LID open. This patch adds a new DMI
blacklist and omits modesetting for all matches.

Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15550

Oops, when merging the extra details following an OOM, I missed that
driver_private is now NULL and the correct way to convert from the
drm_gem_object into the drm_i915_gem_object is to use to_intel_bo().

When "onboard video memory" is set do "disabled" in BIOS on Asus P4P800-VM

Subject: drm/i915: Add the support of eDP on DP-D for Ibex/CPT

This one adds support for eDP that connected on PCH DP-D port
instead of CPU DP-A port, and only DP-D port could be used for eDP.

Subject: drm/i915: Fix watermark calculation in self-refresh mode

For self-refresh mode WM calculation's "line time" should use
mode's htotal instead of hdisplay. "surface width" is the hdisplay
for display plane and 64 for cursor plane.

Subject: drm/i915: Fix fifo size for self-refresh watermark on 965G

The total self-refresh fifo entry size for display plane is 512
instead of 128 for 965G. Also fix WM value mask for 965G.

About 1.0W power can be saved on one T61 laptop after the self-refresh
watermark is configured correctly.

Subject: drm/i915: Calculate cursor watermark under non-SR state for Ironlake

The hardware team suggest that the "large buffer" method should be
used to calculate the cursor watermark under non-SR state as well,
which is to avoid the flicker when FBC is enabled on Ironlake.

Subject: drm/i915: fix FDI frequency check

Since mode->clock is in kHz we should be checking against 2700000
instead of just 27000.  This patch gets my x201s working again (well
working as well as it ever was anyway).

When looking for this I also noticed we set link_bw to 270000, but the
calculation is different.  Does it also need to use kHz or we using
10kHz internally?

We generally issue an error message at the point of failure, and so this
warning with a fairly pointless stacktrace is superfluous and ugly.
Needless to say, the common trigger for this WARN happens to be EIO
where this is pure noise.

Subject: drm/i915/pch: Cosmetic fix to FDI link training

Unmask the bits for link training reporting before starting link
training.  If stage 1 training finished before we unmask them, then we'd
spin around in a loop a few times until smashing on through.  Which is
harmless, since training _did_ succeed, it just looks ugly in dmesg.

Subject: drm/i915: Use 128k alignment for untiled display surface on i965 (v2)

The original i965, including the revised G35 and Q35, requires an
alignment of 128K for the display surface with linear memory, so
increase the requirement from 64k for these chipsets. For the later
chipsets in the i965 family, only a 4k alignment is required. (So
long as we do not start performing asynchronous flips.)

Note the impact of this should be slight as on i965 we should be using a
tiled frontbuffer for anything up to a 4096x4096 display.

v2: compilation fixes and note that the docs do not exclude the G35 from
the extra alignment.

Subject: drm/i915: Include any alternate names by which the device is known.

When trying to keep track of features between the kernel, the 2D driver,

Subject: agp/intel: Destroy the scatterlist on allocation failure

A side-effect of being able to use custom page allocations with the
sg_table is that it cannot reap the partially constructed scatterlist if
fails to allocate a page. So we need to call sg_free_table() ourselves
if sg_alloc_table() fails.

Subject: drm/i915: apply DP bandwidth workaround for PCH eDP as well

Fixes https://bugs.freedesktop.org/show_bug.cgi?id=29141 though the
workaround itself is still a bit of a mystery.

Subject: drm/i915: Refactor panel fitting on the LVDS. (v2)

Move the common routines into separate functions to not only increase
readability, but also throwaway surplus code.

In doing so, we review the calculation of the aspect preserving scaling
and avoid the use of fixed-point until we need to calculate the accurate
scale factor.

v2: Improve comments as suggested by Jesse.

Subject: drm/i915: Check overlay stride errata for i830 and i845

Apparently i830 and i845 cannot handle any stride that is not a multiple
of 256, unlike their brethren which do support 64 byte aligned strides.

Even though "we have enough padding that it should be ok", round up the
watermark entries to the next unit to be on the safe side...

v2: Use the DIV_ROUND_UP macro
v3: Spotted a few more missing round-ups.

Subject: drm/i915: Repeat unbinding during free if interrupted (v6)

If during the freeing of an object the unbind is interrupted by a system
call, which is quite possible if we have outstanding GPU writes that
must be flushed, the unbind is silently aborted. This still leaves the
AGP region and backing pages allocated, and perhaps more importantly,
the object remains upon the various lists exposing us to memory
corruption.

