RE: Problems with GPLPV 0.9.10 on XP Pro, STOP 0x0000007B

[James Harper]

I've just put up some instructions on running the windows debugger in
Xen to be able to get some output from the GPLPV drivers if they won't
boot.

Have a look at http://wiki.xensource.com/xenwiki/XenWindowsGplPv

If it doesn't make sense or if I've made a mistake then let me know, or
go ahead and correct it yourself.

James

GPLPV Drivers 0.9.11-pre4 hang during boot - Windows XP Pro SP2

[Sandro Sigala]

[-- Attachment #1: Type: text/plain, Size: 1650 bytes --]

Hello James,

thanks for the new instructions on operating the debugger.

I tested the latest version of the PV driver on a Ubuntu server (dom0) with
kernel:
-----------------------------------
Linux version 2.6.24-16-xen (buildd@yellow) (gcc version 4.2.3 (Ubuntu
4.2.3-2ubuntu7)) #1 SMP Thu Apr 10 14:35:03 UTC 2008 (Ubuntu 2.6.24-4.6-generic)
-----------------------------------

and hypervisor:
-----------------------------------
(XEN) Xen version 3.2.1-rc1-pre (buildd@buildd) (gcc version 4.2.3 (Ubuntu
4.2.3-2ubuntu7)) Fri Apr 11 01:13:51 UTC 2008
-----------------------------------

the machine is an AMD Dual-Core AMD Opteron Processor 1220 stepping 03

The DomU is a fresh install of Windows XP Professional (English), SP2,
with the .net 2.0 framework and 0.9.11-pre4 drivers installed.

Graphically, the DomU hangs during the booting process (the progress
bar is running forever).

Under WinDbg, the latest messages printed every 5 seconds are:
-----------------------------------
XenVbd     no_free_grant_requests = 0
XenVbd     aligned requests   = 0, aligned bytes   = 0
XenVbd     unaligned requests = 0, unaligned bytes = 0
XenVbd     interrupts = 1
XenVbd     no_free_grant_requests = 0
XenVbd     aligned requests   = 1, aligned bytes   = 512
XenVbd     unaligned requests = 0, unaligned bytes = 0
XenVbd     interrupts = 1
-----------------------------------

Full debug log messages attached.

Machine configuration is:
    http://www.sigala.it/gplpv/WINXPPRO_ENG2.cfg
dmesg output from dom0:
    http://www.sigala.it/gplpv/dmesg.txt
xm dmesg output from dom0:

Hello James,

was the information I sent one week ago enough to spot the problem?

Thanks,
Sandro

RE: GPLPV Drivers 0.9.11-pre4 hang during boot - WindowsXP Pro SP2

[James Harper]

I've only just gotten back to it - I tried upgrading my test machine to
3.3-unstable (Debian package) and it was breaking badly.

Two things I noticed:

1. you are using tap:aio - as a test, can you try using file: instead? I
have never gotten tap:aio working. If you've already tried this and
mentioned it to me then I apologise in advance :)

2. I'm wondering if there might be a race in the code that figures out
if the backend is 32 or 64 bits... I'll do some testing on that.

RE: GPLPV Drivers 0.9.11-pre4 hang during boot - WindowsXP Pro SP2

[James Harper]

Could you please try 0.9.11-pre5?

That would be 0.9.11 proper except that suddenly 'restore' isn't working
anymore, but if you could tell me if you problem is fixed or not then
that would be great!

Unfortunately I can't make a test: the "file:" access is broken in Ubuntu
Hardy, while it was working IIRC in Ubuntu Gutsy. On the other hand, the
"tap:aio" access is working perfectly in Hardy while was broken in Gutsy :)

I tried on the same hardware/software configuration with a new fresh install
of WinXPPro (to be sure that no older PV driver was present).

