amdgpu_msi_ok(9)

💖 amdgpu_msi_ok(9) 💖

okay bestie, so this is a page from the Kernel API Manual (that's the manual name, love that for us) and it's all about one teeny tiny little function that's basically the vibe check for MSI ✨

---

🌸 NAME 🌸

amdgpu_msi_ok — check whether MSI functionality is enabled 🎀

---

🦋 SYNOPSIS 🦋

bool amdgpu_msi_ok (struct amdgpu_device *adev );

---

💅 ARGUMENTS 💅

• adev — amdgpu device pointer. and she is unused, bestie 😭 literally just vibing there in the parameter list, contributing nothing. iconic behavior honestly 🫶

---

✨ DESCRIPTION ✨

so the way this works is: it checks whether MSI functionality has been disabled via module parameter 💀 and yes — this applies to all ASICs, no exceptions, no cap. every single one gets the same treatment 👑

it's giving "one job" energy and honestly? she ate.

---

🌈 RETURN 🌈

• *true* if MSIs are allowed to be enabled ✨
• *false* otherwise 🙈

that's it. that's the whole personality. a bool. a queen 👑💜
