Subject: [RFC PATCH V3 00/12] xen: Clean-up of mem_event subsystem
Date: Thu, 29 Jan 2015 22:46:26 +0100 [thread overview]
Message-ID: <1422567998-29995-1-git-send-email-tamas.lengyel@zentific.com> (raw)
This patch series aims to clean up the mem_event subsystem within Xen. The
original use-case for this system was to allow external helper applications
running in privileged domains to control various memory operations performed
by Xen. Amongs these were paging, sharing and access control. The subsystem
has since been extended to also deliver non-memory related events, namely
various HVM debugging events (INT3, MTF, MOV-TO-CR, MOV-TO-MSR). The structures
and naming of related functions however has not caught up to these new
use-cases, thus leaving many ambiguities in the code. Furthermore, future
use-cases envisioned for this subsystem include PV domains and ARM domains,
thus there is a need to establish a common base to build on.
In this series we convert the mem_event system to vm_event in which we clearly
define the scope of information that is transmitted via the event
delivery mechanism. Afterwards, we clean up the naming of the structures and
related functions to more clearly be in line with their actual operations.
Finally, the control of monitor events is moved to a new domctl, monitor_op.
This RFC PATCH series is also available at:
