v4l2_m2m_resume(9)

💅 v4l2_m2m_resume(9) 💅

okay so bestie, this is v4l2_m2m_resume(9), pulled straight from the Kernel API Manual, and it's basically the "wake up, babe, we're running jobs again" little function. ✨

---

✨ NAME ✨

v4l2_m2m_resume — resume job running and try to run a queued job 🫶

---

🎀 SYNOPSIS 🎀

void v4l2_m2m_resume (struct v4l2_m2m_dev *m2m_dev );

It returns void, so there's no cute little return value to catch. 💅

---

🫶 ARGUMENTS 🫶

• m2m_dev — the opaque pointer to the internal data that handles the M2M context. literally the little all-access pass for the M2M internals 💖

---

🌸 DESCRIPTION 🌸

So this one gets called by a driver in the resume hook. It reverts the operation of v4l2_m2m_suspend and allows a job to be run. 🔥

It also tries to run a queued job if there is any. like, if there's a job waiting in the queue, it's giving it a little "go bestie, go" moment. 🏃‍♀️💨
