[PATCH 0/7] kernel-yocto: conslidated pull request

[Bruce Ashfield]

Hi all,

Now that 4.12 + headers are in the tree, this is the next (and possibly final)
around of -stable updates for the active kernels.

I've built and booted them on all four architectures. But as usual, this is a
lot of combinations to confirm.

The 4.12 update doesn't specifically address the kernel traces that RP has
been seeing, but it also doesn't regress things here. I'd be interested to
know if they help/hinder in the search to find the root cause.

I'll of course continue to track it down myself.

I also have some functionality fixes as well as configuration updates as part
of this update.

Cheers,

Bruce

[PATCH 1/7] linux-yocto/4.10: fix aufs build

[Bruce Ashfield]

The aufs patches were out of sync with the latest upstream and hence
didn't build against 4.10.

With this update, we are once again building and up to date with the
upstream repo.

Hi Bruce,

I didn't get these commits in linux-yocto-4.10 git tee? Did you forget to push
or I missed something?

Thanks,
Kevin

[PATCH 4/7] linux-yocto/4.12: silence qeumarma9 config warnings

[Bruce Ashfield]

When building the qemuarma9 BSP, we get the following warnings:

 ---------- CONFIG_VGA_CONSOLE -----------------
 Config: CONFIG_VGA_CONSOLE
 From:
  tmp/work-shared/qemuarma9/kernel-source/.kernel-meta/configs/standard/arm-versatile-926ejs/bsp/qemuarma9/qemuarma9.cfg
 Requested value:  # CONFIG_VGA_CONSOLE is not set
 Actual value:

 ---------- CONFIG_USB_ISP1760_HCD -----------------
 Config: CONFIG_USB_ISP1760_HCD
 From:
  tmp/work-shared/qemuarma9/kernel-source/.kernel-meta/configs/standard/arm-versatile-926ejs/bsp/qemuarma9/qemuarma9.cfg
 Requested value:  CONFIG_USB_ISP1760_HCD=y
 Actual value:

Both of these options no longer need to be in the BSP fragments
for qemuarma9, we fix them with these meta data changes:

  a2edeff915b9 qemuarma9: remove USB_ISP1760_HCD
  5f76e8f64fa5 qemuarma9: drop VGA console disable

I ran these on the autobuilder. We did see:

https://autobuilder.yocto.io/builders/nightly-ppc/builds/465

which is the latest 4.12 kernel and the latest qemu hanging with no
boot output (but the pid did appear).

So we're still seeing something odd with ppc occasionally. Why? Don't
know :(

Cheers,

Richard

The only thing crappier than IDE support, is the PPC platforms that
qemu supports for system emulation.

I'll continue to try and track down the issues.

Hi Bruce,

We had a locked up qemuppc lsb image and I was able to find backtraces
from the serial console log (/home/pokybuild/yocto-autobuilder/yocto-
worker/nightly-ppc-lsb/build/build/tmp/work/qemuppc-poky-linux/core-
image-lsb/1.0-r0/target_logs/dmesg_output.log in case anyone ever needs
to find that). The log is below, this one is for the 4.9 kernel.

Failure as seen on the AB:
https://autobuilder.yoctoproject.org/main/builders/nightly-ppc-lsb/buil
ds/1189/steps/Running%20Sanity%20Tests/logs/stdio

Not sure what it means, perhaps you can make more sense of it? :)

Cheers,

Richard

Very interesting.

I'm (un)fortunately familiar with RCU issues, and obviously, this is
only happening under load. There's clearly a driver issue as it
interacts with whatever is running in userspace.

 From the log, it looks like this is running over NFS and pinning the
CPU and the qemu ethernet isn't handling it gracefully.

But exactly what it is, I can't say from that trace. I'll try and do
a cpu-pinned test on qemuppc (over NFS) and see if I can trigger the
same trace.

Looking at the logs I've seen I don't think this is over NFS, it should
be over virtio:

"Kernel command line: root=/dev/vda"

I'm also not sure what this might be. I did a bit more staring at the
log and I think the system did come back:

So for a while there the system "locked up":

Process killed - no output for 1500 seconds. Total running time: 1501 seconds.

AssertionError: 255 != 1 : login command does not work as expected. Status and output:255 and ssh: connect to host 192.168.7.2 port 22: No route to host

then the system seems to have come back. All very odd...

Richard

I'd expect after the stall that it would come back. But it
is good news that it isn't over NFS, since that would make things
harder to reproduce.

There's some sort of cpu intensive task -> virtio that is not
allowing softIRQd to run within limits.

We could back off the warning and increase the limit, but that
can cause more serious problems down the road.

After letting my qemuppc run with a hard cpu loop for 5 days, I did
finally manage to get a RCU stall.

I still don't have a root cause, but I can confirm that I saw this
with my 4.12 kernel as well.

I'm still trying to get a solid reproducer for this, but I'm now
going down the route of isolating different parts of the system.

I was looking at:

https://autobuilder.yocto.io/builders/nightly-ppc-lsb/builds/475/steps/Running%20Sanity%20Tests/logs/stdio

And I thought that this was related to the switch of the cdrom to
be virtio backed, but looking at the command line:

tmp/work/x86_64-linux/qemu-helper-native/1.0-r1/recipe-sysroot-native/usr/bin//qemu-system-ppc 
-device virtio-net-pci,netdev=net0,mac=52:54:00:12:34:02 -netdev 
tap,id=net0,ifname=tap0,script=no,downscript=no -drive 
file=/home/pokybuild/yocto-autobuilder/yocto-worker/nightly-ppc-lsb/build/build/tmp/deploy/images/qemuppc/core-image-lsb-sdk-qemuppc.ext4,if=virtio,format=raw 
-show-cursor -usb -device usb-tablet -device virtio-rng-pci -serial 
tcp:127.0.0.1:48509 -pidfile pidfile_13726 -machine mac99 -cpu G4 -m 256 
-serial tcp:127.0.0.1:40895 -snapshot -kernel 
tmp/deploy/images/qemuppc/vmlinux--4.9.46+git0+f16cac5343_cf9a7dd9f4-r0.2-qemuppc-20170912090305.bin 
-append root=/dev/vda rw highres=off  mem=256M 
ip=192.168.7.2::192.168.7.1:255.255.255.0 console=tty console=ttyS0 
console=tty1 console=ttyS0,115200n8 printk.time=1

That doesn't come into play here, so I've stopped mining the virtio
back end for the moment .. if you have

But since this does happen in 4.12 and 4.9, I can't shake the logic
that it has to do with some different way we are now invoking qemu
that is triggering and existing kernel issue.

.. but again, back to not seeing that -cdrom change in the command
line.

Do you know of any other qemu parameter changes that are fairly recent ?
I'm not seeing any, but wanted to check.
