This change reverses the task of xenpaging. Before this change a fixed number of pages was paged out. With this change the guest will not have access to more than the given number of pages at the same time. The xenpaging= config option is replaced by actmem= A new xm mem-swap-target is added. The xenpaging binary is moved to /usr/lib/xen/bin/ xenpaging.HVMCOPY_gfn_paged_out.patch xenpaging.XEN_PAGING_DIR.patch xenpaging.add_evict_pages.patch xenpaging.bitmap_clear.patch xenpaging.cmdline-interface.patch xenpaging.encapsulate_domain_info.patch xenpaging.file_op-return-code.patch xenpaging.guest-memusage.patch xenpaging.install-to-libexec.patch xenpaging.low_target_policy_nomru.patch xenpaging.main-loop-exit-handling.patch xenpaging.misleading-comment.patch xenpaging.page_in-munmap-size.patch xenpaging.print-gfn.patch xenpaging.record-numer-paged-out-pages.patch xenpaging.reset-uncomsumed.patch xenpaging.stale-comments.patch xenpaging.target-tot_pages.patch xenpaging.use-PERROR.patch xenpaging.watch-target-tot_pages.patch xenpaging.watch_event-DPRINTF.patch xenpaging.xc_interface_open-comment.patch - xen.spec: update filelist package /usr/lib*/xen with wildcard to pickup new files remove duplicate /usr/sbin/xen-list from filelist OBS-URL: https://build.opensuse.org/package/show/Virtualization/xen?expand=0&rev=157

xenpaging: munmap all pages after page-in
|
|
|
|
Do munmap() on all mapped pages, not just the first one. Without this
|
|
change the gfns backing the remaining pages can not be paged out again
|
|
because the page count does not go down to 1. This change was missing
|
|
from changeset 23827:d1d6abc1db20.
