STRUCT DTHE_AES_REQ_CTX(9)

🌸 NAME 🌸

okay so bestie, welcome to the Kernel API Manual entry for struct dthe_aes_req_ctx — literally the AES engine req ctx struct 💅 that's the whole name, that's the whole vibe, and yes it's a struct in the kernel API docs, iykyk. fr fr this is the little bundle of state the DTHEv2 AES engine carries around per request 🎀

✨ SYNOPSIS ✨

not me just dropping the whole struct, character for character, because you need it exactly like this 🫶

struct dthe_aes_req_ctx {
    int enc;
    u8 padding[2 * AES_BLOCK_SIZE];
    struct completion aes_compl;
 };

🧚 Members 🧚

okay so let's do a vibe check on every single field, no skipping, we don't do that here 💖

• enc — this is the flag telling you whether we're doing an encryption or a decryption operation. that's it, that's the flag. lowkey iconic 🌈
• padding — a padding buffer whose whole job is handling unaligned data 🎀 yes it's there for the messy unaligned stuff, it's doing the lord's work tbh.
• aes_compl — the Completion variable, there for when you need to do a manual completion in case of a DMA callback failure 😭 like if the DMA callback ghosts you, this is the thing that says "it's done bestie". highkey important.
