dpaa2_io_query_fq_count(9) 💅

okay so bestie, this lil’ icon lives in the Kernel API Manual, and it’s here to spill the tea on frame and byte counts for a given fq. no cap, it’s giving “debugging helper with main character energy.” 🎀

---

🌸 NAME 🌸

dpaa2_io_query_fq_count — get the frame and byte count for a given fq.

---

✨ SYNOPSIS ✨

int dpaa2_io_query_fq_count (struct dpaa2_io *d , u32 fqid , u32 *fcnt ,
       u32 *bcnt );

---

🎀 ARGUMENTS 🎀

• d — the given DPIO object. iconic pointer behavior, obviously.
• fqid — the id of the frame queue to be queried.
• fcnt — the queried frame count.
• bcnt — the queried byte count.

---

🦋 DESCRIPTION 🦋

Knowing the FQ count at run-time can be useful in debugging situations. The instantaneous frame- and byte-count are hereby returned. ✨

It returns 0 for a successful query, and a negative error code if the query fails. so basically: 0 = slay, negative = not slay. 😭
