vcn_v2_5_sw_fini(9)

📦 version 7.3.1, in nixpkgs unstable

✨ vcn_v2_5_sw_fini — the "okay we're done here" era ✨

So this is a page from the Kernel API Manual, section 9 (that's the kernel dev section bestie, iykyk), and it's all about vcn_v2_5_sw_fini. The name is literally "sw fini for VCN block" — fini like finished, like the French say fin, like when the group chat finally goes quiet at 2am. Lowkey iconic vibe.

✨ SYNOPSIS ✨

int vcn_v2_5_sw_fini (struct amdgpu_ip_block *ip_block );

It returns an int (yes, a whole int, she's got receipts) and takes exactly one argument. Periodt.

🎀 ARGUMENTS 🎀

  • ip_block — a pointer to the amdgpu_ip_block for this hw instance. Like, this specific one. The one you're holding. The main character of this hw instance, no cap. 🫶

💅 DESCRIPTION 💅

So here's the tea: VCN suspend and free up sw allocation. That's the whole thing. She suspends, she frees the sw allocation, she logs off. Highkey a productive queen. 💖

Not me reading this and going "oh so that's what sw fini means" — yes bestie, sw fini = software finalization, and she is doing it. 🌸

👑 SEE ALSO 👑

Okay so the canon lore first — this lives in the Kernel file:

./drivers/gpu/drm/amd/amdgpu/vcn_v2_5.c

And now the whole friend group, presented with love, in the original order, no skips, no merges (I would never 🙈):

Every single one present and accounted for. The get_rptr/set_wptr twins are literally the dec ring and enc ring girlies and they ate. 🔥

Friendly reminder bestie: vcn_v2_5_sw_fini exists to suspend and free up the sw allocation. Don't be out here inventing extra behaviour for her — she has one job and she's slaying it. 💀

Sign-off time, mwah 💋 — this page lives under ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and it's vcn_v2_5_sw_fini(9) forever and always. Go finish your software, queen. 🦋⭐🍓
