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) a2k2: Virt_addr:ffff83011c800000 MFN:11c800
(XEN) a2k2: Virt_addr:ffff83011c600000 MFN:11c600
(XEN) a2k2: Virt_addr:ffff83011c400000 MFN:11c400
(XEN) a2k2: Virt_addr:ffff83011c200000 MFN:11c20...

PATCH: Hugepage support for Domains booting with 4KB pages
We have implemented hugepage support for guests in following manner
In
our implementation we added a parameter hugepage_num which is specified
in the config file of the DomU. It is the number of hugepages that the
guest is guaranteed to receive whenever the kernel asks for hugepage by
using its boot time parameter or reserving after booting (eg. Using echo
XX > /proc/sys/vm/nr_hugepages).
