💖 elm_error_correction(9) — Kernel API Manual 💖

💖 NAME 💖

elm_error_correction — locate correctable error position. That’s the whole gig, bestie: it locates where the correctable error is at. ✨

🌸 SYNOPSIS 🌸

void elm_error_correction (struct elm_info *info , struct elm_errorvec
       *err_vec );

🫶 ARGUMENTS 🫶

• info — elm info. Like, the elm info, no cap.
• err_vec — elm error vectors. The error-vector squad. 🦋

💅 DESCRIPTION 💅

Okay so when the elm module finishes processing, the error location status register gets updated with correctable/uncorrectable error information. That’s the vibe check. 💀

If we’re in correctable-error territory, the number of errors gets located from the elm location status register & the positions get read from the elm error location register. Literally reading the positions, periodt. 🔥
