Hi all, this patch series introduces stolen ticks accounting for Xen on ARM. Stolen ticks are clocksource ticks that have been "stolen" from the cpu, typically because Linux is running in a virtual machine and the vcpu has been descheduled. To account for these ticks we introduce CONFIG_PARAVIRT and pv_time_ops so that we can make use of:

This series implements ballooning for Xen on ARM and builds and Mukesh''s PVH privcmd stuff to implement foreign page mapping on ARM, replacing the old "HACK: initial (very hacky) XENMAPSPACE_gmfn_foreign" patch. The baseline is a bit complex, it is basically Stefano''s xenarm-forlinus branch (commit bbd6eb29214e) merged with Konrad''s linux-next-pvh branch

Hi All, I followed the instructions here at http://bderzhavets.wordpress.com/2009/06/10/setup-fedora-11-pv-domu-at-xen-3-4-1-dom0-kernel-2-6-30-rc6-tip-on-top-of-fedora-11/ However, when I do a "make menuconfig", I cannot see any XEN related configuration options. What am I missing? Thank you. Mr. Teo En Ming Dip(Mechatronics Engineering) BEng(Hons)(Mechanical Engineering)
