2017-12-20vfio: Simplify capability helperAlex Williamson1-5/+10
The vfio_info_add_capability() helper requires the caller to pass a capability ID, which it then uses to fill in header fields, assuming hard coded versions. This makes for an awkward and rigid interface. The only thing we want this helper to do is allocate sufficient space in the caps buffer and chain this capability into the list. Reduce it to that simple task.

2017-12-20drm/fb-helper: Add drm_fb_helper_defio_init()Noralf Trønnes1-1/+53
Add helper for initializing fbdev deferred I/O. The cleanup could have happened in drm_fb_helper_fini(), but that would have required me to set fb_info->fbdefio to NULL in a couple of drivers before they call _fini() to avoid double defio cleanup. The problem is that one of those is vboxvideo which lives in Greg's staging tree. So I put the cleanup in drm_fb_helper_fbdev_teardown(), not perfect but not that bad either.

setplane_internal callers lock_all_ctx in setplane_internal may return -EINTR, and __setplane_internal could return -EDEADLK. Making more special cases for fb would make the code even harder to read, so the easiest solution is not taking over the fb refcount, and making callers responsible for dropping the ref.

When attached to the connector, the mode_valid callback will only filter the modes provided by the connector itself as part of its probe. However, it will not be doing it when the mode is provided by the userspace, which still might result in a broken configuration. In order to enforce these constraints, move our mode_valid callback to the encoder which doesn't have this behaviour.

2017-12-19drm/i915: Avoid context dereference inside execlists_submission_taskletChris Wilson2-4/+4
A lesson that has to be relearnt over and over again is that the request does not keep a reference to the context and so we cannot freely dereference the context from inside the execlists_submission_tasklet. In particular, we try to do so in the new GEM_TRACE() so convert those over to the port->context_id we keep for GEM debugging. This means the tracing now depends on DRM_I915_GEM_DEBUG.

2017-12-19drm/i915: Protect DDI port to DPLL map from theoretical race.Rodrigo Vivi1-0/+4
In case we have multiple modesets for different connectors happening in parallel we could have a race on the RMW on these shared registers. This possibility was initially raised by Paulo when reviewing commit '555e38d27317 ("drm/i915/cnl: DDI - PLL mapping")' but the original possibility comes from commit '5416d871136d ("drm/i915/skl: Set the eDP link rate on DPLL0")'. Or maybe later when atomic commits entered into picture. Apparently the discussion around this topic showed that the right solution would be on serializing the atomic commits in a way that we don't have the possibility of races here since if that parallel modeset happenings apparently many other things will be on fire. Code is there since SKL and there was no report of issue, but since we never looked back to that serialization possibility, and also we don't have an igt case for that it is better to at least protect this corner.

2017-12-19drm/i915: Add a strong mb to resetting the has-CS-interrupt bitChris Wilson1-1/+6
After a reset, the state of the CSB registers are scrubbed and not valid until a powercontext is reloaded. We only know when a powercontext has been reloaded once we see a CS-interrupt, before then we must ignore the CSB registers within the execlists_submission_tasklet. However, glk is sporadically dying with an illegal CSB pointer value (both in the HSWP and mmio) suggesting that it is running with the CS-interrupt bit set before the powercontext has been reloaded. Make sure the clearing of that bit is serialised on reset with the re-enabling of the tasklet.
