Subject: [RFC PATCH 6/8] arm64: tegra: Add Host1x context stream IDs on Tegra186+
Date: Mon, 8 Feb 2021 18:38:46 +0200 [thread overview]
Message-ID: <20210208163848.2504291-7-mperttunen@nvidia.com> (raw)
In-Reply-To: <20210208163848.2504291-1-mperttunen@nvidia.com>
Add Host1x context stream IDs on systems that support Host1x context
isolation. Host1x and attached engines can use these stream IDs to
allow isolation between memory used by different processes.
The specified stream IDs must match those configured by the hypervisor,
if one is present.
