aggr_cpu_id__core(9)

💅 aggr_cpu_id__core(9) — Kernel API Manual 💅

🌸 NAME 🌸

okay so aggr_cpu_id__core is literally here to Create an aggr_cpu_id with the core, cluster, die and socket populated with the core, die and socket for cpu. The function signature is compatible with aggr_cpu_id_get_t — slay, no cap. 💖

✨ SYNOPSIS ✨

The whole signature is giving exactly this, bestie:

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

🎀 ARGUMENTS 🎀

• cpu — -- undescribed -- (the manual is keeping it mysterious, and I respect the main-character privacy 😭)
• data — -- undescribed -- (same energy: the page does not spill the tea 🙈)
