v2: Userspace (notably xf86-video-{intel,ati}) became confused when drmSetInterfaceVersion() started returning -EBUSY as they used a second call (the first done in drmOpen()) to check their master credentials. Since userspace wants to be able to repeatedly call drmSetInterfaceVersion() allow them to do so. v3: Rebase to drm-core-next.

This connector attribute allows you to enable or disable underscan on a digital output to compensate for panels that automatically overscan (e.g., many HDMI TVs). Valid values for the attribute are: off - forces underscan off on - forces underscan on auto - enables underscan if an HDMI TV is connected, off otherwise default value is auto.

Prior to this patch the code was dividing the src_v by the dst_h and vice versa, rather than src_v/dst_v and src_h/dst_h. This could lead to problems in the calculation of the display watermarks. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

Some BIOSes will claim a large chunk of stolen space. Unless we reclaim it, our aperture for remapping buffer objects will be constrained. So clamp the stolen space to 32M and ignore the rest. Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15469 among others. Adding the ignored stolen memory back into the general pool using the memory hotplug code is left as an exercise for the reader.

The docs warn that to position the cursor such that no part of it is visible on the pipe is an undefined operation. Avoid such circumstances upon changing the mode, or at any other time, by unsetting the cursor if it moves out of bounds. "For normal high resolution display modes, the cursor must have at least a single pixel positioned over the active screen.” (p143, p148 of the hardware registers docs). Fixes: Bug 24748 - [965G] Graphics crashes when resolution is changed with KMS enabled https://bugs.freedesktop.org/show_bug.cgi?id=24748 v2: Only update the cursor registers if they change. v3: Fix the unsigned comparision of x,y against width,height. v4: Always set CUR.BASE or else the cursor may become corrupt.

When creating an object, we create the handle by which it is known to the process and which own the reference to the object. That reference to the new handle is what we want to transfer to the process, not the lost reference to the object; so free the local object reference *not* the process's handle reference. This brings i915_gem_object_create_ioctl() into line with drm_gem_open_ioctl() Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Eric Anholt <eric@anholt.net>

If we fail to flush outstanding GPU writes but return the memory to the system, we risk corrupting memory should the GPU recovery and complete those writes. On the other hand, if we bail early and free the object then we have a definite use-after-free and real memory corruption. Choose the lesser of two evils, since in order to recover from the hung GPU we need to completely reset it, those pending writes should never happen.

If during the freeing of an object the unbind is interrupted by a system call, which is quite possible if we have outstanding GPU writes that must be flushed, the unbind is silently aborted. This still leaves the AGP region and backing pages allocated, and perhaps more importantly, the object remains upon the various lists exposing us to memory corruption. I think this is the cause behind the use-after-free, such as Bug 15664 - Graphics hang and kernel backtrace when starting Azureus with Compiz enabled https://bugzilla.kernel.org/show_bug.cgi?id=15664 v2: Daniel Vetter reminded me that kernel space programming is never easy. We cannot simply spin to clear the pending signal and so must deferred the freeing of the object until later. v3: Run from the top level retire requests. v4: Tested with P(return -ERESTARTSYS)=.5 from i915_gem_do_wait_request() v5: Rebase against Eric's for-linus tree. v6: Refactor, split and add a comment about avoiding unbounded recursion.

The original i965, including the revised G35 and Q35, requires an alignment of 128K for the display surface with linear memory, so increase the requirement from 64k for these chipsets. For the later chipsets in the i965 family, only a 4k alignment is required. (So long as we do not start performing asynchronous flips.) Note the impact of this should be slight as on i965 we should be using a tiled frontbuffer for anything up to a 4096x4096 display. v2: compilation fixes and note that the docs do not exclude the G35 from the extra alignment.
