* drm/i915: Disable FBC on 915GM and 945GM.Robert Hooker2010-05-262-3/+3
| | | | | | | | | | | | | | commit 8d06a1e1e9c69244f08beb7d17146483f9dcd120 upstream. It is causing hangs after a suspend/resume cycle with the default powersave=1 module option on these chipsets since 2.6.32-rc.

* drm/i915: fix non-Ironlake 965 class crashesJesse Barnes2010-05-261-1/+1
| | | | | | | | | | | | | | | | | | | | | commit 1918ad77f7f908ed67cf37c505c6ad4ac52f1ecf upstream. My PIPE_CONTROL fix (just sent via Eric's tree) was buggy; I was testing a whole set of patches together and missed a conversion to the new HAS_PIPE_CONTROL macro, which will cause breakage on non-Ironlake 965 class chips. Fortunately, the fix is trivial and has been tested. Be sure to use the HAS_PIPE_CONTROL macro in i915_get_gem_seqno, or we'll end up reading the wrong graphics memory, likely causing hangs, crashes, or worse.

* drm/i915: use PIPE_CONTROL instruction on Ironlake and Sandy BridgeJesse Barnes2010-05-264-16/+152
| | | | | | | | | | | | | | | | | | | | commit e552eb7038a36d9b18860f525aa02875e313fe16 upstream. Since 965, the hardware has supported the PIPE_CONTROL command, which provides fine grained GPU cache flushing control. On recent chipsets, this instruction is required for reliable interrupt and sequence number reporting in the driver. So add support for this instruction, including workarounds, on Ironlake and Sandy Bridge hardware. https://bugs.freedesktop.org/show_bug.cgi?id=27108 Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Tested-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* drm/i915: fix tiling limits for i915 class hw v2Daniel Vetter2010-05-123-14/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit c36a2a6de59e4a141a68b7575de837d3b0bd96b3 upstream. Current code is definitely crap: Largest pitch allowed spills into the TILING_Y bit of the fence registers ... :( I've rewritten the limits check under the assumption that 3rd gen hw has a 3d pitch limit of 8kb (like 2nd gen). This is supported by an otherwise totally misleading XXX comment. This bug mostly resulted in tiling-corrupted pixmaps because the kernel allowed too wide buffers to be tiled. Bug brought to the light by the xf86-video-intel 2.11 release because that unconditionally enabled tiling for pixmaps, relying on the kernel to check things. Tiling for the framebuffer was not affected because the ddx does some additional checks there ensure the buffer is within hw-limits. v2: Instead of computing the value that would be written into the hw fence registers and then checking the limits simply check whether the stride is above the 8kb limit. To better document the hw, add some WARN_ONs in i915_write_fence_reg like I've done for the i830 case (using the right limits).

* i915 / PM: Fix hibernate regression caused by suspend/resume splittingRafael J. Wysocki2010-02-221-21/+9
| | | | | | | | | | | | | | | | | | | | | Commit 84b79f8d2882b0a84330c04839ed4d3cefd2ff77 (drm/i915: Fix crash while aborting hibernation) attempted to fix a regression introduced by commit cbda12d77ea590082edb6d30bd342a67ebc459e0 (drm/i915: implement new pm ops for i915), but it went too far trying to split the freeze/suspend and resume/thaw parts of the code. As a result, it introduced another regression, which only is visible on some systems. Fix the problem by merging i915_drm_suspend() with i915_drm_freeze() and moving some code from i915_resume() into i915_drm_thaw(), so that intel_opregion_free() and intel_opregion_init() are also executed in the freeze and thaw code paths, respectively.

Fix this issue by splitting the i915 suspend into a freeze part a suspend part, where the latter is not executed before creating a hibernation image, and the i915 resume into a "low-level" resume part and a thaw part, where the former is not executed after the image has been created.

