📦 version 7.3.1, in nixpkgs unstable

💅 scmi_raw_mode_init — NAME

okay so like, welcome to the Kernel API Manual bestie, this is scmi_raw_mode_init(9) and it's literally the function that initializes the SCMI Raw stack ✨ no cap, that's the whole name, that's the whole vibe.

🎀 SYNOPSIS

void * scmi_raw_mode_init (const struct scmi_handle *handle , struct
dentry *top_dentry , int instance_id , u8 *channels , int num_chans ,
const struct scmi_desc *desc , int tx_max_msg );

she takes a bunch of args and hands you back a void * — iconic signature tbh 🫶

🌸 ARGUMENTS

okay so here's the roster, every single one of them, no skips:

  • handle — pointer to the SCMI entity handle. like, the main character reference 💫
  • top_dentry — a reference to the top Raw debugfs dentry. yes she lives in debugfs, we love that for her.
  • instance_id — the ID of the underlying SCMI platform instance that this Raw instance represents. iykyk 🪪
  • channels — the list of the existing channels. all of them. the whole lineup.
  • num_chans — the number of entries in channels. gotta know how many besties are in the group chat 💬
  • desc — reference to the transport operations. the plumbing, the mechanics, the ~structure~ 🔧
  • tx_max_msg — max number of in-flight messages allowed by the transport. like a vibe check on how much can be happening at once 🚦

🦋 DESCRIPTION

so what she actually does: this function prepares the SCMI Raw stack and creates the debugfs API. that's it, that's the job, and she ate 💅✨

🌈 RETURN

  • On success → an opaque handle to the Raw instance 👑 (don't peek inside, it's opaque, respect her privacy)
  • Otherwise → an ERR_PTR 😭 so yeah, check for errors fr fr
