okay so this is the Kernel API Manual page for queue_wake_up_all(9) — the “handles fatal error case” bestie in the genwqe cinematic universe. 🎬💅

💖 NAME 💖

queue_wake_up_all — handles fatal error case. That’s it, that’s the assignment. 🚨

🌸 SYNOPSIS 🌸

int queue_wake_up_all (struct genwqe_dev *cd );

🎀 ARGUMENTS 🎀

• cd — pointer to genwqe device descriptor. Hand this over, bestie. 🫶

🦋 DESCRIPTION 🦋

Okay so scenario: the PCI device got unusable 😭 and we have to stop all pending requests as fast as we can. Like, as fast as we can, no cap — this is not the moment for a lil snack break. ⚡

The code after this must purge the DDCBs in question and ensure that all mappings are freed. That’s the whole vibe: purge the DDCBs in question, and make sure all mappings are freed. Periodt. 💅
