      drm/i915: Fix tiling corruption from pipelined fencing · 29c5a587
      Chris Wilson authored
      ... even though it was disabled. A mistake in the handling of fence reuse
      caused us to skip the vital delay of waiting for the object to finish
      rendering before changing the register. This resulted in us changing the
      fence register whilst the bo was active and so causing the blits to
      complete using the wrong stride or even the wrong tiling. (Visually the
      effect is that small blocks of the screen look like they have been
      interlaced). The fix is to wait for the GPU to finish using the memory
      region pointed to by the fence before changing it.

      drm/i915: Re-enable self-refresh · 7ccb4a53

      A broken implementation of is_pot() prevented the detection of when a
      singular pipe was enabled. Eric Anholt pointed out the existence of
      is_power_of_2() so use that instead of our broken code!

      drm/i915: Prevent racy removal of request from client list · 09bfa517
      Herton Ronaldo Krzesinski authored
      When i915_gem_retire_requests_ring calls i915_gem_request_remove_from_client,
      the client_list for that request may already be removed in i915_gem_release.
      So we may call twice list_del(&request->client_list), resulting in an
      oops like this report:

      [126167.232018] Call Trace:
      
      Unfortunately the call trace reported was cut, but looking at debug
      symbols the crash is at __list_del, when probably list_del is called
      twice on the same request->client_list, as the dereferenced value is
      LIST_POISON1 + 4, and by looking more at the debug symbols before
      list_del call it should have being called by
      i915_gem_request_remove_from_client
      
      And as I can see in the code, it seems we indeed have the possibility
      to remove a request->client_list twice, which would cause the above,
      because we do list_del(&request->client_list) on both
      i915_gem_request_remove_from_client and i915_gem_release
      
      As Chris Wilson pointed out, it's indeed the case:
      "(...) I had thought that the actual insertion/deletion was serialised
      under the struct mutex and the intention of the spinlock was to protect
      the unlocked list traversal during throttling. However, I missed that
      i915_gem_release() is also called without struct mutex and so we do need
      the double check for i915_gem_request_remove_from_client()."
      
      This change does the required check to avoid the duplicate remove of
      request->client_list.

      drm/i915: skip redundant operations whilst enabling pipes and planes · 00d70b15
      Chris Wilson authored
      If the pipe or plane is already enabled, then we do not need to enable
      it again and can skip the delay. Similarly if it is already disabled
      when we want to disable it, we can also skip it.
      
      This fixes a regression from b24e7179, which caused the LVDS
      output on one PineView machine to become corrupt after changing
      orientation several times.

      drm/kernel: vblank wait on crtc > 1 · 19b01b5f
      Ilija Hadzic authored
      Below is a patch against drm-next branch of 2.6.38-rc8+ kernel that adds
      the capability to wait on vblank events for CRTCs that are greater than 1
      and thus cannot be represented with primary/secondary flags in the legacy
      interface. It was discussed on the dri-devel list in these two threads:
      
      http://lists.freedesktop.org/archives/dri-devel/2011-March/009009.html
      http://lists.freedesktop.org/archives/dri-devel/2011-March/009025.html
      
      This patch extends the interface to drm_wait_vblank ioctl so that crtc>1
      can be represented. It also adds a new capability to drm_getcap ioctl so
      that the user space can check whether the new interface to drm_wait_vblank
      is supported (and fall back to the legacy interface if not)

      drm: Hold the mode mutex whilst probing for sysfs status · 007c80a5
      Chris Wilson authored
      As detect will use hw registers and may modify structures, it needs to be
      serialised by use of the dev->mode_config.mutex. Make it so.
      
      Otherwise, we may cause random crashes as the sysfs file is queried
      whilst a concurrent hotplug poll is being run. For example:

      drm/nouveau: fix __nouveau_fence_wait performance · bd35fe5a
      Marcin Slusarz authored
      Commit 21e86c1c ("drm/nouveau: remove
      cpu_writers lock") turned on lazy waits. Unfortunately
      __nouveau_fence_wait was not optimized for this case and on HZ=100
      kernel wasted up to 10 ms per call.
      
      Depending on application, it led to 10-30% FPS regression.
      
      Fix it.

      This also makes the fact we're giving 512MiB of GART space to all PCIE
      boards explicit, although the vast majority (if not all) of them will
      now have a ramin_rsvd_vram larger than 2MiB anyway.

      When "buffer in list" check does not pass, don't free validation lists - they were

      drm/i915: disable opregion lid detection for now. · bcd5023c
      Dave Airlie authored
      At least on my HP 2540p this is wrong at bootup, fine
      at any other time once a lid event has occured. This is due to
      _REG vs _INI ordering in the ACPI tables.

      drm/radeon: fix problem with changing active VRAM size. (v2) · 53595338
      Dave Airlie authored
      So we used to use lpfn directly to restrict VRAM when we couldn't
      access the unmappable area, however this was removed in
      93225b0d as it also restricted
      the gtt placements. However it was only later noticed that this
      broke on some hw.
      
      This removes the active_vram_size, and just explicitly sets it
      when it changes, TTM/drm_mm will always use the real_vram_size,
      and the active vram size will change the TTM size used for lpfn
      setting.
      
      We should re-work the fpfn/lpfn to per-placement at some point
      I suspect, but that is too late for this kernel.
      
      Hopefully this addresses:
      https://bugs.freedesktop.org/show_bug.cgi?id=35254
      
      v2: fix reported useful VRAM size to userspace to be correct.
