💅 mei_cl_irq_write(9) — from the Kernel API Manual, bestie ✨

okay so real talk, this one lives in the Kernel API Manual, section 9, and it's called mei_cl_irq_write. it's giving "write a message to the device, but from the interrupt thread context" energy, and honestly? iconic of it. let's get into it 🫶

🌸 NAME 🌸

mei_cl_irq_write — write a message to device from the interrupt thread context 💌

like... not from your cozy little process context, no ma'am. from the interrupt thread context. different vibe entirely, iykyk.

✨ SYNOPSIS ✨

int mei_cl_irq_write (struct mei_cl *cl , struct mei_cl_cb *cb , struct
       list_head *cmpl_list );

three args, returns an int, classic. look at her go 🔥

🎀 ARGUMENTS 🎀

  • cl — the client 💅 that's it, that's the whole description, she's a client and she's the main character here
  • cb — the callback block 🦋 yes bestie, the callback block
  • cmpl_list — the complete list 🌈 the list of things that are done-done

💖 RETURN 💖

0, OK; otherwise error. so like, zero means slay, anything else means something went sideways 😭 periodt.
