decode_mtr(9)

💅 decode_mtr(9) — the Kernel API Manual page, but make it make sense 🎀

okay bestie, so this one is from the Kernel API Manual and it's called decode_mtr(9) — say it with me: dee-code em-tee-arr, it's giving "gritty low-level hardware detective work" and honestly? iconic. ✨

---

🌸 NAME 🌸

decode_mtr — literally decodes the MTR descriptor and fills up the edac structs. that's the whole job. no cap. 🫶

---

✨ SYNOPSIS ✨

int decode_mtr (struct i7300_pvt *pvt , int slot , int ch , int branch ,
struct i7300_dimm_info *dinfo , struct dimm_info *dimm );

---

👑 ARGUMENTS 👑

okay so here's the cast of characters, and every single one of them matters, don't skip 💅

• pvt — pointer to the private data struct that the i7300 driver uses. it's the driver's little backstage pass. 🎟️
• slot — the DIMM slot, and it lives in the range 0 to 7. so eight possibilities, choose wisely. 🙈
• ch — channel number within the branch. it's either 0 or 1. binary baddie behavior. 🦋
• branch — branch number. also 0 or 1. yes it's another one, keep up bestie. ⭐
• dinfo — pointer to DIMM info where the dimm size gets stored. that's where the tea lives. 🍓
• dimm — pointer to the struct dimm_info that corresponds to that element. the matching piece, the pair, the duo. 💖
