amdgpu_device_wreg(9)

💖 NAME 💖

okay bestie, this is amdgpu_device_wreg(9) from the Kernel API Manual ✨ — its whole thing is: write to a memory mapped IO or indirect register. That's the assignment, no cap 💅.

✨ SYNOPSIS ✨

void amdgpu_device_wreg (struct amdgpu_device *adev , uint32_t reg ,
uint32_t v , uint32_t acc_flags );

🎀 ARGUMENTS 🎀

• adev — amdgpu_device pointer 🫶
• reg — dword aligned register offset, periodt.
• v — 32 bit value to write to the register 💖
• acc_flags — access flags which require special behavior ⚠️

🌸 DESCRIPTION 🌸

Writes the value specified to the offset specified. That's it, that's the function — it takes the value and drops it at that offset, iconic behavior only 💅✨.