Unfortunately seems like to loop forever on a different part of the code:
---------------------------------------------------------------------------
XenPCI     IRP_MN_QUERY_CAPABILITIES (status = c00000bb)
XenPCI     IRP_MN_QUERY_PNP_DEVICE_STATE (status = 00000000)
XenVbd --- HwScsiStartIo (Still figuring out ring)
XenVbd     ring_detect_state = 0, operation = ff, id = 0, status = 0
XenVbd     ring_detect_state = 1, operation = 0, id = ff, status = 0
XenVbd --> HwScsiResetBus
XenVbd     IRQL = 22
XenVbd <-- HwScsiResetBus
XenVbd     Command = INQUIRY
XenVbd     (LUN = 0, EVPD = 0, Page Code = 00)
XenVbd     (Length = 36)
XenVbd     (Srb->Databuffer = 817abbc8)
XenVbd     Command = INQUIRY
XenVbd     (LUN = 0, EVPD = 1, Page Code = 00)
XenVbd     (Length = 255)
XenVbd     (Srb->Databuffer = 817abbc8)
XenVbd     Command = INQUIRY
XenVbd     (LUN = 0, EVPD = 1, Page Code = 80)
XenVbd     (Length = 255)
XenVbd     (Srb->Databuffer = 817abbc8)
XenPCI     IRP_MN_QUERY_DEVICE_RELATIONS (status = 00000000)
XenVbd --> HwScsiResetBus
XenVbd     IRQL = 22
XenVbd <-- HwScsiResetBus
---------------------------------------------------------------------------

After the last message no more messages are printed on the windbg console
while the progress bar is still running (so it's not a hang).

Please find attached the full debug log.

Thanks,
Sandro

Hmmm... well according to the logs the fact that it is tap:aio doesn't
seem to be a problem - it's past where it crashes on my system when I
try with tap:aio.

I have uploaded a version of xenvbd.sys with a whole load of debug
statements in it which should give me more of an idea about what is
going on.

I have uploaded xenvbd-xp-debug.zip to
http://www.meadowcourt.org/downloads, please put the xenvbd.sys file in
c:\windows\system32\drivers and reboot and send me the debug output from
that.

Thanks

James

Re: GPLPV Drivers 0.9.11-pre4 hang during boot - WindowsXP Pro SP2

Hi,

I did like you suggested but the debug output in not changing
much, apart of a few lines different... unless I made a mistake
but it's unlikely, I just replaced the xenvbd.sys file as you
suggested after installing the drivers and before rebooting.

Interesting enough, without the /GPLPV parameter Windoze is hanging
at a certain point.  I noticed this behavior also in the previous
-pre4 version of the drivers.  I attached a debug log also
in that situation.

Thanks,
Sandro

Re: GPLPV Drivers 0.9.11-pre4 hang during boot - WindowsXP Pro SP2

[Wayne Gong]

Hi James,

I meet this problem before but not in the same scenario.
I use WinPv driver WDF version and attach a lot of vbd and vif device, 
such as 4 disks and 8 NICs. After WinPv driver install correctly, reboot 
the vm. Vm cannot reboot correctly every times. And the debug log is 
very similar as Sandro provided. I change the backend bit width detect 
code as follow. In my test box, WinPv driver works ok till now. Please 
have a try if you are interested in it.

Thank you very much! If James will not able to reproduce the very same
situation, I will try to install the DDK toolkit and compile myself the
drivers and do some experiments.

That patch appears to be to your wdf version of the code... can you give
me a summary of what the change you made is?

At a guess, the difference to the original code is that you are doing
two separate notify's, and a KeMemoryBarrier after each. Can you tell my
why the barrier is required?

I just noticed that the for() loop will never actually do anything as
req->nr_segments is initialised to zero... that's the same in my current
code too! I wonder how long that has been a problem for? I'll change my
code to initialise nr_segments to the maximum.

Yes, as you mentioned, there are only two difference. When I meet the 
bug, I have no idea to deal with it. So I try several method and times 
to fix it. After I changed the code up to the patch as I send to you, it 
works fine. And till now I am not very such whether this bug has been 
fixed. So I this patch just a try and I cannot explain it exactly even 
today.

