DRM_ASAHI_BARRIER_NONE(9)

💅 DRM_ASAHI_BARRIER_NONE 💅

okay so real quick, this is a page from the Kernel API Manual, and it's about one tiny little constant that basically means "no waiting bestie" ✨

---

🌸 NAME 🌸

DRM_ASAHI_BARRIER_NONE — the command index for no barrier, like, at all, none, zero, bye 👋

---

🎀 SYNOPSIS 🎀

DRM_ASAHI_BARRIER_NONE

that's it. that's the whole synopsis. iconic honestly 💅

---

🦋 DESCRIPTION 🦋

okay so picture this: there's this special value, right? and you can pass it into drm_asahi_command::vdm_barrier or drm_asahi_command::cdm_barrier, and what it's telling the kernel is literally just — “hey, this subqueue? she does not wait on any previous work.” no queueing behind the older stuff, no looking back, main character energy only 👑

so if you're the type to set a barrier field and you're like “actually no, I don't want a barrier,” this is the value you reach for. it's giving "I'm free tonight" 💀✨
