[Xen-devel] [PATCH V14 0/7] Mem_access for ARM

2015-03-26 Thread Tamas K Lengyel
The ARM virtualization extension provides 2-stage paging, a similar mechanisms to Intel's EPT, which can be used to trace the memory accesses performed by the guest systems. This series sets up the necessary infrastructure in the ARM code to deliver the event on R/W/X traps. Finally, we turn on the
