💅 NAME

vdec_msg_queue_update_ube_wptr — bestie, this one is literally used to update the ube write point. that's it, that's the whole job 🎀

---

✨ SYNOPSIS ✨

void vdec_msg_queue_update_ube_wptr (struct vdec_msg_queue *msg_queue ,

so you're calling it like that, okay? mind the space before that comma, she's quirky like that 💅

🫶 ARGUMENTS 🫶

• msg_queue — okay so this is the struct vdec_msg_queue *, and bestie she is used to store the lat buffer information. that's her whole purpose. iconic of her honestly 🦋
• ube_wptr — a uint64_t holding the current ube write point. that's the vibe. current. write point. no cap ✨

🌈 SEE ALSO 🌈

okay so this is the part where I put you on to the whole friend group 🫶 first up, the kernel file, and pls copy this path exactly, no typos, I'm begging 🙈:

./drivers/media/platform/mediatek/vcodec/decoder/vdec_msg_queue.h — and there's an enum in there too, iykyk 👑

and then the whole crew, all of them, in this exact order, no skipping (this is a vibe check and you will pass it 💀):

• core_ctx_status(9)
• struct vdec_msg_queue_ctx(9)
• struct vdec_lat_buf(9)
• struct vdec_msg_queue(9)
• vdec_msg_queue_init(9)
• vdec_msg_queue_init_ctx(9)
• vdec_msg_queue_qbuf(9)
• vdec_msg_queue_dqbuf(9)
• vdec_msg_queue_update_ube_rptr(9)
• vdec_msg_queue_wait_lat_buf_full(9)
• vdec_msg_queue_deinit(9)

like look at all those man page girlies, they ate fr fr 🔥 and yeah vdec_msg_queue_update_ube_rptr(9) is right there next to her sister wptr, they're a matching set, obsessed 💜

ngl this page is a short one but every single name up there is load-bearing, so don't be out here assuming you can skip the cast list 😭
