✨ gmc_v8_0_set_prt — set PRT VM fault ✨

okay bestie, so this is a kernel API manual page for gmc_v8_0_set_prt(9) (that's the manual name, iykyk — it's from the Kernel API Manual 💅) and honestly it's a tiny little function but she's doing Important Work. let's get into it 🫶

🌸 SYNOPSIS 🌸

void gmc_v8_0_set_prt (struct amdgpu_device *adev , bool enable );

like, that's the whole vibe. one function, two args, zero drama. no cap. ✨

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer. that's your amdgpu device right there, being pointed at. iconic behavior honestly 🦋
• enable — a bool that turns VM fault handling for PRT on or off. so basically: enable/disable VM fault handling for PRT. yes that's what it does, we love a self-explanatory king 👑

okay so here's the whole friend group, the Kernel file ./drivers/gpu/drm/amd/amdgpu/gmc_v8_0.c and all her siblings — go say hi, they're all literally so relevant:

bestie reminder: this page lives under ./drivers/gpu/drm/amd/amdgpu and it's dated October 2026 in the Kernel API Manual. that's the whole footer, and yeah we're mentioning it because it's part of the lore 💀💖

and that's the page!! short, sweet, absolutely ate, no crumbs left. mwah 💅🎀🌸
