Re: [Xen-devel] X86 Community Call: Wed March 14, 15:00 - 16:00 UTC



Hi all,

this is my first go at the agenda. 
See 
https://docs.google.com/document/d/1n7HAu5IbuRt5aJbQKt5X470kv2Ubvk5P2mG0vp6rKfU/edit?usp=sharing
 and attached PDF

Text without tables below

As I didn't get a priority order, nor design stuff, but a few series to discuss 
I sorted by what looked sensible to me
If you feel strongly about the order, please let me know ASAP

A) What looks feasible for 4.11 => 2 series
B) Longer term: non-RFC series with more than one revision => 2 series
C) Longer term: RFC series - v > 1 first, then sorted by size => 8 series
D) AOB
We should allocate 5 minutes at the end to
* Reflect on meeting format/improvements
* Should we use a different mechanism for the call (e.g. a video facility)

Regards
Lars

== For 4.11

=== [PATCH v4 00/10] x86: emulator enhancements
Sent in for meeting agenda by George
https://marc.info/?l=xen-devel&m=151982229407799 
https://xen.markmail.org/thread/roukz6r3gcuhxinn 

Notes: v4 posted by Jan Beulich on 28 Feb 2018.  Most patches seem to have acks 
or r-bs, but I know this one has been around a long time, so it might be worth 
making sure we can get it in before the feature freeze. 

[Table in PDF] - shows that apart from 1 design approach disagreement and 16/20 
not having had review this series looks pretty close

=== [PATCH v17 00/11] x86: guest resource mapping
Sent in for meeting agenda by George
https://xen.markmail.org/thread/ge2hlgljac3uqepe 

v17 posted by Paul Durrant on 3 January 2018

Notes: All but 6/11 have a fair amount of A-b's or R-b’s
Is this a patch we can get into 4.11?

[Table in PDF] - Looks pretty close also

== Longer Term - non-RFCs

which has underlying issues, which may be a problem.
