      drm/i915: Add support for interlaced display. · 734b4157
      由 Krzysztof Halasa 提交于 
      This doesn't change the clock limits (minimums), i.e. it won't make it
output 720x576 PAL nor 720x480 NTSC, but it will work with modes like
1080i etc. (including GLX and textured Xvideo, not sure about the
overlay).

Tested on i915 + analog VGA, it would be worth checking if newer chips
(and which ones) still support interlaced mode.

      drm/i915: add timeout to FBC disable waits · 9517a92f
      由 Jesse Barnes 提交于 
      FBC disable on 965 can take long enough to trigger latency checks in the
kernel so be sure to timeout after a reasonable period.

      drm/i915: implement BSD ring buffer V2 · d1b851fc
      由 Zou Nan hai 提交于 
      The BSD (bit stream decoder) ring is used for accessing the BSD engine
which decodes video bitstream for H.264 and VC1 on G45+.  It is
asynchronous with the render ring and has access to separate parts of
the GPU from it, though the render cache is coherent between the two.

      drm/i915: convert some gem structures to per-ring V2 · 852835f3
      由 Zou Nan hai 提交于 
      The active list and request list move into the ringbuffer structure,
so each can track its active objects in the order they are in that
ring.  The flushing list does not, as it doesn't matter which ring
caused data to end up in the render cache.  Objects gain a pointer to
the ring they are active on (if any).

      With the advent of the BSD ring, be clear about which ring this is.
The docs are pretty consistent with calling this the Render engine at

      drm/i915: Move ringbuffer-related code to intel_ringbuffer.c. · 62fdfeaf
      由 Eric Anholt 提交于 
      This is preparation for supporting multiple ringbuffers on Ironlake.
The non-copy-and-paste changes are:
- de-staticing functions
- I915_GEM_GPU_DOMAINS moving to i915_drv.h to be used by both files.
- i915_gem_add_request had only half its implementation
  copy-and-pasted out of the middle of it.

      drm/i915: Fail to load driver if KMS request without GEM · 79a78dd6
      由 Chris Wilson 提交于 
      The i915's implementation of KMS requires GEM in order to manage the
memory and execution domains of the framebuffer and associated
resources. By the point at which we detect broken a BIOS and need to
disable GEM, we have already registered ourselves as a KMS driver with
several subsystems. Rather than introducing a fragile unwind and attempt
to continue with UMS, spit out an error and unload the driver.
