okay so bestie, welcome to the Kernel API Manual ✨ this one's a lil function page and it's lowkey iconic, sit down, grab a strawberry πŸ“


🌸 NAME 🌸

sdma_v7_0_load_microcode β€” literally loads the sDMA ME ucode, that's the whole vibe πŸŽ€


✨ SYNOPSIS ✨

int sdma_v7_0_load_microcode (struct amdgpu_device *adev );

like. that's it. that's the whole signature. she's simple, she's clean, she slays πŸ’…


πŸ¦‹ ARGUMENTS πŸ¦‹

  • adev β€” a pointer to an amdgpu_device, so basically the whole GPU's main character energy gets passed in right here πŸ‘‘

πŸ’œ DESCRIPTION πŸ’œ

So what does she actually do? She loads the sDMA0/1 ucode β€” both instances, no cap, she's doing the absolute most in the best way πŸ’–

And the return values? Get this:

  • returns 0 when it's all good β€” success, slay, we ate πŸŽ‰
  • returns -EINVAL if the ucode is not available β€” like if the firmware just did not show up to the party 😭 not the ucode ghosting you 😭
fr fr, that's the whole contract. 0 = good vibes, -EINVAL = no ucode, nothing in between 🫢
