Re: [XenARM] About Tegra2 Xen-ARM porting

[Dongsoo Kim <dongsoo.kim@xxxxxxxxxxxxxxxx>]

Hi,

First of all, thank you for kind comment.

I see that PV needs modified kernel and asking a proper PV kernel
repository for Tegra250.

As far as I follow, at Xen Asia VP Suh has announced their works with
Tegra2 (kernel 2.6.29 maybe).

If company and engineers don't mind, I wanna ask to let me find the
proper kernel code.

It will be extremely helpful to follow up the latest version. And I
may be able to contribute something then.

Cheers,
