STRUCT DVB_USB_ADAPTER_PROPERTIES(9)

💅 struct dvb_usb_adapter_properties(9) — aka the Kernel API Manual glow-up 🎀

okay bestie, welcome to the Kernel API Manual entry for struct dvb_usb_adapter_properties, and no cap this thing is literally just "properties of dvb usb device adapter" ✨ like that's the whole vibe. it's the little struct that tells the kernel everything it needs to know about one adapter on a dvb usb device. lowkey iconic.

✨ NAME ✨

struct dvb_usb_adapter_properties — properties of dvb usb device adapter 🦋

---

🌸 SYNOPSIS 🌸

okay so here's the whole struct, copy it exactly, do not freestyle:

struct dvb_usb_adapter_properties {
  #define MAX_NO_OF_FE_PER_ADAP 3;
  #define DVB_USB_ADAP_HAS_PID_FILTER               0x01;
  #define DVB_USB_ADAP_PID_FILTER_CAN_BE_TURNED_OFF 0x02;
  #define DVB_USB_ADAP_NEED_PID_FILTERING           0x04;
    u8 caps;
    u8 pid_filter_count;
    int (*pid_filter_ctrl) (struct dvb_usb_adapter *, int);
    int (*pid_filter) (struct dvb_usb_adapter *, int, u16, int);
    struct usb_data_stream_properties stream;
 };

those #defines go hard honestly — MAX_NO_OF_FE_PER_ADAP is 3;, and the three cap flags are 0x01, 0x02, 0x04 🫶

👑 Members 👑

• caps — the adapter's capabilities. it's a u8 and it's giving "i contain flags" energy 💅
• pid_filter_count — the pid count of the adapter's pid-filter. yes, how many pids. that's the whole thing 🔥
• pid_filter_ctrl — a function pointer, int (*pid_filter_ctrl) (struct dvb_usb_adapter *, int), and it gets called to enable/disable the pid-filter. she's the on/off switch bestie ⭐
• pid_filter — a function pointer, int (*pid_filter) (struct dvb_usb_adapter *, int, u16, int), called to set/unset a pid for filtering. the actual filter gremlin 🙈
• stream — the adapter's usb stream configuration, typed struct usb_data_stream_properties. main character energy fr fr 🌈

mwah 💖 that's the whole page, every flag and every member accounted for, no skips, no cap.

okay that's a wrap bestie — this one came from ./drivers/media/usb/dvb-usb-v2, dated October 2026, and it's page struct dvb_...r_properties(9) 🎀 slay, go forth and filter your pids 🌸
