Re: [Xenomai-core] NIOS2/Xenomai 2.5.6/Native Skin

2011-04-14 Thread Patrice Kadionik
 'timer' device.

I am planing
 * to deviate the Linux timer interrupt from our 'timer' source, by
   using a virtual IRQ line, to
   a) phase align it to other events in the schedule
   b) make the timer available to Xenomai, and
 * to implement a read-tsc function and use a spare timer for Xenomai.

My Questions:
 * Are there any implications to Xenomai-services, aside from timed 
events
   (i.e. sleep, alarms, timeout functions, ...) which need to be 
regarded when

   working on the time source?
 * Is there any hardware dependent code in Xenomai that relies on the 
current
   timer (hrclock, hrtimer) implementation? I.e. can all modifications 
inside

   the ADEOS code?
   I have only identified only ADEOS code so far.
Yes, I think that all the hardware dependent code is in the adeos patch. 
In the adeos patch for NIOS 2 without MMU, you must instantiate with 
Altera SoPC builder tool a 32-bit timer named hrtimer for clock event 
and a 64-bit timer named hrclock for clock source. Link between HW and 
SW is done by the name.


Cheers;

Patrice


thx  best regards
Martin



PS: This discussion should rather happen on xenomai-help or -core, at
your will. Maybe those explanations could be of some interest to others.


Best regards
Martin Elshuber

Re: [Xenomai-core] Build tests: analogy, blackfin, rtcan and nios2.

Hi Gilles,

Gilles Chanteperdrix a écrit :
 Hi,

 Since I started talking about it, I have run build tests fixing a few
 things here and there. The current status is this (still at the same
 place: http://sisyphus.hd.free.fr/~gilles/bx):

 * analogy: I have tried to disable some parts of analogy when compiling
 on machines without CONFIG_PCI, as compiling parts using PCI on a
 machine without PCI support, give various levels of warning and even
 errors depending on the architecture. Doing this, I stumbled across this
 compilation error:
 http://sisyphus.hd.free.fr/~gilles/bx/beagle/2.6.28-arm-none-linux-gnueabi-gcc-4.3.3/log.html#1
 this is with CONFIG_NI_MIO, but without CONFIG_NI_MITE.

 So, Alex, could you:
 - fix that error, if this combination is supposed to make sense
 - fix the Kconfig/Makefile so that no PCI code is compiled if CONFIG_PCI
 is not set (I tried and do this myself, but better one who knows than
 100 who have to search...). As I said, doing this result in various
 levels of success depending on the architecture.

 * blackfin: I finally compiled blackfin! had to build a toolchain for
 that as the binary-only toolchain from analog.com uses glibc 2.8 and
 mine is 2.7. However, blackfin does not compile very well, as can be
 seen by the log:
 http://sisyphus.hd.free.fr/~gilles/bx/bf537-stamp/2.6.30-bfin-uclinux-gcc-4.1.2/log.html#1
 It may happen that my toolchain is buggy or outdated though.

 * rtcan: on blackfin we seem to have a conflict with rtcan.
 The warning is about CAN_ERR_MASK, sure blackfin is a bit strange to
 define this in core headers which are included everywhere. This said,
 not prefixing a Xenomai symbol with something like XN seems to be asking
 for trouble. Wolfgang, do you think it would be possible to rename the
 symbols with such prefix? Or do you share some code with socket-can that
 you do not want to touch?

 * nios2: I am lacking some important file needed to even start to compile.

   
You may use this tutorial on how to use Xenomai on NIOS 2 softcore 
processor:

 Thanks in advance for your efforts.

Hi,

I've watched your log file for nios2 
(http://sisyphus.hd.free.fr/~gilles/bx/nios2/2.6.30-nios2-linux-uclibc-gcc-3.4.6/log.html#1). 
You have this error because you don't have generated before the HW 
design for the NIOS softcore processor: after synthesis with the Quartus 
Altera tools, you finally have a file for programming the FPGA circuit 
and a .ptf file that gives ASCII informations on your SoPC design (in a 
xml style...).

The error:
./arch/nios2/Makefile:131: *** Run make hwselect SYSPTF=system.ptf 
first. Stop.

is due to lack of this .ptf file.
This command generates a .h (nios2.h) file that makes relation between 
hardware and the Linux kernel (peripheral base address, irq number, 
peripheral name...)

Please find here: http://uuu.enseirb.fr/~kadionik/nios-xenomai/std_1s10.ptf
a valid .ptf file for Xenomai port.
Juste run :
$ make hwselect SYSPTF=path_to_std_1s10.ptf
for completing the kernel compilation...

Pat.
