okay so bestie, welcome to the Kernel API Manual — section 9, kernel API, we love to see it 💅 this little page is all about scp_mapping_dm_addr, and honestly? she's a glow-up for your memory addresses 🫶

---

🎀 NAME 🎀

scp_mapping_dm_addr — literally mapping SRAM/DRAM to kernel virtual address, that's the whole gig ✨

---

🌸 SYNOPSIS 🌸

void * scp_mapping_dm_addr (struct mtk_scp *scp , u32 mem_addr );

---

🦋 ARGUMENTS 🦋

• scp — your mtk_scp structure, the main character of this whole function ngl 💖
• mem_addr — the SCP views memory address, like the address as the SCP sees it 👀

---

💜 DESCRIPTION 💜

So what she does is: she maps the SCP's SRAM address / DMEM (Data Extended Memory) memory address / Working buffer memory address over to a kernel virtual address 🧚✨ three different flavors of address, one slay little mapping, periodt.

---

🔥 RETURN 🔥

Returns ERR_PTR(-EINVAL) if the mapping failed 😭 otherwise you get the mapped kernel virtual address back, iconic 🙈💅
