cper_print_bits(9)

✨ cper_print_bits ✨

okay so this is a page from the Kernel API Manual (section 9, bestie, kernel dev vibes only) and it's about cper_print_bits — literally the function that prints strings for set bits 💅

---

🌸 NAME 🌸

cper_print_bits — print strings for set bits. that's it. that's the whole job. iconic honestly 🎀

---

🦋 SYNOPSIS 🦋

void cper_print_bits (const char *pfx , unsigned int bits , const char *
const strs[] , unsigned int strs_size );

no cap, that's the whole signature — copy it exactly when you use it, don't get creative 🙈

---

💖 ARGUMENTS 💖

• pfx — the prefix for each line, and yes that includes the log level and the prefix string. it's giving "every line gets a little name tag" 🏷️
• bits — the bit mask. this is the star of the show, the main character energy mask ⭐
• strs — the string array, indexed by bit position. so bit position N, string N. matchy matchy 🎀
• strs_size — the size of the string array, aka strs. just so we know how far the vibes go 🫶

---

🔥 DESCRIPTION 🔥

so here's the tea ☕ — for each set bit in bits, it prints the corresponding string from strs. literally one string per set bit, no extras, we love a predictable queen 👑

and if the output length is longer than 80, multiple lines get printed — and pfx gets printed at the beginning of each line. so like, every line stays branded. consistent branding era 💅✨

ngl, the 80 is the line-length vibe check — go over it and you get wrapped, and pfx shows up again at the start of every wrapped line. that's just how it is, bestie 🦋

okay bestie, that's the whole page 🎀 this one's a Kernel API Manual classic and it lives under ./drivers/firmware/efi, dated October 2026 — so yeah, mark your calendar and hydrate before you dig into that .c file 🌈💖🫶