I think this is the cause behind the use-after-free, such as

  Bug 15664 - Graphics hang and kernel backtrace when starting Azureus
              with Compiz enabled
  https://bugzilla.kernel.org/show_bug.cgi?id=15664

v2: Daniel Vetter reminded me that kernel space programming is never easy.
We cannot simply spin to clear the pending signal and so must deferred
the freeing of the object until later.
v3: Run from the top level retire requests.
v4: Tested with P(return -ERESTARTSYS)=.5 from i915_gem_do_wait_request()
v5: Rebase against Eric's for-linus tree.
v6: Refactor, split and add a comment about avoiding unbounded recursion.

Subject: drm/i915: Attempt to uncouple object after catastrophic failure in
 unbind

If we fail to flush outstanding GPU writes but return the memory to the
system, we risk corrupting memory should the GPU recovery and complete
those writes. On the other hand, if we bail early and free the object
then we have a definite use-after-free and real memory corruption.
Choose the lesser of two evils, since in order to recover from the hung
GPU we need to completely reset it, those pending writes should
never happen.

Subject: drm/i915: Unreference object not handle on creation

When creating an object, we create the handle by which it is known to
the process and which own the reference to the object. That reference to
the new handle is what we want to transfer to the process, not the lost
reference to the object; so free the local object reference *not* the
process's handle reference.

This brings i915_gem_object_create_ioctl() into line with
drm_gem_open_ioctl()

Subject: drm/i915: Unset cursor if out-of-bounds upon mode change (v4)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The docs warn that to position the cursor such that no part of it is
visible on the pipe is an undefined operation. Avoid such circumstances
upon changing the mode, or at any other time, by unsetting the cursor if
it moves out of bounds.

"For normal high resolution display modes, the cursor must have at least a
single pixel positioned over the active screen.” (p143, p148 of the hardware
registers docs).

Fixes:

  Bug 24748 - [965G] Graphics crashes when resolution is changed with KMS
              enabled
  https://bugs.freedesktop.org/show_bug.cgi?id=24748

v2: Only update the cursor registers if they change.
v3: Fix the unsigned comparision of x,y against width,height.
v4: Always set CUR.BASE or else the cursor may become corrupt.

Subject: drm/agp/i915: trim stolen space to 32M

Some BIOSes will claim a large chunk of stolen space.  Unless we
reclaim it, our aperture for remapping buffer objects will be
constrained.  So clamp the stolen space to 32M and ignore the rest.

Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15469 among others.

Adding the ignored stolen memory back into the general pool using the
memory hotplug code is left as an exercise for the reader.

Subject: drm/radeon/kms: make sure rio_mem is valid before unmapping it

If we were not able to map the io bar in device init, don't attempt
to unmap it in device fini.  All radeons should have a io bar, so
I doubt this would ever trigger, but just to be on the safe side...

Subject: drm: move ttm global code to core drm

I wrote this for the prime sharing work, but I also noticed other external
non-upstream drivers from a large company carrying a similiar patch, so I
may as well ship it in master.

From e06b14ee91a2ddefc9a67443a6cd8ee0fa800115 Mon Sep 17 00:00:00 2001
From: Alex Deucher <alexdeucher@gmail.com>
Date: Mon, 2 Aug 2010 12:13:46 -0400
Subject: drm/radeon/kms: handle the case of no active displays properly in the
 bandwidth code

Logic was:
if (mode0 && mode1)
else if (mode0)
else

Should be:
if (mode0 && mode1)
else if (mode0)
else if (mode1)

Otherwise we may end up calculating the priority regs with
unitialized values.

Fixes:

Subject: drm/radeon/kms: fix calculation of h/v scaling factors

Prior to this patch the code was dividing the src_v by the dst_h
and vice versa, rather than src_v/dst_v and src_h/dst_h.

This could lead to problems in the calculation of the display
watermarks.

Subject: drm/radeon/kms: enable underscan option for digital connectors

This connector attribute allows you to enable or disable underscan
on a digital output to compensate for panels that automatically
overscan (e.g., many HDMI TVs).  Valid values for the attribute are:

off - forces underscan off
on - forces underscan on
auto - enables underscan if an HDMI TV is connected, off otherwise

default value is auto.

sh_mobile_lcdc_setup_clocks() can perform IO, therefore it has to be called
after ioremap(). Also check return code of ioremap() and use resource_size()
instead of open-coding it.

From 6011bdeaa6089d49c02de69f05980da7bad314ab Mon Sep 17 00:00:00 2001
From: Guennadi Liakhovetski <g.liakhovetski@gmx.de>
Date: Wed, 21 Jul 2010 10:13:21 +0000
Subject: fbdev: sh-mobile: HDMI support for SH-Mobile SoCs

Some SH-Mobile SoCs have an HDMI controller and a PHY, attached to one of their
LCDC interfaces. This patch adds a preliminary static support for such
controllers, this means, that only the 720p mode is handled ATM. Support for
more modes and a dynamic switching between them will be added by a follow up
patch.

