Description IBM Bug Proxy 2008-09-30 17:02:04 EDT
The version of rtcheck in MRG has a number of issues which have resolved in this
latest version (attached below).  They include:

Updates include:
o whitespace cleanups
o reimplemented output macros (greatly reduced code size)
o removal of hrtimer loop (runs much faster now)
o use clock_gettime(CLOCK_MONOTONIC,...) instead of gtod()
o use clock_nanosleep() instead of nanosleep()
o sleep for measurable period of time (50us) rather than 1ns (which is a no-op
system call basically)
o verbose flag always prints reported values (not just on fail)
o verbose flag always reruns tests (ignores cache)
o new -p priority option
o test is run by default as SCHED_FIFO 95 (rather than SCHED_OTHER)
o test is run with mlockall(CURRENT|FUTURE) to avoid paging induced latencies
o cleaned up output formatting for verbose flag (more intuitive messages)

rtcheck.c version 7-4 (updated)

Updated version of rtcheck.c with ns aware clock resolution reporting.

Comment 2 Clark Williams 2008-10-21 14:09:34 EDT
can I get a CHANGELOG updated for 0.7.4? Better yet, do you have a tarball with all the things needed (Makefile, rtcheck.c, CHANGELOG, INSTALL, README, TODO)?
Comment 3 Clark Williams 2008-10-23 14:09:31 EDT
build rtcheck-0.7.4-2 from tarball supplied by IBM

Scheduled to deliver in MRG 1.1

Updated rtcheck with a changelog and init script

Please update to this latest version of rtcheck (0.7.5) which includes a full
CHANGELOG and a proper init script.  I have tested it on MRG-GA.
