Could you provide more explanations please?
aarch64 shouldn't be used I think.

There is nothing specific in this file.
[Hemant] The arch is "armv8-a" instead of "armv8-a+crc". Also, we are using "mcpu" for ARM tuning. This is not present in the armv8a machine. The armv7a machine usages RTE_ARCH_ARM_TUNE to configure "mtune".

aarch64 shouldn't be used I think.
[Hemant] you are right. This is not required. I was using an old toolchain.

I think it makes sense to move this option to generic arm64 config
as upstream arm64 kernel does not have support for sysfs based PCI mmap
resource file,(/sys/bus/pci/devices/B:D:F/resource[_wc]X) need for
CONFIG_RTE_EAL_IGB_UIO to work) and use VFIO for all cases.
Any objections?

I think it makes sense to move this option to generic arm64 config
as upstream arm64 kernel does not have support for sysfs based PCI mmap
resource file,(/sys/bus/pci/devices/B:D:F/resource[_wc]X) need for
CONFIG_RTE_EAL_IGB_UIO to work) and use VFIO for all cases.
Any objections?
Make sense. IGB_UIO for arm64 is NA.
+1
I can take care of it in next version of patch

So no conflict to enable both.
I'd rather keep as it is for armv8a defconfig, becasue it's the base,
any change may affect existing user.

IMO, Conflict part comes secondary, It does not even work with upstream kernel.
Why keep the broken configuration? Two main reasons I think it makes
sense to disable
- It is broken, I don't think arm64 kernel developers likes non VFIO approach
now. So mostly likely it will be broken
- Trying to avoid out of tree patches wherever is possible as
distribution folks like to work with upstream version.

IMO, It makes sense to disable at armv8a defconfig otherwise all armv8
variants need add CONFIG_RTE_EAL_IGB_UIO=n in all the configs and its
arch specific issue.

I don't think DPDK user is kernel developer in most cases. They maybe
like the traditional way.

Agree. But there is possible that people/company maintain their own kernel tree.

We don't have to do that.
You didn't explictly disable this config in your current
defconfig_arm64-thunderx-linuxapp-gcc, but you know which module to
bind.

But, the traditional way is _broken_. If we create the shortcut in
dpdk.org then upstream arm64 linux kernel will never get fixed.I attempted
twice to fix it, but arm64 kernel developers like VFIO approach.
if you think it makes sense to have traditional way then can you
upstream the patch to the arm64 linux kernel and add it in common
config
Technically, with VFIO and VFIONOIOMMU way we can replace the need for
uio in both host and virtualization use cases for arm64.

This excactly same thing we would like to avoid in long term.

But not all the end users.
