DRM CLIENT USAGE STATS(9)

💖 DRM Client usage stats(9) 💖

okay so bestie, this is the DRM Client usage stats page from the Kernel API Manual — section 9, main character energy only. ✨

The drm/xe driver implements the DRM client usage stats specification as documented in :ref:\drm-client-usage-stats``. that's the whole assignment, no cap. 💅

The example below shows the implemented key/value pairs and the entirety of the currently possible format options. There's a lone : sitting right before the block in the source — yes, literally, keep it in your notes. 🎀