My bad... I just looked at the winxp\i386 directory and the xenvbd.sys
in there is too old... I probably recompiled it for 2k3 by mistake.

I have just recompiled and uploaded the correct version. Sorry for
giving you the run around. Hopefully we'll get to the bottom of this
yet!

Do you have any timestamps to go with your logs? Don't worry about
resubmitting these ones but on any future ones it would be useful.

It looks like requests being put on the ring are not being actioned...
maybe we are corrupting something somewhere.

Looking at this bit of the logs:

"
XenVbd --- HwScsiStartIo (Still figuring out ring)
"

That 'Still figuring out ring' bit means that we got a request before we
had detected whether we were talking to a 32 or 64 bit ring, so we told
windows to give us the request back again later when we were ready. I
haven't seen that before in my logs, so something about your system
means that windows is giving you a request at an earlier point than my
test systems...

Then we see this:

"
XenVbd     ring_detect_state = 0, operation = ff, id = 0, status = 0
XenVbd     ring_detect_state = 1, operation = 0, id = ff, status = 0
"

Which means that the first response we got back had operation ff which
is what we expect, but the second one had operaton = 0 and id = ff which
means that the ring is out of alignment and we must be using the
opposite ring size (64 bits in this case).

Originally I thought that maybe Windows wasn't re-issuing the original
request, but obviously it is:

"
XenVbd --> HwScsiStartIo PathId = 0, TargetId = 0, Lun = 0
XenVbd     SRB_FUNCTION_EXECUTE_SCSI
XenVbd     Command = READ/WRITE
XenVbd --> XenVbd_PutSrbOnRing
XenVbd <-- XenVbd_PutSrbOnRing
"

But then it is never getting a response so it resets the bus:

"
XenVbd --> HwScsiResetBus
XenVbd     IRQL = 22
XenVbd <-- HwScsiResetBus
"

I wonder if it is a problem under XP... I'll see what I can do about
setting up a new XP test environment (my old one broke :)

Otherwise, I'm out of ideas for the moment.

RE: GPLPV Drivers 0.9.11-pre4 hang during boot - WindowsXP Pro SP2

[James Harper]

I've re-installed XP on my test machine and it works fine, so it's
obviously related more to your server than XP.

Did you get the DDK downloaded? I'd just enabled a heap of the debug
statements in there and add more and see what you can come up with.

I will do it ASAP, just 2 questions:

1) I will try to recompile the code using also the patch suggested by Wayne.
What is the HG revision of the code that matches with the 0.9.11-pre5
release? Are there any tags? (I'm used to SVN but not to the HG VCS, so maybe
I overlooked something...)

2) I tried in the past to put under stress the VMs with some benchmarks,
but unfortunately most of them are more Graphics-focused than
disk, net, cpu, memory focused.  Do you have suggestions for some other
software?

Thanks,
Sandro

Quite a while back I moved from using the newer WDF to using WDM. The
reasons for this were:
. I wanted to be able to use the drivers in textmode setup (eg 'Press F6
to load OEM drivers')
. Andy Grover wanted to be able to use mingw32 to compile rather than
the DDK compiler, which would mean building under Linux would be a
possibility.
. Nobody was really sure about the compatibility of GPL and WDF.

Wayne's patch relates to the WDF stream, but if you look in scsiport.c
you should recognise the part where the patch would apply, his changes
are fairly small.

Someone has reported crashes under (I think) one of the network
benchmark tools, but I've not been able to reproduce it.

Have a look through the mailing list at what others are using for
benchmarking... I've suddenly got a mental blank trying to remember what
they are called!

RE: GPLPV Drivers 0.9.11-pre4 hang during boot - WindowsXP Pro SP2

[James Harper]

I just had a thought... do you have any physical block devices you could
use, eg an lvm partition?

That way we can remove any doubt about it being the tap:aio thing.

If you don't have a physical device, then please try using losetup to
create a block device from your file and then use that as the phy:
device.

