STRUCT CROS_EC_DEBUGFS(9)

✨ NAME ✨

struct cros_ec_debugfs — literally all the EC debugging info, bestie 💅

okay so real quick, this is a page from the Kernel API Manual, section 9 — yes, the struct cros_ec_debugfs(9) girlies know exactly what's up 🎀

🌸 SYNOPSIS 🌸

struct cros_ec_debugfs {
    struct cros_ec_dev *ec;
    struct dentry *dir;
    struct circ_buf log_buffer;
    struct cros_ec_command *read_msg;
    struct mutex log_mutex;
    struct delayed_work log_poll_work;
    struct debugfs_blob_wrapper panicinfo_blob;
    struct notifier_block notifier_panic;
 };

🦋 Members 🦋

she's got a whole lil cast of characters, let's meet them 🫶

• ec — the EC device that this debugfs information actually belongs to. main character energy, honestly 👑
• dir — the dentry for the debugfs files. it's giving "where the files live" 🏠
• log_buffer — a circular buffer holding onto console log information 🔄
• read_msg — a preallocated EC command and its buffer, ready to read the console log. prepared, organized, iconic ✨
• log_mutex — a mutex whose whole job is protecting that circular buffer. don't touch it without her 🚧
• log_poll_work — a recurring task that polls the EC for new console log data. she just keeps showing up, no cap 🔁
• panicinfo_blob — the panicinfo debugfs blob 🫧
• notifier_panic — a notifier_block that lets the kernel flush the buffered log when the EC panics. lowkey important, highkey a lifesaver 😭
