From a44592339397bc6715917997c6869bdedd1a7256 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Timur=20Krist=C3=B3f?= Date: Wed, 19 Nov 2025 10:25:42 +0100 Subject: [PATCH 5392/5403] drm/amdgpu/vm: Check PRT uAPI flag instead of PTE flag MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This fixes sparse mappings (aka. partially resident textures). Check the correct flags. Since a recent refactor, the code works with uAPI flags (for mapping buffer objects), and not PTE (page table entry) flags.
