✨ aggr_cpu_id__cluster(9) ✨

okay so bestie, welcome to the aggr_cpu_id__cluster(9) page from the Kernel API Manual 💅 this one is short but she's got a job and she does it.

💖 NAME 💖

aggr_cpu_id__cluster — makes you a fresh aggr_cpu_id where cluster, die and socket are all filled in with the cluster, die and socket for cpu. and like, the function signature is compatible with aggr_cpu_id_get_t. slay 🎀

🦋 SYNOPSIS 🦋

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

🌸 ARGUMENTS 🌸

• cpu — -- undescribed -- 😭 that's literally what the source says, bestie. no description. she's mysterious. main character energy.
• data — -- undescribed -- 🙈 also undescribed. iconic of them honestly.

👑 SEE ALSO 👑
