[Why] When trying to lightup two 4k60 non-DSC displays behind a branch device that supports DSC we can't lightup both at once due to bandwidth limitations - each requires 48 VCPI slots but we only have 63. [How] The workaround already exists in the code but is guarded by a CONFIG that cannot be set by the user and shouldn't need to be. Check for specific branch device IDs to device whether to enable the workaround for multiple display scenarios. Reviewed-by:

IH ring1 is used to process GPU retry fault, overflow is enabled to drain retry fault because we want receive other interrupts while handling retry fault to recover range. There is no overflow flag set when wptr pass rptr. Use timestamp of rptr and wptr to handle overflow and drain retry fault. If fault timestamp goes backward, the fault is filtered and should not be processed. Drain fault is finished if processed_timestamp is equal to or larger than checkpoint timestamp. Add amdgpu_ih_functions interface decode_iv_ts for different chips to get timestamp from IV entry with different iv size and timestamp offset. amdgpu_ih_decode_iv_ts_helper is used for vega10, vega20, navi10.

[Why] PSR currently relies on the kernel's delayed vblank on/off mechanism as an implicit bufferring mechanism to prevent excessive entry/exit. Without this delay the user experience is impacted since it can take a few frames to enter/exit. [How] Only allow vblank disable immediate for DC when psr is not supported. Leave a TODO indicating that this support should be extended in the future to delay independent of the vblank interrupt.

If xnack is on, VM retry fault interrupt send to IH ring1, and ring1 will be full quickly. IH cannot receive other interrupts, this causes deadlock if migrating buffer using sdma and waiting for sdma done while handling retry fault. Remove VMC from IH storm client, enable ring1 write pointer overflow, then IH will drop retry fault interrupts and be able to receive other interrupts while driver is handling retry fault. IH ring1 write pointer doesn't writeback to memory by IH, and ring1 write pointer recorded by self-irq is not updated, so always read the latest ring1 write pointer from register. Signed-off-by:
