2016-07-19Merge remote-tracking branch 'airlied/drm-next' into topic/drm-miscDaniel Vetter662-11635/+21452
Backmerge drm-next to be able to apply Chris' connector_unregister_all cleanup (need latest i915 and sun4i state for that). Also there's a trivial conflict in ttm_bo.c that git rerere fails to remember. Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
2016-07-19drm/ttm: Delete an unnecessary check before the function call "ttm_tt_destroy"Markus Elfring1-3/+1
The ttm_tt_destroy() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.

2016-07-18drm/vgem: Attach sw fences to exported vGEM dma-buf (ioctl)Chris Wilson4-1/+334
vGEM buffers are useful for passing data between software clients and hardware renders. By allowing the user to create and attach fences to the exported vGEM buffers (on the dma-buf), the user can implement a deferred renderer and queue hardware operations like flipping and then signal the buffer readiness (i.e. this allows the user to schedule operations out-of-order, but have them complete in-order). This also makes it much easier to write tightly controlled testcases for dma-buf fencing and signaling between hardware drivers. v2: Don't pretend the fences exist in an ordered timeline, but allocate a separate fence-context for each fence so that the fences are unordered. v3: Make the debug output more interesting, and show the signaled status. v4: Automatically signal the fence to prevent userspace from indefinitely hanging drivers.

2016-07-16drm/vc4: Add support for branching in shader validation.Eric Anholt4-17/+283
We're already checking that branch instructions are between the start of the shader and the proper PROG_END sequence. The other thing we need to make branching safe is to verify that the shader doesn't read past the end of the uniforms stream. To do that, we require that at any basic block reading uniforms have the following instructions: load_imm temp, <next offset within uniform stream> add unif_addr, temp, unif The instructions are generated by userspace, and the kernel verifies that the load_imm is of the expected offset, and that the add adds it to a uniform. We track which uniform in the stream that is, and at draw call time fix up the uniform stream to have the address of the start of the shader's uniforms at that location.

2016-07-16drm/vc4: Add a bitmap of branch targets during shader validation.Eric Anholt2-2/+124
This isn't used yet, it's just a first step toward loop validation. During the main parsing of instructions, we need to know when we hit a new basic block so that we can reset validated state. v2: Fix a stray semicolon after an if block. (caught by kbuild test).
