STRUCT CONT_REC(9)

💅 struct cont_rec(9) — like, the continuous recording data structure bestie 🎀

Okay so this is a page from the Kernel API Manual, and we're about to get so cozy with one little struct. Come on, iykyk ✨

---

🌸 NAME 🌸

struct cont_rec — the continuous recording data structure. That's it, that's the whole vibe. She holds the state for continuous recording, no cap 💖

---

✨ SYNOPSIS ✨

Here's her whole lewk, verbatim, don't touch a single character:

struct cont_rec {
    u32 prev_wr_ptr;
    u32 prev_wrap_cnt;
    u8 state;
    struct mutex mutex;
 };

Literally four members and she's iconic for it 👑

---

🦋 Members 🦋

• prev_wr_ptr — the last address that was read in the monitor_data debugfs file. Like a little bookmark 🎀, but for read positions.
• prev_wrap_cnt — the wrap count that was used during the last read in the monitor_data debugfs file. She's keeping track of how many times we've looped around the ring, ngl 🌀
• state — the state of the monitor_data debugfs file, exactly as described in the iwl_fw_mon_dbgfs_state enum. Vibe check, but as an enum 💅
• mutex — locked while reading from the monitor_data debugfs file. Yes bestie, we're doing proper locking, no chaotic concurrent reads in this house 🙈🔒
