2012-07-19drm/sis: fixup sis_mm ioctl structsDaniel Vetter
Userspace uses long in quite a few places more than the kernel. Which gives me neat proof that I'm the only guy on this side of the galaxy who ever tried to run glxgears on a 64bit machine with sis graphics on linux. Note that the longs in drm_sis_mem_t aren't aligned properly, so this won't even work with 32bit userspace on 64bit kernel as-is. Hence the patch can't break that, either. Nope, I'm not nuts enough to write the 32bit ioctl compat layer for this and test it with some wine app. Even though hunting the ebay dungeons for a sis card actually supported by the mesa drivers casts some doubts on this ...

2012-07-16drm: Add colouring to the range allocatorChris Wilson
In order to support snoopable memory on non-LLC architectures (so that we can bind vgem objects into the i915 GATT for example), we have to avoid the prefetcher on the GPU from crossing memory domains and so prevent allocation of a snoopable PTE immediately following an uncached PTE. To do that, we need to extend the range allocator with support for tracking and segregating different node colours. This will be used by i915 to segregate memory domains within the GTT. v2: Now with more drm_mm helpers and less driver interference.

Hence the backmarge to sort this out, for otherwise drm-intel-next merged into Linus' tree would conflict in the relevant code, things would compile but nicely OOPS at driver load :( Conflicts in this merge are just simple cases of "both branches changed/added lines at the same place".

2012-06-12drm: increase DRM_OBJECT_MAX_PROPERTY to 24Paulo Zanoni
Before Kernel 3.5, no one was checking for the return value of drm_connector_attach_property, so we never noticed that we were unable to create some properties. Commit "drm: WARN() when drm_connector_attach_property fails" added a WARN when we fail to create a property, and the transition from "connector properties" to "object properties" changed the warning message a little bit. On i915 machines with many TV connectors we hit the maximum number of properties (since each TV connector uses a lot of properties), so we get a few backtraces in our logs. This commit increases the maximum number of properties to 24 hoping we'll have enough room for everybody. Chris suggested that we convert this code to "lists", but I believe this conversion can come after we make sure people's dmesgs are not spammed by our driver.

2012-06-06drm/i915: Inifite timeout for wait ioctlBen Widawsky
Change the ns_timeout parameter of the wait ioctl to a signed value. Doing this allows the kernel to provide an infinite wait when a timeout of less than 0 is provided. This mimics select/poll. Initially the parameter was meant to match up with the GL spec 1:1, but after being made aware of how much 2^64 - 1 nanoseconds actually is, I do not think anyone will ever notice the loss of 1 bit. The infinite timeout on waiting is similar to the existing i915 userspace interface with the exception that struct_mutex is dropped while doing the wait in this ioctl.

2012-05-25drm/i915: wait render timeout ioctlBen Widawsky
This helps implement GL_ARB_sync but stops short of allowing full blown sync objects. Finally we can use the new timed seqno waiting function to allow userspace to wait on a buffer object with a timeout. This implements that interface. The IOCTL will take as input a buffer object handle, and a timeout in nanoseconds (flags is currently optional but will likely be used for permutations of flush operations). Users may specify 0 nanoseconds to instantly check. The wait ioctl with a timeout of 0 reimplements the busy ioctl. With any non-zero timeout parameter the wait ioctl will wait for the given number of nanoseconds on an object becoming unbusy. Since the wait itself does so holding struct_mutex the object may become re-busied before this completes. A similar but shorter race condition exists in the busy ioctl. v2: ETIME/ERESTARTSYS instead of changing to EBUSY, and EGAIN (Chris) Flush the object from the gpu write domain (Chris + Daniel) Fix leaked refcount in good case (Chris) Naturally align ioctl struct (Chris) v3: Drop lock after getting seqno to avoid ugly dance (Chris) v4: check for 0 timeout after olr check to allow polling (Chris) v5: Updated the comment.

2012-05-17drm/exynos: add G2D driverJoonyoung Shim
Changelog v3: - use __u64 instead of pointer in ioctl struct. The G2D is a 2D graphic accelerator that supports Bit Block Transfer. This G2D driver is exynos drm specific and supports only G2D(version 4.1) of later Exynos series from Exynos4X12 because supporting DMA. The G2D is performed by two tasks simply. 1. Configures the rendering parameters, such as foreground color and coordinates data by setting the drawing context registers. 2. Start the rendering process by setting thre relevant command registers accordingly. The G2D version 4.1 supports DMA mode as host interface. User can make command list to reduce HOST(ARM) loads. The contents of The command list is setted to relevant registers of G2D by DMA. The command list is composed Header and command sets and Tail. - Header: The number of command set(4Bytes) - Command set: Register offset(4Bytes) + Register data(4Bytes) - Tail: Pointer of base address of the other command list(4Bytes) By Tail field, the G2D can process many command lists without halt at one go. The G2D has following the rendering pipeline. --> Primitive Drawing --> Rotation --> Clipping --> Bilinear Sampling --> Color Key --> ROP --> Mask Operation --> Alpha Blending --> Dithering --> FrameBuffer And supports various operations from the rendering pipeline. - copy - fast solid color fill - window clipping - rotation - flip - 4 operand raster operation(ROP4) - masking operation - alpha blending - color key - dithering - etc User should make the command list to data and registers needed by operation to use. The Exynos G2D driver only manages the command lists received from user. Some registers needs memory base address(physical address) of image. User doesn't know its physical address, so fills the gem handle of that memory than address to command sets, then G2D driver converts it to memory base address. We adds three ioctls and one event for Exynos G2D. - ioctls DRM_EXYNOS_G2D_GET_VER: get the G2D hardware version DRM_EXYNOS_G2D_SET_CMDLIST: set the command list from user to driver DRM_EXYNOS_G2D_EXEC: execute the command lists setted to driver - event DRM_EXYNOS_G2D_EVENT: event to give notification completion of the command list to user Signed-off-by: Joonyoung Shim <jy0922.shim@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
