running qemu on x86 to emulate t2080 (e6500 cores)

running qemu on x86 to emulate t2080 (e6500 cores)

[Ruiz Ramos, Daniel Norberto]

Hello All,
My name is Daniel and this is my first post here.

Im trying to emulate a T2080RDB for testing images generated with bitbake, but I have not luck with it. I couldn't find any qemu that support -cpu e6500 option.
I've tried compiling qemu from source, and even all qemus that there are in my yocto project build.
All qemu says the same:

$ ./qemu-system-ppc64 -machine ppce500 -cpu e6500
Unable to initialize CPU!


¿Does anybody knows if the new cpu of Freescale is not supported?

Daniel.

Hello Daniel, 

Currently the x86 host QEMU emulation of QorIQ targets are not supported. QorIQ SDK can support the QorIQ boards QEMU emulation on target boards.

Zhenhua

QEMU emulation on target is more regarding providing runtime isolation
than emulation itself, isn't it?

[Ruiz Ramos, Daniel Norberto]

Thank you for your quick answer Zhenhua,
Please correct me if I'm wrong, but the qemu-system-ppc64 compiled to x86 can support  the previous e5500 core through -cpu e5500 option.
¿Does it mean that there are some partial QorIQ hardware  emulation on x86 host QEMU?
¿Or we are talking about all qemus in Freescale SDK is only focused to let powerpc hardware emulates it-self?

Best regards,
Daniel.

[Luo Zhenhua]

Hi Otavio, 

Please see the following description of the QEMU support in QorIQ SDK.

" On the target we do not need full emulation, we use QEMU + KVM. And the purpose of such a scenario would be to be able to run multiple machines on the same hardware with as little as possible overhead and of course this will include isolation, partitioning of the hardware resources, direct access to some hardware resources.

On x86 we would need full emulation of the platform, of course in this situation the overhead would be significant. A situation in which such a scenario could be used is software development/debugging on an emulated platform." 


Best Regards,

Zhenhua

Re: running qemu on x86 to emulate t2080 (e6500 cores)

[Luo Zhenhua]

Hi Daniel, 

The x86-host QEMU emulation for QorIQ targets is not verified in QorIQ SDK, so it is not officially supported in SDK. SDK focus on self-emulation on QorIQ targets. 

It is possible to emulate the QorIQ targets on x86 host if corresponding core types are supported in opensource QEMU code, like what you mentioned below, only partial QorIQ HWs can be emulated.

Zhenhua
