[Why & How] In some cases, there are calls to transition from TX_ON to TX_ON. This is expected, so do not assert. However, these are redundant, so return prematurely. Reviewed-by:

[Why] DIG_FIFO_ERROR = 1 caused mst daisy chain 2nd monitor black. [How] We need to set dig fifo read start level = 7 before dig fifo reset during dig fifo enable according to hardware designer's suggestion. If it is zero, it will cause underflow or overflow and DIG_FIFO_ERROR = 1. Reviewed-by:

[Why] In amdgpu_cs_ioctl, amdgpu_job_free could be performed ealier if there is -ERESTARTSYS error. In this case, job->hw_fence could be not initialized yet. Putting hw_fence during amdgpu_job_free could lead to a use-after-free warning. [How] Check if drm_sched_job_init is performed before job_free by checking s_fence. v2: Check hw_fence.ops instead since it could be NULL if fence is not initialized. Reverse the condition since !=NULL check is discouraged in kernel. Signed-off-by:

[Why] Each index in the DPSTREAMCLK_CNTL register phyiscally maps 1-to-1 with HPO stream encoder instance. On the other hand, each index in DTBCLK_P_CNTL physically maps 1-to-1 with OTG instance. Current DCN32 DPSTREAMCLK_CLK programing assumes that OTG instance always maps 1-to-1 with HPO stream encoder instance. This is not always guaranteed and can result in blackscreen. [How] Program the correct dpstreamclk instance with the correct dtbclk_p source. Reviewed-by:

According to the ACPI specification [1], the ACPI_FADT_LOW_POWER_S0 flag merely means that it is better to use low-power S0 idle on the given platform than S3 (provided that the latter is supported) and it doesn't preclude using either of them (which of them will be used depends on the choices made by user space). However, on some systems that flag is used to indicate whether or not to enable special firmware mechanics allowing the system to save more energy when suspended to idle. If that flag is unset, doing so is generally risky. Accordingly, add a comment to explain the ACPI_FADT_LOW_POWER_S0 check in amdgpu_acpi_is_s0ix_active(), the purpose of which is otherwise somewhat unclear.

[WHY] Reprogramming the stream despite no changes in ODM combine mode. Reprogramming the stream would cause intermittent black screen on display which could only be recovered through enable/disable sequence. [HOW] Fixed bug where we detected a change in ODM combine mode despite ODM combine mode being disabled. Also removed code which required stream to be reprogrammed once a change in ODM combine mode was noticed. Lastly we do not support dynamic ODM switching for HDMI TMDS and FRL on DCN32, therefore we never want to change its ODM policy. Reviewed-by:
