During NVM upgrade process the host router is hot-removed for a short
while. During this time it is possible that the root port is moved into
D3cold which would be fine if the root port could trigger PME on itself.
However, many systems actually do not implement it so what happens is
that the root port goes into D3cold and never wakes up unless userspace
does PCI config space access, such as running 'lscpi'.
For this reason we explicitly prevent the root port from runtime
suspending during NVM upgrade.

This is a longstanding issue: if the vmbus upper-layer drivers try to
consume too many GPADLs, the host may return with an error
0xC0000044 (STATUS_QUOTA_EXCEEDED), but currently we forget to check
the creation_status, and hence we can pass an invalid GPADL handle
into the OPEN_CHANNEL message, and get an error code 0xc0000225 in
open_info->response.open_result.status, and finally we hang in
vmbus_open() -> "goto error_free_info" -> vmbus_teardown_gpadl().
With this patch, we can exit gracefully on STATUS_QUOTA_EXCEEDED.

Malicious code can attempt to free buffers using the BC_FREE_BUFFER
ioctl to binder. There are protections against a user freeing a buffer
while in use by the kernel, however there was a window where
BC_FREE_BUFFER could be used to free a recently allocated buffer that
was not completely initialized. This resulted in a use-after-free
detected by KASAN with a malicious test program.
This window is closed by setting the buffer's allow_user_free attribute
to 0 when the buffer is allocated or when the user has previously freed
it instead of waiting for the caller to set it. The problem was that
when the struct buffer was recycled, allow_user_free was stale and set
to 1 allowing a free to go through.

The vsc85xx_default_config function called in the vsc85xx_config_init
function which is used by VSC8530, VSC8531, VSC8540 and VSC8541 PHYs
mistakenly calls phy_read and phy_write in-between phy_select_page and
phy_restore_page.
phy_select_page and phy_restore_page actually take and release the MDIO
bus lock and phy_write and phy_read take and release the lock to write
or read to a PHY register.
Let's fix this deadlock by using phy_modify_paged which handles
correctly a read followed by a write in a non-standard page.

team_notify_peers() will send ARP and NA to notify peers. team_mcast_rejoin()
will send multicast join group message to notify peers. We should do this when
enabling/changed to a new port. But it doesn't make sense to do it when a port
is disabled.
On the other hand, when we set mcast_rejoin_count to 2, and do a failover,
team_port_disable() will increase mcast_rejoin.count_pending to 2 and then
team_port_enable() will increase mcast_rejoin.count_pending to 4. We will send
4 mcast rejoin messages at latest, which will make user confused. The same
with notify_peers.count.
Fix it by deleting team_notify_peers() and team_mcast_rejoin() in
team_port_disable().

We don't disable VIRTIO_NET_F_GUEST_CSUM if XDP was set. This means we
can receive partial csumed packets with metadata kept in the
vnet_hdr. This may have several side effects:
- It could be overridden by header adjustment, thus is might be not
correct after XDP processing.
- There's no way to pass such metadata information through
XDP_REDIRECT to another driver.
- XDP does not support checksum offload right now.
So simply disable guest csum if possible in this the case of XDP.

interrupts
In the original ftmac100_interrupt(), the interrupts are only disabled when
the condition "netif_running(netdev)" is true. However, this condition
causes kerenl hang in the following case. When the user requests to
disable the network device, kernel will clear the bit __LINK_STATE_START
from the dev->state and then call the driver's ndo_stop function. Network
device interrupts are not blocked during this process. If an interrupt
occurs between clearing __LINK_STATE_START and stopping network device,
kernel cannot disable the interrupts due to the condition
"netif_running(netdev)" in the ISR. Hence, kernel will hang due to the
continuous interruption of the network device.
In order to solve the above problem, the interrupts of the network device
should always be disabled in the ISR without being restricted by the
condition "netif_running(netdev)".

If we need to force a full plane update before userspace/fbdev
have given us a proper plane state we should try to maintain the
current plane state as much as possible (apart from the parts
of the state we're trying to fix up with the plane update).
To that end add basic readout for the plane rotation and
maintain it during the initial fb takeover.

