Public bug reported:
This bug is reported against the 3.0 release.
I noticed that the GCC test gcc.dg/torture/tls/tls-test.c is failing
when run in user-mode qemu for nios2 target. The problem appears to be
that the thread-related syscalls are unimplemented in qemu. Here is
output from running with -strace:

Note that set_robust_list and clone are reported as unimplemented.
I've reported the problems with the signal syscalls separately here.

Note that set_robust_list and clone are reported as unimplemented.
I've reported the problems with the signal syscalls separately here.

One thing that would help in better supporting NIOS is if we could add
support for building linux-user tests for it in test/tcg. For this we
need a distribution that ships a decent cross compiler or create a
docker recipe that packages it up so we can build and run the tests.
Are you just building GCC straight from source or can you point to a
recommended location for a decent packaged gcc?

Hi,
tl;dr Nios II linux-user seems pretty broken
Following up on some mailing list queries about the state of Nios II
Thomas pointed out that buildroot could build cross-compilers for the
architecture. As a quick experiment I've enabled a docker based
buildroot and turned on tests/tcg for it.
The results are not very encouraging as both linux-test and test-mmap
fail although (impressively?) testthread passes.
The test-mmap failure looks like some sort of argument mangling
failure as arg6 of target_mmap looks negative/big and hence causes the
mmap to fail. I tried messing with the #ifdef mangling logic in
do_syscall1 but failed to get it working.
The linux-test failure seems like a missing lseek system call but I
have no doubt there are others given the bug reports on list.
This series includes a hack to min uname which we can't really merge.
This is because buildroot is focused on building system images so sets
the glibc minimum kernel version to whatever it builds for the system
image. I leave the problem of programatically tuning the
qemu_nios2_10m50_defconfig to build a general purpose glibc to whoever
wants to take this forward.
As I'm not particularly interested in this architecture I don't intend
to spend any more time on this. Given how broken linux-user is I
suspect most users of QEMU's Nios 2 emulation use softmmu. If there is
interest in fixing up linux-user then the docker and test/tcg patches
can be included when the fixups are sent to the list. I would argue
that any linux-user target should at the very least pass all of
tests/tcg/multiarch - it's not super comprehensive but it's all we
have at the moment. Perhaps we should consider deprecating the
obviously less used linux-user targets?

We can build some more cross-compilers using buildroot. This base
system contains simply the minimum number of tools required for
buildroot to work. We also download and unpack the buildroot source
tree as that will be common for all system deriving from it.

This is to work around the limitations of the buildroot
qemu_nios2_10m50_defconfig which sets the base kernel version for
glibc.

Now we have a docker image with a nios2 compiler we can add the bits
to build our TCG tests.
Current failures:
testmmap - fails in check_file_fixed_eof_mmaps due to inversion of offset
linux-test - unimplemented lseek (probably others as well)

I have no objection. Perhaps you could ask NiosII Maintainers (cc).

If that's needed, so be it. The Linux 3.19 was required because some
obscure ABI change happened at that point.

Doh.. I had cccmd = scripts/get_maintainer.pl --nogit-fallback but of
course as I didn't actually touch an nios2 files it didn't include them.

Title:
unimplemented thread syscalls in nios2 user-mode emulation
Status in QEMU:
New
Bug description:
This bug is reported against the 3.0 release.
I noticed that the GCC test gcc.dg/torture/tls/tls-test.c is failing
when run in user-mode qemu for nios2 target. The problem appears to
be that the thread-related syscalls are unimplemented in qemu. Here
is output from running with -strace:

Note that set_robust_list and clone are reported as unimplemented.
I've reported the problems with the signal syscalls separately here.

I also use "git blame" to know who to bother ;)

I don't think so - it's an artefact of the way the buildroot toolchain
is built. But the real question which I address in the cover letter is
does nios2-linux-user get much use? I tried enabled tests/tcg for it and
it fails rather badly.

I used it around 2.10 and it worked for me.

If you need a Nios II GNU/Linux toolchain, I think the most recent
CodeBench Lite release will work:
https://sourcery.mentor.com/GNUToolchain/subscription42545
We're planning on adding user-mode QEMU to the upcoming 2018.11
release.... that's actually what I've been testing it for. Results on
the GCC testsuite actually don't look too bad, but I have a patch I
haven't submitted yet that's required to make the GDB stub work, and
there are a lot of GDB test failures I haven't triaged yet.

Title:
unimplemented thread syscalls in nios2 user-mode emulation
Status in QEMU:
New
Bug description:
This bug is reported against the 3.0 release.
I noticed that the GCC test gcc.dg/torture/tls/tls-test.c is failing
when run in user-mode qemu for nios2 target. The problem appears to
be that the thread-related syscalls are unimplemented in qemu. Here
is output from running with -strace:

Note that set_robust_list and clone are reported as unimplemented.
I've reported the problems with the signal syscalls separately here.

OK - I'm a little surprised given the failures I saw in our own
test/tcg/multiarch but it's totally possible that:
- the buildroot toolchain if foobar
- the (ancient) tests need tweaking
but it would be nice if we get to a point that QEMU's internal
linux-user tests also pass.

When you do post the gdb patch feel free to CC me as I've poked around
in that before.

I've just build 2.10.2 (with a patch for memfd and this one) and get the
same failures on the tcg/tests tests. What testing where you running?

Apparently multi-stage builds are meant to help:
https://docs.docker.com/develop/develop-images/multistage-build/#name-your-build-stages
It's still a little sub-optimal compared to binary builds but it will do
if we care about supporting every guest architecture with tests. I only
picked nios2 as a random example.

The QEMU project is currently considering to move its bug tracking to another system. For this we need to know which bugs are still valid and which could be closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch the state back to "New" within the next 60 days, otherwise this report will be marked as "Expired". Or mark it as "Fix Released" if the problem has been solved with a newer version of QEMU already. Thank you and sorry for the inconvenience.
** Changed in: qemu

Title:
unimplemented thread syscalls in nios2 user-mode emulation
Status in QEMU:
Incomplete
Bug description:
This bug is reported against the 3.0 release.
I noticed that the GCC test gcc.dg/torture/tls/tls-test.c is failing
when run in user-mode qemu for nios2 target. The problem appears to
be that the thread-related syscalls are unimplemented in qemu. Here
is output from running with -strace:

I noticed that the GCC test gcc.dg/torture/tls/tls-test.c is failing
when run in user-mode qemu for nios2 target. The problem appears to
be that the thread-related syscalls are unimplemented in qemu. Here
is output from running with -strace:
