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. > > now.

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.

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. > I'd rather keep as it is for armv8a defconfig, becasue it's the base, > any change may affect existing user. 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.

[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". > --- a/mk/rte.module.mk > +++ b/mk/rte.module.mk > + Linaro toolchain usages arm64 instread of aarch64 in kernel ifeq > +($(ARCH), aarch64) ARCH = arm64 endif Could you provide more explanations please? aarch64 shouldn't be used I think. [Hemant] you are right. This is not required. I was using an old toolchain.