If we force a plane update to fix up our half populated plane state
we'll also force on the pipe gamma for the plane (since we always
enable pipe gamma currently). If the BIOS hasn't programmed a sensible
LUT into the hardware this will cause the image to become corrupted.
Typical symptoms are a purple/yellow/etc. flash when the driver loads.
To avoid this let's program something sensible into the LUT when
we do the plane update. In the future I plan to add proper plane
gamma enable readout so this is just a temporary measure.

Many HP AMD based laptops contain an SMB0001 device like this:
Device (SMBD)
{
Name (_HID, "SMB0001") // _HID: Hardware ID
Name (_CRS, ResourceTemplate () // _CRS: Current Resource Settings
{
IO (Decode16,
0x0B20, // Range Minimum
0x0B20, // Range Maximum
0x20, // Alignment
0x20, // Length
)
IRQ (Level, ActiveLow, Shared, )
{7}
})
}
The legacy style IRQ resource here causes acpi_dev_get_irqresource() to
be called with legacy=true and this message to show in dmesg:
ACPI: IRQ 7 override to edge, high
This causes issues when later on the AMD0030 GPIO device gets enumerated:
Device (GPIO)
{
Name (_HID, "AMDI0030") // _HID: Hardware ID
Name (_CID, "AMDI0030") // _CID: Compatible ID
Name (_UID, Zero) // _UID: Unique ID
Method (_CRS, 0, NotSerialized) // _CRS: Current Resource Settings
{
Name (RBUF, ResourceTemplate ()
{
Interrupt (ResourceConsumer, Level, ActiveLow, Shared, ,, )
{
0x00000007,
}
Memory32Fixed (ReadWrite,
0xFED81500, // Address Base
0x00000400, // Address Length
)
})
Return (RBUF) /* \_SB_.GPIO._CRS.RBUF */
}
}
Now acpi_dev_get_irqresource() gets called with legacy=false, but because
of the earlier override of the trigger-type acpi_register_gsi() returns
-EBUSY (because we try to register the same interrupt with a different
trigger-type) and we end up setting IORESOURCE_DISABLED in the flags.
The setting of IORESOURCE_DISABLED causes platform_get_irq() to call
acpi_irq_get() which is not implemented on x86 and returns -EINVAL.
resulting in the following in dmesg:
amd_gpio AMDI0030:00: Failed to get gpio IRQ: -22
amd_gpio: probe of AMDI0030:00 failed with error -22
The SMB0001 is a "virtual" device in the sense that the only way the OS
interacts with it is through calling a couple of methods to do SMBus
transfers. As such it is weird that it has IO and IRQ resources at all,
because the driver for it is not expected to ever access the hardware
directly.
The Linux driver for the SMB0001 device directly binds to the acpi_device
through the acpi_bus, so we do not need to instantiate a platform_device
for this ACPI device. This commit adds the SMB0001 HID to the
forbidden_id_list, avoiding the instantiating of a platform_device for it.
Not instantiating a platform_device means we will no longer call
acpi_dev_get_irqresource() for the legacy IRQ resource fixing the probe of
the AMDI0030 device failing.

Writeback connectors do not produce any on-screen output and require
special care for use. Such connectors are hidden from enumeration in
DRM resources by default, but they are still picked-up by fbdev.
This makes rather little sense since fbdev is not really adapted for
dealing with writeback.
Moreover, this is also a source of issues when userspace disables the
CRTC (and associated plane) without detaching the CRTC from the
connector (which is hidden by default). In this case, the connector is
still using the CRTC, leading to am "enabled/connectors mismatch" and
eventually the failure of the associated atomic commit. This situation
happens with VC4 testing under IGT GPU Tools.
Filter out writeback connectors in the fbdev helper to solve this.

Under moderate amounts of GPU stress, we can observe on Bearlake and
Pineview (later gen3 models) that we execute the following batch buffer
before the write into the batch is coherent. Adding extra (tested with
upto 32x) MI_FLUSH to either the invalidation, flush or both phases does
not solve the incoherency issue with the relocations, but emitting the
MI_STORE_DWORD_IMM twice does. So be it.
