💖 vcn_v3_0_sw_init(9) 💖

okay so bestie, we're in the Kernel API Manual today, and the main character is vcn_v3_0_sw_init — the software-init girlie for the VCN block. she's lowkey the one who gets things loaded before anything else can pop off ✨

---

🌸 NAME 🌸

vcn_v3_0_sw_init — sw init for VCN block, no cap 🫶

---

🎀 SYNOPSIS 🎀

int vcn_v3_0_sw_init (struct amdgpu_ip_block *ip_block );

like... she takes exactly one argument and gives you back an int. that's it. that's the whole vibe check 💅

---

🦋 ARGUMENTS 🦋

• ip_block — a pointer to the struct amdgpu_ip_block for this hw instance. like, the specific hardware instance we're doing the sw init for, iykyk 👑

---

⭐ DESCRIPTION ⭐

Load firmware and sw initialization. that's literally the whole job description — she loads the firmware and does the sw initialization, and honestly? iconic. she's the setup era before the hardware era, and we respect the grind 🔥

ngl bestie, this is the "get your life together before the party" phase of the driver. firmware loaded, software sorted. periodt.
