vcn_v4_0_3_suspend(9)

🌸 NAME 🌸

vcn_v4_0_3_suspend — okay so this one's whole job is: suspend the VCN block 💅 (this is from the Kernel API Manual, section 9, bestie — we're in kernel-functions land now 🧚)

✨ SYNOPSIS ✨

int vcn_v4_0_3_suspend (struct amdgpu_ip_block *ip_block );

That's it, that's the whole vibe check. Returns an int, takes one arg, slays. 🫶

🎀 ARGUMENTS 🎀

• ip_block — a pointer to the amdgpu_ip_block for this hw instance — like, this specific hardware's little passport, no cap. 🦋

💅 DESCRIPTION 💅

So basically: HW fini and suspend VCN block. That's the entire lore, fr fr — it does the hardware fini thing and the suspend thing on the VCN block, and then it's done. Iconic behavior honestly. ✨
