rproc_mem_entry_init(9)

💖 rproc_mem_entry_init(9) — the glow-up edition 💖

okay so this is a page from the Kernel API Manual, and bestie, it's literally about making a rproc_mem_entry struct exist and look cute. buckle up 🎀

---

✨ NAME ✨

rproc_mem_entry_init — allocate and initialize rproc_mem_entry struct 🦋

---

🌸 SYNOPSIS 🌸

struct rproc_mem_entry * rproc_mem_entry_init (struct device *dev ,
       void *va , dma_addr_t dma , size_t len , u32 da , int (*alloc)(struct
       rproc *, struct rproc_mem_entry *) , int (*release)(struct rproc *,
       struct rproc_mem_entry *) , const char *name , ... );

like, look at that signature. it's giving long. it's giving function pointer energy. we love her tho 💅

---

🫶 ARGUMENTS 🫶

okay here's the whole cast, main character energy only:

• dev — pointer on device struct. the device we're doing all this for ✨
• va — virtual address. the vibe address, basically 🌈
• dma — dma address. yes it's a dma_addr_t, yes it matters 💜
• len — memory carveout length. how much room we're carving out, periodt 🎀
• alloc — memory carveout allocation function. the callback that actually does the allocating 🔥
• release — memory carveout release function. the callback that lets it go 😭
• name — carveout name. give her a name, she deserves one 👑
• ... — variable arguments. surprise guests, iykyk 🙈

---

💀 DESCRIPTION 💀

so what does this function even do? bestie. it allocates a rproc_mem_entry struct and then fills it with parameters provided by client. that's it. that's the whole thing. allocate + fill, no cap ✨

like, it's not out here doing magic tricks, it's just building you the struct you asked for with all the args you handed it. simple. iconic. ate. 💅

---

⭐ RETURN ⭐

a valid pointer on success, or NULL on failure 🫶

like — check it, okay? NULL is not a vibe, it means something went sideways 😭

ngl the manpage really said "This function allocates a rproc_mem_entry struct and fill it with parameters provided by client" and honestly? same energy. we love a humble queen 💖

---

💖 that's the whole page!! 💖 written from ./drivers/remoteproc, dated October 2026, and yeah the header up top said rproc_mem_entry_init(9) too — it's consistent, we stan. mwah, bye bestie 🫶✨🎀
