STRUCT CORESIGHT_OPS_SOURCE(9)

✨ struct coresight_ops_source(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this little page is all about struct coresight_ops_source and it's giving "kernel documentation but make it cute." Let's get into it 🫶

🌸 NAME 🌸

struct coresight_ops_source — the basic operations for a source. Like, the operations that are available for sources. That's the whole vibe. 👑

🦋 SYNOPSIS 🦋

here's the struct in all its glory, copy it exactly bestie, no cap:

struct coresight_ops_source {
    int (*enable)(struct coresight_device *csdev, struct perf_event
*event, enum cs_mode mode, struct coresight_path *path);
    void (*disable)(struct coresight_device *csdev, struct perf_event
*event);
    int (*resume_perf)(struct coresight_device *csdev);
    void (*pause_perf)(struct coresight_device *csdev);
 };

🎀 Members 🎀

• enable — enables tracing for a source ✨ like, it turns the tracing ON for a source, that's the whole job.
• disable — disables tracing for a source 💀 the opposite energy of enable, it turns tracing OFF for a source.
• resume_perf — resumes tracing for a source in a perf session 🔥 picking the tracing sesh back up, we love a comeback.
• pause_perf — pauses tracing for a source in a perf session 🙈 hitting pause on tracing in a perf session, very main character of it.

🌈 SEE ALSO 🌈

kernel file ./include/linux/coresight.h, plus the whole friend group: union coresight_dev_subtype(9), struct coresight_platform_data(9), struct csdev_access(9), struct coresight_desc(9), struct coresight_connection(9), struct coresight_sysfs_link(9), struct coresight_device(9), struct coresight_path(9), struct coresight_ops_sink(9), struct coresight_ops_link(9), struct coresight_ops_helper(9), and struct coresight_ops_panic(9) — literally the entire squad, go say hi 🦋💜

and that's the page bestie! 🎀 sign-off time: this one lives in ./include/linux and it's dated October 2026 — the header said struct coresight_ops_source(9) and the footer said it again, so now you know the whole lore 💖 slay, periodt, go read some kernel source ✨🧚
