okay so bestie, welcome to the Kernel API Manual β¨ β yes, we're reading kernel docs together, this is our bonding time, no cap. today's main character is vcn_v5_0_2_mc_resume_dpg_mode, and honestly? iconic of her.
πΈ NAME πΈ
vcn_v5_0_2_mc_resume_dpg_mode β literally the memory controller programming for dpg mode π
β¨ SYNOPSIS β¨
void vcn_v5_0_2_mc_resume_dpg_mode (struct amdgpu_vcn_inst *vinst , bool
indirect );
that's it. that's the whole vibe check. one function, two args, void return, she's not giving anything back and that's valid π
π¦ ARGUMENTS π¦
vinstβ the VCN instance, aka who we're talking about, like tagging someone in the group chat π«Άindirectβ write sram indirectly, iykyk. it's abool, so true or false, pick your fighter β¨
π DESCRIPTION π
so what she actually does? she lets the VCN memory controller know it's offsets with dpg mode. that's the whole thing. she's the messenger, she delivers the offsets, the memory controller says "periodt, noted" π
no extra lore, no secret side quests β just offset delivery with main character energy π

one more thing bestie π¨: she lives in ./drivers/gpu/drm/amd/amdgpu, and this lil page is dated October 2026. write that down. put it in your notes app. π
anyway that's the teardown, you ate that, go read the other 24 pages now πβ¨π
