Subject: [PATCH v4 00/14] Argo: hypervisor-mediated interdomain communication
Date: Tue, 15 Jan 2019 01:27:32 -0800	[thread overview]
Message-ID: <1547544466-21135-1-git-send-email-christopher.w.clark@gmail.com> (raw)

Version four of this patch series.

* Changes are primarily addressing feedback from the v3 series reviews.
  Many points noted on the invididual commit posts.

* Register ring interfaces uses Xen gfns as page identifiers,
  and the arguments no longer specify page granularity.

* Multi-level lock validation macros defined and applied.
  Locks renamed to improve readability.

* Hypercall argument struct checking is folded inline into the series,
  checks applied as types are introduced.

* argo-mac string boot parameter changed to argo-mac-permissive boolean

Feedback items that are remaining to be addressed have been noted with
comments in the commit message and at the location in the code.
