qbman_swp_en...esc_mem_back(9)

Welcome to the Kernel API Manual, bestie 💖 — today’s page is qbman_swp_en...esc_mem_back(9), and yes, that abbreviated-looking title is exactly how it shows up. Buckle up, it’s giving kernel-core realness ✨

💖 NAME 💖

qbman_swp_enqueue_multiple_desc_mem_back — issue a multi enqueue command using multiple enqueue descriptor. That’s the whole name, no cap 🫶

🦋 SYNOPSIS 🦋

int qbman_swp_enqueue_multiple_desc_mem_back (struct qbman_swp *s ,
const struct qbman_eq_desc *d , const struct dpaa2_fd *fd , int
num_frames );

🎀 ARGUMENTS 🎀

• s — the software portal used for enqueue. Your main-character portal, basically 💅
• d — table of minimal enqueue descriptor
• fd — table pointer of frame descriptor table to be enqueued
• num_frames — number of fd to be enqueued

✨ DESCRIPTION ✨

Return the number of fd enqueued, or a negative error number. That’s the vibe check: count on success, negative error if it’s not giving 😭
