virtsnd_ctl_notify_cb(9)

okay bestie, welcome to virtsnd_ctl_notify_cb(9) from the Kernel API Manual — this is the callback page, and it's literally all about handling completed control messages. Let's get into it. 💖

✨ NAME ✨

virtsnd_ctl_notify_cb — Process all completed control messages. No cap, that's the whole name vibe. 💅

🎀 SYNOPSIS 🎀

void virtsnd_ctl_notify_cb (struct virtqueue *vqueue );

🍓 ARGUMENTS 🍓

• vqueue — the underlying control virtqueue. That's the queue underneath it all, bestie. 🫶

💜 DESCRIPTION 💜

This callback function is called upon a vring interrupt request from the device. Periodt — that's the trigger, fr fr. When the device sends that vring interrupt request, this callback gets the call. ✨

🌸 CONTEXT 🌸

It runs in interrupt context ⚠️. It takes and releases the control queue spinlock. Like, both of those things, no cap. 💅
