πŸ’… genwqe_set_interrupt_capability(9) β€” like, the Kernel API Manual edition πŸŽ€

okay so bestie, real talk: this page lives in section 9 of the kernel API manual, and it's all about one lil' function that sets up your MSI capability structure. it's giving "small function, big responsibility" energy fr fr ✨


🌸 NAME 🌸

genwqe_set_interrupt_capability β€” configure the MSI capability structure. no cap, that's literally the whole job πŸ’–


πŸ¦‹ SYNOPSIS πŸ¦‹

int genwqe_set_interrupt_capability (struct genwqe_dev *cd , int count );

she's a function, she returns an int, and she takes exactly two arguments β€” we love a low-maintenance icon πŸ‘‘


✨ ARGUMENTS ✨

  • cd β€” pointer to the device 🫢 like, hand her the actual device struct and she'll take it from there.
  • count β€” the number of vectors to allocate 🌈 so you're telling her how many you want, bestie. be honest with her.

πŸ”₯ RETURN πŸ”₯

  • 0 β€” returned if there's no error ⭐ that's it. zero means we ate, we slayed, we're done. periodt.
heads up babe, the page only promises 0 for "no error" β€” it doesn't spell out what a non-zero value looks like, so don't go making stuff up πŸ™ˆ
