Some details on the missing tests:
-----------------------------------
smpfatal09: This test actually does pass, but because the fatal error handler
is executed before the console is initialized, no output is produced.
smpclock01.exe: Here CPU0 disables its local interrupts and waits for a barrier
release of CPU1. This means it doesn't handle timer interrupts anymore and
doesn't send corresponding IPIs to other CPUs.
At the same time CPU1 is waiting for a timer event before releasing the
barrier. Any hints how to resolve this are very welcome.
This could be a Qemu timing issue.
smpatomic01: This test seems very large and a bit complicated to me. I will
have a look at it next, but any suggestions are welcome. It fails with this
information:
] === atomic or/and test case ===
] worker 0 value: 1
] worker 1 value: 0
] atomic value: expected = 1, actual = 1
]
../../../../../../smp-refex-rtems/c/src/../../testsuites/smptests/smpatomic01/init.c:
404 n - s < LONG_MAX
]
] *** FATAL ***
This looks like a bug in smpatomic01. We need a better test case for
atomic_thread_fence().
smpopenmp01: I don't know more about openmp then what is on wikipedia. It has
currently a low priority for me.
This test should not fail. Could be also a Qemu issue.
