Doubt regarding virtual memory mapping from hypervisor to a domain
Hi,
I have allocated few order=9 pages in Xen memory space using
alloc_domheap_pages(NULL,9,0) during boot time just before domain is
created (dom0 = domain_create(0, DOMCRF_s3_integrity, DOM0_SSIDREF) in
xen/arch/x86/setup.c).
I got the following virtual addresses in xen log message-
(XEN) a2k2: Virt_addr:ffff83011cc00000 MFN:11cc00
(XEN) a2k2: Virt_addr:ffff83011ca00000 MFN:11ca00
(XEN)
