2012-08-13drm/radeon: do not reenable crtc after moving vram start addressJerome Glisse
It seems we can not update the crtc scanout address. After disabling crtc, update to base address do not take effect after crtc being reenable leading to at least frame being scanout from the old crtc base address. Disabling crtc display request lead to same behavior. So after changing the vram address if we don't keep crtc disabled we will have the GPU trying to read some random system memory address with some iommu this will broke the crtc engine and will lead to broken display and iommu error message. So to avoid this, disable crtc. For flicker less boot we will need to avoid moving the vram start address.

2012-08-06drm/i915: Workaround hang with BSD and forcewake on SandyBridgeChris Wilson
For reasons that are not apparent to anybody, 990bbdadaba (drm/i915: Group the GT routines together in both code and vtable) breaks the use of the BitStream Decoder ring on SandyBridge. The active ingredient of that patch is the conversion from a udelay(10) to a udelay(1) in the busy-wait loop of waiting for the forcewake acknowledge. If we restore that udelay(10) or insert another udelay(1) afterwards (or any wait longer than 250ns) everything works again. An alternative is also to remove any delay from the busy-wait loop. Given that in the atomic sections we want to complete the wait as quick as possible to avoid blocking the CPU for too long, it makes sense to remove the delay altogether and simply spin on the exit condition until it completes. So we replace the udelay(1) with cpu_relax().

2012-08-05drm/i915: Don't forget to apply SNB PIPE_CONTROL GTT workaround.Eric Anholt
If a buffer that was the target of a PIPE_CONTROL from userland was a reused one that hadn't been evicted which had not previously had this workaround applied, then the early return for a correct presumed_offset in this function meant we would not bind it into the GTT and the write would land somewhere else.

2012-07-27drm/i915: fix forcewake related hangs on snbDaniel Vetter
... by adding seemingly redudant posting reads. This little dragon lair exploded the first time around when we've refactored the code a bit to use the common wait_for_atomic_us in "drm/i915: Group the GT routines together in both code and vtable", which caused QA to file fdo bug #51738. Chris Wilson entertained a few approaches to fixing #51738: Replacing the udelay(1) with the previously-used udelay(10) (or any other "sufficiently larger" delay), adding a posting read, or ditching the delay completely and using cpu_relax. We went with the cpu_relax and "915: Workaround hang with BSD and forcewake on SandyBridge". Which blew up in fdo bug #52424, but adding the posting read while still using cpu_relax seems to also fix that, it looks like the posting read is the important ingriedient to fix these rc6 related hangs on snb. Popular theories as to why this is like it is include: - A herd of pink elephants got royally angered somehow. - The gpu has internally different functional units and judging by the register offsets, the forcewake request register and the forcewake ack registers are _not_ in the same functional unit (or at least aren't reached through the same routes). Hence the posting read syncs up with the wrong block and gets the entire gpu confused. - ... As a minimal ducttape fix for 3.6, let's just put these posting reads into place again. We can try fancier approaches (like adding back the cpu_relax instead of the udelay) in -next.
