vcn_v4_0_3_hw_init(9)

💖 NAME 💖

okay so bestie, this is the Kernel API Manual page for vcn_v4_0_3_hw_init(9) 💅 and its whole gig is to start and test VCN block — iconic, lowkey essential, no cap ✨.

🌸 SYNOPSIS 🌸

the signature, verbatim, because we do not mess with the code bestie:

int vcn_v4_0_3_hw_init (struct amdgpu_ip_block *ip_block );

🦋 ARGUMENTS 🦋

• ip_block — a pointer to the amdgpu_ip_block for this hw instance. that's the exact thing it wants 🫶.

✨ DESCRIPTION ✨

so here's the vibe: it initializes the hardware, boots up the VCPU, and does some testing 🔥. that's it, that's the function — hardware go brrr, VCPU wakes up, tests happen, slay 💅.
