✨ vcn_v5_0_0_disable_clock_gating_dpg_mode ✨

okay so bestie, welcome to the Kernel API Manual 💖 — this one's a lil function page from the AMDGPU VCN v5.0.0 squad, and honestly? she's a small function with a big job. no cap.

🎀 NAME 🎀

vcn_v5_0_0_disable_clock_gating_dpg_mode — literally turns OFF clock gating for VCN when it's vibing in dpg mode 💅

🌸 SYNOPSIS 🌸

void vcn_v5_0_0_disable_clock_gating_dpg_mode (struct amdgpu_vcn_inst
*vinst , uint8_t sram_sel , uint8_t indirect );

like, it returns void — nothing comes back, she just does the thing and leaves. main character energy fr fr ✨

🦋 ARGUMENTS 🦋

  • vinst — the VCN instance 🫶 which one are we talking to? this is her.
  • sram_sel — sram select. yeah, you gotta say which sram. pick one, bestie 🎀
  • indirect — indirectly write sram 👀 so the write goes in sideways, iykyk

💜 DESCRIPTION 💜

Disable clock gating for the VCN block with dpg mode 🌈 that's the whole plot. no plot twists. she disables it, she's done, and it's iconic.
