qman_dqrr_set_ithresh(9)

🎀 qman_dqrr_set_ithresh(9) — Kernel API Manual, section 9 🎀

ok bestie, welcome to the shortest little kernel API page, and it is literally all about setting a coalesce interrupt threshold. No cap. 💅

💖 NAME 💖

qman_dqrr_set_ithresh — Set coalesce interrupt threshold. That is the whole vibe: this function sets the coalesce interrupt threshold. Periodt. ✨

✨ SYNOPSIS ✨

The signature, exactly as it is, no edits:

int qman_dqrr_set_ithresh (struct qman_portal *portal , u8 ithresh );

🌸 ARGUMENTS 🌸

• portal — the portal you are setting the new value on. That is the target.
• ithresh — the new threshold value. Yep, that is it. 🎀

🦋 DESCRIPTION 🦋

It returns 0 on success, or a negative error code. That is the whole description, bestie — short, iconic, and to the point. 💅

Lowkey important: 0 means success, and a negative error code means something went sideways. No cap.
