From: Stephan Gerhold Date: Wed, 19 Feb 2025 11:36:20 +0000 (+0100) Subject: arm64: dts: qcom: x1e80100: Add GPU cooling X-Git-Tag: v6.16-rc1~97^2~20^2~115^2~126 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5ba21fa11f473c9827f378ace8c9f983de9e0287;p=thirdparty%2Flinux.git arm64: dts: qcom: x1e80100: Add GPU cooling Unlike the CPU, the GPU does not throttle its speed automatically when it reaches high temperatures. With certain high GPU loads it is possible to reach the critical hardware shutdown temperature of 120°C, endangering the hardware and making it impossible to run certain applications. Set up GPU cooling similar to the ACPI tables, by throttling the GPU speed when reaching 95°C and polling every 200ms.
