STRUCT CTX_HDR(9)

✨ struct ctx_hdr(9) ✨

okay bestie, so we're in the Kernel API Manual today and the star of the show is struct ctx_hdr — literally the bookkeeping data about the crypto context 🎀 like it's the little admin gremlin holding the receipts so the actual crypto work can slay 💅

---

💖 NAME 💖

struct ctx_hdr — book keeping data about the crypto context ✨

---

🦋 SYNOPSIS 🦋

struct ctx_hdr {
    struct dma_pool *pool;
    dma_addr_t dma;
    dma_addr_t ctx_dma;
 };

no cap, that's the whole vibe right there 👑

---

🌸 Members 🌸

• pool — the pool used to allocate the crypto context, like the little closet where the context lives 🎀
• dma — base DMA address of the crypto context, the address-address iykyk ✨
• ctx_dma — the actual usable crypto context for NITROX, the one that actually does the work 🔥
