New Documentation Aims To Help Improve AMD Zen System Debugging On Linux
In hoping to ease the experience for Linux enthusiasts and desktop users work through various potential hardware issues when running with AMD Zen (Ryzen) systems on Linux, a new documentation proposal adds a lot of helpers to the Linux kernel documentation area for dealing with different hardware woes.
Plus the AMD EPYC server platforms tend to be much better vetted and running solid on Linux given the dominant use there and so this documentation guide mostly of relevance to Ryzen systems. The documentation authored by AMD Linux engineer Mario Limonciello covers S3 and s2idle topics, other suspend/resume issues like NVMe disk storage disappearing, core offlining problems, spurious IRQs, run-time power management / ASPM / EPP policy, and more. Related to this is now also being a amd-debug-tools Git repository with some Python scripts for helping to work through AMD P-State, s2idle, and Panel Self Refresh issues.
