β¨ vcn_v4_0_3_sw_init β¨
okay so we're in the Kernel API Manual bestie, and this is the page for vcn_v4_0_3_sw_init β the sw init for the VCN block π
no cap, that's literally the whole vibe of this page and it ate.
πΈ NAME πΈ
vcn_v4_0_3_sw_init β sw init for VCN block
like... it's the software-initialization entry point for this VCN block, and the name is giving exactly what it is π
π¦ SYNOPSIS π¦
int vcn_v4_0_3_sw_init (struct amdgpu_ip_block *ip_block );
she's an int-returning function, one argument, clean, iconic, periodt β¨
π ARGUMENTS π
ip_blockβ Pointer to thestruct amdgpu_ip_blockfor this hw instance. π«Ά that's your hw instance'samdgpu_ip_block, handed over as a pointer β you do NOT pass the whole struct, you pass the address, iykyk.
π₯ DESCRIPTION π₯
Load firmware and sw initialization π
fr fr that's the job: firmware gets loaded, and the software initialization happens. main character energy for the whole block, honestly π
heads up bestie β this page keeps it short on the details, so don't go inventing extra behavior and then blame me π everything you need to know for this one is right here π
π SEE ALSO π
the kernel file that's the actual source of truth lives at ./drivers/gpu/drm/amd/amdgpu/vcn_v4_0_3.c π go read her, she's iconic.

okay that's the page!! π§ from ./drivers/gpu/drm/amd/amdgpu, dated October 2026 β and yeah, vcn_v4_0_3_sw_init(9) is the one and only. bye bestie, go load some firmware π
