pseries_eeh_..._config_addr(9)

📦 version 7.3.1, in nixpkgs unstable

Hiii bestie 💖 welcome to the Kernel API Manual page for pseries_eeh_..._config_addr(9) — we're about to make pe_config_addr make sense, no cap.

🌸 NAME 🌸

pseries_eeh_get_pe_config_addr — Find the pe_config_addr for a device. 💅

✨ SYNOPSIS ✨

int pseries_eeh_get_pe_config_addr (struct pci_dn *pdn );

🎀 ARGUMENTS 🎀

  • pdn — the pci_dn of the input device. That's the thing you're handing over, bestie 🫶

🦋 DESCRIPTION 🦋

Okay so picture this: the EEH RTAS calls use a tuple as a handle to a given PE. The tuple is literally:

(buid_hi, buid_lo, pe_config_addr)

This function finds the pe_config_addr based on the device's config addr. Iconic behavior, honestly ✨

Important vibe check 🚨: keep in mind that the pe_config_addr might be numerically identical to the device's config addr, but the two are conceptually distinct. Like, same digits can still be different concepts — iykyk 💅

It returns the pe_config_addr, or a negative error code. That's the whole mood 🌈
