Xenomai for A13 - A10

[crubille]

Hello,

so if i get a running kernel, i dont still have xenomai application working - and i dont know why.

If you suspect me to dont send infos, i remember you i send infos about patchs and A10 timers, but last week i cant do anything and have no mail.

If you wand, send me your mail adress in private messages and i send you back the files in a more convenient forms.

Saturday, i start write some code and let it compile (on the A13) sunday in the night.
Monday, i get a kernel which hang the A13.
In the evening i check it and recompile.
This morning i get a kernel, boot the A13 and go to my office.

So, it is for the sunxi 3.4 kernel.
The xenomai ipipe-core-3.4.6-arm-4.patch fail in some place but it is obvious to correct the faillures.
I then have to
- add one line in arch/arm/Kconfig for the sun5i as for several others arm:

Code Select Expand


       select IPIPE_ARM_KUSER_TSC if IPIPE


- add definition for TIMER2 and TIMER4 in arch/arm/plat-sunxi/include/plat/platform.h

Code Select Expand



#ifdef CONFIG_IPIPE
#define SW_TIMER2_CTL_REG                 (SW_VA_TIMERC_IO_BASE + 0x30)

#define SW_TIMER4_CNTVAL_REG              (SW_VA_TIMERC_IO_BASE + 0x58)
#endif /* CONFIG_IPIPE */

So you have to change TMR1 -> TMR2, we have nothing to do with TMR1.
And the maximum clock source is 200MHz because PLL6/6 can be the highest clock source for timer2.
You have to change TIMER2_HPET_CLOCK_EVENT_HZ to 200MHz and have to recalculate min/max deltas. It will be 200MHz instead of 300MHz, its still fine, not so few, dont let it bring you down.
Tell me if Im wrong, Im a slow learner, I wont get offended.

- Nice catch on the PLL6/6, When I read the datasheet for the processor I saw the big notice that PLL6 outputs 1.2GHz and nothing else and I wrote off the div6 defore it even hit the TMR_2_CLK_PRESCALE.

- The Tim1's where a copy-paste mistake but they where fixed on my second kernel.

- I will re-calculate the values based on 200MHz clock but it shouldn't change much as I think the kernel was hanging due to a to-often ISR or pushing wrong TSC to the processor. I will go through crubille's change and see if were on the same track.

Crubille:

   I notice you are using a different convention for inserting the timer into the system and registering it with the I-Pipe. Where did you find documentation to do it your way? When I compiled my 3.0.x and 3.4.x kernels they demanded the following functions to work:

Code Select Expand


int __ipipe_mach_ticks_per_jiffy
int __ipipe_mach_timerstolen
int __ipipe_mach_timerint
__ipipe_mach_get_tsc(void)
__ipipe_mach_get_dec(void)
__ipipe_mach_release_timer(void)
__ipipe_mach_set_dec(unsigned long delay)
__ipipe_mach_acktimer(void)


That was with Xenomai-2.6.2.1 patched into the kernel.

[crubille]

At this time, i use the 24 Mhz clock for the clock (TIMER 2) and the clocktest show it is ok
and for the timer (TIMER4) and nothing append.

It is not a problem to swith the clock to PLL6/6, just check ticks are coherents.

At this time, my main question is: is the IRQ for TIMER4 really 67 ?

Latest & Greatest Kernal

EDIT:
Can you give this one a try too:
3.4.24-r1-xeno-debug
I have been working on getting the 3.4.x patched and some latest merges have made it possible. If this one works then were quite a few steps ahead.

Latest and greatest kernel boot log:
http://pastebin.com/2TPFtwqL

3.4.24-r1 kernel boot log:
http://pastebin.com/qQBn9LJY

[uMinded]

3.4.24-r1 kernel boot log:
http://pastebin.com/qQBn9LJY

Now that's some real kernel debug messages eh! The I-Pipe TSC/cpu sync is the main problem with 3.0.36 so I am going to dump that kernel in favor of 3.4.24 as that actually boots with Xenomai.

I'm going to take a shot at doing it the way crubille did and see if we can get it booted and loaded.

crubille:

  I would be careful of the 3.4.24 version of arch/arm/plat-sunxi/include/plat/platform.h as some of the virtual address pointers are offset by 0x10 and you could reset a system clock unintentionally or worse. See the linux-sunxi.org site for the register definitions.

[uMinded]

This should boot up now:
Linux-3.4.24-r1-xeno-debug-r1-xe
Xenomai-2.6.2.1 User Progs

Hopefully the user programs work, I compiled them for -march=armv7-a -mfpu=vfp3

If it does can you please run the following:

Code Select Expand


/usr/xenomai/bin/clocktest -C sun5i_timer2  // Or just clocktest to test them all
/usr/xenomai/bin/latency


As usual dump them all please.

