✨ zynqmp_pm_sha_hash(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 — this one's all about zynqmp_pm_sha_hash, the little function that lets you slide into the SHA engine's DMs and get your hash calculated. let's go 🎀

🌸 NAME 🌸

zynqmp_pm_sha_hash — get access to the SHA engine so it can calculate the hash for you, no cap 🧚

🦋 SYNOPSIS 🦋

int zynqmp_pm_sha_hash (const u64 address , const u32 size , const u32
flags );

like, that's the whole signature, copy it exactly bestie 💅

💜 ARGUMENTS 💜

  • address — the address of the data, or the address of the output buffer where the hash should be stored. yeah, it's giving dual-purpose main character energy 😭 which one it is depends on your flags, iykyk.
  • size — the size of the data fr fr.
  • flags — ok this one's the whole vibe, so listen up 👑:
    • BIT(0) — initializes the csudma driver and SHA3. lowkey iconic detail: with this one, the address and size inputs can be NULL 🫶.
    • BIT(1) — calls the Sha3_Update API. this is the one you can call multiple times when your data isn't contiguous — spread out data can still slay ✨.
    • BIT(2) — gets the final hash of the whole updated data. heads up though: the hash will be overwritten at the provided address with 48 bytes 💀 so don't be surprised.

🔥 RETURN 🔥

Returns status, either success or error code. that's it, that's the tea ☕
