.SH DESCRIPTION
|
||
|
|
.B 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 (\fI/dev/dahdi/pseudo\fR).
|
||
|
|
This should take exactly 8000 ms . It uses calls to
|
||
|
|
.I 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
|
||
|
|
.I pass.
|
||
|
|
Values of 99.98% and 99.97% are probably OK as well.
