spu2_hash_xlate(9)

🌸 NAME 🌸

Okay so bestie, this is spu2_hash_xlate(9) from the Kernel API Manual — a total main-character little function. Its whole job: convert a hash {alg/mode/type} triple to a SPU2 hash type and mode. That’s the vibe. ✨

🎀 SYNOPSIS 🎀

Here’s the signature, untouched and iconic:

int spu2_hash_xlate (enum hash_alg hash_alg , enum hash_mode hash_mode ,
       enum hash_type hash_type , enum spu_cipher_type ciph_type , enum
       spu2_hash_type *spu2_type , enum spu2_hash_mode *spu2_mode );

💅 ARGUMENTS 💅

• hash_alg [in] — hash algorithm value from software enumeration. It’s giving “tell me which algorithm, bestie.”
• hash_mode [in] — hash mode value from software enumeration. The mode, as software sees it.
• hash_type [in] — hash type value from software enumeration. Yes, type. We love a specific triple.
• ciph_type [in] — cipher type value from software enumeration. Cipher type is riding along too.
• spu2_type [out] — hash type value used by SPU2 hardware. This is the glow-up output moment.
• spu2_mode [out] — hash mode value used by SPU2 hardware. And this is the matching hardware-mode output.

⭐ RETURN ⭐

0 if successful. That’s it — that’s the whole listed return. No extra lore, no invented error codes. 💖
