2012-08-10drm/mgag200: fix G200ER pll picking algorithmDave Airlie
The original code was misported from the X driver, a) an int went to unsigned int, breaking the downward counting testm code b) the port did the vco/computed clock bits completely wrong. This fixes an infinite loop on modprobe on some Dell servers with the G200ER chipset variant. Found in internal testing. Cc: stable@vger.kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>

Commit 0136db586c028f71e7cc21cc183064ff0d5919c8 merges rc6 information into the power group. However, when compiled with CONFIG_PM not set, modprobing i915 would taint since power_group_name is defined as NULL. This patch makes these rc6 in sysfs functions conditional upon the definition of the CONFIG_PM macro to avoid the above-mentioned problem.

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().

2012-07-27drm/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.

git://people.freedesktop.org/~danvet/drm-intel into drm-next Daniel writes: (this pull is the one with the bad patch dropped) First pile of fixes for 3.6 already, and I'm afraid it's a bit larger than what I'd wish for. But I've moved all the feature-y stuff to -next, so this really is all -fixes. Most of it is handling fallout from the hw context stuff, discovered now that mesa git has started using them for real. Otherwise all just small fixes: - unbreak modeset=0 on gen6+ (regressed in next) - const mismatch fix for ->mode_fixup - simplify overly clever lvds modeset code (current code can totally confuse backlights, resulting in broken panels until a full power draw restores them). - fix some fallout from the flushing_list disabling (regression only introduced in -next) - DP link train improvements (this also kills the last 3.2 dp regression afaik) - bugfix for the new ddc VGA detection on newer platforms - minor backlight fixes (one of them a -next regression) - only enable the required PM interrupts (to avoid waking up the cpu unnecessarily) - some really minor bits (workaround clarification, make coverty happy, hsw init fix) * 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel: (23 commits) drm/i915: unbreak lastclose for failed driver init drm/i915: Set the context before setting up regs for the context. drm/i915: constify mode in crtc_mode_fixup drm/i915/lvds: ditch ->prepare special case drm/i915: dereferencing an error pointer drm/i915: fix invalid reference handling of the default ctx obj drm/i915: Add -EIO to the list of known errors for __wait_seqno drm/i915: Flush the context object from the CPU caches upon switching drm/i915: Make the lock for pageflips interruptible drm/i915: don't forget the PCH backlight registers drm/i915: Insert a flush between batches if the breadcrumb was dropped drm/i915: missing error case in init status page drm/i915: mask tiled bit when updating ILK sprites drm/i915: try to train DP even harder drm/i915: kill intel_ddc_probe drm/i915: check whether we actually received an edid in detect_ddc drm/i915: fix up PCH backlight #define mixup drm/i915: Add comments to explain the BSD tail write workaround drm/i915: Disable the BLT on pre-production SNB hardware drm/i915: initialize power wells in modeset_init_hw ...
