dahdi_test — Test if the DAHDI timer provides timely response
Contents
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.
