ps3_lpm_open(9)

okay so, hi bestie 💖 welcome to ps3_lpm_open(9) — this is the Kernel API Manual page for opening the logical performance monitor device. It’s giving kernel-level main character energy, and we’re gonna walk through every single arg, no cap.

💖 NAME 💖

ps3_lpm_open — open the logical performance monitor device. periodt. 💅

✨ SYNOPSIS ✨

This is the exact signature, bestie — don’t let the line wrap scare you:

int ps3_lpm_open (enum ps3_lpm_tb_type tb_type , void *tb_cache , u64
       tb_cache_size );

🎀 ARGUMENTS 🎀

Okay, three things go in, and here’s the vibe check on each:

• tb_type — specifies the type of trace buffer that lv1 should use for this lpm instance, and it’s specified by one of the values in enum ps3_lpm_tb_type. Slay. ✨
• tb_cache — optional user-supplied buffer to use as the trace buffer cache. If it’s NULL, the driver will allocate and manage an internal buffer. It’s unused when tb_type is PS3_LPM_TB_TYPE_NONE.
• tb_cache_size — the size in bytes of the user-supplied tb_cache buffer. It’s unused when tb_cache is NULL or tb_type is PS3_LPM_TB_TYPE_NONE.
