qbman_swp_fq_force(9)

💖 NAME 💖

hey bestie! welcome to the Kernel API Manual page for qbman_swp_fq_force(9) ✨ this one is literally about forcing the FQ to fully scheduled state, and it's giving main-character energy. 🎀

✨ SYNOPSIS ✨

int qbman_swp_fq_force (struct qbman_swp *s , u32 fqid );

🎀 ARGUMENTS 🎀

• s — the software portal object. 🌀
• fqid — the index of frame queue to be forced. 🎯

💅 DESCRIPTION 💅

okay so the “Force eligible” behavior will force a tentatively-scheduled FQ to be fully-scheduled, so it's available for selection by any channel-dequeuing behaviour (push or pull). 💅 no cap, that's the whole glow-up.

and if the FQ is subsequently “dequeued” from the channel and is still empty at the time this happens, the resulting dq_entry will have no FD. 😭 (translation: qbman_result_DQ_fd will return NULL.)

it returns 0 for success, or a negative error code for failure. 🫶
