Re: [Xen-users] gplpv drivers

[Matthias <matthias.kannenberg@xxxxxxxxxxxxxx>]

On the one hand, yes, the most recent prebuild drivers are about a
year old. This is because James Harper is doing, as far as I
understood, a major rework on them tu cut irq usage to a minimum. But
this seems to be mostly done and a new beta version for first testing
will be released more sooner then later.

On the other hand, you really should have a decent performance even
without gplpv driver and near-native performance with the current one
year old ones. So if you got major performance issues, it's very
likely that this is not a gplpv issue. Two years ago I had a similar
issue and found out I had to disable C-States in dom0 to get decent
performance in my Windows domU. Just to show you that the issue can be
in an entirely different place.

Also, don't get your hopes too high on the new gplpv drivers cause
afaik James uses a Win7 for testing his drivers and I haven't heard
from anyone testing them on Win2012 yet. But never the less I added
him in cc, maybe he can clerify the situation a bit more.
