<id>urn:sha1:34e5a54327dce5033582f3609eb54812a8c61b90</id>
<content type='text'>
This reverts commit c105518679b6e87232874ffc989ec403bee59664.

This patch disables the TOPDOWN flag for APU and few dGPU cards
which has the VRAM size equal to the BAR size.

When we enable the TOPDOWN flag, we get the free blocks at
the highest available memory region and we don't split the
lower order blocks. This change is required to keep off
the fragmentation related issues particularly in ASIC
which has VRAM space &lt;= 500MiB

Hence, we are reverting this patch.

<title>drm/amdgpu: fix Null pointer dereference error in amdgpu_device_recover_vram</title>

<content type='text'>
Use the function of amdgpu_bo_vm_destroy to handle the resource release
of shadow bo. During the amdgpu_mes_self_test, shadow bo released, but
vmbo-&gt;shadow_list was not, which caused a null pointer reference error
in amdgpu_device_recover_vram when GPU reset.

Fixes: 6c032c37ac3e ("drm/amdgpu: Fix vram recover doesn't work after whole GPU reset (v2)")

<title>drm/amdgpu: remove TOPDOWN flags when allocating VRAM in large bar system</title>

<id>urn:sha1:c105518679b6e87232874ffc989ec403bee59664</id>
<content type='text'>
Since VRAM manager is changed from drm mm to drm buddy, the
TOP_DOWN flag should not be set by default in the large bar system.
Removing this flag helps improve drm buddy allocator efficiency and
reduce the risk of splitting higher order block into lower order.
