STRUCT DRM_XE_OA_CONFIG(9)

💖 NAME 💖

struct drm_xe_oa_config — OA metric configuration. Bestie, this page is straight out of the Kernel API Manual, and it’s literally the struct that holds your OA metric config energy. 🎀

🌸 SYNOPSIS 🌸

okay so here’s the exact shape, no edits, no remix:

       struct drm_xe_oa_config {
           __u64 extensions;
           char uuid[36];
           __u32 n_regs;
           __u64 regs_ptr;
        };

• extensions — pointer to the first extension struct, if any 👀 like, if there even is one.
• uuid — a string formatted like "08x-04x-04x-04x-012x" ✨ yes, exactly like that.
• n_regs — number of regs in regs_ptr 🔢
• regs_ptr — pointer to (register address, value) pairs for OA config registers. The expected length of the buffer is: (2 * sizeof(u32) * n_regs). 🧚

✨ Description ✨

Multiple OA configs can be added using DRM_XE_OBSERVATION_OP_ADD_CONFIG. 🦋

A particular config can be specified when opening an OA stream using the DRM_XE_OA_PROPERTY_OA_METRIC_SET property. periodt 💅
