STRUCT DRM_XE_OA_STREAM_INFO(9)

💅 NAME 💅

struct drm_xe_oa_stream_info — the OA stream info that gets handed back to you from the %DRM_XE_OBSERVATION_IOCTL_INFO observation stream fd ioctl ✨

(also hi bestie, this is a page from the Kernel API Manual, and the struct is literally the whole main character here 🫶)

🦋 SYNOPSIS 🦋

okay so here's the whole vibe, character for character:

struct drm_xe_oa_stream_info {
    __u64 extensions;
    __u64 oa_buf_size;
    __u64 reserved[3];
 };

that's it. that's the struct. she's small but she's doing her job 💅

🎀 Members 🎀

• extensions — pointer to the first extension struct, if any. yep, the "if any" is doing heavy lifting there, no cap 🌸
• oa_buf_size — the OA buffer size. that's the number, bestie 📏
• reserved — reserved for future use 🙈 like, don't touch, it's not for you yet, it's saving seats for future structs 👑

🌈 SEE ALSO 🌈

the whole friend group, and yes you're gonna say hi to every single one of them, i don't make the rules 💖

that's the whole page, bestie, go read your structs 💜

anyway this lil icon was living at ./include/uapi/drm, dated October 2026, and yes she signed her own page as struct drm_x..._stream_info(9) because she's extra like that. mwah 💋✨
