[Why] We need DMCUB on Renoir to support DMCU and PHY initialization. The DMUB service provides a mechanism to load the DMCUB. [How] Include the DMUB service in amdgpu_dm. Frontdoor loading of the DMCUB firmware needs to happen via PSP. To pass the firmware to PSP we need to hand it off to the firmware list in the base driver during software initialization. Most of the DMUB service can technically be initialized at this point in time, but we don't want to be allocating framebuffer memory for hardware that doesn't support the DMCUB and in order to check that we need to be able to read registers - something DM helpers aren't setup to do in software initialization. So everything but the service creation itself will get deferred to hardware initialization. Signed-off-by:

[Why] PSP version format is AB.CD.EF.GH, where CD and GH is the main version. current psp version check for dmcub loading dmcu check 0x00110029, in case of some psp version eg: 0x00110227 which main version should be 0x00110027, will result in unexpeceted dmcub loading dmcu FW. [How] Add psp version mask 0x00FF00FF for checking version. Signed-off-by:

The DMUB service is the interface to the DMCUB. It's required to support Renoir features so it will be enabled and compiled automatically when the Renoir display engine is enabled via CONFIG_DRM_AMD_DC_DCN2_1. DMUB code will initially be guarded by CONFIG_DRM_AMD_DC_DMUB and later switched to CONFIG_DRM_AMD_DC_DCN2_1 with the config option dropped. Signed-off-by:

The interface to the DMCUB won't be through DC itself. DC will instead call into the DMUB interface introduced with a future change. The CONFIG_DRM_AMD_DC_DMUB defines will still be used for now but will be dropped at the end of the series. Since this define was never configurable in the first place this code wasn't used.

DMCUB ucode requires secure loading through PSP. This is already supported in PSP as GFX_FW_TYPE_DMUB, it just needs to be mapped from AMDGPU_UCODE_ID_DMCUB to GFX_FW_TYPE_DMUB. DMUB is a shorthand name for DMCUB and can be used interchangeably. Signed-off-by:

[Why] On Navi10, and presumably arcterus, updating pp_table via sysfs would not re-scale the maximum possible power limit one can set. On navi10, the SMU code ignored the power percentage overdrive setting entirely, and would not allow you to exceed the default power limit at all. [How] Adding a function to the SMU interface to get the pptable version of the default power limit allows ASIC-specific code to provide the correct maximum-settable power limit for the current pptable. v3: fix spelling (Alex) Reviewed-by:

xgmi, ras, hdcp and dtm ta are actually separated ucode and need to handled case by case to upload to psp. We support the case that ta binary have one or multiple of them built-in. As a result, the driver should check each ta binariy's availablity before decide to upload them to psp. In the terminate (unload) case, the driver will check the context readiness before perform unload activity. It's fine to keep it as is. Signed-off-by:
