Subject: [PATCH 4/7] drm/amd/pm: initial feature_enabled/feature_support bitmap for vangogh
Date: Fri,  8 Jan 2021 16:55:04 +0800	[thread overview]
Message-ID: <20210108085507.1164588-5-ray.huang@amd.com> (raw)
In-Reply-To: <20210108085507.1164588-1-ray.huang@amd.com>

VanGogh supports feature mask checking which exposed by smu firmware. It
has to initial at first, otherwise, all SMU_FEATURE_xxx masks are
invalid.
