okay so bestie, welcome to the Kernel API Manual for r535_gsp_msg_run_cpu_sequencer(9) — yes the page title got chopped by the terminal gremlins into r535_gsp_msg...pu_sequencer(9), we don't ask questions, we just vibe 🫶

🌸 NAME 🌸

r535_gsp_msg_run_cpu_sequencer — literally processes I/O commands from the GSP. that's the whole job. main character energy fr 💅

int r535_gsp_msg_run_cpu_sequencer (void *priv , u32 fn , void *repv ,
       u32 repc );

that's the signature, copy it exactly, do not touch it, she is perfect 🎀

🦋 ARGUMENTS 🦋

• priv — the gsp pointer. that's it, that's the whole description, keep it moving 🏃‍♀️
• fn — the function number. and bestie… it's ignored. not me pointing that out but yeah, she's just there for the vibes 🙈
• repv — pointer to the libos print RPC 👑
• repc — the message size 📏

💜 DESCRIPTION 💜

okay so picture this: the GSP sequencer is a list of I/O commands that the GSP can send to the driver, so the driver can go do them for various purposes. she's a whole to-do list, lowkey ✨

and the most common usage? performing a special mid-initialization reset. iconic behaviour honestly, a little reset mid-init never hurt nobody 💅
