Subject: [RFC PATCH 71/97] drm/i915/guc: Provide mmio list to be saved/restored on engine reset
Date: Thu, 6 May 2021 12:14:25 -0700 [thread overview]
Message-ID: <20210506191451.77768-72-matthew.brost@intel.com> (raw)
In-Reply-To: <20210506191451.77768-1-matthew.brost@intel.com>
From: John Harrison <John.C.Harrison@Intel.com>
The driver must provide GuC with a list of mmio registers
that should be saved/restored during a GuC-based engine reset.
Unfortunately, the list must be dynamically allocated as its size is
variable. That means the driver must generate the list twice - once to
work out the size and a second time to actually save it.
