srpt_alloc_ioctx(9)

💅 srpt_alloc_ioctx — like, the SRPT I/O context allocator bestie

okay so this is a page from the Kernel API Manual (manual section 9, srpt_alloc_ioctx(9)) and honestly? it's a little one but she's doing her job. let me put you on. 🫶

✨ NAME ✨

srpt_alloc_ioctx — allocate a SRPT I/O context structure

no cap, that's the whole pitch. she allocates. she's an I/O context. iconic behaviour. 👑

---

🌸 SYNOPSIS 🌸

struct srpt_ioctx * srpt_alloc_ioctx (struct srpt_device *sdev , int
ioctx_size , struct kmem_cache *buf_cache , enum dma_data_direction dir
);

like, she returns a struct srpt_ioctx * and she wants four things from you before she'll even look at you. main character energy fr. ✨

---

🎀 ARGUMENTS 🎀

• sdev — the SRPT HCA pointer. this is the hardware situation, she needs to know who she's working with 💖
• ioctx_size — the I/O context size. how much context, bestie. specify it.
• buf_cache — the I/O buffer cache. struct kmem_cache *, the cache she pulls buffers from 🦋
• dir — the DMA data direction. enum dma_data_direction, so she knows which way the data's flowing 🔥

ngl, get these four right or she's not gonna be the one. that's it, that's the whole argument list. short and slay.

and that's the page!! 💜 mwah 💋

cute little sign-off: this one lives out of ./drivers/infiniband/ulp/srpt, it's dated October 2026, and it's literally titled srpt_alloc_ioctx(9). periodt. 🌈⭐
