[LTP] 答复: [PATCH] Reduce loop count to meet need of low performance terminals

[徐飞飞(Steve)]

Are you sure that your kernel isn't affected by the bug the test checks for? The test timeouts on a buggy kernel.
-- Is there any place where I can see more relevant information? which kind of bug you have found?

the test timeout on myside where there still 640000 loop,
ZZL pid = 29466 this is while 646533 times loop = 646533 -------
ZZL pid = 29466 this is while 646532 times loop = 646532 -------
ZZL pid = 29466 this is while 646531 times loop = 646531 -------
ZZL pid = 29466 this is while 646530 times loop = 646530 -------
ZZL pid = 29466 this is while 646529 times loop = 646529 -------
ZZL pid = 29466 this is while 646528 times loop = 646528 -------
ZZL pid = 29466 this is while 646527 times loop = 646527 -------
ZZL pid = 29466 this is while 646526 times loop = 646526 -------
ZZL pid = 29466 this is while 646525 times loop = 646525 -------
ZZL pid = 29466 this is while 646524 times loop = 646524 -------
ZZL pid = 29466 this is while 646523 times loop = 646523 -------
ZZL pid = 29466 this is while 646522 times loop = 646522 -------
ZZL pid = 29466 this is while 646521 times loop = 646521 -------
Test timeouted, sending SIGKILL!
external/ltp/lib/tst_test.c:1641: TINFO: Killed the leftover descendant processes
external/ltp/lib/tst_test.c:1648: TINFO: If you are running on slow machine, try exporting LTP_TIMEOUT_MUL > 1
external/ltp/lib/tst_test.c:1649: TBROK: Test killed! (timeout?)

Summary:
passed   1
failed   0
broken   1
skipped  0
warnings 0


How long does the test run if you disable timeouts (by setting static int timeout = -1 in the source)?
-- about 370 seconds

Also what kind of system it is? How fast is the CPU?
