Yes,

Long story short, nobody implemented SMP so far. :-)
Because SKAS3/0 we had a SMP implementation of TT mode.

In terms of UML implementing SMP means having multiple threads
that handle the userspace loop in arch/um/os-Linux/skas/process.c.

We could also do a poor man's SMP implementation first, where only user 
processes run in parallel.
IOW userspace() in arch/um/os-Linux/skas/process.c is still a single thread 
but it let's run up to N user space thread and only if the call into the 
kernel we degrade to UP.

Adding SMP is not extremely hard but it requires a lot of re-work of the UML 
core and introduces tons of new issues.

That said, volunteers are welcome!

Thanks,
//richard

Thanks a lot! I am wondering why the same compiler works when running
the test for a regular image. Maybe different compiler flags. Anyway
good to learn this.

Also one more slightly OT question, why is UML only doing UP ? Is it
extremely hard to do SMP for UML?

I also happen to notice Qemu has one thread per emulated core...

Without cpu_relax()/barrier()/volatile, the compiler can assume release_now
never changes, and thus may "optimize" the loop to an infinite loop.

Timers trigger also with preempt off, I forgot...
I think the cpu_relax() issues internally a barrier such that the
release_now variable is read again.
Can you try barrier() instead of cpu_relax()? I bet it works too.
Same if you mark release_now as volatile.

cpu_relax actually worked!

Any thoughts on why it helps? Even if its non-preemptive, I did
receive the timer interrupt, so I expected the variable to be set.

Not sure whether a cpu_relax() fixes the problem.
I guess the root of the problem is that UML is UP and non-preemptive. 
Therefore the loop is never interrupted.
To verify I asked for the full source.

[uml-devel] UML hangs with hrtimer test module

[Joel Fernandes <agnel.joel@gm...>]

Hi,

I wrote a kernel module to play with hrtimer subsystem and it hangs
with UML, Any ideas on why it may be hanging? It doesn't hang on any
of my other machines. Hopefully I'm not doing something stupid, but I
don't think I am..

It appears the timer handler does fire. However, the UML process is
continously doing a kill(SIGALRM) to the host, and the shell hangs.
Here's the continous strace output of UML's process at the time of the
hang: https://hastebin.com/ikehadapon.sql

To build UML, I do:
make ARCH=um x86_64_defconfig

UML kernel version is v4.16-rc4

Here's the module I'm loading:

static enum hrtimer_restart bigtimer_handle(struct hrtimer *timer)
{
        printk(KERN_ERR "timer fired 2\n");
        spin_lock(&il->biglock);
        spin_unlock(&il->biglock);

        release_now = 1;

        return HRTIMER_NORESTART;
}

void init_bigstr(struct bigstr *b)
{
        spin_lock_init(&b->biglock);
}

static int __init test_module_init(void)
{
        struct bigstr b1, b2;
        struct hrtimer *timer;

        release_now = 0;

        init_bigstr(&b1);
        init_bigstr(&b2);

        timer = &bigtimer;
        timer->debug = 1;

        hrtimer_init(timer, CLOCK_MONOTONIC, HRTIMER_MODE_REL);
        timer->function = bigtimer_handle;

        il = &b2;
        spin_lock(&b1.biglock);

        printk(KERN_ERR "Starting timer\n");
        hrtimer_start(timer, ns_to_ktime(50000ULL),
                      HRTIMER_MODE_REL_PINNED);

        while(release_now == 0);

        spin_unlock(&b1.biglock);
        return -1;
}


Thanks for any debug thoughts!
I'll also try to hook up gdb tomorrow and see if I find something..

- Joel

Details please, sf.net.
Otherwise the motivation is very probably a completely different one.

As absurd as it can get if an ML admin isn't allowed to see the email
addresses on his/her list.

It seems sf.net wants to be abandoned in general ....

Just create the new - better - list/s and send subscription
information!

I checked, migrating is not an option.
sourceforge has hacked mailman to hide member mail addresses:
"As a result of the latest electronic messaging and privacy requirements 
around the world, SourceForge has implemented a number of changes that affect 
email privacy. One part of this is that it is no longer possible for project 
admins to view the member emails of their mailing lists."

So, I'll ask for a mailinglist on infradead.org.

Thanks,

P.s: Just realized that most of my mails also didn't make it to the 
mailinglist. That _sucks_.

Yes, or infradead.org.
The bigger problem is migrating all users.

Maybe there is a way to extract a list of subscribers from 
lists.sourceforge.net. Jeff made me project admin some time ago, maybe I can 
exhume that account.

Or we are rude and expect everyone to re-subscribe to the new UML list.
That way we might lose 99% of all subscribers but at least the 1% is 
interested in UML for sure. ;-)

You can ask DaveM to create a list at vger.
