Re: [PATCH] APA definitions

2020-06-19 Thread Richi Dubey 
Hi,
Thanks again for your detailed explanation and review. I've sent in the new
patch with the changes. Also writing 'qa' after visually selecting words by
pressing v did not do anything. I also search the docs on
http://vimdoc.sourceforge.net/htmldoc/editing.html but couldn't find
anything. What is qa supposed to do? Is it related to formatting?

Please let me know.

Thanks,
Richi.

haven't been able to find a multicast setup example for FreeBSD. The 
Linux commands are:

Re: Context switching for protected stacks

You can start with the CPP macro you suggest, but eventually we probably
want to make all of this part of application configuration. It is probably
easier to develop using the macros, and then refactor later.

Re: Multicast in Libbsd

2020-06-19 Thread Heinz Junkes 
I can agree with Cedric.

I use rtems5 with rtems-libbsd. I initialize the network interfaces of my 
target via dhcpcd 
and the interfaces are automatically multicast capable.

This works without creating a route:

 if (setsockopt(conf->udp, IPPROTO_IP, IP_ADD_MEMBERSHIP,
(char *) &mreq, sizeof(mreq))!=0) {
struct sockaddr_in temp;
char name[40];
...

Re: Multicast in Libbsd

2020-06-19 Thread Joel Sherrill 
This turned out to be a trivial problem but hard to figure out. :(

The code has a POSIX_Init which initializes the stack and then calls the
application's main() which spawns a number of threads which start using the
stack. I disabled the POSIX_Init from calling main(), added mcast-listener
and mcast-writer (standard net code I had) as shell programs, and then
telnet'ed into the target. I could telnet in twice and run a listener in
one session and a writer in another. This proved that multicast was working
and made me wonder if there was a race condition on stack initialization
since it takes a little while to login twice and run two programs.

I put a sleep(10) before calling main() and the program came up. Based on
its output, it got through initialization but then faulted. I tracked that
down to RTEMS implementation of posix_devctl() being correct and the
adapter being used on Linux was incorrect.

*** Is there a reliable way to know the stack is settled out before the
application can run?

*** I still have to get the multicast out of qemu but that's another issue.

Thanks for the suggestions everyone.

Okay Chris, thank you for this suggestion, I will work on this and update
you.
I can tell you that I encountered the same error when I was building ptpd
with erc32 using RSB and then I was asked to add a different package that
contains netinet/ip.h and then build it first. I will get to you more on
this error
because I have worked on it earlier however while building it configure
errors
again started playing their tricks and when I started doing it with
xilinx_zynq_a9_qemu using RSB,
 it never came but the errors as mentioned earlier came up.

There is a BSP for the TI tms570 (rtems/bsps/arm/tms570) which should be an
r5 similar to what you are targeting.

I'd like to say yesterday, last week, last month, ... but there is at least
one issue to close before it is final I think.

And there was a report of the Pi2 not working with SMP which is troubling.

Another question is when the 5.1 edition will be released? Thank you very much!
