Title: [SRU] eDP showing garbage on GPT1 platforms Status in linux-firmware package in Ubuntu: New Bug description: [ Impact ] On 6.14.0-33-generic, on the AMD GPT1-based OEM platforms, with the current linux-firmware the eDP will not function normally. It shows only garbage on the screen. This has been observed on some latest HP and Lenovo platforms. [ Fix ] Update the PSP_14_0_0 bins to the latest. This includes the following files: 1. amdgpu/psp_14_0_0_ta.bin 2. amdgpu/psp_14_0_0_toc.bin The upstream commit 6a2f118a5a90dbc65[1] contains the said PSP firmware files. [ Test ] 1. Install the kernel and the updated linux-firmware on the said GPT1 platforms. 2. Boot into the OS. The eDP should not show garbage. 4. Repeat the above steps on a platform with STRIX processor. The eDP should also function normally. [ Where the problems could occur ] This should affect only the PSP 14.0.0 hardware. This currently affects the GPT1 and STRIX[2] platfroms.
