💖 fm10k_iov_msg_msix_pf(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes, this whole page lives in the kernel API manual and it's about exactly one (1) function, and we're gonna read it together like it's the group chat 💅

🌸 NAME 🌸

fm10k_iov_msg_msix_pf — the message handler for MSI-X requests coming from a VF, periodt ✨

🎀 SYNOPSIS 🎀

s32 fm10k_iov_msg_msix_pf (struct fm10k_hw *hw , u32 **results , struct
fm10k_mbx_info *mbx );

that's the whole signature, no cap 🫶

🦋 ARGUMENTS 🦋

  • hw — pointer to the hardware structure, like the actual physical hardware vibes 💖
  • results — pointer array to the message, and heads up: results[0] is the pointer to the message 👑
  • mbx — pointer to the mailbox information structure, the mail slot of it all 📬

✨ DESCRIPTION ✨

so this function is the default handler for MSI-X requests from the VF — like, when nobody special has claimed the job, this is who picks up the phone 🙈

the assumption baked in here (and it's literally stated as an assumption, don't come for me) is that in this case it's acceptable to just directly hand off the message from the VF to the underlying shared code. no extra steps, no drama, just pass it along 💅 slay

💜 SEE ALSO 💜

first, the kernel file where this lives:

and then the whole extended family, because this function has so many siblings, iykyk:

like, that's the whole friend group, go read them too bestie 🧚

and that's the page!! mwah 💋

this cutie came from ./drivers/net/ethernet/intel/f... (the source is truncated like that in the original, not my fault 😭) and it's dated October 2026 — stamped with the manual name fm10k_iov_msg_msix_pf(9) at the bottom, iconic behavior honestly 🌈⭐
