vcn_v4_0_dis...ing_dpg_mode(9)
π NAME
okay so bestie, let me introduce you to vcn_v4_0_disable_clock_gating_dpg_mode β like the whole vibe of this function is disable VCN clock gating dpg mode. that's it, that's the job. it turns the thing off. slay. β¨
this one lives in the Kernel API Manual btw, so you know it's legit π
π SYNOPSIS
void vcn_v4_0_disable_clock_gating_dpg_mode (struct amdgpu_vcn_inst
*vinst , uint8_t sram_sel , uint8_t indirect );
like literally that's the whole signature, no cap. it returns void because it's not here to give you answers, it's here to do the thing π
πΈ ARGUMENTS
vinstβ your VCN instance, the main character of this whole operation π«Άsram_selβ sram select, aka which sram we're talking about hereindirectβ indirectly write sram, so like, secondhand sram writing energy
π¦ DESCRIPTION
okay so the actual tea: this function disables clock gating for the VCN block with dpg mode. clock gating? off. dpg mode? that's the context. VCN block? that's the subject. periodt. πβ¨
that's genuinely it β no hidden lore, no plot twists, just a clean little disable call doing its one job beautifully. iconic behavior honestly π
