drm/amd/display: Support vertical interrupt 0 for all dcn ASIC

2022-07-20T20:04:11Z

[Why] When CONFIG_DRM_AMD_SECURE_DISPLAY is enabled, it will try to register vertical interrupt 0 for specific task. Currently, only dcn10 have defined relevant info for vertical interrupt 0. If we enable CONFIG_DRM_AMD_SECURE_DISPLAY for other dcn ASIC, will get DC_IRQ_SOURCE_INVALID while calling dc_interrupt_to_irq_source() and cause pointer errors. [How] Add support of vertical interrupt 0 for all dcn ASIC. Tested-by: Daniel Wheeler Acked-by: Alan Liu Signed-off-by: Wayne Lin Signed-off-by: Alex Deucher

drm/amd/display: remove redundant CONFIG_DRM_AMD_DC_DCN in irq

2022-05-10T21:53:13Z

[Why & How] CONFIG_DRM_AMD_DC_DCN is used by pass the compilation failures, but DC code should be OS-agnostic. This patch fixes it by removing unnecessasry CONFIG_DRM_AMD_DC_DCN in irq directory.

drm/amd/display: Turn global functions into static functions

drm/amd/display: Log DMCUB trace buffer events

2021-04-09T20:40:43Z

[Why] We want to log DMCUB trace buffer events as Linux kernel traces. [How] Register an IRQ handler for DMCUB outbox0 interrupt in amdgpu_dm, and log the messages in the DMCUB tracebuffer to a new DMCUB TRACE_EVENT as soon as we receive the outbox0 IRQ from DMCUB FW.

drm/amd/display: Use VUPDATE_NO_LOCK instead of VUPDATE for dcn30

2020-07-10T21:41:12Z

[Why] Soft hangs occur when FreeSync is engaged since we utilize VUPDATE (which doesn't fire when holding the pipe lock) to send back vblank events when FreeSync is active. [How] The alternative (working) interrupt source for this mechanism is VUPDATE_NO_LOCK. We already use this all other DCN revisions so align dcn30 with those as well.
