2019-11-19drm/amd/display: Use a temporary copy of the current state when updating DSC ↵Nikola Cornij1-7/+24
config [why] When updating DSC config, a new config has to be validated before proceeding with applying the update. Validation, however, modifies the current state. This means DSC config validation would affect pipe re-assignment, causing intermittent screen corruption issues when ODM is required for DSC. [how] - Use a copy of the current state for modified DSC config validation - Set the update type to FULL_UPDATE to correctly validate and set the actual state used for committing the streams Signed-off-by: Nikola Cornij <nikola.cornij@amd.com> Reviewed-by: Dmytro Laktyushkin <Dmytro.Laktyushkin@amd.com> Acked-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
2019-11-19drm/amd/display: Spin for DMCUB PHY init in DCNicholas Kazlauskas1-4/+17
[Why] DCN will hang if we access registers before PHY init is done. So we need to spin or abort. [How] On hardware with DMCUB running and working we shouldn't time out waiting for this to finish and we shouldn't hit the spin cycle. If there's no hardware support then we should exit out of the function early assuming that PHY init was already done elsewhere. If we hit the timeout then there's likely a bug in firmware or software and we need to debug - add errors and asserts as appropriate.

2019-11-13drm/amd/display: Disable VUpdate interrupt for DCN hardwareLeo Li1-28/+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.

2019-11-13drm/amd/display: Send vblank and user events at vsartup for DCNLeo Li1-1/+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.

2019-11-13drm/amd/display: use previous aux timeout val if no repeater.abdoulaye berthe6-22/+52
[Why] The aux timeout value is not default before reading link cap. Setting it to default when lttpr is not enabled causes some monitor not to light up. [How] Read the aux engine timeout value before setting it to extended. Set the aux engine timeout to its previous value if no lttpr.
