omap_rproc_da_to_va(9)

✨ omap_rproc_da_to_va ✨

Hey bestie, welcome to the omap_rproc_da_to_va(9) page from the Kernel API Manual 💅 — this is the internal memory translation helper, and honestly it's giving "quiet little function that keeps everything running" energy 🎀

---

🌸 SYNOPSIS 🌸

void * omap_rproc_da_to_va (struct rproc *rproc , u64 da , size_t len ,
       bool *is_iomem );

---

🫶 ARGUMENTS 🫶

• rproc — the remote processor you're doing the address translation for 👑
• da — the device address that needs translating, fr fr
• len — how long the memory buffer is 🌸
• is_iomem — a pointer that gets filled in to tell you whether da is iomapped memory 🦋

---

💖 DESCRIPTION 💖

Okay so this is a custom function implementing the rproc .da_to_va ops — iykyk — and its whole job is providing address translation (device address ➡️ kernel virtual address) for the internal RAMs present in a DSP or IPU device 😭✨

The translated addresses can be used either by the remoteproc core for loading, or by any rpmsg bus drivers 🧚 No cap, that's the whole vibe.

---

⭐ RETURN ⭐

On success you get the translated virtual address in kernel memory space 💜 On failure? NULL. That's it. Periodt 💀
