Would the following be equivalent to what you intended with your commit?
Looks a bit awkward but hibernate/resume work with it for 6.0.19 (and a Ryzen
5600G):


uint32_t amdgpu_bo_get_preferred_domain(struct amdgpu_device *adev,
                                            uint32_t domain)
{
        if (domain == (AMDGPU_GEM_DOMAIN_VRAM | AMDGPU_GEM_DOMAIN_GTT)) {
                domain = AMDGPU_GEM_DOMAIN_VRAM;
                if ((adev->asic_type == CHIP_CARRIZO) || (adev->asic_type ==
CHIP_STONEY)) {
                        if (adev->gmc.real_vram_size <= AMDGPU_SG_THRESHOLD)
                                domain = AMDGPU_GEM_DOMAIN_GTT;
                }
        }
        return domain;
}


Let me know whether this is worth persuing. I could then test it with 5.15.88
and 6.1.6.
