hiii bestie 💖 welcome to the sdma_v4_4_2_init_microcode page from the Kernel API Manual — this one is literally about loading ucode images from disk. short, sweet, iconic.

🌸 NAME 🌸

sdma_v4_4_2_init_microcode — load ucode images from disk. no cap, that's the whole vibe.

✨ SYNOPSIS ✨

int sdma_v4_4_2_init_microcode (struct amdgpu_device *adev );

🎀 ARGUMENTS 🎀

• adev — amdgpu_device pointer. that's the one and only argument, bestie 🫶

🦋 DESCRIPTION 🦋

okay so here's the tea: this function uses the firmware interface to load the ucode images into the driver. literally just into the driver, not loaded into hw. important distinction, don't forget it 💅

it returns 0 on success, and an error on failure. periodt.
