zpci_reset_...tore_blocked(9)

💖 NAME 💖

okay so we're flipping through the Kernel API Manual, and the page is zpci_reset_...tore_blocked(9). The function itself is zpci_reset_load_store_blocked — and it Re-enables L/S from error state. That's the whole name, bestie, no cap ✨

🌸 SYNOPSIS 🌸

int zpci_reset_load_store_blocked (struct zpci_dev *zdev );

🎀 ARGUMENTS 🎀

• zdev — the zdev for which to unblock load/store access. That's the argument, and honestly it's carrying the whole vibe 🫶

🦋 DESCRIPTION 🦋

So this one re-enables load/store access for a PCI function in the error state, while keeping DMA blocked. Yes, both things at once — highkey iconic 💅

In this state, drivers can poke MMIO space to determine if error recovery is possible, while catching any rogue DMA access from the device. It's giving "let them look, but don't let them touch" energy, fr fr 😭✨

👑 RETURN 👑

• 0 on success
• -EIO otherwise

Periodt. That's the return situation 💖