Subject: pvops: do not notify callers from register_xenstore_notifier

Currently register_xenstore_notifier notifies the caller during the
registration itself if xenstore is believed to be ready. This behaviour
causes problems to PV on HVM guests, in which case callers should be
notified by xenbus_probe only after the platform pci driver is loaded.
We already make sure xenbus_probe is called at the right time, calling
it either from device_initcall (PV case) or from the platform pci
driver initialization (HVM case) so we don't need this additional
notification.

Subject: drm: Cleanup after failing to create master->unique and dev->name

v2: Userspace (notably xf86-video-{intel,ati}) became confused when
drmSetInterfaceVersion() started returning -EBUSY as they used a second
call (the first done in drmOpen()) to check their master credentials.
Since userspace wants to be able to repeatedly call
drmSetInterfaceVersion() allow them to do so.

v3: Rebase to drm-core-next.

Subject: drm/kms: Simplify setup of the initial I2C encoder config.

In most use cases the driver will be using the same static config all
the time: interpreting i2c_board_info::platform_data as the default
config we can can save the GPU driver a redundant set_config() call.

Subject: drm: kill BKL from common code

This restricts the use of the big kernel lock to the i830 and i810
device drivers. The three remaining users in common code (open, ioctl
and release) get converted to a new mutex, the drm_global_mutex,
making the locking stricter than the big kernel lock.

This may have a performance impact, but only in those cases that
currently don't use DRM_UNLOCKED flag in the ioctl list and would
benefit from that anyway.

The reason why i810 and i830 cannot use drm_global_mutex in their
mmap functions is a lock-order inversion problem between the current
use of the BKL and mmap_sem in these drivers. Since the BKL has
release-on-sleep semantics, it's harmless but it would cause trouble
if we replace the BKL with a mutex.

Instead, these drivers get their own ioctl wrappers that take the
BKL around every ioctl call and then set their own handlers as
DRM_UNLOCKED.

Subject: virtio_blk: support barriers without FLUSH feature

If we want to support barriers with the cache=writethrough mode in qemu
we need to tell the block layer that we only need queue drains to
implement a barrier.  Follow the model set by SCSI and IDE and assume
that there is no volatile write cache if the host doesn't advertize it.
While this might imply working barriers on old qemu versions or other
hypervisors that actually have a volatile write cache this is only a
cosmetic issue - these hypervisors don't guarantee any data integrity
with or without this patch, but with the patch we at least provide
data ordering.

Subject: virtio_blk: Add 'serial' attribute to virtio-blk devices (v2)

Create a new attribute for virtio-blk devices that will fetch the serial number
of the block device.  This attribute can be used by udev to create disk/by-id
symlinks for devices that don't have a UUID (filesystem) associated with them.

ATA_IDENTIFY strings are special in that they can be up to 20 chars long
and aren't required to be nul-terminated.  The buffer is also zero-padded
meaning that if the serial is 19 chars or less that we get a nul-terminated
string.  When copying this value into a string buffer, we must be careful to
copy up to the nul (if it present) and only 20 if it is longer and not to
attempt to nul terminate; this isn't needed.

Changes since v1:
- Added BUILD_BUG_ON() for PAGE_SIZE check
- Removed min() since BUILD_BUG_ON() handles the check
- Replaced serial_sysfs() by copying id directly to buffer

Subject: virtio_blk: Remove VBID ioctl

With the availablility of a sysfs device attribute for examining disk serial
numbers the ioctl is no longer needed.  The user-space changes for this aren't
upstream yet so we don't have any users to worry about.

Subject: ARM: SAMSUNG: serial: Add FRACVAL support for newer UART

Add support for the FRACVAL register on the newer UART blocks which provides
the same function as UDIVSLOT register but the FRACVAL is easier to implement.
To support UDIVSLOT register, UDIVSLOT table search is necessary though
supporting FRACVAL only needs the index value of UDIVSLOT table.

This patch adds UART serial port support for S5PV310.
In the case of that serial device has just one clock source, driver can not
control clock source. So add check function in get_clksrc and set_clksrc.

Subject: rtc: rtc-s3c: Updates driver for S3C64XX and newer SoCs

This Patch does followings.
1) Enables support for alarm and time tick pending register
   for periodic interrupt generation.
2) Changes writeb to writew beacuse the macro S3C64XX_RTCCON_TICEN
   (Tick Timer Enable) is 9th bit of register.
3) Changes writeb to writel as max_user_freq used in s3c64xx is 32768 and
   requires 15 bits to update the Tick Count Register.

