[Xen-devel] Release 0.8.5 of GPL PV drivers for Windows



I've just uploaded 0.8.5. Please uninstall all the 0.8.4 drivers first
or you'll get BSoD's on attempting the upgrade. I'm sure there's a way
to make this a bit cleaner (eg require a reboot instead of crashing) but
I don't know how at this point.

Download from http://www.meadowcourt.org/WindowsXenPV-0.8.5.zip

Major changes are:
. TCP large send offload and other performance enhancements
. The system should crash with a BSoD if it fails to 'hide' the Qemu
Intel IDE device, which is much better than silent corruption.
. Fixes to the above hiding to properly detect the PCI Bus device driver
under non-English languages
. Beginnings of suspend (required for migration). The Suspend part
appears to work, but the resume doesn't.

I have a feeling that the large send offload stuff is breaking local (eg
inside Dom0's bridge) communications, as the packets stay 'large' until
they leave via a physical adapter. Windows doesn't like receiving
packets larger than the MTU (and Wireshark causes a BSoD). Unless I can
find an alternative I'll have to have the Windows xennet driver break
them up itself, which might erode any performance benefit.

I'd be grateful if anyone who has posted previous iperf results could
re-test under this version.

Thanks

James
