💅 ixgbe_disable_pcie_primary — a little field guide 🎀

okay so bestie, welcome to the Kernel API Manual ✨ this one's about ixgbe_disable_pcie_primary, and honestly? the name is giving exactly what it does. no plot twists. let's go 🦋

🌸 NAME 🌸

ixgbe_disable_pcie_primary — literally just Disable PCI-express primary access. that's it. that's the whole vibe. 💅

✨ SYNOPSIS ✨

int ixgbe_disable_pcie_primary (struct ixgbe_hw *hw );

like, it returns an int and it takes one pointer. iconic minimalism 👑

🎀 ARGUMENTS 🎀

  • hw — pointer to hardware structure 🫶 (yes, that's the whole description, and honestly? she said what she said.)

💖 DESCRIPTION 💖

so what she does is: disables PCI-Express primary access and then verifies there are no pending requests. very "turn it off and double-check that it's actually off" of her. 🔥

and here's the return tea, iykyk: -EALREADY gets returned if the primary disable bit hasn't caused the primary requests to be disabled 😭 — like the bit tried but the requests said "no ma'am." otherwise you get 0 returned, which signifies primary requests disabled. slay ✅💅

ngl, if you see -EALREADY it's not a "you broke it" situation, it's a "the thing is still pending" situation. read the room. 🫶
