| * drm/amd/display: Disable VUpdate interrupt for DCN hardwareLeo Li2019-11-131-28/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Why] On DCN hardware, the crtc_high_irq handler makes vupdate_high_irq handler redundant. All the vupdate handler does is handle vblank events, and update vrr for DCE hw (excluding VEGA, more on that later). As far as usermode is concerned. vstartup happens close enough to vupdate on DCN that it can be considered the "same". Handling vblank and updating vrr at vstartup effectively replaces vupdate on DCN. Vega is a bit special. Like DCN, the VRR registers on Vega are double-buffered, and swapped at vupdate. But Unlike DCN, it lacks a vstartup interrupt. This means we can't quite remove the vupdate handler for it, since delayed user events due to vrr are sent off there. [How] Remove registration of vupdate interrupt handler for DCN. Disable vupdate interrupt if asic family DCN, enable otherwise.

| * drm/amd/display: Send vblank and user events at vsartup for DCNLeo Li2019-11-131-1/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Why] For DCN hardware, the crtc_high_irq handler is assigned to the vstartup interrupt. This is different from DCE, which has it assigned to vblank start. We'd like to send vblank and user events at vstartup because: * It happens close enough to vupdate - the point of no return for HW. * It is programmed as lines relative to vblank end - i.e. it is not in the variable portion when VRR is enabled. We should signal user events here. * The pflip interrupt responsible for sending user events today only fires if the DCH HUBP component is not clock gated. In situations where planes are disabled - but the CRTC is enabled - user events won't be sent out, leading to flip done timeouts. Consequently, this makes vupdate on DCN hardware redundant. It will be removed in the next change. [How] Add a DCN-specific crtc_high_irq handler, and hook it to the VStartup signal. Inside the DCN handler, we send off user events if the pflip handler hasn't already done so.

Pointer points to the current dm_connector_state. v6: - Remove new param from stream v7: - Fix error with using max capable bpc v8: - squash in fix from Gustavo A. R.
