Subject: [Intel-gfx] [PATCH 21/47] drm/i915/guc: Ensure G2H response has space in buffer
Date: Thu, 24 Jun 2021 00:04:50 -0700 [thread overview]
Message-ID: <20210624070516.21893-22-matthew.brost@intel.com> (raw)
In-Reply-To: <20210624070516.21893-1-matthew.brost@intel.com>
Ensure G2H response has space in the buffer before sending H2G CTB as
the GuC can't handle any backpressure on the G2H interface.
