LTTng sched_switch documentation patch

2019-08-30 Thread Ravindra Kumar Meena

Hello Chris and Sebastian,

I have attached the updated LTTng sched_switch documentation patch(v5).
This one is a whole single patch.

Please review the attached patch.

*What changed from v4 to v5:*
* rtems-record-lttng tool is now available via RSB. So for the same, I have
updated the patch.
* I have removed the Trace Compass screen capture.
* I have REST numbering format.
* Removed the telent command. Telnet is not required for tracing.
* set the code block type to shell.
* Added few lines for raw-data.

Thanks

[PATCH] record: Allow tracing of ISR disable/enable

2019-08-30 Thread Sebastian Huber

Directly use the CPU port API in boot_card() to allow tracing of the
higher level interrupt disable/enable routines, e.g.
_ISR_Local_disable() and _ISR_Local_enable().  Currently, there is no
configuration option to enable this.  Below is a patch.  It may be used
to investigate some nasty low level bugs in the system.

Update #3665.

Test cases should use assertions to check test conditions.  The new test 
framework helps you to do this:


https://docs.rtems.org/branches/master/eng/test-framework.html#posix-error-numbers

https://docs.rtems.org/branches/master/eng/test-framework.html#posix-status-codes

You should also test for success and not some failure.

It's no more needed, I'll post a patch to remove it.
Also, I'll post patches to add a README and README.waf for the repo.

... because you should order the definitions properly.  Only if two static 
functions need to reference each other do you need to forward declare one.  
That’s a rare situation.

[PATCH] record: Add wrappers for malloc() functions

2019-08-30 Thread Sebastian Huber

Introduce new library librtemsrecordwrap.a which contains wrappers for
operating system functions which produce entry/exit events.

The wrappers can be selected during link time via the GNU ld --wrap
option.

Update #3665.

Convert rtems-record-lttng program to C++

2019-08-30 Thread Sebastian Huber

Hello,

attached are two patches which convert the rtems-record-lttng client program 
from C to C++. I used

clang-format -style=Chromium -i trace/record/record-main-lttng.cc

to format the source.
