2020-05-28drm/amd/display: combine public interfaces into single headerAnthony Koo1-154/+0
[Why] We want to better encapsulate all driver-fw dependencies into a single file. [How] Combine all the headers under inc folder into a single header Signed-off-by: Anthony Koo <Anthony.Koo@amd.com> Reviewed-by: Tony Cheng <Tony.Cheng@amd.com> Acked-by: Qingqing Zhuo <qingqing.zhuo@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2020-04-28drm/amd/display: Pass command instead of header into DMUB serviceNicholas Kazlauskas1-4/+2
[Why] We read memory that we shouldn't be touching if the struct isn't a full union dmub_rb_cmd. [How] Fix up all the callers and functions that take in the dmub_cmd_header to use the dmub_rb_cmd instead.

2020-01-16drm/amd/display: Flush framebuffer data before passing to DMCUBNicholas Kazlauskas1-0/+17
[Why] There's a data race that can occur between when we update the inbox write pointer vs when the memory for the command actually gets flushed from the map to the framebuffer. DMCUB can read stale or partially invalid data when this race occurs. [How] Before updating the write pointer we can read back all pending commands to ensure that we stall for the writes to be flushed to framebuffer. We don't need to worry about choosing HDP vs VM flush with this mechanism. Drop the dmub_srv_cmd_submit() while we're updating this to work correctly since nothing was actually using this API and the caller should be explicit about the API flow here - by doing this on execute we can give some extra time for the flush to finish while preparing other commands. We should try to avoid writing single commands because of this overhead.

2019-11-13drm/amd/display: Add the DMUB serviceNicholas Kazlauskas1-0/+129
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.
