vcn_v5_0_2_mc_resume β Kernel API Manual β¨
okay so bestie, welcome to the glow-up era of this lil kernel function π«Ά. This page lives in the Kernel API Manual, and the star of the show is vcn_v5_0_2_mc_resume(9) β yes that's the whole name, she's not shortening it for anyone π
πΈ NAME πΈ
vcn_v5_0_2_mc_resume β memory controller programming, bestie. that's the gig π
β¨ SYNOPSIS β¨
void vcn_v5_0_2_mc_resume (struct amdgpu_vcn_inst *vinst );
literally one function, takes one arg, returns nothing. lowkey elegant, ngl π
π ARGUMENTS π
vinstβ the VCN instance. that's it, that's the whole parameter, she only needs one thing and she knows exactly what it is πΈ
π¦ DESCRIPTION π¦
so what does she do? the manual is out here saying, and we quote: let the VCN memory controller know it's offsets. yes, that's the entire description, and no we are not elaborating, because the original did not elaborate π. it's a resume for the memory controller β the whole vibe is telling the MC where its offsets live, periodt. no cap, that's the function. she's tiny but she's main character energy in the resume path π₯
