Subject: [PATCH v3 11/20] gpu: host1x: Add job release callback
Date: Wed, 7 Oct 2020 20:12:29 +0300 [thread overview]
Message-ID: <20201007171238.1795964-12-mperttunen@nvidia.com> (raw)
In-Reply-To: <20201007171238.1795964-1-mperttunen@nvidia.com>
Add a callback field to the job structure, to be called just before
the job is to be freed. This allows the job's submitter to clean
up any of its own state, like decrement runtime PM refcounts.
