2017-04-04drm: Pass CRTC ID in userspace vblank eventsAnder Conselvan de Oliveira
With the atomic API, it is possible that a single commit affects multiple crtcs. If the user requests an event with that commit, one event will be sent for each CRTC, but it is not possible to distinguish which crtc an event is for in user space. To solve this, the reserved field in struct drm_vblank_event is repurposed to include the crtc_id which the event is for. The DRM_CAP_CRTC_IN_VBLANK_EVENT is added to allow userspace to query if the crtc field will be set properly.

2017-04-04drm: document drm_ioctl.[hc]Daniel Vetter
Also unify/merge with the existing stuff. I was a bit torn where to put this, but in the end I decided to put all the ioctl/sysfs/debugfs stuff into drm-uapi.rst. That means we have a bit a split with the other uapi related stuff used internally, like drm_file.[hc], but I think overall this makes more sense. If it's too confusing we can always add more cross-links to make it more discoverable. But the auto-sprinkling of links kernel-doc already does seems sufficient. Also for prettier docs and more cross-links, switch the internal defines over to an enum, as usual. v2: Update kerneldoc fro drm_compat_ioctl too (caught by 0day), plus a bit more drive-by polish. v3: Fix typo, spotted by xerpi on irc (Sergi). v4: Add missing space in comment (Neil).
