Re: ARM - Successful install on RockPro64

[Richard Simpson <xen@xxxxxxxxxxxxxxx>]

Dear Bertrand,

Just to confirm that the Linux distro is Gentoo.  I know it's not very 
common these days, but I have used it for very many years and it is what 
I am used to.
Gentoo has a xen package but only for arm32 and then masked as unstable 
so I just grabbed 4.13 via git.  It also has a xen-tools package which 
is packaged for arm64 (although still masked as unstable) so I unmasked 
and used that.  There were a couple of dependency problems with the 
package but after I resolved those it seemed to work OK.
There is also a Gentoo u-boot tools package for arm64 but again I got 
u-boot via git.
I would be happy to try to report my success via the smoke test page 
(https://wiki.xenproject.org/wiki/Xen_ARM_Manual_Smoke_Test/Results) if 
I can figure out how.  Strangely, I can't see anything listed under 
"Test Results" from anyone else.  Perhaps it is a problem with my browser.
I also notice an instruction which reads "Test hypervisor 
functionalities: clone raisin on the platform and run ./raise test".  I 
can try to do this if it will help.  Do I just run "git clone <link from 
web page>" and then presumably the test prints out some results?
Happy to try a beta version of Xen if you decide to include the patch 
and I can also try some of the interrupt config options if you want.
Cheers,

    Richard
