Yes, qemu's linux-user emulation layer doesn't currently support any of
the posix timer syscalls.

Any idea how much work is involved to implement this?

A couple of days for somebody who knows what they're doing and has
a convenient test case.

Working on it.

[Qemu-devel] [Bug 1042388] Re: qemu: Unsupported syscall: 257 (timer_create)

[Riku Voipio]

Implementing timer_create along is probably not enough, one would have
to implement rest of the related syscalls:

       *  timer_create(): Create a timer.
       *  timer_settime(2): Arm (start) or disarm (stop) a timer.
       *  timer_gettime(2): Fetch the time remaining until the next expiration of a timer, along with the interval setting of the timer.
       *  timer_getoverrun(2): Return the overrun count for the last timer expiration.
       *  timer_delete(2): Disarm and delete a timer.

Convinient testcases for timer* syscalls exist apparently in ltp suite.

I have a fix for this. I can now successfully install ghc and compile
programs with it.

In the process of cleaning up the patch and working on a test for the
test suite.

Erik,

Is this patch available for public consumption? It doesn't seem to be
upstream.

[Predrag Radovic]

Until proper patch is available I'm using attached temp workaround.

After some testing GHC and produced executables appear to work correctly
in foreign arch chroot.

I'm sure there will be issues but I only need compilation to work in
foreign arch chroot because I will deploy produced executables to
Raspberry Pi anyway.

cabal-installing works too but I had to comment out anything related to
Template Haskell from (to be installed) packages.

versions:

qemu 1.4.1 (static build)
host: Linux proton 3.9.2-1-ARCH #1 SMP PREEMPT Sat May 11 20:31:08 CEST 2013 x86_64 GNU/Linux
foreign: Linux proton 3.9.2-1-ARCH #1 SMP PREEMPT Sat May 11 20:31:08 CEST 2013 armv6l GNU/Linux
chroot created from 2013-02-09-wheezy-raspbian.img
ghc 7.4.1-4+rpi1 armhf


** Patch added: "temp workaround to enable compilation and execution of GHC  and produced executables in foreign arch chroot"

I just tried it here on my system using:

    - QEMU compiled from git HEAD.
    - ghc 7.6.3-6 from Debian

and I was able to start compiling GHC from git. I didn't let it run to
completion because I only have my laptop available at the moment.

I suggest you try debugging some more and maybe try building something
smaller than GHC.

This my Debian system:

    $ uname -a
    Linux rolly 3.11-2-amd64 #1 SMP Debian 3.11.10-1 (2013-12-04) x86_64 GNU/Linux

I normally run my qemu chroot using schroot as follows:

    schroot -c armhf

If I need to install packages I schroot as root:

    schroot -c armhf -u root

In the chroot, I get:

    Linux rolly 3.11-2-amd64 #1 SMP Debian 3.11.10-1 (2013-12-04) armv7l
GNU/Linux

and as root I have successfully removed and installed ghc from the
Debian repositories.

Fixed upstream, thanks Eric! Marking as affecting Ubuntu, as even
trusty's qemu does not have that fix yet. For the record, lp:platform-
api uses posix timers for the sensor emulation, so running its tests
will reproduce this qemu problem (and verify its fix).

[Martin Pitt]

Unfortunately it is still not working with these two patches. The
"Unsupported syscall: 257" is gone, but now it fails on EINVAL. I attach
a little test C file which uses  a timer. It works fine on x86 and a
real arm machine, but under QEMU I get:

$ gcc -o timer_test -Wall  timer_test.c  -lrt
$ ./timer_test
Failed to create timer: Invalid argument
qemu: uncaught target signal 6 (Aborted) - core dumped
Aborted (core dumped)

So timer_create() does not actually seem to work? I tried some
variations like 50 ms, or using CLOCK_REALTIME instead of
CLOCK_MONOTONIC, all with the same result.

Thanks  for the test case Martin. Problem confirmed.

The issue is that timer_create allows a number of different callback
mechanisms and I had only implemented the one I need.

