igb_request_msix(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… igb_request_msix β€” the igb_request_msix(9) page, bestie edition πŸŽ€

okay so this is a page from the Kernel API Manual (that's the manual name, no cap) and it's all about one lil function. it lives in the land of ./drivers/net/ethernet/intel/igb and it's dated October 2026 β€” we love a timestamped queen. ✨


🌸 NAME 🌸

igb_request_msix β€” literally just "Initialize MSI-X interrupts." that's the whole vibe. short, sweet, iconic. πŸ’–


πŸ¦‹ SYNOPSIS πŸ¦‹

int igb_request_msix (struct igb_adapter *adapter );

it returns an int, it takes one pointer, that's it. she's lowkey minimal. 🫢


πŸ“ ARGUMENTS πŸ“

  • adapter β€” the board private structure you're gonna initialize. that's your girl, your main character struct, the thing getting set up. πŸ‘‘

🌈 DESCRIPTION 🌈

so what does she do, you ask? igb_request_msix allocates MSI-X vectors and requests interrupts from the kernel. both. she's multitasking. πŸ’…

like, the vectors get allocated, the interrupts get requested, and the kernel is looped in. that's the whole deal, fr fr. no hidden lore, no extra steps. πŸ”₯
