2020-04-28drm/amdgpu: Fix per-IB secure flag GFX hangHuang Rui
Since commit "Move to a per-IB secure flag (TMZ)", we've been seeing hangs in GFX. We need to send FRAME CONTROL stop/start back-to-back, every time we flip the TMZ flag. That is, when we transition from TMZ to non-TMZ we have to send a stop with TMZ followed by a start with non-TMZ, and similarly for transitioning from non-TMZ into TMZ. This patch implements this, thus fixing the GFX hang. v1 -> v2: As suggested by Luben, and accept part of implemetation from this patch: - Put "secure" closed to the loop and use optimization - Change "secure" to bool again, and move "secure == -1" out of loop. v3: Small fixes/optimizations.

2020-04-28drm/amd/display: Defer cursor update around VUPDATE for all ASICNicholas Kazlauskas
[Why] Fixes the following scenario: - Flip has been prepared sometime during the frame, update pending - Cursor update happens right when VUPDATE would happen - OPTC lock acquired, VUPDATE is blocked until next frame - Flip is delayed potentially infinitely With the igt@kms_cursor_legacy cursor-vs-flip-legacy test we can observe nearly *13* frames of delay for some flips on Navi. [How] Apply the Raven workaround generically. When close enough to VUPDATE block cursor updates from occurring from the dc_stream_set_cursor_* helpers. This could perhaps be a little smarter by checking if there were pending updates or flips earlier in the frame on the HUBP side before applying the delay, but this should be fine for now.
