The once sent by Andre in this series is clean, simple and logical. Reviewed-by: Aditya Garg Tested-by: Aditya Garg # MacBookPro16,1 with AMD Radeon Pro 5300M Support for more models as claimed by the vibe coded patch should be done after appropriate feedback from the users in another series. Unfortunately after every few kernel versions the most number of regressions we face are from AMD GPU drivers and untested patches are the cause everytime.
