radeon_msi_ok(9)

💅 radeon_msi_ok — the Kernel API Manual, bestie edition ✨

Okay so real talk, this one lives in the kernel API manual (section 9, radeon_msi_ok(9), periodt) and it's literally the vibe-check gatekeeper for MSIs on your radeon chip 🎀

---

🌸 NAME 🌸

radeon_msi_ok — asic specific msi checks, no cap 🦋

✨ SYNOPSIS ✨

bool radeon_msi_ok (struct radeon_device *rdev );

🫶 ARGUMENTS 🫶

• rdev — radeon device pointer. like, your actual card, bestie 💖

👑 DESCRIPTION 👑

So what this icon does is handle asic specific MSI checks to determine if MSIs should be enabled on a particular chip (and yes, all asics — every single one, fr fr).

Then it hands you back a verdict:

• returns true if MSIs should be enabled 🔥
• returns false if MSIs should not be enabled 💀

That's the whole job. main character energy, minimal drama, correct answer every time 🌈

ngl this is the kind of function that decides whether your interrupt setup gets to slay or gets sent home, so yeah, the boolean matters 🙈
