Subject: [PATCH 9/9] arm64: tegra: Hook up VPR to the GPU
Date: Tue, 2 Sep 2025 17:46:29 +0200 [thread overview]
Message-ID: <20250902154630.4032984-10-thierry.reding@gmail.com> (raw)
In-Reply-To: <20250902154630.4032984-1-thierry.reding@gmail.com>
From: Thierry Reding <treding@nvidia.com>
The GPU needs to be idled before the VPR can be resized and unidled
afterwards. Associate it with the VPR using the standard memory-region
device tree property.
