Subject: Panic when PCI trying to read secure mem area.

Hi,

I am getting a kernel panic when PCI is trying to read at 0xe0880000 in VIRT_SECURE_MEM area. ([VIRT_SECURE_MEM] = { 0x0e000000, 0x01000000 })

It happens on 3.1.0 as well. I tried with secure=on/off. Same command works on qemu-2.5.0.

Linux kernel is configured with “make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- multi_v7_defconfig”

Please help.

$> qemu-3.0.0/build/arm-softmmu/qemu-system-arm -m 512 -M virt,secure=on -kernel ~/linux-4.4.15/arch/arm/boot/zImage -append "rdinit=/sbin/init" -initrd ~/initrd.img.gz -nographic
