drm: stop information leak of old kernel stack.

2010-08-26T23:44:02Z

commit b9f0aee83335db1f3915f4e42a5e21b351740afd upstream. non-critical issue, CVE-2010-2803 Userspace controls the amount of memory to be allocate, so it can get the ioctl to allocate more memory than the kernel uses, and get access to kernel stack. This can only be done for processes authenticated to the X server for DRI access, and if the user has DRI access. Fix is to just memset the data to 0 if the user doesn't copy into it in the first place. Reported-by: Kees Cook Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/radeon/kms: fix GTT/VRAM overlapping test

2010-08-26T23:44:02Z

commit 2cbeb4efc2b9739fe6019b613ae658bd2119a3eb upstream. GTT/VRAM overlapping test had a typo which leaded to not detecting case when vram_end > gtt_end. This patch fix the logic and should fix #16574 Signed-off-by: Jerome Glisse Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/radeon/kms: fix sideport detection on newer rs880 boards

2010-08-26T23:44:01Z

commit 4b80d954a7e54c13a5063af18d01719ad6a0daf3 upstream. The meaning of ucMemoryType changed on recent boards, however, ulBootUpSidePortClock should be set properly across all boards. Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/radeon/kms/DCE3+: switch pads to ddc mode when going i2c

2010-08-26T23:44:00Z

commit 5786e2c5a3f519647c50bbc276e45d36a704415a upstream. The pins for ddc and aux are shared so you need to switch the mode when doing ddc. The ProcessAuxChannel table already sets the pin mode to DP. This should fix unreliable ddc issues on DP ports using non-DP monitors.

commit 0537398b211b4f040564beec458e23571042d335 upstream. Looks like this got copied from the ddx wrong. Cc: Benjamin Herrenschmidt Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie Signed-off-by: Greg Kroah-Hartman

drm/i915: i8xx also doesn't like multiple oustanding pageflips

2010-08-26T23:43:33Z

commit 6146b3d61925116e3fecce36c2fd873665bd6614 upstream. My i855GM suffers from a 80k/s interrupt storm without this. So add 2nd gen to the list of things that don't like more than one outstanding pageflip request. Furthermore I've changed the busy loop into a ringbuffer wait. Busy-loops that don't check whether the chip died are simply evil. And performance should actually improve, because there's usually a decent amount of rendering queued on the gpu, hopefully rendering that MI_WAIT into a noop by the time it's executed. The current code holds dev->struct_mutex while executing this loop, hence stalling all other gem activity anyway.

drm/i915: fixup pageflip ringbuffer commands for i8xx

2010-08-26T23:43:33Z

commit 69d0b96c095468526009cb3104eee561c9252a84 upstream. Add a new path for 2nd gen chips that uses the commands for i81x chips (where public docs do exist) augmented with the plane bits from i915. It seems to work and doesn't result in a black screen like before.
