hi all: I try to use qemu-system-aarch64 windows binary for running arm64 defconfig kernel image but get Synchronous External Abort while booting PCI devices. The same Image that run on qemu-system-aarch64 linux binary is fine. Is there any pci related kernel config need to be removed while using qemu windows binary?
Appreciate ur help in advance.
=============================
My environment are:
1. the versionof qemu-system-aarch64 windows binary is 4.0.92
2. kernel image:
a. check out latest kernel from
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
b. make ARCH=arm64 defconfig
c. make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j32
3. run qemu with attach "qemu_run.sh"
Boot up fail log is attached
"qemu_win10_binary_bootup_aarch64_defconfig_fail.log.tar.bz2"
============================
below is excerpt from log, where Synchronous External Abort happens.