I talked to DigiKey, they didn't want to test my board and said they would call back. They have not so I will call them tomorrow and see if they can do it and ship ASAP.

This should boot up now:
Linux-3.4.24-r1-xeno-debug-r1-xe

Xenomai services has been started. But then later it freezes at sw-ehci. Hmmmm.

[uMinded]

Hmm that is quite strange... I did not go anywhere near that subsystem.

Similar Bootlog

You can see in that if you search for "sw-ehci1" that that IRQ and memory address is indeed correct so why it would freeze I have no idea.

crubille:

  Did you have any USB issues when it comes to booting? Can you post your 3.4.x config file?

[Tele]

Hmm that is quite strange...

Have to do it methodically. First we should compile a vanilla sunxi-3.2.24-r1 kernel with an A13_defconfig. If it runs then we can patch it with adeos-ipipe and high-res timer.

By the way, I have some doubts about this 3.2.24 kernel way. Because adeos ipipe patch was made for 3.2.21 kernel not for 3.2.24. If the patch runs without error (after modification) that is nice but it does not necessarily follow that is enough for the correct kernel patch. If you wanna be precise you have to compare 3.2.24 and 3.2.21 vanilla kernels, and then sunxi kernels in the aspect of ipipe patches. Otherwise you take some risk, you enter a twilight zone.

Im gonna try a vanilla sunxi-3.2.24-r1, then I come back to report.

EDIT:
I cant test that because it does not exist.
Maybe sunxi-3.4.24 patched with adeos ipipe 3.4.6
Hmmm.
EDIT2:
I cant do it for now. Sunxi gihub returns a server error 500. uMinded could you upload an unmodified sunxi-3.4.24-r1 onto your github please.

I agree, I will upload a vanilla kernel with just a defconfig.

The I-Pipe patch really is not that much of a modification, I would say over half if it is just putting spinlocks in the appropriate places. And revisions between the minor version are exactly that, minor. CHANGELOGS Just put in the kernel version in the web address to bring up the commit log and 80% are bugfixes for specific hardware, 10% code tweeks (like a line or two), 10% are actual compile/module tweeks.

Kernel development has seriously accelerated in the past 5 years, I remember back when I was working on 2.6.x and now were on 3.8.x!

I cant test that because it does not exist.
Maybe sunxi-3.4.24 patched with adeos ipipe 3.4.6
Hmmm.

I just started using github last week, I am having huge problems pushing to remotes as I use two different computers for development and my branch pointers are not being stored properly, checkouts do not pull changes, etc. Finding a branch in the linux-sunxi kernel is painful at best as "git branch -a" only lists the ones one off master. the 3.4.24-r1 is in a remote node.

Code Select Expand


git clone git://github.com/linux-sunxi/linux-sunxi.git
git checkout sunxi-v3.4.24-r1

// If you do the following:

git log --all | grep "2.4."

// You will get a listing of the current working branches. Anything with a -rn appended seems to have full sunxi patches.


[ehj666]

Xenomai services has been started. But then later it freezes at sw-ehci. Hmmmm.

Yep. Just confirming, I get the same thing.

[Tele]

The I-Pipe patch really is not that much....

Its ok, I believe you. I was just thinking loudly. But Im a noobcake anyway, and thats a fact.

I hate 'git checkout'. It downloads about 1GB datas, althought sunxi-v3.4.24.r1.tar.gz is about 140MB. 'git checkout' is a peas of crab, but ok I will use it, if must.

Where the heck did you find sunxi-v3.4.24.r1.tar.gz?? I have not found a way to download the isolated commits and 3.4.24-r1 is not listed as a tracked branch.

Yes it does download about 1GB even though the kernel source is <300mb but thats because the 2.4.24-r1 is about 16 branches deep and a couple hundred thousand commits. I'm sure theirs a way to just checkout the thread of commits for your requested checkout but I am new to Git as well...


Here is a13-olinuxino_defconfig + the boot string:
Linux-3.4.24-r1-vanilla

[Tele]

Where the heck did you find sunxi-v3.4.24.r1.tar.gz?? ...

Yes you can download gzipped tarballs as well.
https://github.com/linux-sunxi/linux-sunxi/tags

You will find a huge list (611) of tagged files. At the beginning and middle of the list you can see vanilla unmodified kernels, bases of forks. They look like v3.x.y or v2.x.y...all vanilla kernels, no sunxi stuffs inside. At the end of list(after many 'next page') you will see sunxi-3.x.y files, they are stable sunxi releases. They are about 140MB gzipped tarballs. At this moment it doesnt work, after few 'next page' it shows a server error 500. It worked before, and I used it instead of stupid 'github checkout':
Counting files...
Compressing files...
Getting files...
then you better go to take a lunch break, it wont be a quick one.
I reported this bug to github, I hope they fix it soon.