Thanks

Hi,

I'm downloading the WDK monster + XPSP2 symbols and is taking ages :-(

I had the same idea yesterday and I tried "just in case", unfortunately
the behavior is the same...

I'll build another xenvbd.sys with some more debug stuff in it.

Okay, as before, please try the xenvbd-xp-debug.zip from the download
site.

That one should give some more output about the responses that have been
received from dom0.

Okay... well I can see that there are definitely no interrupts occurring
after the call to 'PutSrbOnRing'.

I've just made another change, this time the ring state will be forced
to 64 bit without doing the detection side of things. Please download
and try again. That will tell us if the ring detection code is crashing
the backend in some way.

I'll wait up a bit for your response, but it's 22:37 over here, so if
you don't hear from me after this then I've gone to bed :)

Well... that's just strange. The two dummy requests get processed just
fine, but the real ones don't, even when I remove the dummy requests
completely... At least that tells me where not to look :)

I'll look at it further tomorrow.

Thanks

I've just put another one up to try. Give it a go when you can and send
me the results. I'm running out of ideas though...

Thanks. Log attached as usual.

Later (tomorrow for you I guess) I will install the DDK stuff, do some
experiments and post the results.

Are you getting anywhere with this, or may latest xenvbd.sys?

I'd like to do another release soon, but would really like to find out
what is causing the hang you are seeing as you aren't the only one who
has reported it.

Thanks

James

Sorry, I had to do some other unexpected work, and I moved forward the DDK
experimentation.

Please find attached the new log.

Everything seems okay in that one too.

If you can spare the time, please now try replacing your xenpci.sys with
the file in xenpci-xp-debug.zip, and try it again. This will tell me if
dom0 is sending the request at all and we are dropping it for some
reason.

Thanks

James

Done. Thanks for the "off-line" debugging.

Hmmm... I think I can see the problem - XenPCI is getting IRQ 5, and IRQ
5 is being assigned to all the subsequent devices that XenPCI
enumerates, and due to the slightly dodgy way I dish out interrupts to
other devices this maybe isn't working. I should probably have spotted
that earlier but I wasn't looking for it!

I'll see if I can come up with a fix of some sort, hopefully I'll have
something in a few minutes.

Btw, on my test machines, XenPCI always seems to get IRQ 28 and the
other devices all get IRQ 11. Any idea why yours would all be getting
IRQ 5? My guess would be that you don't have APIC enabled, or that you
didn't have it enabled when you first installed. Either way, it's a bug
for the GPLPV drivers to behave this way so I'll fix it. I just hope
there are enough interrupts to go around!

Thanks

James

Great!

Confirmed, I have APIC disabled in the VM (also while installing), because
in the past this caused strange problems with the older Xen versions.  Since
then I always left it disabled for safety, but I guess it's now safe...

Okay I've changed xenpci to not assign out the same irq to it's devices
as it gets from pci. Please get the xenpci-xp-debug.zip and give it
another go. I've given it a quick test and it doesn't seem to break
anything...

Congratulations, it works! ;-) (Both with apic=0 and apic=1).

I'm logging all the messages but it's quite slow, a lot of:
---
Mon Jul  7 12:29:51.305 2008 (GMT+2):
Mon Jul  7 12:29:51.505 2008 (GMT+2): XenPCI <-- EvtChn_Interrupt
Mon Jul  7 12:29:51.505 2008 (GMT+2):
Mon Jul  7 12:29:51.806 2008 (GMT+2): XenPCI --> EvtChn_DpcBounce
Mon Jul  7 12:29:51.806 2008 (GMT+2):
Mon Jul  7 12:29:52.036 2008 (GMT+2): XenPCI     Calling interrupt vector 33
Mon Jul  7 12:29:52.036 2008 (GMT+2):
Mon Jul  7 12:29:52.236 2008 (GMT+2): XenPCI <-- EvtChn_DpcBounce
---

I will send it when the debugging output is completed.

No need, if it's working then that's fine, the debug output will just
tell me what I already know.

I'll do another pre-release, probably tomorrow.

Thanks for your patience!
