Yeah, really it is !
After try upstream qemu and upstream kernel, for me, neither them can
work well. For xilinx qemu with xilinux kernel, it should be well,
although I still met issue below, is what I have done incorrect?
For kernel:
put rootfs.cpio in kernel root directory,
mv qemu_microblaze_defconfig to arch/microblaze/config/mmu_defconfig
make ARCH=microblaze CROSS_COMPILE=/usr/bin/microblaze-linux-gnu-
mmu_defconfig
make -j4
For qemu:
./configure --target-list="microblaze-softmmu" --enable-fdt --disable-kvm
make -j4
/upstream/xilinx/qemu/microblaze-softmmu/qemu-system-microblaze -M