From 42a4f17dc356689075263d7c2bd68456676fa62e Mon Sep 17 00:00:00 2001
From: Manuel Lauss <manuel.lauss@googlemail.com>

Subject: MIPS: Alchemy: remove SOC_AU1X00 in favor of MIPS_ALCHEMY

Remove the CONFIG_SOC_AU1X00 Kconfig symbol since its job can also be done
by MACH_ALCHEMY, now renamed to MIPS_ALCHEMY.

Subject: SERIAL: 8250: Remove SERIAL_8250_AU1X00

Remove the SERIAL_8250_AU1X00 config symbol.  Instead, use the MIPS_ALCHEMY
one which is always defined when building an Au1x00-based platform.

Signed-off-by: Manuel Lauss <manuel.lauss@googlemail.com>
To: Linux-MIPS <linux-mips@linux-mips.org>
Cc: Linux-serial <linux-serial@vger.kernel.org>
Patchwork: https://patchwork.linux-mips.org/patch/1461/
Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

This one depends on a previous patch (which removes SOC_AU1X00 and changes
MACH_ALCHEMY) to apply cleanly (and then actually work), so I'd love for
this to go in via the mips tree.

Subject: MIPS: au1000_eth: Get ethernet address from platform_data

au1000_eth uses firmware calls to get a valid MAC address, and changes
it depending on platform device id.  This patch moves this logic out of
the driver into the platform device registration part, where boards with
supported chips can use whatever firmware interface they need; the default
implementation maintains compatibility with existing, YAMON-based firmware.

Subject: WATCHDOG: Add watchdog driver for OCTEON SOCs

The OCTEON is a MIPS64 based SOC family with an on chip watchdog unit.

The driver is split into two source files one for the C code and one
for assembly.  Assembly is needed to handle the NMI and then print the
machine state before the reboot is triggered.

+ * The OCTEON watchdog has a maximum timeout of 2^32 * io_clock.
+ * For most systems this is less than 10 seconds, so to allow for
+ * software to request longer watchdog heartbeats, we maintain software
+ * counters to count multiples of the base rate.  If the system locks
+ * up in such a manner that we can not run the software counters, the
+ * only result is a watchdog reset sooner than was requested.  But
+ * that is OK, because in this case userspace would likely not be able
+ * to do anything anyhow.
+ *
+ * The hardware watchdog interval we call the period.  The OCTEON
+ * watchdog goes through several stages, after the first period an
+ * irq is asserted, then if it is not reset, after the next period NMI
+ * is asserted, then after an additional period a chip wide soft reset.
+ * So for the software counters, we reset watchdog after each period
+ * and decrement the counter.  But for the last two periods we need to
+ * let the watchdog progress to the NMI stage so we disable the irq
+ * and let it proceed.  Once in the NMI, we print the register state
+ * to the serial port and then wait for the reset.
+ *
+ * A watchdog is maintained for each CPU in the system, that way if
+ * one CPU suffers a lockup, we also get a register dump and reset.
+ * The userspace ping resets the watchdog on all CPUs.
+ *
+ * Before userspace opens the watchdog device, we still run the
+ * watchdogs to catch any lockups that may be kernel related.

Subject: vt,console,kdb: automatically set kdb LINES variable

The kernel console interface stores the number of lines it is
configured to use. The kdb debugger can greatly benefit by knowing how
many lines there are on the console for the pager functionality
without having the end user compile in the setting or have to
repeatedly change it at run time.

Subject: fb: add hooks to handle KDB enter/exit

Add fb ops to handle enter/exit of the kernel debugger.  If present, the
fb core will register them with KGDB and they'll be called when the
debugger is entered and exited.  The new functions are responsible for
switching to an appropriate debug framebuffer and restoring the
interrupted state at exit time.

Subject: i915: when kgdb is active display compression should be off

If the HW compression is left on, the call backs from the HW will
crash the kernel.  The only time this code is called is when kernel
mode setting is in use with kgdb and the kdb shell.

The atomic display pipe handler callback will reset everything when
kgdb restores kernel to the run state.

Subject: drm_fb_helper: Preserve capability to use atomic kms

Commit 5349ef3127c77075ff70b2014f17ae0fbcaaf199 (drm/fb: fix
FBIOGET/PUT_VSCREENINFO pixel clock handling) changed the logic of
when a pixclock was valid vs invalid.

The atomic kernel mode setting used by the kernel debugger relies upon
the drm_fb_helper_check_var() to always return -EINVAL.  Until a
better solution exists, this behavior will be restored.
