okay so bestie, this is struct xe_oa_unit from the Kernel API Manual — the literal Hardware OA unit 💅✨

🦋 SYNOPSIS 🦋

the struct is giving very “here is the whole vibe” energy, no cap:

struct xe_oa_unit {
    u16 oa_unit_id;
    struct xe_gt *gt;
    enum drm_xe_oa_unit_type type;
    struct xe_oa_regs regs;
    u32 num_engines;
    struct xe_oa_stream *exclusive_stream;
 };

💖 Members 💖

• oa_unit_id — identifier for the OA unit. iconic lil’ ID tbh 🎀
• gt — gt associated with the OA unit. yes bestie, that gt 🫶
• type — Type of OA unit - OAM, OAG etc. the whole “what kind of unit is this” moment ⭐
• regs — OA registers for programming the OA unit. programming regs, periodt 🔥
• num_engines — number of engines attached to this OA unit. counting the engines fr fr 🧚
