clear_exclus...cxl_commands(9)

✨ clear_exclusive_cxl_commands — a Kernel API Manual moment ✨

okay bestie so you're reading the clear_exclus...cxl_commands(9) page from the Kernel API Manual and honestly? it's a short one but it EATS. let's get into it 💅

---

🌸 NAME 🌸

clear_exclusive_cxl_commands — atomically enable user cxl commands

like… that's the whole vibe. it flips commands from "exclusive, hands off" to "available for userspace", and it does it atomically, no cap. 🔥

---

🦋 SYNOPSIS 🦋

void clear_exclusive_cxl_commands (struct cxl_memdev_state *mds ,
unsigned long *cmds );

it returns void, so no return value to stress about — she just does the thing and leaves. main character energy fr fr. ✨

---

🎀 ARGUMENTS 🎀

• mds — The device state to modify. yes, this is the thing you're touching. the device state. she's the one getting modified. 🫶
• cmds — bitmap of commands to mark available for userspace. it's a bitmap, bestie, so it's bits and it's marking which commands become available to userspace. iconic. 💖

---

👑 SEE ALSO 👑

ok so the kernel file for this one lives at ./drivers/cxl/core/memdev.c — that's the source of truth, go look if you're curious 👀

and the whole friend group of related calls:

• cxl_set_capacity(9)
• set_exclusive_cxl_commands(9)
• cxl_mem_get_fw_info(9)
• cxl_mem_activate_fw(9)
• cxl_mem_abort_fw_xfer(9)

like a little cxl squad. one of them literally does the opposite (set_exclusive_cxl_commands), so you already know the lore. 🌈

---

lowkey reminder: the synopsis is literally the whole API surface here — two args, no return, done. don't go inventing extra params, she's perfect as she is 💀

mwah — huge slay to ./drivers/cxl/core, dated October 2026, and that's the clear_exclus...cxl_commands(9) page signing off. go be atomically enabled, bestie 🧚💜
