i/o is very slow on FreeBSD dom0 with Xen-4.12 and Freebsd-12

Brian Buhrow
        hello.  I'm trying to get a FreeBSD-12 xen server up and running and
have run into the issue that i/o seems to be very slow for the dom0, which
is FreeBSD-12.0-stable, and Xen is xen-4.12.
        I followed the instructions for making FreeBSD a dom0 as written in
21.8 of the FreeBSD handbook.  All went well until I rebooted the machine
with the /boot/xen kern loading.  The dom0 boots, but takes about 2 hours
to get to the login prompt and, on the console, when ever I press
control-t, it says what ever process is currently running is in biord.
I'm familiar with NetBSD and how to make it run xen, and am familiar with
FreeBSD as well.  Stil, I'm sure I'm doing something wrong that's simple,
or, I missed some instruction that will seem obvious in retrospect.
If anyone can help me shed light on the trouble, that would be great!
Below are my /boot/loader.conf and a transcript of a sample boot.
Note that it took about  2 hours to get from the initial loading of the
kernel to the getty error messages.
-thanks
-Brian

Thanks for testing it out. What you do is correct, I think there's
either an issue in Xen or the firmware.

Any reason to force the clock source to HPET? Not that's it's wrong,
I'm just curious about why you need that.

Can you change dom0=pvh to dom0=pvh,verbose and also add
iommu=verbose,debug and sync_console and post the boot log again.

There's no need to wait for 2h, just post what you get up to the point
where the box freezes.

The above timeouts point out that at least the usb controller is not
working properly. Let's see if we can get more data with the new
options on the command line.

Thanks, Roger.

Re: i/o is very slow on FreeBSD dom0 with Xen-4.12 and Freebsd-12

Brian Buhrow
        hello.  Thanks for the response on this issue.  I tried forcing the
clock source to hpet0 because I initially thought my problem was that the
dom0 wasn't getting a reliable clock source and therefore was getting
"stuck" waiting for clock ticks.  I've turned that switch off for the
moment, since I don't think that's the problem.
In any case, below is the output of the boot log up until the system
becomes extremely slow.  I hope this is a simple issue.
-thanks
-Brian

Re: i/o is very slow on FreeBSD dom0 with Xen-4.12 and Freebsd-12

Brian Buhrow
In reply to this post by Brian Buhrow
        hello.  Another data point on this issue.  It appears the problem may
be with the onboard IDE controllers, or, possibly, the way interrupts are
handled.  If I switch the BIOS to enable ahcisata mode instead of IDE mode
for the SATA controllers, things boot more quickly, but the FreeBSD kernel
is unable to talk to the hard drives.  The ahci channels time out and we
get stuck in an endless loop of CAM system retries.  
        When the BIOS is set to Enhanced IDE mode, the FreeBSD kernel can talk
to the drives, but the data rate is so slow as to be unusable.  
        When FreeBSD boots on bare metal it can talk to the ahci or IDE drives
without a problem.  This makes me think Xen is messing with the interrupt
handling of the IDE controller somehow.  Is it possible the BIOS sets
things up in a way that FreeBSD likes, but Xen does not?  Perhaps the
ioapic is programmed in a way that FreeBSD doesn't like?
-thanks
-Brian

Re: i/o is very slow on FreeBSD dom0 with Xen-4.12 and Freebsd-12

Brian Buhrow
        hello.  Following up on this issue yet again, I'm pretty sure I have
the hardware discussed in the link below.  I tried disabling interrupt
remapping as the article suggests, but that just makes matters worse.  As I
understand it, when FreeBSD is running as a dom0, it must have iommu
interrupt remapping enabled in order to function.  Should I conclude that
this hardware just cannot run FreeBSD as a dom0 or is there another work
around that I might use?
-thanks

PVH dom0 requires iommu DMA remapping. Interrupt remapping is not
mandated for PVH dom0.

Can you also post the log when booting with
iommu=verbose,debug,no-intremap?

Can you also try booting without the no-intremap option, and then
switch to the hypervisor console (Ctrl-A on the serial line) and
paste the output of the i the M and the z debug keys at the point
where FreeBSD freezes? (together with the full serial log)

I need to look deeper, I'm quite sure the issue is with Xen. There are
also some bugfixes for the iommu in Xen unstable, which I can try to
backport to the FreeBSD 4.12.1 Xen packages, albeit there have been a
lot of changes in the iommu code, so backporting might not be feasible
for some of them.

I'm leaving home today and will be on PTO until Tuesday, and I don't
expect to be able to look into this until then, sorry.

Thanks, Roger.

        hello.  Here is the log with no-intremap enabled.
And, thank you for the help.  I hope your PTO was refreshing.

Re: i/o is very slow on FreeBSD dom0 with Xen-4.12 and Freebsd-12

Brian Buhrow
In reply to this post by Roger Pau Monné
        Hello.  Here are the logs with remapping enabled, plus the i, m and z
xen console commands.
Here's hoping you can provide a fix soon!  Or, perhaps, a clue on how to
fix.
-thanks

Does the crash happen every time you boot with ioapic_ack=old?

This looks like a file system error, likely some corruption caused by
previous reboots?

Ie: I'm not sure this is caused by Xen or rather by underlying errors
in the filesystem. At least there are no hardware errors on the log
AFAICT.

Thanks, Roger.

Re: i/o is very slow on FreeBSD dom0 with Xen-4.12 and Freebsd-12

Brian Buhrow
        hello Roger.  Sorry, my bad.  I didn't even look at the cause of the
panic.   Rebooting the system caused it to come up clean after another pass
with fsck.  With the ioapic_ack=old argument, the system comes up right
away and is quite responsive.
        Can you explain how to select which argument to use on the command
line if the autoselection code doesn't work?

        Thank you for your help!

-Brian

Hm, it's not so much that the autodetection is wrong, AFAIK there's
some hardware issue with specific models that make the new ack method
not work properly. This is limited to very specific (and older)
models. Note that you might still see interrupt timeouts with the old
ack method.

I will try to figure out if there's any hardware errata that could be
related to this issue, and try to find a box to reproduce (this might
not be feasible since I'm not sure I have anything similar to your
hardware available).

Roger.
