c4de7b0ffd drm/i915: Implement w/a for sporadic read failures on waking from rc6
As a w/a to prevent reads sporadically returning 0, we need to wait for
the GT thread to return to TC0 before proceeding to read the registers.

v2: adapt for Haswell changes (Eugeni).

v3: use wait_for_atomic_us for thread status polling.

v3: *really* use wait_for_atomic for polling.

97f209bcfc drm/i915: "Flush Me Harder" required on gen6+
The prep to remove the flushing list in

commit cc889e0f6c
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Wed Jun 13 20:45:19 2012 +0200

    drm/i915: disable flushing_list/gpu_write_list

causes quite some decent regressions. We can fix this by setting the
CS_STALL bit to ensure that the following seqno write happens only
after the cache flush has completed. But only do that when the caller
actually wants the flush (and not also when we invalidate caches
before starting the next batch).

I've looked through all our ancient scrolls about gen6+ pipe control
workarounds, and this seems to be indeed a legal combination: We're
allowed to set the CS_STALL bit when we flush the render cache (which
we do).

While yelling at this code, also pass back the return value from
intel_emit_post_sync_nonzero_flush properly.

v2: Instead of emitting more pipe controls, set the CS_STALL bit on
the write flush as suggested by Chris Wilson. It seems to work, too.

a8b0bbabf7 drm/i915/sprite: Fix mem leak in intel_plane_init()
If we ever hit the default case in the switch statement we'll return
from the function without freeing the memory we just allocated to
'intel_plane' (but that has not been used).

This patch gets rid of the leak by freeing the memory just before we
return.

01a06850fb drm/i915: disable drm agp support for !gen3 with kms enabled
This is the quick&dirty way Dave Airlie suggested to workaround the
midlayer drm agp brain-damange. Note that i915_probe is only called
when the driver has ksm enabled, so no need to check for that.

We also need to move the intel_agp_enabled check at the right place.
Note that the only thing this does is enforce the correct module load
order (by using a symbol from intel-agp.ko) to ensure that the fake
agp driver is ready before the drm core tries to set up the agp stuff.

v2: Add a comment to explain why gen3 needs all this legacy fake agp
stuff - we've shipped an XvMC library with a kms-enabled ddx that
requires it (but only on gen3).

v3: Make it clear that this is only a gen3 issue in the comment.

79f5b2c759 drm/i915: make enable/disable_gt_powersave locking consistent
The enable functions grabbed dev->struct_mutex themselves, whereas
the disable functions expected dev->struct_mutex to be held by the
caller. Move the locking out to the (currently only) callsite of
intel_enable_gt_powersave to make this more consistent.

Originally this was prep work for future patches, but I've chased down
a totally wrong alley. Still, I think this is a sensible
clarification.

Merge tag 'v3.5-rc4' into drm-intel-next-queued

I want to merge the "no more fake agp on gen6+" patches into
drm-intel-next (well, the last pieces). But a patch in 3.5-rc4 also
adds a new use of dev->agp. Hence the backmarge to sort this out, for
otherwise drm-intel-next merged into Linus' tree would conflict in the
relevant code, things would compile but nicely OOPS at driver load :(

Conflicts in this merge are just simple cases of "both branches
changed/added lines at the same place". The only tricky part is to
keep the order correct wrt the unwind code in case of errors in
intel_ringbuffer.c (and the MI_DISPLAY_FLIP #defines in i915_reg.h
together, obviously).

Conflicts:
	drivers/gpu/drm/i915/i915_reg.h
	drivers/gpu/drm/i915/intel_ringbuffer.c

And restructure the IRQ handling a little.  We can use pipestat for most
things, and make sure we don't affect pipe events when enabling and
disabling vblank interupts.

We can leave vblank interrupts masked but enabled so we're not dependent
on the first client to toggle the disable timer.  We can also mask all
render based interrupts, since the ring code will handle unmasking them
for us.

e87c46993e agp/intel: allow cacheable and GDFT PTEs on ValleyView
The PTE format is similar to SNB, but we don't support an MLC and don't
need chipset flushing.

Note: I have my questions whether this is right, given that MLC died
for snb & ivb, that ivb has grown a L3$ cache instead (which vlv seems
to have, too) and that the LLC bit here isn't actually LLC, but just
means 'snoop cpu caches'.

But I plan to burn this all with the heat of a thousands suns in my
gtt rework, so who cares ;-)

cc889e0f6c drm/i915: disable flushing_list/gpu_write_list
This is just the minimal patch to disable all this code so that we can
do decent amounts of QA before we rip it all out.

The complicating thing is that we need to flush the gpu caches after
the batchbuffer is emitted. Which is past the point of no return where
execbuffer can't fail any more (otherwise we risk submitting the same
batch multiple times).

Hence we need to add a flag to track whether any caches associated
with that ring are dirty. And emit the flush in add_request if that's
the case.

Note that this has a quite a few behaviour changes:
- Caches get flushed/invalidated unconditionally.
- Invalidation now happens after potential inter-ring sync.

I've bantered around a bit with Chris on irc whether this fixes
anything, and it might or might not. The only thing clear is that with
these changes it's much easier to reason about correctness.

Also rip out a lone get_next_request_seqno in the execbuffer
retire_commands function. I've dug around and I couldn't figure out
why that is still there, with the outstanding lazy request stuff it
shouldn't be necessary.

v2: Chris Wilson complained that I also invalidate the read caches
when flushing after a batchbuffer. Now optimized.

v3: Added some comments to explain the new flushing behaviour.
