      drm: add some caps for userspace to discover more info for dumb KMS driver (v2) · 019d96cb
      Dave Airlie 提交于
      For the simple KMS driver case we need some more info about what the preferred
      depth and if a shadow framebuffer is preferred.
      
      I've only added this for intel/radeon which support the dumb ioctls so far.
      
      If you need something really fancy you should be writing a real X.org driver.
      
      v2: drop cursor information, just return an error from the cursor ioctls
      and we can make userspace fallback to sw cursor in that case, cursor
      info was getting too messy, best to start smaller.

      drm: move pci bus master enable into driver. · 466e69b8
      Dave Airlie 提交于
      The current enabling of bus mastering in the drm midlayer allows a large
      race condition under kexec. When a kexec'ed kernel re-enables bus mastering
      for the GPU, previously setup dma blocks may cause writes to random pieces
      of memory. On radeon the writeback mechanism can cause these sorts of issues.
      
      This patch doesn't fix the problem, but it moves the bus master enable under
      the individual drivers control so they can move enabling it until later in
      their load cycle and close the race.
      
      Fix for radeon kms driver will be in a follow-up patch.

      drm/i915/lvds: Always use the presence pin for LVDS on PCH · f3cfcba6
      Chris Wilson 提交于
      With the introduction of the PCH, we gained an LVDS presence pin but we
      continued to use the existing logic that asserted that LVDS was only
      supported on certain mobile chipsets. However, there are desktop
      IronLake systems with LVDS attached which we fail to detect. So for PCH,
      trust the LVDS presence pin and quirk all the lying manufacturers.

      drm/i915: Record the in-flight requests at the time of a hang · 52d39a21
      Chris Wilson 提交于
      Being able to tally the list of outstanding requests with the sequence
      of commands in the ringbuffer is often useful evidence with respect to
      driver corruption.
      
      Note that since this is the umpteenth per-ring data structure to be added
      to the error state, I've coallesced the nearby loops (the ringbuffer and
      batchbuffer) into a single structure along with the list of requests.  A
      later task would be to refactor the ring register state into the same
      structure.

      drm/i915: Record the tail at each request and use it to estimate the head · a71d8d94
      Chris Wilson 提交于
      By recording the location of every request in the ringbuffer, we know
      that in order to retire the request the GPU must have finished reading
      it and so the GPU head is now beyond the tail of the request. We can
      therefore provide a conservative estimate of where the GPU is reading
      from in order to avoid having to read back the ring buffer registers
      when polling for space upon starting a new write into the ringbuffer.
      
      A secondary effect is that this allows us to convert
      intel_ring_buffer_wait() to use i915_wait_request() and so consolidate
      upon the single function to handle the complicated task of waiting upon
      the GPU. A necessary precaution is that we need to make that wait
      uninterruptible to match the existing conditions as all the callers of
      intel_ring_begin() have not been audited to handle ERESTARTSYS
      correctly.
      
      By using a conservative estimate for the head, and always processing all
      outstanding requests first, we prevent a race condition between using
      the estimate and direct reads of I915_RING_HEAD which could result in
      the value of the head going backwards, and the tail overflowing once
      again. We are also careful to mark any request that we skip over in
      order to free space in ring as consumed which provides a
      self-consistency check.
      
      Given sufficient abuse, such as a set of unthrottled GPU bound
      cairo-traces, avoiding the use of I915_RING_HEAD gives a 10-20% boost on
      Sandy Bridge (i5-2520m):
        firefox-paintball  18927ms -> 15646ms: 1.21x speedup
        firefox-fishtank   12563ms -> 11278ms: 1.11x speedup
      which is a mild consolation for the performance those traces achieved from
      exploiting the buggy autoreported head.
      
      v2: Add a few more comments and make request->tail a conservative
      estimate as suggested by Daniel Vetter.

      drm/i915: add a "force-dvi" HDMI audio mode · b1d7e4b4

      When HDMI-DVI converter is used, it's not only necessary to turn off

      add a new "force-dvi" audio mode:
      
      	xrandr --output HDMI1 --set audio force-dvi
      
      Note that most users won't need to set this and happily rely on the EDID
