amdgpu_gfx_csb_data_parser(9)

✨ amdgpu_gfx_csb_data_parser ✨

okay bestie, welcome to the Kernel API Manual 💅 this one's a little function from the AMDGPU gfx world and honestly it's giving "small but crucial" energy 🎀

---

🌸 NAME 🌸

amdgpu_gfx_csb_data_parser — Parser CS data 🫶

---

🦋 SYNOPSIS 🦋

u32 amdgpu_gfx_csb_data_parser (struct amdgpu_device *adev , u32 *buffer
, u32 count );

---

💖 ARGUMENTS 💖

• adev — the amdgpu_device pointer, and no cap it's doing the heavy lifting here: it's what you use to get the CS data plus all the other gfx info 🧚
• buffer — okay so this one is an output variable, meaning it's not here to give you anything, it's here to receive: it gets the PACKET3 preamble end 👑
• count — the index you start from when setting the preemble end ⭐ (yes that's how it's spelled in the original, she's quirky, we love her)

---

🌈 RETURN 🌈

it returns the latest index 💫 that's it, that's the whole vibe check.
