ocxl_global_mmio_clear64(9)

💅 ocxl_global_mmio_clear64 — like, the whole manual page, bestie

okay so this is a page from the Kernel API Manual (yes, the kernel, we're built different over here) and it's all about one little function that clears bits in a 64-bit global MMIO register. no cap, that's it, that's the vibe 🎀

✨ NAME ✨

ocxl_global_mmio_clear64 — Set bits in a 64 bit global MMIO register 🔥

(and yes bestie, the description literally says set, even though the function is called clear. I am simply the messenger. iykyk 💀)

---

🦋 SYNOPSIS 🦋

int ocxl_global_mmio_clear64 (struct ocxl_afu *afu , size_t offset ,
enum ocxl_endian endian , u64 mask );

it's giving "small signature, big responsibilities" honestly 😭

---

🌸 ARGUMENTS 🌸

• afu — The AFU 💖 like, the actual function unit you're poking at. main character energy fr.
• offset — The Offset from the start of MMIO ✨ measured from the very beginning of the MMIO, so don't go wandering off on your own.
• endian — the endianness that the MMIO data is in 🦋 yes, the byte-order situation. gotta respect it.
• mask — a mask of the bits to set 👑 like, the exact bits you're targeting. be precise with it.

---

💜 DESCRIPTION 💜

Returns 0 for success, negative on error ⭐ that's the whole description and honestly? iconic. short, sweet, zero notes.

ngl bestie, that's all the original gives us — so that's all you get. no extra lore, no invented behaviour. we stay factual in this group chat 🫶

and that's the page!! mwah 💋 this little manual lives in ./include/misc and it's dated October 2026 — so yeah, future vibes only. slay, go clear those bits (or set them, apparently 💀). periodt. 🌟
