📦 version 7.3.1, in nixpkgs unstable

💅 sst_fill_and_send_cmd(9) — like, the Kernel API Manual page, bestie ✨

okay so real talk, this is a page from the Kernel API Manual (yes, that one, the sst_fill_and_send_cmd(9) girlies know) and it's literally about building an IPC message and yeeting it over to the FW. no cap, that's the whole vibe.

🎀 NAME 🎀

sst_fill_and_send_cmd — generate the IPC message and send it to the FW. that's it. that's the function. she builds it, she sends it, she slays 💅

✨ SYNOPSIS ✨

int sst_fill_and_send_cmd (struct sst_data *drv , u8 ipc_msg , u8 block
, u8 task_id , u8 pipe_id , void *cmd_data , u16 len );

like, seven arguments, one int return, main character energy fr fr 🌈

🌸 ARGUMENTS 🌸

  • drv — sst_data. the driver context, she's the whole personality of this call 🫶
  • ipc_msg — the type of IPC, and it's one of CMD, SET_PARAMS, or GET_PARAMS. pick your fighter 💖
  • block — block index. yes, an index. very demure, very mindful ⭐
  • task_id — task index. another index, she's thriving 🦋
  • pipe_id — pipe index. the third index, iconic honestly 👑
  • cmd_data — the IPC payload. this is the actual data going in, the moment 🍓
