STRUCT HISI_PTT_FILTER_DESC(9)

hey bestie! welcome to the Kernel API Manual page for struct hisi_ptt_filter_desc(9) — yes, we're doing kernel structs today and it's gonna slay 💅.

✨ NAME ✨

struct hisi_ptt_filter_desc — Descriptor of the PTT trace filter. That's the whole name, bestie, and yes it's giving "tiny but important struct" energy 💅.

🌸 SYNOPSIS 🌸

struct hisi_ptt_filter_desc {
    struct device_attribute attr;
    struct list_head list;
    bool is_port;
    char *name;
    u16 devid;
};

🎀 Members 🎀

• attr — the sysfs attribute of this filter. That's its whole job here, no cap.
• list — this descriptor's entry in the filter list. It's how the struct links up with the rest of the list girlies 🫶.
• is_port — tells you whether the filter's PCI device is a Root Port or not. Yes, it's a bool, and yes, it's serving "simple but crucial" 💖.
• name — the name of this filter, and it's the same as the name of the related PCI device. Matching names, matching vibes ✨.
• devid — the PCI device's devid of the filter. It's a u16, periodt.
