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

["Huang2, Wei" <Wei.Huang2@xxxxxxx>]

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?

 

Thanks,

 

-Wei
