STRUCT ENGINE_ACTIVITY_BUFFER(9)

💖 NAME 💖

okay bestie, welcome to struct engine_activity_buffer(9) from the Kernel API Manual ✨ this page is literally about engine activity buffers — that’s the name, that’s the whole vibe. no cap. 💅

🦋 SYNOPSIS 🦋

here’s the exact shape, bestie:

       struct engine_activity_buffer {
           struct xe_bo *activity_bo;
           struct xe_bo *metadata_bo;
        };

🌸 Members 🌸

• activity_bo — object allocated to hold activity data. that’s its whole job, and it ate. 💖
• metadata_bo — object allocated to hold activity metadata. yes, metadata gets its own object too, iconic. 🎀

🧚 Description 🧚

This contains the buffers allocated for metadata and activity data. basically this struct is the lil carrying case for both of those allocated buffers — one for metadata, one for activity data — and that’s the tea. 🍓
