📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to stm_ftrace_write(9) — that's the title, and the manual name is Kernel API Manual. this page is literally about writing data to STM via the 'stm_ftrace' source, and it's giving tiny-but-iconic kernel energy. 💅✨

💖 NAME 💖

stm_ftrace_write — write data to STM via 'stm_ftrace' source. 👑

✨ SYNOPSIS ✨

the signature is exactly this, character for character, no edits, periodt:

void notrace stm_ftrace_write (struct trace_export *export , const void
       *buf , unsigned int len );

it returns void, and notrace is right there in the signature — keep it exactly like that, bestie. 🫶

🎀 ARGUMENTS 🎀

  • export — the page literally says -- undescribed -- for this one, so no cap, we are not inventing lore. 💀
  • buf — buffer containing the data packet. 🌸
  • len — length of the data packet. ✨

🦋 SEE ALSO 🦋

  • Kernel file ./drivers/hwtracing/stm/ftrace.c 👑
