ocs_create_l...list_from_sg(9)

🎀 NAME 🎀

okay so bestie, this is ocs_create_linked_list_from_sg — it's giving "Create OCS DMA linked list from SG list." that's the whole vibe. it's a (9) Kernel API Manual situation, and honestly? it ate. ✨

💫 SYNOPSIS 💫

int ocs_create_linked_list_from_sg (const struct ocs_aes_dev *aes_dev ,
struct scatterlist *sg , int sg_dma_count , struct ocs_dll_desc
*dll_desc , size_t data_size , size_t data_offset );

like literally just call it with those six things, no cap 🫶

---

🌸 ARGUMENTS 🌸

• aes_dev — the OCS AES device that the list is gonna be created for. it's her stage, her moment, main character energy fr.
• sg — the SG list that the OCS DMA linked list gets created from. ok so important detail bestie: when you pass sg to this function, it must have already been mapped with dma_map_sg. like it's not optional, don't skip that step 💅
• sg_dma_count — the number of DMA-mapped entries in sg. and this has to be exactly the value that dma_map_sg returned back when sg was mapped. no making up numbers, iykyk 🔥
• dll_desc — the OCS DMA dma_list you use to store info about the linked list that got created. it's the lil memory keeper 🎀
• data_size — the size of the data (from the SG list) that's being mapped into the OCS DMA linked list.
• data_offset — the offset (within the SG list) of the data that's being mapped.

⭐ RETURN ⭐

0 on success, and a negative error code if it's not. 😭 (so like, check it. please. for me.)

and that's the whole page bestie, mwah 💖 this little gem lives in ./drivers/crypto/intel/keembay, and the version she's serving is from October 2026 — go off, honestly. 🌈✨🍓
