Re: [Xen-devel] Emulation of xen ARM on qemux86_64

[Iurii Mykhalskyi <iurii.mykhalskyi@xxxxxxxxxxxxxxx>]

Hi Pranay,

As I say in my previous e-mail: 

"I'm not familiar with QEMU, but  in general case - you can't just take image (for example RCAR-H3) and run it inside QEMU - a some things might be different - uart, gic, timer, etc.

And i'm not sure about support of HW virtualization on QEMU - looks like your are asking about emulation ARM HW virtualization on X86_64 platform."

I don't think that it is possible to emulate ARM HW virtualization on x86_64 platform via QEMU.

So - in my opinion -  layers such as you are asking doesn't existing for QEMU.

According to [1] looks like ARM Ltd provides emulator, called ARMv8 Foundation Model  - that is supports Xen [2].

But I never used it and looks like its not free and has some limited trial period.

Hi,

    Thank you for the quick response.

What I wanted to know is that if there is any yocto layer support for XEN-ARM on QEMU machine, which could be used for testing purposes. Like for RCAR there is a [1] Meta-platform-xen layer which provides support for RCAR. Same way, is there a layer which can be used for QEMU?

If you want to play with virtualization, try to get some widely available board - Allwinner based or some OMAP4/5 based boards, etc [1]

For debug purposes we are mostly using printk  and sometimes blinking LEDS :)

Hi,

I am new to xen-arm development on yocto-project. Right now i don't have the hardware, but i was able to create an image of xen-arm for RCAR-H3. I wanted to see how xen-arm works, so was wondering if xen-arm can be implemented to be used with a qemu machine. If so please let me know where can i find the resources. Also which debugger would you recommend to be used with the RCAR-H3.

It would be really kind of you if you could solve my queries.

Thanks,
