Subject: [PATCH v3 06/20] gpu: host1x: Cleanup and refcounting for syncpoints
Date: Wed, 7 Oct 2020 20:12:24 +0300 [thread overview]
Message-ID: <20201007171238.1795964-7-mperttunen@nvidia.com> (raw)
In-Reply-To: <20201007171238.1795964-1-mperttunen@nvidia.com>
Add reference counting for allocated syncpoints to allow keeping
them allocated while jobs are referencing them. Additionally,
clean up various places using syncpoint IDs to use host1x_syncpt
pointers instead.
Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com>
