aggr_cpu_id__cache(9)

✨ aggr_cpu_id__cache(9) ✨

okay bestie, welcome to the aggr_cpu_id__cache(9) page from the Kernel API Manual 🫶 — this one is lowkey niche but highkey useful if you’re building an aggr_cpu_id from cache stuff.

🌸 NAME 🌸

aggr_cpu_id__cache — creates an aggr_cpu_id with the cache instache ID, cache level, die, and socket populated from the cache instache ID, cache level, die, and socket for cpu. Yes, “cache instache ID” is literally the wording, bestie 💀 — not me being quirky.

The function signature is compatible with aggr_cpu_id_get_t. Slay. 💅

🎀 SYNOPSIS 🎀

struct aggr_cpu_id aggr_cpu_id__cache (struct perf_cpu cpu , void *data
       );

That’s the whole vibe check: takes a struct perf_cpu cpu and a void *data, hands you back a struct aggr_cpu_id. ✨

💜 ARGUMENTS 💜

• cpu — -- undescribed -- 😭 the original page gives us literally nothing else here, so we are not inventing lore. no cap.
• data — -- undescribed -- 🙈 same energy: undescribed, bestie. the manpage said “not today” to details.
