TTM_NUM_MOVE_FENCES(9)

✨ TTM_NUM_MOVE_FENCES ✨

okay so real quick — this is a page from the Kernel API Manual (section 9, the kernel-API girlies 🫶), and it's literally about one thing: a number. a limit. a vibe check for how much pipelined eviction your driver is allowed to get away with 💅

🌸 NAME 🌸

TTM_NUM_MOVE_FENCES — how many entities can be used for evictions 💖

---

🎀 SYNOPSIS 🎀

TTM_NUM_MOVE_FENCES

---

🦋 DESCRIPTION 🦋

okay so picture this: pipelined evictions can be spread on multiple entities 👀 like, not just one, several. and this thing right here? it's the max number of entities that can be used by the driver for that purpose. that's it. that's the whole tea. it's a ceiling, a cap, the "bestie you may not exceed this" of it all ✨

no cap, that's genuinely the entire description. short and iconic. periodt 💅
