STRUCT THERMAL_DEBUGFS(9)

💖 NAME

okay so bestie, this is struct thermal_debugfs(9) from the Kernel API Manual — and it's literally the high level structure for a thermal object in debugfs 💅✨. It's giving shared-base-camp-for-thermal-debugfs-stats, and I'm obsessed.

✨ SYNOPSIS ✨

       struct thermal_debugfs {
           struct dentry *d_top;
           struct mutex lock;
           union {
             struct cdev_debugfs cdev_dbg;
             struct tz_debugfs tz_dbg;
           };
        };

🎀 Members 🎀

• d_top — top directory of the thermal object directory. directory queen behavior 👑.
• lock — per object lock to protect the internals. do not touch the internals without the lock, periodt 🔒.
• {unnamed_union} — anonymous. it's literally unnamed, bestie 🙈.
• cdev_dbg — a cooling device debug structure 🧊.
• tz_dbg — a thermal zone debug structure 🌡️.

🦋 Description 🦋

The thermal_debugfs structure is the common structure used by the cooling device or the thermal zone to store the statistics. That's highkey the whole assignment: one shared struct, two possible thermal besties, all the stats stored in it. no cap 💖.
