[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. Reviewed-by:

[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. Reviewed-by:

[Why] It is confusing to sinks if we send VSC SDP only on some format. Today we signal colorimetry format using MSA while in formats like sRGB. But when we switch to BT2020 we set the bit to ignore MSA colorimetry and instead use the colorimetry information in the VSC SDP. But if sink supports signaling of colorimetry via VSC SDP we should always set the MSA MISC1 bit 6, instead of doing so selectively. [How] If sink supports signaling of colorimetry via VSC SDP, and we are sending the colorimetry info via VSC SDP with packet revision 05h, then always set MSA MISC1 bit 6. Signed-off-by:

[Why] We need DMCUB on Renoir to support DMCU and PHY initialization. The DMUB service provides a mechanism to load the DMCUB. [How] Include the DMUB service in amdgpu_dm. Frontdoor loading of the DMCUB firmware needs to happen via PSP. To pass the firmware to PSP we need to hand it off to the firmware list in the base driver during software initialization. Most of the DMUB service can technically be initialized at this point in time, but we don't want to be allocating framebuffer memory for hardware that doesn't support the DMCUB and in order to check that we need to be able to read registers - something DM helpers aren't setup to do in software initialization. So everything but the service creation itself will get deferred to hardware initialization. Signed-off-by:
