Thread-topic: [Xen-devel] map_domain_page
it is to map a machine page into Xen address space. Xen only has 64M virtual address space on x86_32 , or 168M on PAE Xen, so it uses a cache mechanism to maintain the mapping between xen va and machine page.

Hi,

 

Can anybody shed light on the Xen function map_domain_page (in xen/arch/x86/x86_32/domain_page.c)? What is it doing?
