__verify_ras_table_checksum(9)

🌸 __verify_ras_table_checksum 🌸

okay bestie, welcome to the Kernel API Manual — we're doing a little vibe check on a checksum today and honestly? it's giving "responsible adult energy" 💅

---

✨ NAME ✨

__verify_ras_table_checksum — verify the RAS EEPROM table checksum 🎀

like, the whole point. it checks the check. iconic.

---

🦋 SYNOPSIS 🦋

int __verify_ras_table_checksum(struct ras_eeprom_control *control);

---

🌸 ARGUMENTS 🌸

• control — pointer to control structure. that's it. that's the whole parameter. she's lowkey simple like that 🫶

---

💖 DESCRIPTION 💖

So here's the tea: this function checks the checksum of the RAS table that's stored in the EEPROM. no cap, that's literally the job. 🧚

It returns 0 if the checksum is correct, a positive value if it is not correct, and -errno on an I/O error.

ngl bestie, watch that return value — positive means "hmm, sus, checksum is off" and negative means "the I/O itself went wrong." two totally different problems, two totally different signs. don't mix them up 💀
