The invalid alignment was discovered after updating the write_domain on the object but before the object was placed on the active queue. So during the unwind process following the error, the now freed object attempts to flush its non-existent, but outstanding, GPU writes causing this use-after-free.

| * drm/i915: Change GEM throttling to be 20ms like the comment says.Eric Anholt2009-06-043-19/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | keithp didn't like the original 20ms plan because a cooperative client could be starved by an uncooperative client. There may even have been problems with cooperative clients versus cooperative clients. So keithp changed throttle to just wait for the second to last seqno emitted by that client. It worked well, until we started getting more round-trips to the server due to DRI2 -- the server throttles in BlockHandler, and so if you did more than one round trip after finishing your frame, you'd end up unintentionally syncing to the swap. Fix this by keeping track of the client's requests, so the client can wait when it has an outstanding request over 20ms old. This should have non-starving behavior, good behavior in the presence of restarts, and less waiting. Improves high-settings openarena performance on my GM45 by 50%.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | drm_helper_connector_dpms. Making the drm_crtc.c code recognize the DPMS property and invoke the connector->dpms function doesn't remove any capability from the driver while reducing code duplication. That just highlighted the problem with the existing DPMS functions which could turn off the connector, but failed to turn off any relevant crtcs. The new drm_helper_connector_dpms function manages all of that, using the drm_helper-specific crtc and encoder dpms functions, automatically computing the appropriate DPMS level for each object in the system. This fixes the current troubles in the i915 driver which left PLLs, pipes and planes running while in DPMS_OFF mode or even while they were unused.

| | | | | | | | | | | | | | | | | | | | | | When a GEM object is evicted from the GTT we set it to the CPU domain, as it might get swapped in and out or ever mmapped regularly. If the object is mmapped through the GTT it can still get evicted in this way by other objects requiring GTT space. When the GTT mapping is touched again we fault it back into the GTT, but fail to set it back to the GTT domain. This means we fail to flush any cached CPU writes to the pages backing the object which will then happen "eventually", typically after we write to the page through the uncached GTT mapping. [anholt: Note that userland does do a set_domain(GTT, GTT) when starting to access the GTT mapping. That covers getting the existing mapping of the object synchronized if it's bound to the GTT. But set_domain(GTT, GTT) doesn't do anything if the object is currently unbound. This fix covers the transition to being bound for GTT mapping.] Fixes glyph and other pixmap corruption during swapping. fd.o bug #21790 Signed-off-by: Kristian Høgsberg <krh@redhat.com> Signed-off-by: Eric Anholt <eric@anholt.net>

| | | | | | | | | | | | | | On the 865, but not the 855, the clflush we do appears to not actually make it out to the hardware all the time. An easy way to safely reproduce was X -retro, which would show that some of the blits involved in drawing the lovely root weave didn't make it out to the hardware. Those blits are 32 bytes each, and 1-2 would be missing at various points around the screen. Other experimentation (doing more clflush, doing more AGP chipset flush, poking at some more device registers to maybe trigger more flushing) didn't help. krh came up with the wbinvd as a way to successfully get all those blits to appear.

Additionally, we programmed that bad value into the register on 8xx, so the only pitch that would work correctly was 4096 (512-1023 pixels), while others would probably give bad rendering or hangs.

| * i915: support 8xx desktop cursorsJesse Barnes2009-05-223-8/+39
| | | | | | | | | | | | | | | | | | | | For some reason we never added 8xx desktop cursor support to the kernel. This patch fixes that.

| * drm/i915: allocate large pointer arrays with vmallocJesse Barnes2009-05-191-23/+15Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For awhile now, many of the GEM code paths have allocated page or object arrays with the slab allocator. This is nice and fast, but won't work well if memory is fragmented, since the slab allocator works with physically contiguous memory (i.e. order > 2 allocations are likely to fail fairly early after booting and doing some work). This patch works around the issue by falling back to vmalloc for >PAGE_SIZE allocations. This is ugly, but much less work than chaining a bunch of pages together by hand (suprisingly there's not a bunch of generic kernel helpers for this yet afaik). vmalloc space is somewhat precious on 32 bit kernels, but our allocations shouldn't be big enough to cause problems, though they're routinely more than a page. Note that this patch doesn't address the unchecked alloc-based-on-ioctl-args in GEM; that needs to be fixed in a separate patch. Also, I've deliberately ignored the DRM's "area" junk. I don't think anyone actually uses it anymore and I'm hoping it gets ripped out soon. [Updated: removed size arg to new free function. We could unify the free functions as well once the DRM mem tracking is ripped out.] fd.o bug #20152 (part 1/3) Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Eric Anholt <eric@anholt.net>
* | drm: Copy back ioctl data to userspace regardless of return code.Michel Dänzer2009-05-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | Fixes a regression from commit 9d5b3ffc42f7820e8ee07705496955e4c2c38dd9 ('drm: fixup some of the ioctl function exit paths'): The vblank ioctl needs to update the userspace parameters when interrupted by a signal, which was prevented by the return code check. This could cause the X server to hang in drmWaitVBlank(). Signed-off-by: Michel Dänzer <daenzer@vmware.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
