drm/amd/display: Move FPU associated DCN30 code to DML folder

2022-05-26T18:56:31Z

[why & how] As part of the FPU isolation work documented in https://patchwork.freedesktop.org/series/93042/, isolate code that uses FPU in DCN30 to DML, where all FPU code should locate.

drm/amdgpu/display: Remove t_srx_delay_us.

2022-01-25T22:54:23Z

Unused. Convert the divisions into asserts on the divisor, to debug why it is zero. The divide by zero is suspected of causing kernel panics. While I have no idea where the zero is coming from I think this patch is a positive either way.

drm/amd/display: Fix rest of pass-by-value structs in DML

drm/amd/display: Pass display_pipe_params_st as const in DML

2021-09-23T19:17:29Z

[Why] This neither needs to be on the stack nor passed by value to each function call. In fact, when building with clang it seems to break the Linux's default 1024 byte stack frame limit. [How] We can simply pass this as a const pointer.

drm/amd/display: Move AllowDRAMSelfRefreshOrDRAMClockChangeInVblank to bounding box

2021-08-26T17:57:33Z

[Why] This is a global parameter, not a per pipe parameter and it's useful for experimenting with the prefetch schedule to be adjustable from the SOC bb. [How] Add a parameter to the SOC bb, default is the existing policy for all DCN. Fill it in when filling SOC bb parameters. Revert the policy to use MinDCFClk at the same time since that's not going to give us P-State in most cases on the spreadsheet.
