* drm/exynos: add property for plane zposJoonyoung Shim2012-07-271-9/+0
| | | | | | | | | | | The exynos drm driver used a specific ioctl - DRM_EXYNOS_PLANE_SET_ZPOS to set zpos of plane. It can be substitute to property of plane. This patch adds a property for plane zpos and removes DRM_EXYNOS_PLANE_SET_ZPOS ioctl.

* | drm/sis: fixup sis_mm ioctl structsDaniel Vetter2012-07-191-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

|\ \ | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I want to merge the "no more fake agp on gen6+" patches into drm-intel-next (well, the last pieces). But a patch in 3.5-rc4 also adds a new use of dev->agp. 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". The only tricky part is to keep the order correct wrt the unwind code in case of errors in intel_ringbuffer.c (and the MI_DISPLAY_FLIP #defines in i915_reg.h together, obviously).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Low four bits are downstream port count. High bit indicates peer OUI support. OUI matching will allow us to do additional per-sink handling for things like DP->VGA bandwidth limits or (hopefully) the iMac-as- display hack.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DisplayPort has an escape hatch by which sources and sinks can identify each other. We would prefer not to notice this, but I suspect we're going to need to.

* | | drm/i915: wait render timeout ioctlBen Widawsky2012-05-251-0/+10
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. (Chris) v6: Return -ETIME instead of -EBUSY when timeout_ns is 0 (Daniel) Fix the commit message comment to be less ugly (Ben) Add a warning to check the return timespec (Ben) v7: Use DRM_AUTH for the ioctl.

* | drm/prime: expose capability flags for userspace.Dave Airlie2012-05-181-0/+4
| | | | | | | | | | | | | | | | | | | | | | This lets the kernel tell userspace if the device supports prime import/export. This is useful for -modesetting at least, but would be nice for other drivers. Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Dave Airlie <airlied@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | This way, we don't need to count every time, so we're a little bit faster and code is a little bit smaller. Change suggested by Ville Syrjälä.
