📦 version 7.3.1, in nixpkgs unstable

🌸 t4_cim_read_la — read CIM LA capture buffer 🌸

okay so bestie, welcome to t4_cim_read_la(9), straight out of the Kernel API Manual. this one's a little function with a big job: it yoinks the CIM LA capture buffer contents out for you. let's get into it 💅

✨ NAME ✨

t4_cim_read_la — read CIM LA capture buffer 🎀

✨ SYNOPSIS ✨

int t4_cim_read_la (struct adapter *adap , u32 *la_buf , unsigned int
*wrptr );

like, three args, one int back. slay.

✨ ARGUMENTS ✨

  • adap — the adapter 💖 that's your whole device vibe right there
  • la_buf — where to store the LA data 🫶 this is the lil home for everything we pull out
  • wrptr — the HW write pointer within the capture buffer ⭐ keep your eyes on this one, it decides what comes out first

✨ DESCRIPTION ✨

so here's the tea ☕ — t4_cim_read_la reads the contents of the CIM LA buffer. and the ordering is very much on purpose, no cap: the most recent entry lands at the end of the returned data, and the entry sitting at wrptr comes out first 👑

also, we're polite about it — we try to leave the LA in the running state we found it in. not me respecting the hardware's boundaries 😭🫶
