GPLPV drivers update

GPLPV drivers update

[James Harper]

I have just uploaded a new testing version of GPL PV drivers for
Windows. Have a look for 0.10.0.97-dontuse at
http://www.meadowcourt.org/downloads (the -dontuse bit is to scare
people away who haven't read this email :)

As usual, please test thoroughly on a test DomU and make sure you have a
backup before installing on a non-test system. In particular, I'm only
testing with Xen 3.4.1 these days so anything older isn't tested
although it should work.

There was a problem with the signing of the drivers that would prevent
them working properly under Vista/2008 x64 even with testsigning
enabled. This should resolve that.

The installation procedure for Vista/2008 x64 is as follows:
. Run 'bcdedit /set testsigning on'
. Reboot
. Install the drivers. Accept any warnings and tick 'always trust...'
when prompted.
. Make sure you now have PV network and SCSI adapters present
. Reboot

If something doesn't work, you should be able to boot to safe mode
unless you forgot to run 'bcdedit /set testsigning on' in which case you
will probably have an unbootable system... for some reason the vista F8
boot menu doesn't allow you to turn on testsigning and safe mode at the
same time. Ideally the installer would be able to detect that we are
using a test certificate and instruct you to turn on testsigning first
but I don't yet know how to do that. I'll see if I can at least put in a
loud warning at installation time...

James,

Happy to report that I've tested the new drivers on a freshly
installed windows 2008 x64 hvm and after following your instructions
and rebooting the correct drivers appeared in device manager and the
performance increased as expected.

Then I decided to try backing out the kludge I had added to
makedist.bat to bypass signing, this time a new certificate was
generated and the drivers compiled without error, but during
installation the system bugchecked with a error in xenpci.sys, after
rebooting I retried the installation and the correct Xen PCI device
driver and other devices were detected but when I rebooted again the
system bugchecked.

I will do more testing to see if I get consistent results, I would
expect the msi that you released and the one I compiled to behave
exactly the same as I did a "hg pull" before compiling and "hg diff"
shows that my tree is the same as yours.

Just tried installing your MSI onto the 2008x64 hvm and got the same
bugcheck, so it seems to be slightly random...

What bugcheck? If you are running 3.4.x it should now print the bugcheck
info into /var/log/qemu-dm-<domain name>.log

That's a nice feature!, here it is:

XenPCI --> XenPci_SysrqHandXenPCI     Bug check 0x000000D1
(0x0000000000000000, 0x0000000000000002, 0x0000000000000001,

Hmmm... null pointer dereference by the looks of it.

Using the newest drivers, the installer fails with 'the installer ended
prematurely'
