Subject: [PATCH 4/6] arm64: dts: qcom: sm8750: Add GPU cooling
Date: Sun, 09 Aug 2026 01:53:11 +0530 [thread overview]
Message-ID: <20260809-pakala-gpu-v1-4-207ad1fac1c7@oss.qualcomm.com> (raw)
In-Reply-To: <20260809-pakala-gpu-v1-0-207ad1fac1c7@oss.qualcomm.com>
From: Gaurav Kohli <gaurav.kohli@oss.qualcomm.com>
Unlike the CPU, the GPU does not throttle its speed automatically
when it reaches high temperatures.
Set up GPU cooling by throttling the GPU speed
when reaching 105°C.
