Hi list,

I'm very interested in running RT Linux on my Arietta boad: the question
has been raised on the acmesystems forum
(https://groups.google.com/forum/#!topic/acmesystems/_AyrGYMXBmc), so
I'm not alone!

I have tried 4.4.2-rt7. When configuring PREEMPT__LL, my config works
fine, but when just changing to PREEMPT_RT_FULL, it won't boot.

This is what I get with PREEMPT__LL :
---------------------------------------------
Booting zImage ......

Linux arietta 4.4.2-rt7 #1 PREEMPT Sat Feb 27 09:39:38 TAHT 2016
armv5tejl GNU/Linux
---------------------------------------------

With PREEMPT_RT_FULL, nothing happens after "Starting linux kernel ...,
machid: 0xffffffff".

I'm a newbie on Linux RT, so maybe something is wrong in my config (see
attached file): any help would be appreciated.


Thanks,

Alexandre Belloni wrote something about rt and at91 that might be worth
to look into. I don't know how much of it is obsolete with 4.4.2-rt7,
though.

I have read (and replied to) that article, and even tried to apply some
of the patches mentioned, but could never get kernel to boot.

As I said, I'm a newbie on Linux RT: is there anything I should check in
my kernel config? I mean, are there any configuration parameters none to
be a problem with PREEMPT_RT_FULL, but working fine with PREEMPT__LL?


Thanks,

I think your best bet will be to try to get early console output, with
the hope that you can get visibility into what is going wrong.  I'm sure
there are many tutorials out there on how to build a kernel with this
serial debugging information.  Do a search for DEBUG_LL, earlyprintk,
and perhaps earlycon; these are not -rt specific.

Thanks for your advice. I managed to configure earlyprintk, this is what

This confirms that the problem you are seeing is the same problem
Alexandre and Boris solved in:

   https://www.spinics.net/lists/kernel/msg2172523.html

It doesn't look like it's landed upstream yet (although it's been in
next since last week).

It looks like Alexandre has pushed a tag with these changes (destined
for 4.6) at:

  git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux.git at91-ab-4.6-drivers

You can cherry-pick back those top 13 commits and give it a try.

If you can confirm that those changes fix your problem, they should be
considered for cherry-picking into 4.4-rt officially.

I also have that branch for preempt-rt on at91:

https://github.com/alexandrebelloni/linux/tree/at91-rt

I'll make sure my changes will land in the next -rt releases but I had
to make sure which version will land in the mainline first.

Hi,

I've not been able to apply the 13 patches on 4.4.3-rt9 due to
conflicts, and then kernel would not compile.

So I tried your at91-rt branch, Alexandre, and I'm pleased to report
that it works!

I'm just getting this warning:

at91_i2c f8014000.i2c: using dma1chan0 (tx) and dma1chan1 (rx) for DMA
transfers

But the arietta seems to run fine. I'm getting about 100 - 250 µs
latencies on a simple GPIO test.

Yeah. You can't use CLK framework in atomic context on -RT [1], [2].

The AT91 problems are mostly gone in v4.4.4-rt11. There is one last
free_irq() related warning which will be gone in v4.4.6-rt13.
