[Qemu-devel] qemu-arm does not boot kernel since 3.19

[Waldemar Brodkorb]

Hi,

I am regulary using qemu with arm.
Since Linux 3.19 my system no longer boots.
I am using Qemu 2.2.0 on Linux/amd64.

System is started via:
qemu-system-arm -nographic -M vexpress-a9 -cpu cortex-a9 -net user
-net nic,model=lan9118 -kernel qemu-arm-initramfspiggyback-kernel

I have read, they changed a lot for ARM SoCs in 3.19 and for
Vexpress support. Do I need to provide a DTB to get it running?

The screen just stays black, I have no idea what's wrong here.

Any hints are welcome.

best regards
 Waldemar

Yes, I expect that you need a dtb. Otherwise the easiest
way to find out what's wrong is probably to bisect the
kernel.
