From e77673d14f2cec6d47d2da4e58dce87c2d66e54f Mon Sep 17 00:00:00 2001 From: Mukul Joshi Date: Fri, 9 Jun 2023 11:11:53 -0400 Subject: drm/amdgpu: Update invalid PTE flag setting MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Update the invalid PTE flag setting with TF enabled. This is to ensure, in addition to transitioning the retry fault to a no-retry fault, it also causes the wavefront to enter the trap handler. With the current setting, the fault only transitions to a no-retry fault. Additionally, have 2 sets of invalid PTE settings, one for TF enabled, the other for TF disabled. The setting with TF disabled, doesn't work with TF enabled.
