STRUCT XE_OA_GT(9)

💖 NAME 💖

struct xe_oa_gt - OA per-gt information. This is the struct xe_oa_gt(9) page from the Kernel API Manual, and yes bestie, we are keeping every single detail. It's giving "small struct, big main character energy" ✨

✨ SYNOPSIS ✨

       struct xe_oa_gt {
           struct mutex gt_lock;
           u32 num_oa_units;
           struct xe_oa_unit *oa_unit;
           u32 whitelist_count;
        };

🌸 Members 🌸

• gt_lock — the lock protecting create/destroy OA streams. Gatekeeping the streams, as she should 💅
• num_oa_units — number of oa units for each gt. Literally counting the units, no cap 🔥
• oa_unit — array of oa_units. A whole little lineup of them, slay ✨
• whitelist_count — number of open streams for which oa registers are whitelisted. Keeping track of who's allowed in the club 🎀