* drm/i915: untangle page flip completionJesse Barnes2010-02-101-7/+9
| | | | | | | | | | | | | | | | | | When a new page flip is requested, we need to both queue an unpin for the current framebuffer, and also increment the flip pending count on the newly submitted buffer. At flip finish time, we need to unpin the old fb and decrement the flip pending count on the new buffer. The old code was conflating the two, and led to hangs when new direct rendered apps were started, replacing the existing frame buffer. This patch splits out the buffers and prevents the hangs.

| | | | | | | | | | | | | | | | | An untiled framebuffer must be aligned to 64k. This is normally handled by intel_pin_and_fence_fb_obj(), but the intelfb_create() likes to be different and do the pinning itself. However, it aligns the buffer object incorrectly for pre-i965 chipsets causing a PGTBL_ERR when it is installed onto the output.

* drm/i915: Update write_domains on active list after flush.Daniel Vetter2010-02-102-4/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before changing the status of a buffer with a pending write we will await upon a new flush for that buffer. So we can take advantage of any flushes posted whilst the buffer is active and pending processing by the GPU, by clearing its write_domain and updating its last_rendering_seqno -- thus saving a potential flush in deep queues and improves flushing behaviour upon eviction for both GTT space and fences. In order to reduce the time spent searching the active list for matching write_domains, we move those to a separate list whose elements are the buffers belong to the active/flushing list with pending writes. Orignal patch by Chris Wilson <chris@chris-wilson.co.uk>, forward-ported by me. In addition to better performance, this also fixes a real bug. Before this changes, i915_gem_evict_everything didn't work as advertised. When the gpu was actually busy and processing request, the flush and subsequent wait would not move active and dirty buffers to the inactive list, but just to the flushing list. Which triggered the BUG_ON at the end of this function. With the more tight dirty buffer tracking, all currently busy and dirty buffers get moved to the inactive list by one i915_gem_flush operation. I've left the BUG_ON I've used to prove this in there.

By not enabling NORETRY by default these paths can run the shrinker and take memory from the system (but not from our own inactive lists because our shrinker can not run whilst we hold the struct mutex) and this may allow the system to survive a little longer whilst our drivers consume all available memory.

| | | | | | | | | | | | | | | Many platform support this feature, and it can provide significant power savings when the reduced refresh rate is low. However, on some platforms a secondary (reduced) timing is provided but not actually supported by the hardware. This results in undesirable flicker at runtime. So disable the feature by default, but allow users to opt-in to the reduced clock behavior with a new module parameter, lvds_downclock, that can be set to 1 to enable the feature.

* drm/i915: Don't wait interruptible for possible plane buffer flushZhenyu Wang2010-01-123-1/+53
| | | | | | | | | | | | | | | | | | | When we setup buffer for display plane, we'll check any pending required GPU flush and possible make interruptible wait for flush complete. But that wait would be most possibly to fail in case of signals received for X process, which will then fail modeset process and put display engine in unconsistent state. The result could be blank screen or CPU hang, and DDX driver would always turn on outputs DPMS after whatever modeset fails or not. So this one creates new helper for setup display plane buffer, and when needing flush using uninterruptible wait for that. This one should fix bug like https://bugs.freedesktop.org/show_bug.cgi?id=24009. Also fixing mode switch stress test on Ironlake.

| | | | | | | | | | | | | | | | | | | | | | For some SDVO cards based on conexant chip, we can't read the EDID if we don't read the response after issuing SDVO DDC bus switch command. From the SDVO spec once when another I2C transaction is finished after completing the I2C transaction of issuing the bus switch command, it will be switched back to the SDVO internal state again. So we can't initiate a new I2C transaction to read the response after issuing the DDC bus switch command. Instead we should issue DDC bus switch command and read the response in the same I2C transaction. https://bugs.freedesktop.org/show_bug.cgi?id=23842 https://bugs.freedesktop.org/show_bug.cgi?id=24458 https://bugs.freedesktop.org/show_bug.cgi?id=24522 https://bugs.freedesktop.org/show_bug.cgi?id=24282 Signed-off-by: Zhao Yakui <yakui.zhao@intel.com> Tested-by: Sebastien Caty <sebastien.caty@mrnf.gouv.qc.ca> Signed-off-by: Eric Anholt <eric@anholt.net>
