AMDGPU RAP DEBUGFS TEST INTERFACE(9)

💅 AMDGPU RAP debugfs test interface

okay bestie, welcome to the Kernel API Manual ✨ this one's a lil baby page but it's still iconic, so pay attention 🫶

🌸 NAME

AMDGPU RAP debugfs test interface — literally the whole vibe of this page, no notes 💖

---

✨ DESCRIPTION ✨

so you wanna know how to use it? it's giving one-liner energy, honestly 👑

echo opcode > <debugfs_dir>/dri/xxx/rap_test

that's it. that's the whole ritual 🎀 you echo an opcode into <debugfs_dir>/dri/xxx/rap_test and the kernel handles the rest, slay ✨

🔥 the opcode tea

• opcode — currently, only 2 is supported by the Linux host driver 😌 (yes, just the one. she's exclusive 💅)

and what does 2 mean, you ask? so glad you did 🧚

• 2 — stands for TA_CMD_RAP__VALIDATE_L0 ⭐ it's the one that's used to trigger L0 policy validation. main character behaviour, fr fr 👑

want more deets? you can refer to more detail from the header file ta_rap_if.h 📄 iykyk 🌈

ngl bestie, don't go inventing new opcodes — only 2 is supported by the Linux host driver, and that's the whole menu 🍓