 Working on it now.

this is marked Fix Released in QEMU project, but comment #28 suggests
that commit f4f1e10a58cb5ec7806d47d20671e668a52c3e70 does not in fact
solve this bug.  If there is a set of patches upstream that does fix the
bug, please let me know and I'll pull them into trusty.  Thanks much!

The fix that was commited to the Qemu git tree fixed the original test
case I had. @pittit then found another test case that fails and I intend
to fix that when I find a good chunk of free time. Problem is I only
work on Wemu sporadically and it takes me quite a bit of time to get up
to speed when I return to work on it.

[Erik de Castro Lopo]

I've been looking at it over the last week or so and I have submitted a
patch toe the qemu-devel mailing list to fix another timer_create()
problem sometime in the last week.

Unfortunately the test case @pittit submitted is far harder to support
than the original test case. In this case the timer_create() syscall
gets passed pointers to functions and data in the target's address space
and I have not figured out how to handle that yet.

Didn't we discuss this on the list a while back? You're confusing
the libc API with the kernel syscall API here -- the kernel definitely
does not take a pointer to a function to call here. (The timer_create
manpage explicitly says that the SIGEV_THREAD functionality
is implemented in the C library, not the kernel.) You can see
this if you strace it:

clone(child_stack=0xb76e5494,
flags=CLONE_VM|CLONE_FS|CLONE_FILES|CLONE_SIGHAND|CLONE_THREAD|CLONE_SYSVSEM|CLONE_SETTLS|CLONE_PARENT_SETTID|CLONE_CHILD_CLEARTID,
parent_tidptr=0xb76e5bd8, {entry_number:6, base_addr:0xb76e5b70,
limit:1048575, seg_32bit:1, contents:0, read_exec_only:0,
limit_in_pages:1, seg_not_present:0, useable:1},
child_tidptr=0xb76e5bd8) = 12666
rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0
futex(0xb76d324c, FUTEX_WAKE_PRIVATE, 2147483647) = 0
timer_create(CLOCK_REALTIME, {0x984b098, 32, SIGEV_THREAD_ID,
{12666}}, {0x1}) = 0
timer_settime(0x1, 0, {it_interval={0, 0}, it_value={0, 50000000}}, NULL) = 0

Under the hood libc is creating a new thread with clone, and
what the timer_create() syscall gets passed is a struct including
the thread ID to be sent a signal when the timer expires (here
that's 12666).

So all you need to do is support SIGEV_THREAD_ID,
which I think doesn't require much more than copying
across the thread ID struct field.

(On the other hand that does mean that all programs which
use SIGEV_THREAD are by definition multithreaded, which
puts them into "this isn't supported" territory because of our
well known and longstanding threading issues.)

Patch which seems to at least make the test case work (tested with
i386-on-i386 linux-user): http://patchwork.ozlabs.org/patch/378769/

Unfortunately it doesn't work with armhf on amd64 linux-user.

Use the test program from comment #27 I get:

    > schroot -c armhf -- ./timer_test_armhf 
    About to call host's timer_create (0, 0x7fff6ee80720, 0x625b1f40)
    Host's timer_create returns -22
    Failed to create timer: Invalid argument
    qemu: uncaught target signal 6 (Aborted) - core dumped
    E: Child terminated by signal ‘Aborted’

(Yes I made very certain the schroot was using my freshly compiled
version of qemu-arm-static).

@erikd,

can you check whether this has been fixed in wily?

** Changed in: qemu (Ubuntu)

[Peter Maydell]

I finally got round to looking into why the test case from comment #27
worked on x86-64 guests and i386-guest-on-i386-host but not on arm-
on-x86-64. This turns out to be a wrong structure definition which meant
we weren't handling the 32-bit-guest-on-64-bit-host combinations
correctly. I've sent a patch:

http://patchwork.ozlabs.org/patch/665274/

I think this should tie up the last loose end in this bug report so once
it gets into master we can close it.
