STRUCT CTI_DEVICE(9)

okay so bestie, this is struct cti_device(9) straight out of the Kernel API Manual, and it's literally just the vibe check for CTI device properties 💅 no cap, it's short and it slays.

💖 NAME 💖

struct cti_device — the description of CTI device properties. that's the whole assignment, and it ate ✨

🦋 SYNOPSIS 🦋

struct cti_device {
    int nr_trig_con;
    u32 ctm_id;
    struct list_head trig_cons;
    int cpu;
    const struct attribute_group **con_groups;
 };

🌸 Members 🌸

okay so here's the member-by-member tea ☕ and real talk, nr_trig_con is sitting right there in the struct but this list doesn't say one single thing about it, so I'm not gonna invent lore 🙈 the facts are the facts.

• ctm_id — which CTM this device is connected to. by default it's assumed there's a single CTM per SoC, ID 0 👑
• trig_cons — the list of connections to this device. it's giving "just a list" and honestly? iconic 💅
• cpu — the CPU ID if it's associated with a CPU, and -1 otherwise 🫶
• con_groups — the combined static and dynamic sysfs groups for trigger connections. both. together. we love to see it ✨

🌈 SEE ALSO 🌈

• Kernel file ./drivers/hwtracing/coresight/coresight-cti.h
• struct cti_config(9)
• struct cti_drvdata(9)

and that's the whole page fr fr — it lives over in ./drivers/hwtracing/coresight, it's dated October 2026, and it's called struct cti_device(9). mwah, go read the header bestie 💖🎀🧚
