✨ NAME ✨

struct bdisp_dbg — debug info. That's the whole name vibe, no cap.

🌸 SYNOPSIS 🌸

       struct bdisp_dbg {
           struct dentry           *debugfs_entry;
           struct bdisp_node       *copy_node[MAX_NB_NODE];
           struct bdisp_request    copy_request;
           ktime_t hw_start;
           s64 last_duration;
           s64 min_duration;
           s64 max_duration;
           s64 tot_duration;
        };
