Hi,
Anyone knows if VPP can support ARM64 64K pagesize?
Or anyone has experiences on below issue?
Thank you!
Here is the kernel config.
# CONFIG_ARM64_4K_PAGES is not set
# CONFIG_ARM64_16K_PAGES is not set
CONFIG_ARM64_64K_PAGES=y
VPP reports a lot of errors when it starts up on ARM64 64k pagesize
enviroment.

The source code of the error is at mprotect(). It seems that VPP
memeory management may not support 64K pagesize.

if (mprotect (p->stack, page_size, PROT_READ) < 0)
