Re: [Xen-devel] Xen PV: Sample new PV driver for buffer sharing between domains

[Omkar Bolla <omkar.bolla@xxxxxxxxxxxxxxxxxxx>]

Hi,

I have started finding which patch introduced Armv8 Secondary CPUs issue.

I just want to start PV vdevb before domainU debian rootfs mount. Is it possible?

Thanks,

Omkar B

This is because you can't bring up secondary CPUs on the Hikey with Xen
4.11 [1], right? It would be nice to find where the bug was introduced
because Xen 4.8 is out of support and does not contain the latest fixes
(such as Meltdown/Spectre).

You would have to write your own PV drivers or port the series to Xen 4.8.

Cheers,
