Nicholas Kazlauskas authored
[Why] Color corruption can occur on bootup into a login manager that applies a non-linear gamma LUT because the LUT may not actually be powered on before writing. It's cleared on the next full pipe reprogramming as we switch to LUTB from LUTA and the pipe accessing the LUT has taken it out of light sleep mode. [How] The MPCC_OGAM_MEM_PWR_FORCE register does not force the current power mode when set to 0. It only forces when set light sleep, deep sleep or shutdown. The register to actually force power on and ignore sleep modes is MPCC_OGAM_MEM_PWR_DIS - a value of 0 will enable power requests and a value of 1 will disable them. When PWR_FORCE!=0 is combined with PWR_DIS=0 then MPCC OGAM memory is forced into the state specified by the force bits. If PWR_FORCE is 0 then it respects the mode specified by MPCC_OGAM_MEM_LOW_PWR_MODE if the RAM LUT is not in use. We set that bit to shutdown on low power, but otherwise it inherits from bootup defaults. So for the fix: 1. Update the sequence to "force" power on when needed We can use MPCC_OGAM_MEM_PWR_DIS for this to turn on the memory even when the block is in bypass and pending to be enabled for the next frame. We need this for both low power enabled or disabled. If we don't set this then we can run into issues when we first program the LUT from bootup. 2. Don't apply FORCE_SEL Once we enable power requests with DIS=0 we run into the issue of the RAM being forced into light sleep and being unusable for display output. Leave this 0 like we used to for DCN20. 3. Rely on MPCC OGAM init to determine light sleep/deep sleep MPC low power debug mode isn't enabled on any ASIC currently but we'll respect the setting determined during init if it is. Lightly tested as working with IGT tests and desktop color adjustment. 4. Change the MPC resource default for DCN30 It was interleaving the dcn20 and dcn30 versions before depending on the sequence. 5. REG_WAIT for it to be on whenever we're powering up the memory Otherwise we can write register values too early and we'll get corruption.

drm/radeon/nislands_smc.h: Replace one-element array with flexible-array member in struct NISLANDS_SMC_SWSTATE There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure.

The screen freezes completely in this case. Wrapping the function with DC_FP_START()/DC_FP_END() seems to solve the problem. This mirrors the approach used for dcn20_validate_bandwidth.
