💖 vcn_v5_0_0_mc_resume_dpg_mode (9) — Kernel API Manual 💖

okay bestie, so this is a page from the Kernel API Manual and it's all about one lil function in the AMDGPU VCN5.0.0 saga. it's giving "niche but iconic" ✨

🌸 NAME 🌸

vcn_v5_0_0_mc_resume_dpg_mode — memory controller programming for dpg mode 🎀

like, the whole vibe is: we're waking the memory controller back up, but specifically in dpg mode. iykyk 😌

✨ SYNOPSIS ✨

void vcn_v5_0_0_mc_resume_dpg_mode (struct amdgpu_vcn_inst *vinst , bool indirect );

that's it. that's the whole call. no return value (it's void, so nothing comes back — truly a "no thoughts, just vibes" function 💅).

🦋 ARGUMENTS 🦋

  • vinst — the VCN instance 💜 (the actual thing we're working on, bestie)
  • indirect — indirectly write sram ✍️ (a bool, so it's a simple yes/no on whether we do the sram writes the indirect way)

🎀 DESCRIPTION 🎀

so what does it actually do? it lets the VCN memory controller know its offsets — with dpg mode in the mix 🌈. that's the tea, that's the assignment. it is literally just informing the memory controller where things sit when dpg mode is on. periodt.

🔥 SEE ALSO 🔥

the source lives right here in the kernel tree, go look:

Kernel file ./drivers/gpu/drm/amd/amdgpu/vcn_v5_0_0.c

and here's the whole friend group (yes, all of them, no cap — not skipping a single one 👑):

💀 just a heads up bestie: no warnings, no bugs, no exit statuses on this page — it's a clean lil void function and the manpage keeps it that way. don't go reading extra lore into it, fr fr.

and that's the whole page, slay 🫶 this beauty came from the ./drivers/gpu/drm/amd/amdgpu source, dated October 2026, and it's page vcn_v5_0_0_...ume_dpg_mode(9) of the Kernel API Manual. mwah, go read some kernel code, you're doing amazing 💖✨🍓
