💅 igc_read_nvm_srrd_i225(9) — a Kernel API Manual moment

okay so this is from the Kernel API Manual, section 9, and the star of the show is igc_read_nvm_srrd_i225. yes that's a lot of letters, no we're not renaming it, it's iconic as is 🎀

✨ NAME ✨

igc_read_nvm_srrd_i225 — literally just reads the Shadow Ram using the EERD register. that's the whole vibe. 🦋

🌸 SYNOPSIS 🌸

s32 igc_read_nvm_srrd_i225 (struct igc_hw *hw , u16 offset , u16 words ,
u16 *data );

like, four things in, an s32 out, and it's giving "trust the process" energy ngl 💜

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure, bestie. the whole hardware situation lives here 🫶
  • offset — offset of word in the Shadow Ram to read. where we're looking, basically 📍
  • words — number of words to read. plural, we're grabbing a few 👑
  • data — word read from the Shadow Ram. this is where the goods land ✨

🔥 DESCRIPTION 🔥

so the whole thing reads a 16 bit word from the Shadow Ram using the EERD register. 16 bits. tiny but mighty, periodt 💅

and — important — it uses the necessary synchronization semaphores. so it's being a responsible main character about concurrency, not just barging in 🙈

🦋 SEE ALSO 🦋

the kernel file lives at ./drivers/net/ethernet/intel/igc/igc_i225.c — that's the home base 🏠

and the whole friend group, all of them, no one gets left out:

ngl the _i225 suffix appearing like 14 times is a whole aesthetic. iykyk 💀
