From 3a4132e6cb4879764d886f11b9fd225197fb48dd Mon Sep 17 00:00:00 2001 From: =?utf8?q?Timur=20Krist=C3=B3f?= Date: Fri, 7 Nov 2025 16:57:34 +0100 Subject: [PATCH] drm/amdgpu/gmc6: Place gart at low address range MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Instead of using a best-fit algorithm to determine which part of the VMID 0 address space to use for GART, always use the low address range. A subsequent commit will use this to map the VCPU BO in GART for the VCE1 IP block. Split this into a separate patch to make it easier to bisect, in case there are any errors in the future.
