* drm/i915: Remove stored gtt_alignmentChris Wilson2009-09-17
| | | | | | | | | There is no need to store the gtt_alignment as it is either explicitly set according to the hardware requirements (e.g. scanout) or the minimum alignment is computed on demand.

* drm/i915: fix startup hang on some non-mobile platformsJesse Barnes2009-09-17
| | | | | | | | | | | | | Due to a bogus FBC support check and failing to check for FBC support in the right places, mode setting on non-mobile platforms could fail and hang in the FBC disable routine. Fix it up. This fix highlights the need for cleanups in this area (function pointers and better feature support checks). Patches for that to follow.

* drm/i915: fix suspend/resume breakage in lid notifierJesse Barnes2009-09-17
| | | | | | | | | | | | | | | We now unconditionally restore the mode at lid open time since some platforms turn off the panel, pipes or other display elements when the lid is closed. There's a problem with doing this at resume time however. At resume time, we'll get a lid event, but restoring the mode at that time may not be safe (e.g. if we get the lid event before global state has been restored), so check the suspended state and make sure our restore is locked against other mode updates.

* drm/i915: Make dev_priv->mm.wedged an atomic_tBen Gamari2009-09-17
| | | | | | | | | There is a very real possibility that multiple CPUs will notice that the GPU is wedged. This introduces all sorts of potential race conditions.

* drm/i915: Add hangcheck timerBen Gamari2009-09-17
| | | | | | | | | | | | | | | | | | | | | | | We set a periodic timer to check on the GPU, resetting it every time a batch is completed. If the timer elapses, we check acthd. If acthd hasn't changed in two timer periods, we assume the chip is wedged. This is implemented in such a way that it leaves the option open to employ adaptive timer intervals in the future. One could wait until several timer periods have elapsed before declaring the chip dead. If the chip comes back after several periods but before the "dead" threshold, the timer interval or dead threshold could be raised. It is important to note that while checking for active requests, we need to account for the fact that requests are removed from the list (i.e. retired) in a deferred work queue handler. This means that merely checking for an empty request_list is insufficient; the list could be non-empty yet the GPU still idle, causing the hangcheck timer to incorrectly mark the GPU as wedged (it took me a while to figure that out---sigh...)

* drm/i915: make i915_seqno_passed non-staticBen Gamari2009-09-17

* drm/i915: Refactor save/restore codeBen Gamari2009-09-17
| | | | | | | | | We move the display-specific code into it's own functions, called from the general GPU state save/restore functions. This will be needed later by the GPU reset code. Signed-off-by: Ben Gamari <bgamari.foss@gmail.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
* drm/i915: Check whether chip is wedged in i915_wait_request()Ben Gamari2009-09-17
| | | | | | | | | | i915_wait_request() only checks mm.wedged after it interacts with the hardware, generally causing the driver to lock up waiting for a wedged chip. Make sure we check mm.wedged as the first thing we do.

* drm/i915: Only destroy a constructed mmap offsetChris Wilson2009-09-11
| | | | | | | | | | | | | | | | | | drm_ht_remove_item() does not handle removing an absent item and the hlist in particular is incorrectly initialised. The easy remedy is simply skip calling i915_gem_free_mmap_offset() unless we have actually created the offset and associated ht entry. This also fixes the mishandling of a partially constructed offset which leaves pointers initialized after freeing them along the i915_gem_create_mmap_offset() error paths. In particular this should fix the oops found here: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/415357/comments/8 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net> Cc: stable@kernel.org
* agp/intel: Fix the pre-9xx chipset flush.Eric Anholt2009-09-11
| | | | | | | | | | | | | | | | | | | | | | | Ever since we enabled GEM, the pre-9xx chipsets (particularly 865) have had serious stability issues. Back in May a wbinvd was added to the DRM to work around much of the problem. Some failure remained -- easily visible by dragging a window around on an X -retro desktop, or by looking at bugzilla. The chipset flush was on the right track -- hitting the right amount of memory, and it appears to be the only way to flush on these chipsets, but the flush page was mapped uncached. As a result, the writes trying to clear the writeback cache ended up bypassing the cache, and not flushing anything! The wbinvd would flush out other writeback data and often cause the data we wanted to get flushed, but not always. By removing the setting of the page to UC and instead just clflushing the data we write to try to flush it, we get the desired behavior with no wbinvd. This exports clflush_cache_range(), which was laying around and happened to basically match the code I was otherwise going to copy from the DRM.

* drm/i915: framebuffer compression for pre-GM45Jesse Barnes2009-09-10
| | | | | | | | | | | | | | | This patch adds framebuffer compression (good for about ~0.5W power savings in the best case) support for pre-GM45 chips. GM45+ have a new, more flexible FBC scheme that will be added in a separate patch. FBC can't always be enabled: the compressed buffer must be physically contiguous and reside in stolen space. So if you have a large display and a small amount of stolen memory, you may not be able to take advantage of FBC. In some cases, a BIOS setting controls how much stolen space is available. Increasing this to 8 or 16M can help. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>
