Subject: [Intel-gfx] [PATCH 07/14] drm/i915/guc/slpc: Add methods to set min/max frequency
Date: Fri, 30 Jul 2021 13:21:12 -0700 [thread overview]
Message-ID: <20210730202119.23810-8-vinay.belgaumkar@intel.com> (raw)
In-Reply-To: <20210730202119.23810-1-vinay.belgaumkar@intel.com>
Add param set h2g helpers to set the min and max frequencies
for use by SLPC.
v2: Address review comments (Michal W)
v3: Check for positive error code (Michal W)
v4: Print generic error in set_param (Michal W)
