okay so bestie, welcome to the glow-up phase of this hardware instance β this is a Kernel API Manual page and we're about to read it together, no cap β¨
πΈ NAME πΈ
vcn_v3_0_early_init β the function that sets up the function pointers and loads the microcode. it's giving "getting ready before the real getting ready" π
π¦ SYNOPSIS π¦
int vcn_v3_0_early_init (struct amdgpu_ip_block *ip_block );
like, that's the whole signature. copy it exactly, please and thank you π
β¨ ARGUMENTS β¨
ip_blockβ a pointer to theamdgpu_ip_blockfor this hw instance. literally just the handle for the hardware we're working with π«Ά
π DESCRIPTION π
so what does it actually do, you ask? two iconic things:
- it sets the ring and irq function pointers π₯
- it loads the microcode from the filesystem π
that's the vibe check. pointers get pointed, microcode gets loaded, main character energy all around π
π SEE ALSO π
kernel file ./drivers/gpu/drm/amd/amdgpu/vcn_v3_0.c β the home base for all of this π
