💅 rproc_of_res...m_entry_init(9) 💅

okay so this is a page from the Kernel API Manual — yes the actual kernel manual, and yes we're gonna make it make sense. bestie, this one's about grabbing a reserved-memory phandle and turning it into a shiny rproc_mem_entry struct. lowkey iconic.

✨ NAME ✨

rproc_of_resm_mem_entry_init — allocate and initialize an rproc_mem_entry struct from a reserved memory phandle

like. that's the whole vibe. you point it at a reserved memory region, it hands you back a struct. no cap.

🫶 SYNOPSIS 🫶

struct rproc_mem_entry * rproc_of_resm_mem_entry_init (struct device
       *dev , u32 of_resm_idx , size_t len , u32 da , const char *name , ... );

look at her. five named args and then the ... just vibing at the end. main character energy fr.

🌸 ARGUMENTS 🌸

  • dev — pointer on device struct. the device you're doing all this for 🎀
  • of_resm_idx — reserved memory phandle index in "memory-region". yep, that's the exact string, index into it ✨
  • len — memory carveout length. how much space we're carving out 🍓
  • da — device address. the address as the device sees it 💜
  • name — carveout name. give her a name, she deserves one 👑
  • ... — variable arguments. mysterious. we love that for her 🙈

🦋 DESCRIPTION 🦋

so what she actually does: this function allocates a rproc_mem_entry struct and fills it with the parameters provided by the client. that's it. that's the tea ☕✨

allocate, fill, done. everything you passed in goes straight in there.

🔥 RETURN 🔥

a valid pointer on success, or NULL on failure. so like — check it, bestie 😭 don't just assume she slayed, do the vibe check.

no ERR_PTR here, just plain NULL on failure. handle it or perish 💀

🌈 SEE ALSO 🌈

she does not exist in a vacuum, she's part of a whole friend group:

and that's the page!! 🎀 she lives in ./drivers/remoteproc, dated October 2026, and the whole thing is filed under rproc_of_res...m_entry_init(9) in the Kernel API Manual. go build something, bestie, you got this 💖✨🦋
