xe_reg_dewhitelist_oa_regs(9)

💅 xe_reg_dewhitelist_oa_regs(9) — like, the kernel API manual, bestie ✨

okay so picture this: it's the Kernel API Manual, and today's main character is xe_reg_dewhitelist_oa_regs. Yes that's a mouthful. No I will not be shortening it. She earned that name. 🎀

🌸 NAME 🌸

xe_reg_dewhitelist_oa_regs — dewhitelist oa registers for gt. that's it. that's the whole vibe. she takes the OA registers and she dewhitelists them, for a gt. periodt. 💅

---

🦋 SYNOPSIS 🦋

void xe_reg_dewhitelist_oa_regs (struct xe_gt *gt );

literally one function, one argument, returns nothing (void, she gives nothing back and that's iconic of her). 🫶

---

✨ ARGUMENTS ✨

• gt — the gt you want to dewhitelist oa registers for. that's the whole job. you hand her a gt, she handles the oa registers. no cap. 💖

---

🔥 DESCRIPTION 🔥

so what does she actually do? she dewhitelists the OA registers by setting RING_FORCE_TO_NONPRIV_DENY. that's the mechanic. that's the whole thing. she's not out here doing seventeen steps — she sets RING_FORCE_TO_NONPRIV_DENY and the OA registers are, officially, no longer whitelisted. slay. ⭐

ngl the naming is doing a lot of work here (dewhitelist is gonna live in your head rent free, sorry), but the behaviour is exactly what it says on the tin: whitelist revoked, RING_FORCE_TO_NONPRIV_DENY set, gt handled. 👑
