RAS_MASK (UINT)(9)

💅 ras_mask (uint) 💅

okay bestie, welcome to the Kernel API Manual — this page is literally the whole ras_mask (uint) entry and it's short and sweet, so let's go ✨

---

🎀 NAME 🎀

ras_mask (uint) — the mask of RAS features to enable 🩺

---

💖 DESCRIPTION 💖

so ras_mask is a uint, and it's the mask of RAS features to enable. the default is 0xffffffff — yeah, all the bits, she's generous with it 💅

⚠️ real talk though: this is only valid when ras_enable == 1. if ras_enable isn't 1, this whole mask is lowkey doing nothing, no cap.

and the actual flags? go look at them in drivers/gpu/drm/amd/amdgpu/amdgpu_ras.h — that's where they live, i'm not inventing them 🫶

that's the whole page, bestie — she's a short one but she ate 💅✨

sign-off szn 🎀: this one lives in ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and it's the ras_mask (uint)(9) page of the Kernel API Manual. mwah, drink water, go check your flags 🦋💖
