ps2_interrupt(9)

📦 version 7.3.1, in nixpkgs unstable

✨ ps2_interrupt(9) — like, the group chat for PS/2 devices 💖

okay so bestie, welcome to the Kernel API Manual entry for ps2_interrupt, and honestly? she's the main character of PS/2 interrupts. no cap. let's get into it 💅

🎀 NAME 🎀

ps2_interrupt — the common interrupt handler for PS/2 devices. one handler to rule them all, fr fr. 👑

🌸 SYNOPSIS 🌸

irqreturn_t ps2_interrupt (struct serio *serio , u8 data , unsigned int
flags );

like, that's the whole vibe. three params, one job. ✨

🦋 ARGUMENTS 🦋

  • serio — the serio port for the device. it's giving "this is whose data we're handling" energy 🫶
  • data — a data byte received from the device. one (1) single byte, and she matters 😭
  • flags — flags such as SERIO_PARITY or SERIO_TIMEOUT indicating state of the data transfer. lowkey important, these tell you what mood the transfer was in 💀

🔥 DESCRIPTION 🔥

so ps2_interrupt is out here doing the most, in the best way. she invokes the pre-receive handler, optionally handles the command acknowledgement and response from the device, and finally passes the data to the main protocol handler for future processing.

basically: prep, handle the receipt moment, hand it off. iconic three-step routine, honestly. ate and left no crumbs 🍓✨
