2019-10-03drm/amdgpu: Iterate through DRM connectors correctlyLyude Paul1-2/+8
Currently, every single piece of code in amdgpu that loops through connectors does it incorrectly and doesn't use the proper list iteration helpers, drm_connector_list_iter_begin() and drm_connector_list_iter_end(). Yeesh. So, do that.

2019-04-03drm/amd/display: In VRR mode, do DRM core vblank handling at end of vblank. (v2)Mario Kleiner1-0/+22
In VRR mode, proper vblank/pageflip timestamps can only be computed after the display scanout position has left front-porch. Therefore delay calls to drm_crtc_handle_vblank(), and thereby calls to drm_update_vblank_count() and pageflip event delivery, to after the end of front-porch when in VRR mode. We add a new vupdate irq, which triggers at the end of the vupdate interval, ie. at the end of vblank, and calls the core vblank handler function. The new irq handler is not executed in standard non-VRR mode, so vblank handling for fixed refresh rate mode is identical to the past implementation. v2: Implement feedback by Nicholas and Paul Menzel.
