We want to check the softmmu tlb availability, not
if we are targetting system emulation. Besides, this
code could be used by user emulation in the future.

The GPU memory is exposed as device BAR1 to the VM and is discovered
by QEMU through the VFIO_DEVICE_GET_REGION_INFO ioctl. QEMU performs

NVIDIA is building systems which allows the CPU to coherently access
GPU memory. This GPU device memory can be added and managed by the
kernel memory manager. The patch holds the required changes in QEMU
to expose this memory to the device assigned VMs.

From: Ankit Agrawal
The GPU device memory is reported to the VM as a BAR. The device memory
may not be aligned to the power-of-2, but the QEMU expects the PCI BAR to
be. Align the reported device memory size to the next power-of-2 before
QEMU does an mmap.

The guest VM adds the GPU memory as (upto 8) separate memory-less NUMA
nodes. ACPI SRAT need to thus insert proximity domains and tag them as
MEM_AFFINITY_HOTPLUGGABLE. The VM kernel can then parse the SRAT and
create NUMA nodes.

To add the memory in the guest as NUMA nodes, it needs the PXM node index
and the total count of nodes associated with the memory. The range of
proximity domains are communicated to the VM as part of the guest ACPI
using the nvidia,gpu-mem-pxm-start and nvidia,gpu-mem-pxm-coun
