pp_features(9)

💖 pp_features(9) — powerplay feature slay 💖

okay so bestie, this is pp_features(9) from the Kernel API Manual, and it’s literally the sysfs file that lets you adjust what powerplay features get enabled. The amdgpu driver provides this sysfs API, and the file is called pp_features. Iconic. No notes.

🚨 heads up, bestie: this is only available for Vega10 and later dGPUs.

When you read the file back, it shows you the following, lowkey very useful:

• The current ppfeature masks.
• A full list of all supported powerplay features with their naming, bitmasks, and enablement status — Y/N means “enabled”/“disabled”.

To manually enable or disable a specific feature, just set or clear the corresponding bit from the original ppfeature masks and input the new ppfeature masks. That’s the whole vibe. ✨
