gmc_v11_0_mc_init(9)

🌸 NAME 🌸

gmc_v11_0_mc_init — initialize the memory controller driver params 💅

Okay so bestie, welcome to the Kernel API Manual page for gmc_v11_0_mc_init(9) — yes, section 9, we are in kernel API land, and this function is literally here to initialize the memory controller driver params. No cap. ✨

✨ SYNOPSIS ✨

int gmc_v11_0_mc_init (struct amdgpu_device *adev );

That’s the whole call, bestie. One argument, and it returns an int. 🫶

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer. That’s the GPU device handle this function is doing its thing with. 🦋

🦋 DESCRIPTION 🦋

So what does it actually do? It looks up the amount of vram, looks up the vram width, and then decides how to place vram and gart within the GPU’s physical address space. That’s the main character energy right there. ✨

And when it works? It returns 0 for success — slay. 💖
