📦 version 7.3.1, in nixpkgs unstable

💅 mei_cl_tx_flow_ctrl_creds_reduce — bestie edition ✨

okay so this is a little function from the Kernel API Manual, section 9, and it's literally here to reduce transmit flow control credits for a client. yes, that's the whole vibe. let's get into it 🎀

✨ SYNOPSIS ✨

int mei_cl_tx_flow_ctrl_creds_reduce (struct mei_cl *cl );

🌸 ARGUMENTS 🌸

  • cl — the host client. that's the one we're working with, bestie 🫶

💖 RETURN 💖

so it returns 0 on success — slay, we love a zero.

but if ctrl credits are <= 0, it hits you with -EINVAL. yeah. that's the error. no cap 😭

🔥 SEE ALSO 🔥

okay this list is long but we don't skip, we don't scroll past. every single one, periodt:

Kernel file ./drivers/misc/mei/client.c

like, that's the whole squad. iykyk 💀

bestie reminder: -EINVAL shows up when ctrl credits are <= 0, so maybe vibe check your credits first 🙈

okay and finally, the ~official~ deets so we're being legit: this page lives under ./drivers/misc/mei, it's dated October 2026, and the manual header/footer both say mei_cl_tx_fl...creds_reduce(9). mwah, that's a wrap 💋👑🌈
