Subject: [PATCH RFC 0/8] Xen: FIFO-based event channel ABI
Date: Tue, 19 Mar 2013 21:00:10 +0000 [thread overview]
Message-ID: <1363726818-25409-1-git-send-email-david.vrabel@citrix.com> (raw)
This is an RFC of the FIFO-based event channel ABI described in this
design document:
http://xenbits.xen.org/people/dvrabel/event-channels-C.pdf
Changes since draft B are:
- Queue tail is now private to Xen.
- Guest pages are specified by MFN in the hypercalls.
- Updated link/unlink algorithm to avoid races when adding an event to
a queue that is becoming empty.
Patch 1-5 do some preparatory work for supporting alternate ABIs.
Patch 6 is a hack to allow it to build.
Patch 7-8 add the ABI and the implementation. Patch 8 list some of
the known limitations with this RFC implementation.
David
