[Xen-devel] Status of "dma, x86, xen: reduce SWIOTLB usage in Xen guests" series


We are having problems related to mptsas and "swiotlb buffer is full" with the 
Xen4CentOS kernel (3.18). It looks like the last related work was
the series 
http://lists.xenproject.org/archives/html/xen-devel/2014-12/msg00770.html back 
at the end of 2014 and I'm wondering if there are any plans
to revive the series.

The error with swiotlb has caused us a massive amount of problems. We set 
swiotlb=32768 on one server and are still seeing this error message on
occasion. If there's anything I can do to help please let me know.
