We already request max freq in the load path, moving it to __xe_guc_upload will ensure this speeds up GuC load in the resume path as well. v2: Rename xe_guc_pc_init_early since we now call it per GuC load (Michal W) v3: Keep pc_init_early() and init RPx values there (Rodrigo) Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Vinay Belgaumkar <vinay.belgaumkar@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240620224928.3986377-3-vinay.belgaumkar@intel.com Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
