💅 vb2_queue_al..._cache_hints(9) — Kernel API Manual ✨

Okay so bestie, welcome to the vb2_queue_allows_cache_hints(9) page from the Kernel API Manual 🫶 this is the whole vibe, and we're keeping every detail because that's the assignment.

💖 NAME 💖

vb2_queue_allows_cache_hints — returns true if the queue allows cache and memory consistency hints. That's the whole entire check, no cap: it's giving very important little boolean energy for whether cache and memory consistency hints are allowed on this queue 💅

✨ SYNOPSIS ✨

Here's the signature, bestie — keep it exactly as it is, character for character, because we do not freestyle kernel signatures in this group chat 😭

bool vb2_queue_allows_cache_hints (struct vb2_queue *q );

🫶 ARGUMENTS 🫶

• q — a pointer to a struct vb2_queue with the videobuf2 queue. That's the queue you're asking about, and she is literally the main character of this check 👑

🌈 SEE ALSO 🌈

mwah 💋 that's the whole page, and it's giving very demure, very kernel-core. This one comes from ./include/media, dated October 2026, and the page is literally vb2_queue_al..._cache_hints(9). bye bestie 🎀✨
