Subject: [PATCH 02/14] drm/amdgpu/gmc6: Place gart at low address range
Date: Tue, 28 Oct 2025 23:06:16 +0100	[thread overview]
Message-ID: <20251028220628.8371-3-timur.kristof@gmail.com> (raw)
In-Reply-To: <20251028220628.8371-1-timur.kristof@gmail.com>

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.
