2010-08-23drm/radeon/kms: try to detect tv vs monitor for underscanAlex Deucher1-1/+14
When enabling underscan for hdmi monitors, attempt to detect whether we are driving a TV or a monitor. The should hopefully prevent underscan from being enabled on monitors attached via hdmi that do not overscan the image. Only enable underscan if the mode is a common hdtv mode (480p, 720p, etc.).

2010-08-21drm/i915: Remove the conflicting BUG_ON()Chris Wilson1-2/+0
We now attempt to free "active" objects following a GPU hang as either the GPU will be reset or the hang is permenant. In either case, the GPU writes will not be flushed to main memory and it should be safe to return that memory back to the system. The BUG_ON(active) is thus overkill and can erroneously fire after a EIO. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net>

Like on Sandybridge, disabling the DAC here when doing CRT load detect avoids forever hangs waiting on the hardware. test procedure on HP 2740p: boot with no VGA plugged in, start X, plug in VGA monitor (1280x1024) chvt 3 machine hangs waiting forever.

2010-08-21drm/i915: wait for actual vblank, not just 20msJesse Barnes7-30/+69
Waiting for a hard coded 20ms isn't always enough to make sure a vblank period has actually occurred, so add code to make sure we really have passed through a vblank period (or that the pipe is off when disabling). This prevents problems with mode setting and link training, and seems to fix a bug like https://bugs.freedesktop.org/show_bug.cgi?id=29278, but on an HP 8440p instead.

2010-08-20drm/radeon/kms: rework radeon_dp_detect() logicAlex Deucher1-10/+11
If the connector is eDP, it can only be DP, not TMDS. Always set the detected sink type. If the sink is detected as non-DP, but there is no EDID, you can still manually force the port on. If the sink type is DP and there's no DPCD, there's no way to force the monitor on since you need both ends to train the link.

2010-08-20drm/radeon/kms/DCE3+: switch pads to ddc mode when going i2cAlex Deucher1-0/+7

2010-08-18drm/i915: fix VGA plane disable for Ironlake+Jesse Barnes1-28/+27
We need to use I/O port instructions to access VGA registers on Ironlake+, and it doesn't hurt on other platforms, so switch the VGA plane disable function over to using them. Move it to init time as well while we're at it, no need to repeatedly disable the VGA plane with every mode set and DPMS event. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2010-08-18drm/i915: eDP mode set sequence correctionsJesse Barnes1-9/+8
We should disable the panel first when shutting down an eDP link. And when turning one on, the panel needs to be enabled before link training or eDP I/O won't be enabled. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2010-08-18drm/i915: add panel reset workaroundJesse Barnes1-1/+16
Ironlake requires that we clear the reset panel bit during power sequences and restore it afterwards. Uncondtionally add code to do that since it should be harmless on SNB+. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2010-08-17drm: block userspace under allocating buffer and having drivers overwrite it ↵Dave Airlie13-226/+236
(v2) With the current screwed but its ABI, ioctls for the drm, Linus pointed out that we could allow userspace to specify the allocation size, but we pass it to the driver which then uses it blindly to store a struct. Now if userspace specifies the allocation size as smaller than the driver needs, the driver can possibly overwrite memory. This patch restructures the driver ioctls so we store the structure size we are expecting, and make sure we allocate at least that size. The copy from/to userspace are still restricted to the size the user specifies, this allows ioctl structs to grow on both sides of the equation. Up until now we didn't really use the DRM_IOCTL defines in the kernel, so this cleans them up and adds them for nouveau. v2: fix nouveau pushbuf arg (thanks to Ben for pointing it out) Reported-by: Linus Torvalds <torvalds@linuxfoundation.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
2010-08-17drm: stop information leak of old kernel stack.Dave Airlie1-1/+3
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 <kees@ubuntu.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-08-17drm/nouveau: fix race condition when under memory pressureBen Skeggs3-10/+42
When VRAM is running out it's possible that the client's push buffers get evicted to main memory. When they're validated back in, the GPU may be used for the copy back to VRAM, but the existing synchronisation code only deals with inter-channel sync, not sync between PFIFO and PGRAPH on the same channel. This leads to PFIFO fetching from command buffers that haven't quite been copied by PGRAPH yet. This patch marks push buffers as so, and forces any GPU-assisted buffer moves to be done on a different channel, which triggers the correct synchronisation to happen before we submit them.
