Revert "drm/i915: fix infinite loop at gen6_update_ring_freq"
This reverts commit
4b28a1f3ef55a3b0b68dbab1fe6dbaf18e186710.
This patch duct-tapes over some issue in the current bdw rps patches
which must wait with enabling rc6/rps until the very first batch has
been submitted by userspace.
But those patches aren't merged yet, and for upstream we need to have
an in-kernel emission of the very first batch. I shouldn't have
merged this patch so let's revert it again.
Also Imre noticed that even when rps is set up normally there's a
small window (due to the 1s delay of the async rps init work) where we
could runtime suspend already and blow up all over the place. Imre has
a proper fix to block runtime pm until the rps init work has
successfully completed.

without requiring a great deal of review to make sure the shrinker path

Theoretically (by design) the shrinker can end up destroying a context,
which enforces the reasoning for doing the fix this way instead of
moving the reference to later in the function.

drm/i915: move power domain init earlier during system resume
During resume the intel hda audio driver depends on the i915 driver
reinitializing the audio power domain. Since the order of calling the
i915 resume handler wrt. that of the audio driver is not guaranteed,
move the power domain reinitialization step to the resume_early
handler. This is guaranteed to run before the resume handler of any
other driver.
The power domain initialization in turn requires us to enable the i915
pci device first, so move that part earlier too.
Accordingly disabling of the i915 pci device should happen after the
audio suspend handler ran. So move the disabling later from the i915
resume handler to the resume_late handler.
v2:
- move intel_uncore_sanitize/early_sanitize earlier too, so they don't
get reordered wrt. intel_power_domains_init_hw()

Clients like i915 need to segregate cache domains within the GTT which
can lead to small amounts of fragmentation. By allocating the uncached
buffers from the bottom and the cacheable buffers from the top, we can
reduce the amount of wasted space and also optimize allocation of the
mappable portion of the GTT to only those buffers that require CPU
access through the GTT.
For other drivers, allocating small bos from one end and large ones
from the other helps improve the quality of fragmentation.

drm/i915: Move all ring resets before setting the HWS page

drm/i915: disable rings before HW status page setup
we reordered stopping the rings to do so before we set the HWS register.
However, there is an extra workaround for g45 to reset the rings twice,
and for consistency we should apply that workaround before setting the
HWS to be sure that the rings are truly stopped.

drm/i915: possibly invalidate TLB before context switch
The original commit attempted to only invalidate when necessary
(very much a relic from the old days). Now, we can just always invalidate.
I guess the old TODO still exists. Since we seem to have abandoned ILK
contexts however, there isn't much point in even remembering.
