rdma_set_cq_moderation(9)

✨ rdma_set_cq_moderation ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a little kernel-side baddie from rdma_set_cq_moderation(9) and she is, like, literally here to change how chatty your CQ is. buckle up 🎀

🌸 NAME 🌸

rdma_set_cq_moderation — modifies moderation params of the CQ 💅

🦋 SYNOPSIS 🦋

int rdma_set_cq_moderation (struct ib_cq *cq , u16 cq_count , u16
cq_period );

💜 ARGUMENTS 💜

• cq — the CQ you're about to modify, bestie. that's the one. 👑
• cq_count — number of CQEs that will trigger an event. like, how many lil completion entries pile up before she finally speaks up 🗣️✨
• cq_period — max period of time in usec before triggering an event. so even if the count never gets there, she'll still ping you after this many microseconds ⏱️💖
