| [ Upstream commit 5ba21fa11f473c9827f378ace8c9f983de9e0287 ] |
| |
| 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. |
