Subject: [PATCH v2 5/8] arm64: tegra: Add Host1x context stream IDs on Tegra186+
Date: Thu, 16 Sep 2021 17:32:59 +0300	[thread overview]
Message-ID: <20210916143302.2024933-6-mperttunen@nvidia.com> (raw)
In-Reply-To: <20210916143302.2024933-1-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.

v2:
* Added context devices on T194.
* Use iommu-map instead of custom property.
