Subject: [PATCH for-4.5 v8 00/19] Mem_event and mem_access for ARM
Date: Tue, 23 Sep 2014 15:14:11 +0200 [thread overview]
Message-ID: <1411478070-13836-1-git-send-email-tklengyel@sec.in.tum.de> (raw)
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 moves the mem_access and mem_event codebase
into Xen common, performs some code cleanup and architecture specific division
of components, then sets up the necessary infrastructure in the ARM code
to deliver the event on R/W/X traps. Finally, we turn on the compilation of
mem_access and mem_event on ARM and perform the necessary changes to the tools side.
This version of the series is based on staging and has been fully tested on both
an Arndale board and on Intel hardware.
This PATCH series is also available at:
