gmc_v8_0_se...able_default(9)

💅 gmc_v8_0_set_fault_enable_default(9) — like, the whole glow-up

okay so bestie, welcome to the Kernel API Manual ✨ and buckle up because today's main character is gmc_v8_0_set_fault_enable_default. (Yeah the header up top truncates it to gmc_v8_0_se...able_default(9) — she's mysterious like that, but we know her full name and we're gonna use it 🎀)

🌸 NAME 🌸

gmc_v8_0_set_fault_enable_default — literally just updating VM fault handling, that's the whole vibe 💅

✨ SYNOPSIS ✨

void gmc_v8_0_set_fault_enable_default (struct amdgpu_device *adev ,
       bool value );

no cap, that's the entire signature, copy it exactly, don't @ me 🙈

🦋 ARGUMENTS 🦋

• adev — an amdgpu_device pointer. that's it, that's the descriptor. she's giving "was literally just described in one line" energy 💀
• value — a bool. when it's true, VM faults get redirected to the default page. like, faults go sit in the timeout chair instead of causing chaos 🔥👑
