2020-06-01drm/i915: Handle very early engine initialisation failureChris Wilson
If we fail during engine setup, we may leave some engines not yet setup. During the error cleanup, we have to be careful not to try and use the uninitialise engines before discarding them.

2020-05-29drm/i915: Check for awaits on still currently executing requestsChris Wilson
With the advent of preempt-to-busy, a request may still be on the GPU as we unwind. And in the case of a unpreemptible [due to HW] request, that request will remain indefinitely on the GPU even though we have returned it back to our submission queue, and cleared the active bit. We only run the execution callbacks on transferring the request from our submission queue to the execution queue, but if this is a bonded request that the HW is waiting for, we will not submit it (as we wait for a fresh execution) even though it is still being executed. As we know that there are always preemption points between requests, we know that only the currently executing request may be still active even though we have cleared the flag. However, we do not precisely know which request is in ELSP[0] due to a delay in processing events, and furthermore we only store the last request in a context in our state tracker.

2020-05-29drm/i915: Stop using mode->private_flagsVille Syrjälä
Replace the use of mode->private_flags with a truly private bitmaks in our own crtc state. We also need a copy in the crtc itself so the vblank code can get at it. We already have scanline_offset in there for a similar reason, as well as the vblank->hwmode which is assigned via drm_calc_timestamping_constants(). Fortunately we now have a nice place for doing the crtc_state->crtc copy in intel_crtc_update_active_timings() which gets called both for modesets and init/resume readout. The one slightly iffy spot is the INHERITED flag which we want to preserve until userspace/fb_helper does the first proper commit after actually calling .detecti() on the connectors. Otherwise we don't have the full sink capabilities (audio,infoframes,etc.) when .compute_config() gets called and thus we will fail to enable those features when the first userspace commit happens. The only internal commit we do prior to that should be from intel_initial_commit() and there we can simply preserve the INHERITED flag from the readout. v2: Deal with INHERITED in sanitize_watermarks() as well CC: Sam Ravnborg <sam@ravnborg.org> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200429103904.11727-1-ville.syrjala@linux.intel.com
