CUDA fixed VA allocations and sparse mappings
...t; PAGE_OFFSET macro which is the start of kernel virtual address space.
You need to be carefull here, first the hardware might not have as many bit
as the CPU. For instance x86-64 have a 48bits for virtual address ie only
48bits of the address is meaning full, older radeon (<CI iirc) only have
40bits for the address bus. With such configuration you could not move all
private kernel allocation inside the kernel zone.
Second issue is thing like 32bit process on 64bit kernel, in which case
you have the usual 3GB userspace, 1GB kernel space split. So instead of
using PAGE_OFFSET you might want to...

[PATCH 0 of 3] RFC Paging support for AMD NPT V2
There has been some progress, but still no joy. Definitely not intended for
inclusion at this point.
Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table
sharing.
Tim, I verified that changes to p2m-pt.c don''t break shadow mode (64bit
hypervisor and Win 7 guest).
Hongkaixing, I incorporated your suggestion in patch 2, so I should add your
Signed-off-by eventually.

GeForce(R) GT 710 1GB PCIE x 1 on arm64
Hi to all.
I'm experimenting with running a
https://www.zotac.com/us/product/graphics_card/geforce%C2%AE-gt-710-1gb-pcie-x-1
card on an Nvidia Jetson TX2 arm64 device.
Possible?
Linux kernel aarch64 5.6.10.
Because Nvidia did not list drivers for this architecture, I'm
experimenting with a nouveau driver.
The Jetson TX2 has a default driver for the host1x framebuffer for output
from the
