✨ NAME ✨

gmc_v8_0_gart_disable — literally just gart disable. that's the whole name, she's not subtle and honestly? iconic. 👑

🌸 SYNOPSIS 🌸

void gmc_v8_0_gart_disable (struct amdgpu_device *adev );

no return value, no cap. it takes exactly one thing and it handles its business. 💅

🦋 ARGUMENTS 🦋

• adev — an amdgpu_device pointer, that's it, that's the whole vibe. she needs her device pointer and then she's good to go 🫶

💖 DESCRIPTION 💖

so what does she do? this bad girl disables all VM page table (VI). all of it. every last bit. she's the cleanup crew, the "we're done here" text in the group chat, the closing credits. when the GART stuff needs to be turned off, this is the function that gets it done 😭🔥

that's genuinely the entire description. short, sweet, and to the point — she said what she said. periodt. ⭐
