STRUCT MSM_PERFCNTR_GROUP_STATE(9)

💅 struct msm_perfcntr_group_state(9)

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, and yes this page is a whole vibe. it's all about struct msm_perfcntr_group_state, which is the tracking for the currently allocated counter state ✨

🌸 NAME

struct msm_perfcntr_group_state — tracking for the currently allocated counter state 🎀

✨ SYNOPSIS

struct msm_perfcntr_group_state {
    unsigned allocated_counters;
    uint32_t countables[];
};

🫶 Members

• allocated_counters — the allocated counters for global counter collection, no cap. the way this works is the corresponding counters get allocated from highest to lowest, and the whole point of that order is to minimize the chance of conflict with old userspace, which allocates from lowest to highest. literally strategic 💅
• countables — the corresponding SELect reg values for the allocated counters. the other half of the situation, iconic behavior honestly 🦋
