NAME

dahdi_test --- Test if the DAHDI timer provides timely response  

SYNOPSIS

dahdi_test [ -v ]

 

DESCRIPTION

dahdi_test dahdi_test runs a timing test in a loop and prints the result of each loop. The test is as follows:

It reads 8192 bytes from the DAHDI timer device (/dev/dahdi/pseudo). This should take exactly 8000 ms . It uses calls to gettimeofday(2) before and after that read to check that indeed exactly 8000ms have passed.

Values of 100% and 99.99% Are normally considered a definite pass. Values of 99.98% and 99.97% are probably OK as well.

 

OPTIONS

-v
Be more verbose: print one line per test.

-c count

Run for count times instead of running forever.

 

FILES

/dev/dahdi/pseudo
The device file used to access the DAHDI timer.
