[Xenomai-core] Wrong example code in Native-API-Tour

[Xenomai-core] Wrong example code in Native-API-Tour

[Sebastian Smolorz]

Hello Philippe,

on page 21 of Native-API-Tour-rev-C.pdf one gets the impression that 
rt_intr_wait() returns 0 on success. However, it returns a positive value in 
this case (as the API description states it right).

[Xenomai-core] Xenomai on MIPS MALTA

[somshekar kadam]

Hi Phillep,

 good news xenomai porting for mips is done, user
space application are working fine. once the formality
with our client gets over we will submit the code to
open source. People contirbuted for this project are
Subramani,Manoj,Sanjeev,Nishit,Poornima and Neelu. 

Right now debugging an issue for kernel space module
where rt task start goes for toss, will be fixed next
week probably, subramni will be working on it. 

we hope to deliver it for MIPS MALTA BOARD, as we need
to get it working for Malta borad, after we release to
our customer. 
we will need help in fixing performance issues from
open source community. 

Thanks for everybody helping us in this project

Thanks And regards
Neelu

The sooner you are able to release, the sooner the community can help...

[Xenomai-core] Xenomai module poblem

[somshekar kadam]

Hi All, 

  I have already posted to the maling list regarding
the Xenomai and ADEOS release for MIPS. Now we are in
a stage where all User RT Applications are working
fine. 
Unless we give complete port to the customer we wont
be able to release to open source the work done. I
know this is not liked by anyone, our team needs to
leave with it. 
 May 12 is the date to where we think of giving the
final release. 
now we are left with only one problem the xenomai
module doesnt work for us, it fails in start_thread
for module. same context switch will be used for
xenomai module also, right now no idea on this may be
some pointer will help us speedup the release and
contribute to opensource. we have done latency test we
are getting 19Us for interrupt latency 33 us for
context switch latency and normal latekcy is 77us. 
I came across Dmitry Adamushko doing the same work,
may if any pointers you have will help us. 

Thanks In advance 
Neelu

Hi,

That was my intention and I started to implement some bits.. but
shortly after that you announced an "alsmost-completed" port (as I
recall it was estimated to be released somewhere in April) so I
decided not to duplicate efforts (as it was just for fun, not any
need-for-work necessity) but rather help with reviewing and
straightening of the code once it gets released.

sorry, but this looks like a mess and one should guess really hard to
extract some relevant bits (if any).

start_thread() == xnpod_start_thread? for module? what kind of
"context switch" term can used for module (== kernel module)? and you
claim that "all User RT Applications are working fine" and "the
xenomai module doesnt work for us".

I think noone is able to help you unless (1) you do release code
publicly or (2) you are really very specific (technically-wise)
describing your problem. (2) is not that easy as it would require
looking at other parts of the code and we are, well, kind of "blind"
here.

[somshekar kadam]

Hi All, 


Good News , now we are able to run User Space
Applications as well as Kernel Module, Implemented the
the thread related part xnarch_thread_init, basically
intialize the stack frame for thread to do context
switch, now able to go to rthal_thread_trampoline and
next to xnarch_thread_trampoline and able to switch to
new thread and able to execute, once the xenomai we
check for proper stability and performance for client
, we will release ADEOS and XENOMAI for MIPS core for
OPEN SOURCE. We thank Open community for all the help
especially Philip, Jan ,Dimitry and Gallies, once
again thanks a lot for all the help without your
contirbiution it would be successful. 

may be next we have discussion with client and once
client accepts it we release the code. 

Thanks And Regards
Neelu
