RE: [Xen-devel] Re: [RFC][PATCH]Large Page Support for HAP

To get round the 2M/4M distinction I’d write code in terms of ‘normal page’ and ‘super page’, where the former is order 0 and the latter is order L2_SUPERPAGE_ORDER (or somesuch name). I would try to avoid referencing 2M or 4M explicitly as much as possible.


Will do it.


Having to shatter the 0-2MB region for the VGA RAM hole is a shame, but I suppose there’s no way round that really.


Since tools control the page_array (size, order, etc.), this is the only way to do it. My major concern is about handing 4MB page for 32bit mode and impacts to shadow paging. Any thought?
