Re: [rtl] RTL V3 - how to

["Stuart Warren" <SWarren@btr-auto.aust.com>]

Hi Nathan,

I've tried out pre6e and found that the rtlsigtimer_app in the
regression directory will crash my computer when calling
rtlinux_sigprocmask.  When these calls are removed, the test will work. 
It looks like there a minor problem with the logic for testing the
results.  I changed it to:


/* check that the timers went off the right number of times */
if ((*marker_ptr != 8) || (*marker2_ptr != 16))
{
	....
}

(ditto for the single periodic timer test)

The results showed that each periodic task would run just once
(*marker2_ptr was 1).

I found the same with a test program I was using.  It worked okay under
pre6d.

Any ideas?  Need more info?

cheers,
stuart warren

This is some code that runs correctly under pre6d but only increments to
1 under pre6e... (ie the same behaviour as the modified regression
program)
