dvb_vb2_mmap(9)

💅 dvb_vb2_mmap(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a lil kernel function called dvb_vb2_mmap, and honestly? it's giving "trusted middleman" energy fr fr 🫶

---

✨ NAME ✨

dvb_vb2_mmap — the wrapper bestie that hands your stuff straight over to vb2_mmap() for Digital TV buffer handling 💖 like, it doesn't do the work itself, it just knows a girl who does 😌

---

🌸 SYNOPSIS 🌸

int dvb_vb2_mmap (struct dvb_vb2_ctx *ctx , struct vm_area_struct *vma
);

literally that's the whole signature, no cap 💅

---

🎀 ARGUMENTS 🎀

• ctx — the control struct for the VB2 handler 🧚 your main character struct, the one running the whole VB2 situation.
• vma — a pointer to a struct vm_area_struct that's carrying the vma which got passed to the mmap file operation handler over in the driver 🔥 so yeah, this is the vma that came from the driver's mmap handler, being handed along.

---

🦋 DESCRIPTION 🦋

map Digital TV video buffers into application address space ✨ that's it, that's the vibe — it takes those buffers and gets them mapped on into the address space of the app 🌈
