[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] Re: [Minios-devel] [UNIKRAFT/NEWLIB PATCH 1/1] Add patch to have newlib running on ARM64
Hi Julien,
The problem is the same one encountered by Justin, quoted "some fdt nodes are
parsed incorrectly, especially for those compatible strings with "\0"". This
seems to be a newlib bug when compiling for ARM64.
Instead of using Justin's workaround that adds the -DPREFER_SIZE_OVER_SPEED
flag, this patch attempts to solve it in a more robust way by using the machine
specific source files, written and tested for ARM64.
Without the patch, the output we see is:
qemu-system-aarch64 -machine virt -cpu cortex-a53 -display none -serial stdio
-m 32M -kernel ./build/helloworld_kvm-arm64

This commit does not explain what sort of problem is encountered and why
using machine specific will solve it.
Technically generic code should work for all the architectures but may
not be efficient. So what is the exact problem here?
