I have a range of test images that I boot on a regular basis for
qemu-system-sparc64 with success. Can you provide the full command line,
QEMU version, and the output of the panic?


ATB,

[Ajallooiean Hossein]

Thanks for getting back to me so quickly.

I can boot Sparc64  -- ONLY when using the qemu from package manager. supposedly version 2.5

but when building it myself (as i have some additions) - im getting this kernel error:

https://pastebin.com/9XjdrUat


I am compiling qemu by myself and am using the following cmd to run it:


/Downloads/qemu-2.9.0-rc4/sparc64-softmmu$ ./qemu-system-sparc64 -M sun4u -m 196 -kernel /home/nihosa/Downloads/kernel4.10.11.sparc64 -hda /home/nihosa/Downloads/debian-9.0-sparc64-NETINST-1.qcow2 -nographic -L pc-bios


If you have it running, could you please send me your kernel/image for testing?

Thanks a lot
Hoss

Hmmm possibly not enough memory - have you tried using -m 256 or -m 512
at all? Also currently you'll need to boot with -nographic as there is
an issue with the bochs_drm driver at the moment.

Can you share your configure options and the final output (displaying 
CFLAGS, QEMU_CFLAGS and which features enabled)

Can you try recompiling with --disable-tcg-interpreter then retesting 
your kernel?

Thanks,

Phil.

Sanity check -- if you build a purely upstream QEMU without any
of your additions does it still have this kernel error?

Re: [Qemu-devel] Help needed: Sparc 64, kernel panic

[Ajallooiean Hossein]

Ive downloaded the rc4 link you posted for 2.9 and am using that. - vanilla qemu

And am getting the error with that version.

Kindest regards

I've just uploaded my latest kernel build and .config here for you to test:

https://www.ilande.co.uk/tmp/qemu/sparc64-kernel/vmlinux
https://www.ilande.co.uk/tmp/qemu/sparc64-kernel/.config

Can you also confirm your host architecture and the compiler/version you
are using?

Re: [Qemu-devel] Help needed: Sparc 64, kernel panic

[Ajallooiean Hossein]

[-- Attachment #1: Type: text/plain, Size: 2815 bytes --]

Thanks for the files and the notes.

I am attaching my config-host file for you. I'm on x86_64, running Linux 64, Ubuntu 16.04.2 LTS

so, i can also boot like you do - this worked before as well. btw, if you try to install that to a disk, itll not be able to as youll need to define memory for it.

The problem is after i install the iso on the qcow2 disk and then try to boot qemu-system-sparc64.

so here is the steps to reproduce the issue:
1- create a qcow2 image : debian-9.0-sparc64-NETINST-1.qcow2
2- download debian image: debian-9.0-sparc64-NETINST-1.iso
3- install the OS on dIsk
i use the below command line to do it:

./qemu-system-sparc64 -cdrom /home/nihosa/Downloads/debian-9.0-sparc64-NETINST-1.iso -hda /home/nihosa/Downloads/debian-sparc.qcow2 -nographic -boot d -L pc-bios -m 200

i guess i dont have to define a kernel in the above code???

4- installation goes all well.
5- i try to run the new disk image: - here i add kernel as if i dont add it ill get the below:

https://pastebin.com/cFwrX9E9

6- so here im adding kernel: - the one that you provided
./qemu-system-sparc64 -hda <PATH>/debian-sparc.qcow2 -nographic -L pc-bios -m 200 -kernel <PATH>/vmlinux

7 -i get a this error now: - with your kernel
https://pastebin.com/Z0ah7nji

8- if i use the newest kernel: available/stable i get this error: - i am compiling the kernel myself
https://pastebin.com/6EDYiaxX


9- and if i use a kernel that was working with 2.7 - i get this:
https://pastebin.com/bWbsrKCm


Thanks
Hoss

I've just done a test install with
https://people.debian.org/~glaubitz/debian-cd/2017-03-24/debian-9.0-sparc64-NETINST-1.iso
and I didn't see any errors similar to the ones you mention (although I
did have to blacklist the bochs_drm module upon boot).

The resulting qcow2 image can be found temporarily at
https://www.ilande.co.uk/tmp/qemu/sparc64-kernel/deb90.qcow2.xz and you
can launch it with:

./qemu-system-sparc64 -hda deb90.qcow2 -m 256 -nographic

Username and password are both root.

Re: [Qemu-devel] Help needed: Sparc 64, kernel panic

[Ajallooiean Hossein]

Hi Mark,

Thanks a lot for this. - it did work! 

So, now im wondering how did you install the iso on disk?

would you mind sharing your command line for the install please? and hacks if any

i am now able to install and boot, but my boot hang after this line "[   22.559491] [TTM] Initializing pool allocator" - inside user space. - I did blacklist bochs_drm for installing as such "-append 'modprobe.blacklist=bochs_drm'".

also, i have a couple of questions if you dont mind responding to them. - ill appreciate this a lot:
1- did you use virtio for your install? i.e. not using the "-cdrom" command and blacklisting the pata_cmd64x and also providing your own virtio device (/dev/vdb)?
    - i used this link for hints on how to install with virtio http://tyom.blogspot.ch/2013/03/debiansparc64-wheezy-under-qemu-how-to.html

2- i see that you used ext3 for your OS install, isnt that slower than ext4? -again im referencing this: http://tyom.blogspot.ch/2013/03/virtio-performance-and-filesystems.html

3- also, im noticing that you didnt define root=/dev/sda or root=/dev/vda1 for when your running qemu. and when im running your image i have to do that, otherwise ill get to the initramfs only. is there a trick behind this?

