[Xen-devel] Hypercall-page initialization

[Jacob Gorm Hansen <jacobg@xxxxxxx>]

hi,

I my unprivileged domain builder, I have run into the problem of how
to setup the hypercall-page. I suppose I can decode the kernel binary
header to figure out where to put the page, and then memcpy it from
loader to linux and things will work.

But wouldn't it be better if the hypercall used to populate the page
was available to the domU, so that its startup-code could call on Xen
to populate the page? I find the current approach of hardcoding the
page location in the kernel header pretty ugly.

Jacob
