💅 ixgbe_pcie_timeout_poll(9) — Kernel API Manual 🎀

okay bestie, so this is ixgbe_pcie_timeout_poll(9) from the Kernel API Manual, and it's literally the function that tells you how many times to keep poking at your PCIe stuff before you're allowed to give up. it's giving "patient friend energy" fr fr.

✨ NAME ✨

ixgbe_pcie_timeout_poll — Return number of times to poll for completion 💫

🌸 SYNOPSIS 🌸

u32 ixgbe_pcie_timeout_poll (struct ixgbe_hw *hw );

🦋 ARGUMENTS 🦋

  • hw — pointer to hardware structure. like, the whole hardware vibe, handed to you as a pointer 🫶

💖 DESCRIPTION 💖

so the system-wide timeout range is encoded in the PCIe Device Control2 register. that's where the tea lives, no cap.

what you do: add 10% to that specified maximum, then return the number of times to poll for completion timeout — measured in units of 100 microsec ⏱️.

and the absolute floor? never return less than 800 = 80 millisec 🙅‍♀️ like, that's the minimum, periodt. never less. don't even think about it.
