From fdea94a4c25a9923f7418325f45951431945d14c Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Wed, 17 Apr 2024 16:39:48 -0400 Subject: [PATCH] drm/xe: Convert xe_gem_fault to use direct xe_pm_runtime calls The gem page fault is one of the outer bound protections where we want to ensure that the hardware is in D0 before proceeding with memory access. Let's convert it towards the xe_pm_runtime functions directly so we can then convert the mem_access to be inner protection only and then Kill it for good.
