isst_if_mbox_cmd_set_req(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

Okay bestie, so this one's called isst_if_mbox_cmd_set_req — and what it does is literally just check whether a mailbox command is a set request. That's it. That's the whole vibe. ✨ (It's a (9) kernel API page, so it's giving "I live in the driver layer" energy, iykyk.)

🎀 SYNOPSIS 🎀

bool isst_if_mbox_cmd_set_req (struct isst_if_mbox_cmd *cmd );

Like, the return type is bool and it takes one pointer. Short and iconic. No cap. 👑

🦋 ARGUMENTS 🦋

  • cmd — pointer to the command structure you want verified. Yes, you have to hand it over. It's not gonna go find it itself, bestie 🫶

🌸 DESCRIPTION 🌸

So the whole ~point~ of this function is checking whether the mailbox level you passed in is a set request and not a get request. That's the vibe check it performs. Set? Slay. Get? Not its problem. 💅

It's highkey a tiny little classifier and honestly? Respect. Small functions doing one thing are main character energy fr fr.

⭐ RETURN ⭐

It comes back with true if the command is a set_req, and false otherwise. That's the whole story — binary, clean, no drama. 💖

Heads up: true = it is a set request. false = it isn't. Don't overthink it, queen, it's literally two options. 🌈

🔥 SEE ALSO 🔥

The kernel file lives right here — copy it exactly, don't @ me:

./drivers/platform/x86/intel/speed_select_if/isst_if_common.c

And these iconic siblings in the same universe, go give them a read:

Okay that's the page!! A whole function whose entire job is answering one yes/no question and honestly we should all be so lucky. 🌸 Go check mailboxes responsibly, bestie.

Sign-off time: this lil gem is pulled from ./drivers/platform/x86/intel/s... (the isst_if_common.c file above, you know the one), dated October 2026, and it is — say it with me — isst_if_mbox_cmd_set_req(9). Periodt. 💅✨
