Dear all,
I have a Linux kernel v5.10.27 build for arm64 architecture that is runnable on Gem5. Now I want to
run it on Qemu-system-aarch64, but I haven't figure out the proper command and parameters yet. Here
is the few things I have tried:
- qemu-system-aarch64 -M vexpress-a15 --cpu cortex-a15 -m 2048 --kernel
output/vmlinux
From the Gem5 source code, I know Gem5 implements Arm CoreTile Express A15x2 (V2P-CA15) (from the
comment in src/dev/arm/RealView.py). It has Cortex-A15. So I chose the parameters like above.
However, it showed the following error:
qemu-system-aarch64: Trying to execute code outside RAM or ROM at
0x0000000004000000
The reason I think is vexpress-a15 and cortex-a15 are arm architecture, not arm64. I tried a few
other parameters like cortex-a53, cortex-a57, versatileab, versatilepb, but all of them do not work.
So how can I run the kernel on Qemu?
And besides, I wonder how Gem5 implements Arm CoreTile Express A15x2 (ARM arch) and supports ARMv8
(arm64 arch) at the same time?
Maybe post to the qemu mailing lists? EM
