pci_vc_load_arb_table(9)

📦 version 7.3.1, in nixpkgs unstable

💅 pci_vc_load_arb_table(9) — from the Kernel API Manual ✨

okay bestie, welcome to the manual page for pci_vc_load_arb_table — yes it's a whole (9) section situation, we're in the big leagues now 🎀

🌸 NAME 🌸

pci_vc_load_arb_table — loads the VC arbitration table and then waits for it, because we're polite 👑 (no cap, the "wait" part is literally in the name, it's giving patience)

🦋 SYNOPSIS 🦋

void pci_vc_load_arb_table (struct pci_dev *dev , int pos );

like, that's the whole signature. void return, two args, she's compact 💜

✨ ARGUMENTS ✨

  • dev — the device. yeah. that's the device. the device in question 🫶
  • pos — the starting position of the VC capability (that's VC/VC9/MFVC, all three, iykyk)

💖 DESCRIPTION 💖

okay so here's the vibe: this function sets the Load VC Arbitration Table bit, which is basically you sliding into the hardware's DMs like "hey bestie, please apply the VC Arbitration Table" — specifically the one that was previously loaded, so not a fresh new one, an already-queued-up one 👀

and then the waiting part, which is the iconique bit: when the VC Arbitration Table Status clears, that means the hardware has officially latched the table into the VC arbitration logic. table delivered, table received, main character energy, periodt 🌈⭐

so like — set the bit, then vibe until the status clears. that's the whole ritual ✨

🔥 SEE ALSO 🔥

the kernel file ./drivers/pci/vc.c (yes the file, go look at it, it's right there) and also these absolute legends:

🫶 that's the whole page bestie, go forth and load those arbitration tables responsibly 💅

cute little sign-off: this one came out of ./drivers/pci and it's dated October 2026 — mwah, see u in the next one 😭💖
