Release 0.9.8 of GPL PV Drivers for Windows

Release 0.9.8 of GPL PV Drivers for Windows

[James Harper]

I've just uploaded 0.9.8 to http://www.meadowcourt.org/downloads

As a reminder, the wiki page is
http://wiki.xensource.com/xenwiki/XenWindowsGplPv

This release fixes a bug which could be hit under high disk load (high
number of outstanding requests with fragmented sg lists) and would
reduce performance dramatically - my iometer testing went from 23MB/s to
0.5MB/s!

Also, xenvbd will now dump some stats to the kernel debug logs (use
debugview from sysinternals to view these) every 60 seconds. I'm not
sure how useful these might be yet.

Well after upgrading 0.9.6 (actually, first uninstalled those with the 
pre-0.9.0 instructies because of bsod when doing normal upgrade) I get 
instant lockups when doing anything I/O intensive! The domU will use 
100% CPU and just hangs forever as it seems (destroyed it after 5 min). 
The previous 0.9.6 seemed to be pretty stable, no lockups or whatsoever 
(and I'd already liked it's HD performance!) So not sure what's going 
wrong here, but in the meantime I get back to 0.9.6 (or I'll might also 
test 0.9.7 to clear things up).

So it doesn't come good by itself?

Are you using SMP? I thought I was but just noticed that my test machine
is UP at the moment.

Also, what sort of I/O intensive things are you doing? Is it something I
could reproduce easily?

Not sure, I destroyed it myself after 5 min, but it was completely 
unresponsive, so I guess would stay that way.

No, just testing with UP. I know SMP currently has a major performance 
hit somehow, so running it is out of the question.

Sure, I just started the HDTune test and it locked up immediately. Same for a JKDefrag defragmentation: http://www.kessels.com/JkDefrag/JkDefrag-3.34.zip (very good defragger btw!). Just launch the JKDefrag.exe inside without any parameters and it's starts defragging all local disks. This one locks up within a sec after launching (in it's analyse phase).

James tell us howto extract this and eventually howto repack this so 
that we could sign it.

If you don't tick 'Install Drivers' then the drivers should just be copied
into the "C:\Program Files\Xen PV Drivers\drivers" directory.

What's the easiest way to create the certificates necessary for signing?

Thanks

Ask CA-Cert to get currently best certs for this.

But how could i install then the signed drivers?

Getting a BSOD as soon as I start hdtune with these drivers on Win2k3 x64.

"Error code 000000000000001e, parameter1 ffffffff80000003, parameter2 
fffff80001039ef8, parameter3 0000000000000002, parameter4 0000000000000000."

Seems to work OK though under IOMeter.   As soon as I start HDTune 
though I get a "Read Error" popup from HDTune followed by a BSOD.

I can reproduce that, even after I thought I'd fixed it :)

Looking into it now.

Fixed it. There's some more things I want to test before I do another
binary release, but feel free to pull the source and compile it yourself
:)

Looks like there is another problem, here on my win 2008 x64 box the 
system tells me after every shutdown pv mode on boot that the last 
shutdown was unclean.

I wouldn't be too sure of that... I think that shutdownmon may be setting
the shutdown reason incorrectly, so that windows thinks that the last
shutdown wasn't right. It's inconsistent though.

I have a win2003 x64 box running just fine.  I think a lot of things 
depend on how you install the drivers.  I think the proper way is :

Boot into regular mode, run the installer. 
Go into device manager and manually install all the drivers. 
Set up the boot entry and reboot. 

If you just run the installer, and for some reason the drivers don't get 
installed, and you boot into the gplv mode and then manually install the 
drivers, it will most likely hose your system.  NEVER install the hard 
disk drivers in GPLV mode.  (unless it's for a secondary disk, or 
installing the virtual framebuffer).

Hm this is what i have done as far as i know.
May be i should uninstall and reinstall.
The problem is that even when i bootet to gplpv fine, all i wrote to 
disk is discarded on next boot (gplpv or no gplpv doesn't matter).
