okay bestie, welcome to the Kernel API Manual — this page is intel_pmc_gcr_read64(9), and it's giving “read one 64-bit PMC GCR register” energy ✨

🌸 NAME 🌸

intel_pmc_gcr_read64 — Read a 64-bit PMC GCR register 💅

✨ SYNOPSIS ✨

int intel_pmc_gcr_read64 (struct intel_pmc_dev *pmc , u32 offset , u64 *data );

🎀 ARGUMENTS 🎀

• pmc — PMC device pointer. Like, the PMC device pointer, bestie 🫶
• offset — offset of GCR register from GCR address base. Exact vibe: where the GCR register sits relative to the GCR address base 🌈
• data — data pointer for storing the register output. It's the spot where the register output gets stored 💾

💖 DESCRIPTION 💖

Reads the 64-bit PMC GCR register at the given offset. That's it, that's the whole flex — you give it an offset, it reads the 64-bit PMC GCR register there, no cap 🔥

⭐ RETURN ⭐

Negative value on error, or 0 on success. So: error = negative 😭, success = 0 👑
