that's it. that's the whole vibe. one argument, one int coming back at you π«Ά
π¦ DESCRIPTION π¦
So what does it actually do? It resumes the firmware and does hw init on the VCN block. That's the whole thing. No cap π
Like, the block was snoozing and now it's back, firmware resumed, hardware initialized, main character energy restored π
β ARGUMENTS β
ip_blockβ a pointer to theamdgpu_ip_blockfor this hw instance. literally just a pointer to the ip block for the hardware instance you're working with, nothing more, nothing less π§

ok that's the whole page bestie, go resume some firmware responsibly π
and a lil sign-off for the credits, because we always give credit π: this one lives at ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and it's page vcn_v2_5_resume(9). periodt π
