Subject: [Intel-gfx] [PATCH 09/14] drm/i915/guc/slpc: Add debugfs for SLPC info
Date: Wed, 21 Jul 2021 09:11:15 -0700 [thread overview]
Message-ID: <20210721161120.24610-10-vinay.belgaumkar@intel.com> (raw)
In-Reply-To: <20210721161120.24610-1-vinay.belgaumkar@intel.com>
This prints out relevant SLPC info from the SLPC shared structure.
We will send a h2g message which forces SLPC to update the
shared data structure with latest information before reading it.
v2: Address review comments (Michal W)
