- Add is_drr parameter to indicate DRR is enabled on the panel to determine whether SubVP MCLK switch logic should be enabled - Add DRR manual trigger in FW (instead of driver) because manual trigger programming triggers DRR update pending and can block SubVP MCLK switches from taking place Acked-by:

[Why] Access violation occurs when swapping between HDMI and FRL monitors because we're missing the immediate_disable_crtc callback and it's required for the DCN314 clk manager.

Nicholas Kazlauskas authored
[Why] We don't write out attributes after disabling and re-enabling the link on some monitors, causing some, but not all, HDMI displays to fail to lightup on DCN314. [How] Firmware used to do this after DIG link setup. Since firmware is no longer doing this to support USB4 and dynamic link remapping we'll need to add this to driver in the equivalent paths. New optional callbacks were created in the stream encoder interface and implementations were added for DCN314. Reviewed-by:

If process has signal pending, mmu_notifier_get_locked fails and calls ops->free_notifier, kfd_process_free_notifier will schedule kfd_process_wq_release as process refcount is 1, but process structure is already freed. This use after free bug causes system crash with different backtrace. The fix is to increase process refcount and then decrease the refcount after mmu_notifier_get success. Signed-off-by:
