vmmouse_process_byte(9)

💖 vmmouse_process_byte — like, the whole vibe 💖

okay so bestie, welcome to the Kernel API Manual entry for vmmouse_process_byte ✨ this is a <pink>section 9</pink> situation, aka kernel internals, aka we're in the mouse driver and we're thriving 🐭💅

---

🌸 NAME 🌸

vmmouse_process_byte — process data on the ps/2 channel 🎀 lowkey the whole job description right there

---

✨ SYNOPSIS ✨

psmouse_ret_t vmmouse_process_byte (struct psmouse *psmouse );

that's it, that's the signature, no cap 🫶

---

🎯 ARGUMENTS 🎯

• psmouse — a pointer to the struct psmouse, literally just a pointer to the psmouse struct, that's the whole thing 🦋

---

💫 DESCRIPTION 💫

so here's the tea ☕ — when the ps/2 channel is like "hey girl, there's vmmouse data available," you call the vmmouse channel processing. <hotpink>periodt.</hotpink> otherwise? you just keep accepting bytes, business as usual, no drama 🌈

but 🚨 if there's a synchronization error or a communication data error, you return PSMOUSE_BAD_DATA — and the reason is literally in the hope that the caller will reset the mouse 🙏 like you're throwing the error up the chain and praying someone hits the reset button 😭

fr fr, that's the whole safety net: you flag it bad, you hope the caller resets. no guarantees, just vibes and a return code 💀
