Subject: [PATCH v3 00/15] Mem_event and mem_access for ARM
Date: Mon, 1 Sep 2014 16:21:54 +0200 [thread overview]
Message-ID: <1409581329-2607-1-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 has been fully tested and is functional on an
Arndale board.
This PATCH series is also available at:
https://github.com/tklengyel/xen/tree/arm_memaccess3
Tamas K Lengyel (15):
xen: Relocate mem_access and mem_event into common.
xen: Relocate struct npfec definition into common
xen: Relocate mem_event_op domctl and access_op memop into common.
xen/mem_event: Clean out superfluous white-spaces
xen/mem_event: Relax error condition on debug builds
xen/mem_event: Abstract architecture specific sanity checks
xen/mem_access: Abstract architecture specific sanity check
xen/arm: p2m type definitions and changes
xen/arm: Add set access required domctl
xen/arm: Data abort exception (R/W) mem_events.
xen/arm: Instruction prefetch abort (X) mem_event handling
xen/arm: Shatter large pages when using mem_acces
xen/arm: Enable the compilation of mem_access and mem_event on ARM.
tools/libxc: Allocate magic page for mem access on ARM
tools/tests: Enable xen-access on ARM
