Linux RT patch works on single core - but not booting SMP ARM OMAP4 PandaBoard

Hello everyone,

First of all, thanks to everyone for the RT patch and it is awesome
work. I got stable 3.0.1 + 3.0.1-rt8 patch single-core kernel working
on a PandaBoard (with another patch for getting the high resolution
timer to work on PandaBoard). With cyclictest, I am seeing a maximum
latency of ~25 us (~36 us with some ethernet traffic). The test
results are really really promising and kudos to tglx, et al. I am
also planning to run the tests for a longer period of time.

However, with the RT patch applied, I cannot get the SMP kernel to
boot [Note: stable 3.0.1 SMP kernel boots just fine without RT patch].
I have tried with and without the other high-resolution timer patch.
It hangs the same way very early with the following message:
*************
reading uImage

2828444 bytes read
Booting from mmc0 ...
## Booting kernel from Legacy Image at 82000000 ...
   Image Name:   Linux-3.0.1-rt8+
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    2828380 Bytes = 2.7 MiB
   Load Address: 80008000
   Entry Point:  80008000
   Verifying Checksum ... OK
   Loading Kernel Image ... OK
OK

Starting kernel ...

Uncompressing Linux... done, booting the kernel.
*************

I have attached 4 kernel config files - 2 booting fine and 2 not
booting (Legend for interpreting file names: sc = single core, rt =
rt-patch, hrt = high-resolution-timer-patch)

Note: I have tried even earlier version of the RT patches and all of
them fail. However, I vaguely recall the first or second RT patch that
was released booted SMP fine but I cannot make it work again now.

Has anyone been successful in booting SMP on panda board or other
OMAP4/ARM targets with RT patch?

Is there anything wrong with my config files for SMP with RT patch on ARM?

Any suggestions to debug early hangs on panda board with RT patch ?

Thanks in advance,
Sankara Muthukrishnan

SMP Panda is booting fine for me on a slightly older version: 3.0.0-rt6

gcc 4.3.3

Config is attached.

I used make omap2plus_defconfig then tweaked a few items:

# this allows USB thumb drive
# Device Drivers -> USB support -> EHCI HCD (USB 2.0) support
CONFIG_USB_EHCI_HCD=y
# Device Drivers -> USB support -> EHCI support for OMAP3 and later chips
CONFIG_USB_EHCI_HCD_OMAP=y

# ethernet device
# Device Drivers -> Network device support -> USB Network Adapters ->
#  Multi-purpose USB Networking Framework ->
#  SMSC LAN95XX based USB 2.0 10/100 ethernet devices
CONFIG_USB_NET_SMSC95XX=y

# Kernel Features -> Preemption Model -> Fully Preemptible Kernel (RT)

And 3.0.1-rt11 also boots SMP CONFIG_PREEMPT_RT_FULL on panda board for
me, with the same recipe I gave for 3.0.0-rt6.

Thanks Frank. I first tried your suggestion of "make
omap2plus_defconfig" with additional config options to enable USB
ethernet with rt8 patch but could not get SMP kernel to boot. Then, I
applied rt11 patch and used the exact same .config file that you had
posted in this thread and the SMP kernel is booting fine now. I have
applied the following high-resolution timer patch that is posted in
the OMAP mailing list:

************ PATCH END **************
The cyclic test results are not acceptable (attached the output of
cyclictest). I am seeing maximum latency of 757 us on core-0 and 1905
us on core-1. Are you (Is anyone) seeing better results on latency
with SMP kernel with RT patch on ARM (OMAP4 processors)? I have seen
~25 us of latency with single core kernel (though I have used a
different kernel configuration).

PS: The kernels that I build especially with RT patch don't boot the
first time on the panda board. Sometimes, it takes 2 or 3 resets and
sometimes 10 to 15 times. When it hangs, it always hangs right after
"Uncompressing Linux... done, booting the kernel." It looks like it is
probably due to some race conditions in kernel during initial boot. I
am hoping it is not a hardware issue. Has anyone else been
experiencing flakiness and early hangs on panda board? I am using code
sourcery toolchain (Sourcery G++ Lite 2010.09-50 for ARM GNU/Linux )
to build the kernel. The Linux kernels at some point in the past month
or so that I built with the latest code sourcery toolchain (Sourcery
G++ Lite 2011.03-41 for ARM GNU/Linux) did not boot. That said, it is
hard to blame the toolchain, because of the flakiness in booting the
same kernel image (boots fine after 15 resets).

Thanks,
Sankara Muthukrishnan

Never ever mind and sorry for the confusion. I did not realize that
"Kernel debugging" was enabled in the config Frank had attached. With
kernel debugging disabled, I see max latencies less than 20 us on both
cores on panda board with cyclictest (cyclictest -l1000000 -m -Sp99
-i200 -h60 -q -n) in my quick run and it is exciting to see these
numbers. Thanks Frank.

If i use the omap2plus_defconfig of the 3.0.1 kernel i can't get a bootable 
kernel with RT full preemption.

If i apply the Frank config to the 3.0.1 source tree with RT-patch i get a 
working kernel with full preemption and SMP.

Unless i'm very much mistaken the defconfig of the 3.0.0 which Frank config come 
from is a little bit different from the 3.0.1 version and it gives some 
problems when the RT-patch is applied.

I tried to perform a cyclictest too but i get a segmentation fault when the 
test is executing with SMP testing option enabled.
Did anyone get the same problem?

Can you send me the config file that gives you a non-bootable kernel?

You didn't mention whether you are getting any console messages when
the boot hangs.  If you aren't getting any messages, then the attached
patches __might__ allow some messages to get out.  You also need to
enable CONFIG_DEBUG_LL and CONFIG_EARLY_PRINTK, and also add
earlyprintk to the kernel boot command line.

(I need to clean up the patches a bit before even thinking about
whether they should be submitted.)

WARNING: this is a hack to support debugging.


For CONFIG_PREEMPT_RT_FULL console_trylock_for_printk() will not attempt to
lock the console if:
   !early_boot_irqs_disabled && !irqs_disabled_flags(flags) && !preempt_count()
thus vprintk() will not print out the buffers.

Allow console_trylock_for_printk() attempt to lock the console if
sysrq_in_progress.

This hack patch sets oops_in_progress so that sysrq output can maybe get
delivered to the console without delay.


Using oops_in_progress is important because that also affects the locking
methods used by the serial driver.

I just sent a couple of patches in reply to "[ANNOUNCE] 3.0.1-rt11".  They
might help resolve your panda board hang on boot.

I haven't done any performance testing yet.

The panda has been booting consistently for me.

But I'm having problems getting SMP to boot on other ARM boards (a
silent fail, like your panda).  My realview SMP fails with plain
3.0.0 (I have not tried with the RT patches added).  I ported support
for the NaviEngine (out of tree, yuchh) forward, and am debugging
SMP boot failure on that now.  I don't know if the problem is due
to my quick and dirty porting method, or something else.
