Re: [Xen-devel] [PATCH 0/2][PV-on-HVM] Enable Front-end drivers for 2.4 kernels



I was thinking about solutions other than using ifdefs all over the place. Given that the canonical drivers will soon be the upstream kernel.org versions, we need a solution that doesn’t rely on ifdefs in .c files (since that seems to get rejected upstream). The ‘driver kit’ I was thinking of sounds rather like your own 2.4.*-xen.hg suggestion. Maybe that would be best.

Which parts in particular concern you? If you could propose some suggestions - we could try another rev.

How would this patch lead to code divergence as submitted?

An ideal solution would be a 2.4.*-xen.hg tree which would support both PV, and PV-on-HVM solutions. However, that was not the goal of these patches.
