NAMEdahdi_test - Test if the DAHDI timer provides timely response
SYNOPSISdahdi_test [ -v ]
DESCRIPTIONdahdi_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.
