8 years agodrm/i915/lspcon: Add workaround for resuming in PCON mode

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.

v2:
- Use the DP descriptor value cached in intel_dp. (Jani)
- Get to intel_dp using container_of(), instead of a cached ptr.

8 years agodrm/i915/guc: WA to address the Ringbuffer coherency issue
Akash Goel [Tue, 25 Oct 2016 16:35:23 +0000 (22:05 +0530)]
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)
