Re: [Qemu-devel] qemu-user[armel/mips] and debian-rootfs

[Lisandro Damián Nicanor Pérez Meyer]

Hi! First of all, sorry for breaking the thread [0] (although it is too old 
maybe).

[0] 

As I have stumbled upon this bug, I would like to know if there is something I 
can do to try to help fixing it. I have never seen qemu's code and I am really 
a newbie to it, so any pointer would be higly appreciated.

Kinds regrads, Lisandro.

I have clearly not been verbose enough, so I'll better try to solve that :-)

The problem is the following: once I create a chroot, I copy /usr/bin/qemu-
mips-static to $CHROOT/usr/bin and then chroot $CHROOT.

Now if I do run touch on any file, I get:

root@debian:/# touch tito
/usr/bin/touch: setting times of `tito': Level 2 not synchronized

Once again, any pointer to try to debug it would be highly appreciated.

Also I would like to thank josch who has been helping me a lot with this :-)

Kinds regards, Lisandro.

You can run /usr/bin/qemu-mips-static -strace /bin/touch tito to see 
what syscall are being run, and what gives the level2 error.


Some basic details should also be provided for good bugreport:

1. version of qemu being used (a release or latest git?)
2. host linux version (2.6.?)  and architecture (i386, x86_64, ?)
3. version of debian used to create chroot (lenny. squeeze, sid, ??)

Ok, I missed these patches. Will adjust the linux-user patchset to include
these patches if no bugs found in them.

Thanks Riku! This bug has already been solved by Wesley Terpstra:



I have patched the debian package, rebuilt and use it perfectly :-)

Kinds regards, Lisandro.

Just a heads up---if you only use my original patch, mipseb still
won't be able to run 'make'.
My final patchset (sent as a series of 6 patches) resolves this in
addition to the other problems.

And there you solved my last problem :-)

Thanks!

I have tested this by getting the source code, creating a Debian package as if 
it were a NMU of the last version in Sid (although with different sources, but 
fair enough for testing I guess) and I can say it works :-)

I have both been able to setup a rootfs for my Ubiquiti RouterStation Pro and 
also compiled some qt stuff in a chroot in my desktop :-)

Kinds regards, Lisandro.
