Hi
This is the 4th version of multifd. Changes:
- XBZRLE don't need to be checked for
- Documentation and defaults are consistent
- split socketArgs
- use iovec instead of creating something similar.
- We use now the exported size of target page (another HACK removal)
- created qio_chanel_{wirtev,readv}_all functions. the _full() name
was already taken.
What they do is the same that the without _all() function, but if it
returns due to blocking it redo the call.
- it is checkpatch.pl clean now.
Please comment, Juan.
[v3]
- comments for previous verion addressed
- lots of bugs fixed
- remove DPRINTF from ram.c
- add multifd-group parameter, it gives how many pages we sent each
time to the worker threads. I am open to better names.
- Better flush support.
- with migration_set_speed 2G it is able to migrate "stress -vm 2
-vm-bytes 512M" over loopback.
Please review.
Thanks, Juan.
[v2]
This is a version against current code. It is based on top of QIO
work. It improves the thread synchronization and fixes the problem
when we could have two threads handing the same page.
Please comment, Juan.
