From 0698ff57bf327d9a5735a898f78161b8dada160b Mon Sep 17 00:00:00 2001 From: Michal Wajdeczko Date: Mon, 27 May 2024 13:54:08 +0200 Subject: [PATCH] drm/xe/pf: Update the LMTT when freeing VF GT config MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The LMTT must be updated whenever we change the VF LMEM configuration. We missed that step when freeing the whole VF GT config, which could result in stale PTE in LMTT or LMTT PT object leaks. Fix that.