4- i dont see you defining a kernel and initrd? is there a reason for this? if i just use your cmd line, ill get this: also, are you extracting the kernel and initrd from the image or the iso?

and I didn't see any errors similar to the ones you mention (although I
did have to blacklist the bochs_drm module upon boot).

The resulting qcow2 image can be found temporarily at
https://www.ilande.co.uk/tmp/qemu/sparc64-kernel/deb90.qcow2.xz and you
can launch it with:

./qemu-system-sparc64 -hda deb90.qcow2 -m 256 -nographic

Hi Mark

Sorry for pinging so early.

Im just wondering if youve had time to go over my email below.

Any help would be greatly appreciated.

Thanks

Hi Mark,

Thanks a lot for this. - it did work!

So, now im wondering how did you install the iso on disk?

would you mind sharing your command line for the install please? and hacks if any

i am now able to install and boot, but my boot hang after this line "[   22.559491] [TTM] Initializing pool allocator" - inside user space. - I did blacklist bochs_drm for installing as such "-append 'modprobe.blacklist=bochs_drm'".

also, i have a couple of questions if you dont mind responding to them. - ill appreciate this a lot:
1- did you use virtio for your install? i.e. not using the "-cdrom" command and blacklisting the pata_cmd64x and also providing your own virtio device (/dev/vdb)?
    - i used this link for hints on how to install with virtio http://tyom.blogspot.ch/2013/03/debiansparc64-wheezy-under-qemu-how-to.html

2- i see that you used ext3 for your OS install, isnt that slower than ext4? -again im referencing this: http://tyom.blogspot.ch/2013/03/virtio-performance-and-filesystems.html

3- also, im noticing that you didnt define root=/dev/sda or root=/dev/vda1 for when your running qemu. and when im running your image i have to do that, otherwise ill get to the initramfs only. is there a trick behind this?

4- i dont see you defining a kernel and initrd? is there a reason for this? if i just use your cmd line, ill get this: also, are you extracting the kernel and initrd from the image or the iso?

I simply went for something along the lines of:

./qemu-system-sparc64 -hda deb90.qcow2 -cdrom
debian-9.0-sparc64-NETINST-1.iso -boot d -nographic

i.e. no virtio devices and using the in-built device emulation. I do
have some alpha patches that add virtio support to OpenBIOS but they are
definitely not ready for production yet.

> i am now able to install and boot, but my boot hang after this line "[   22.559491] [TTM] Initializing pool allocator" - inside user space. - I did blacklist bochs_drm for installing as such "-append 'modprobe.blacklist=bochs_drm'".

Once I installed the image, I restarted QEMU as normal but this time
booting from the qcow2 image i.e.

./qemu-system-sparc64 -hda deb90.qcow2 -cdrom
debian-9.0-sparc64-NETINST-1.iso -nographic

Then at the SILO "boot: " prompt I typed:

Linux modprobe.blacklist=bochs_drm

That got me to a terminal login at which point I created the following
file as /etc/modprobe.d/bochs_drm.conf:

blacklist bochs_drm

I then did an update-initramfs rebooted as normal, since with the module
blacklisted there is no need to enter any custom parameters at the SILO
boot prompt and I can simply hit Enter.

No, it just seems to work for me with the inbuilt CDROM? However if you
switch to using my image with virtio then you'll have to tweak
/etc/fstab to use /dev/vda* rather than /dev/sda* devices and rebuild
the initramfs once again.

Right - all you need to do here is hit Enter and boot will continue.
Since I'm not using virtio I'm letting SILO do the work here. Once
you've blacklisted bochs_drm and rebuilt the initramfs with everything
setup then you should be able to copy them from the resulting image and
boot them directly in QEMU using -kernel and -initrd.

[Qemu-devel] Help needed: Sparc 64, kernel panic

[Siavash Katebzadeh]

Hi,

I can reproduce this panic using debian-7.8.0 image. I’m getting this segmentation fault:

[   24.846406] busybox[1]: segfault at f78a000c ip 00000000f77ab0ac (rpc 00000000f77ab090) sp 00000000ffd95a50 error 30001 in libc.so.6[f76f0000+174000]

I found out the commit with 7268adebfda6548b8ae6865dc8337f116a5d266d hash is broken.
Could you please take a look at this commit? Thanks.

Siavash.

I've just tried locally with git master and I can't reproduce this at
all? I'm booting like this:

./qemu-system-sparc64 -cdrom debian-7.8.0-sparc-netinst.iso -nographic
-boot d

and I get all the way to the installer. If I drop to a busybox shell
then I don't see any errors? Please can you give the full command line
and information about your host OS and architecture.

Please make sure that you CC the qemu-devel list, particularly as I
won't be around for several days. There have been several fixes in 2.9
that could be related to this - do you still see the same issue with the
latest 2.9 release?

My mistake.
Yes I Already tried qemu-2.9.0.rc5. Same error happens.
