ps3_vuart_write(9)

okay so welcome to ps3_vuart_write(9) — yes bestie, that's the title, and this page lives in the Kernel API Manual 💅

✨ NAME ✨

ps3_vuart_write — the entry point for writing data to a port. That's the whole name vibe, periodt 🎀

💖 SYNOPSIS 💖

int ps3_vuart_write (struct ps3_system_bus_device *dev , const void *buf
       , unsigned int bytes );

🎀 ARGUMENTS 🎀

• dev — the actual struct ps3_system_bus_device instance, no cap 👑
• buf — the manpage literally says -- undescribed -- 😭 so we're not inventing lore here, bestie
• bytes — same situation: -- undescribed -- 🙈 that's all the source gives us

🦋 DESCRIPTION 🦋

okay so here's the vibe check: if the port is idle on entry, as much of the incoming data is written to the port as the port will accept. slay ✨

otherwise, a list buffer is created and any remaining incoming data is copied to that buffer. then the buffer is enqueued for transmission via the transmit interrupt. that's the flow, fr fr 💜
