  4. fd96e73 While the synchronization in the sched_football testcase under the realtime test suite is not erroneous, it can be enahnced and made more reliable by making use of pthread_barriers, like in other testcases. This patch adds the same. Testing done: Infinite iterations of the testcase run with this patch. by subrata_modak · 16 years ago
  5. 573e348 This is a patch from John, written a few months back. I have fixed up a few cosmetic whitespace bits, and have refreshed it so it should apply cleanly to LTP today. Will Schmidt <will_schmidt@vnet.ibm.com>. by subrata_modak · 16 years ago
  6. 3358671 In tsc_minus, changed test (tsc_begin < tsc_end) by (tsc_begin <= tsc_end) since values can be equal as read operations are sometimes very close.

  7. 49309b9 This macro reads atomically the 64-bit TSC register. Reading the 64-bit register using two 32-bit instructions sometimes causes wrapping when a clock update appears in between. A single 64-bit read fixes this. Signed-off-by: Gilles Carry <gilles.carry@bull.net>. Cc: Tim Chavez <tinytim@us.ibm.com>. by subrata_modak · 16 years ago
  8. 75d0486 First patch regroups TSC functions and macros definition into librttest. Second patch is to have an atomic reading of the 64-bit timebase register of powerpc64. This new function is only valid if -m64 is used when compiling the whole testcase suite with a powerpc64. Thirs patch is a fix to avoid spurious tsc_minus warning. These patches been tested on a ppc64 machine either with 32 or 64 bit binaries. (-m64). by subrata_modak · 16 years ago
  9. b6438db When compiling powerpc binaries, gcc defaults to 32 bit. To do some tests I needed to have a 64 bit binary. Since I'm using realtime, I modified config.mk as below. My questions: is there any official way to turn LTP in 64bit? If not, what shall we do then? Should LTP default to 32 or native-arch bit? Shall we use something like: "if (uname -m) ..." or use a command line option? Any comment? by subrata_modak · 16 years ago

  11. 2c82e33 It looks like the only thing that didn't apply was the function declaration. It builds (with a warning) and runs just fine. But here is a patch to fix the warning. Signed-off-by: Vernon Mauery <vernux@us.ibm.com>. by subrata_modak · 16 years ago
  12. 021ed25 I spent some time looking at the sched_latency test trying to see why it took so long to start the thread. The java version of the test takes a comparable amount of time to start the thread as it does for each period. The rt-test version was taking an order of magnitude longer. After digging through the java documentation, I found that the RealtimeThread does not actually start executing until the RealtimeThread.waitForNextPeriod() fulfills the time specified in the PeriodicParameters parameter included in its constructor. So all the tests are scheduled to run about 1 second after the threads are created. This gives the system plenty of time to create the thread (a non-realtime code path), set the scheduling parameters and then sleep until the specified run time. The start latency as measured by the test goes something like this: by subrata_modak · 16 years ago

  16. 3bfea97 These patches will allow for the plotting of the max over time in discrete segments, rather than as a monotonically increasing value, while maintaining the original behavior by default. The existing test has an infinite window and report the new max each time it is increased. The patch maintains the default behavior and adds a -w option, allowing the user to specify a window (iteration count) for which the max of that window is reported ever w iterations.

  29. 6e619ee I believe we had written this test to debug the other test with a lower overhead clocksource. Unfortunately, the tsc is x86 specific, isn't consistent across CPUs on certain systems, and can have it's frequency changed depending on by power states. For all those reasons this test can simply be removed from the LTP.

  39. fb02e2a Fixes a minor issue with pi_perf testcase (testcases/realtime/func/). The wait_dat is intended to measure the amount of time it took for the high priority thread to actually obtain the lock from the time it was released by the low priority thread. The patch fixes this computation to measure it more accurately. The PASS/FAIL computation is unaffected.

  40. 26b2c9a This patch updates the matrix_mult testcase to closely follow the JVM in the concurrent case.

  41. 30b7df2 Usually the cross compiler is set from the toplevel directory by setting the CROSS_COMPILER variable. This makefile tries to overwrite it, but wrong. It is also possible to push in CFLAGS from the toplevel by using CROSS_CFLAGS. We should use these here as well. Finally, LDFLAGS are set here but not used by the makefiles.

  48. 1db2f5c We have seen that prio_preempt testcase that is part of realtime tests occasionally hangs. This can be easily recreated on a 8-cpu system, but can be recreated on a 4-cpu system as well when run for a number of iterations. The problem occurs because the first worker thread sometimes fails to call cond_wait on the condvar through which the master thread signals it to start. Since the first thread needs to start the chain of signalling from then on, all other threads just sit in a cond_wait without ever being woken up. The fix is to have a barrier to ensure that the first worker thread doesn't miss the cond_signal. I have tested this patch by running 10s of thousands of iterations of the testcase. Without the patch I can recreate the problem fairly easily, by, Sripathi Kodi <sripathik@in.ibm.com> by subrata_modak · 17 years ago
  49. 8349b3f In a lot of cases, we do not really care about the samples and histogram files and their associated gnuplot command files or do not want to save them for example on embedded platforms with limited or no storage.
