STRUCT PSTATE_IDX_REVMAP_DATA(9)

💅 struct pstate_idx_revmap_data(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a lil struct deep in the cpufreq lore and honestly it's giving unsung hero ✨

✨ NAME ✨

struct pstate_idx_revmap_data — literally one single entry in the hashmap pstate_revmap, and that hashmap is indexed by a function of pstate id. no cap, that's the whole vibe 🫶

🌸 SYNOPSIS 🌸

struct pstate_idx_revmap_data {
    u8 pstate_id;
    unsigned int cpufreq_table_idx;
    struct hlist_node hentry;
 };

that's the whole struct, she's small but she's doing the work 💅

🎀 Members 🎀

• pstate_id — the pstate id for this entry. that's it, that's her whole job 💖
• cpufreq_table_idx — this is an index into the powernv_freqs cpufreq_frequency_table, for the frequency that corresponds to pstate_id. so like, id → table position → actual frequency, iykyk 🔥
• hentry — an hlist_node that hooks this entry into the pstate_revmap hashtable. she's literally holding the whole thing together, main character energy fr fr 👑
