Our low-level wait routine has evolved from our generic wait interface
that handled unlocked, RPS boosting, waits with time tracking. If we
push our GEM fence tracking to use reservation_objects (required for
handling multiple timelines), we lose the ability to pass the required
information down to i915_wait_request(). However, if we push the extra
functionality from i915_wait_request() to the individual callsites
(i915_gem_object_wait_rendering and i915_gem_wait_ioctl) that make use
of those extras, we can both simplify our low level wait and prepare for
extending the GEM interface for use of reservation_objects.

We are not allowed to touch the GTT entries underneath an atomic section,
as they take a rpm wakelock (which is illegal from atomic context) and
in the near future acquiring the DMA address for a page within an object
may sleep for an allocation. This makes the current shortcircuit in
relocation_iomap() for performing a second relocation on an adjacent page
illegal, and we need to release the atomic iomapping, lookup the DMA,
insert it into the GTT before reentering the atomic iomap section.
As it happens, this is precisely what we do on if we are using an
iomapping over the full object and not just a single page and by
removing the shortcut, we do the right thing.

drm/i915/lspcon: Add workaround for resuming in PCON mode
On my APL the LSPCON firmware resumes in PCON mode as opposed to the
expected LS mode. It also appears to be in a state where AUX DPCD reads
will succeed but return garbage recovering only after a few hundreds of
milliseconds. After the recovery time DPCD reads will result in the
correct values and things will continue to work. If I2C over AUX is
attempted during this recovery time (implying an AUX write transaction)
the firmware won't recover and will stay in this broken state.
As a workaround check if the firmware is in PCON state after resume and
if so wait until the correct DPCD values are returned. For this we
compare the branch descriptor with the one we cached during init time.
If the firmware was in the LS state, we skip the w/a and continue as
before.

drm/i915/guc: WA to address the Ringbuffer coherency issue
Driver accesses the ringbuffer pages, via GMADR BAR, if the pages are
pinned in mappable aperture portion of GGTT and for ringbuffer pages
allocated from Stolen memory, access can only be done through GMADR BAR.
In case of GuC based submission, updates done in ringbuffer via GMADR
may not get committed to memory by the time the Command streamer starts
reading them, resulting in fetching of stale data.
For Host based submission, such problem is not there as the write to Ring
Tail or ELSP register happens from the Host side prior to submission.
Access to any GFX register from CPU side goes to GTTMMADR BAR and Hw already
enforces the ordering between outstanding GMADR writes & new GTTMADR access.
MMIO writes from GuC side do not go to GTTMMADR BAR as GuC communication to
registers within GT is contained within GT, so ordering is not enforced
resulting in a race, which can manifest in form of a hang.
To ensure the flush of in-flight GMADR writes, a POSTING READ is done to
GuC register prior to doorbell ring.
There is already a similar WA in i915_gem_object_flush_gtt_write_domain(),
which takes care of GMADR writes from User space to GEM buffers, but not the
ringbuffer writes from KMD.
This WA is needed on all recent HW.
v2:
- Use POSTING_READ_FW instead of POSTING_READ as GuC register do not lie
in any forcewake domain range and so the overhead of spinlock & search
in the forcewake table is avoidable. (Chris)

drm/radeon/pm: autoswitch power state when in balanced mode
The current default of always using the performance power state leads
to increased power consumption of mobile devices, which have a dedicated
battery power state. Switch between the performance and battery power
state automatically, dpending on the current AC power status, when the
user asked for the balanced power state.
The user can still override this logic by asking for the performance
or battery power state explicitly.
