  3. 077a00e Patch to change the format of Steve Rostedt's rt-migrate-test testcase: This patch converts the testcase rt-migrate-test.c to the coding format used by the other realtime testcases in LTP, by making use of the librttest and libstats infrastructure.

  4. 2d876b0 prio-wake: Enable using more than 95 threads: prio-wake will currently spew pthread errors on systems with more than 95 CPUS, or if an -n value > 95 is specified on the command line. To avoid this, spread threads out equally over the priorities by calculated the number of threads per priority. Tested with all pathological numbers (i.e. mod=0 mod=1, etc) of threads. Ran 10000 times in parallel. Confirmed failure continues to exist without requeue PI (as it should) and success is seen with requeue PI (as it should be). by subrata_modak · 15 years ago
  5. bf29947 prio-wake: Allow for optional locking prior to broadcast: Allow the user to decide if the mutex should be held prior to calling pthread_cond_broadcast(). Default remains the same. Tested with and without the argument as well as with both 0 and 1 passed to the argument. Values other than 0 and 1 will result in locking the mutex. by subrata_modak · 15 years ago

  7. 611fec2 [RESEND][PATCH 3/3] libstats: Modify testcases to call the append function. I am resending the patch after checking with the latest CVS version of LTP. by subrata_modak · 15 years ago
  8. 1897ec4 This set of 3 patches adds a new API stats_container_append to libstats. This function adds new stats_record_t to the record list in stats_container_t. It also replaces the occurrences of data->size with data->index and modifies the test-cases to call the append function. Changelog by subrata_modak · 15 years ago
  9. 504d949 realtime: Fix the pass criterion of pi_perf test case: The pass criterion in pi_perf test case is wrong. It compares the minimum amount of time taken by the low priority thread with the maximum amount of time taken by the high priority thread to calculate the PI delay. Obviously, these min and max don't necessarily happen in the same iteration, resulting in a number of false failures. The correct way is to compare the time taken by low and high priority threads in each iteration and then find the maximum delay experienced by high priority thread across the iterations. This patch implements the change. Additionally, this patch removes lock_wait_dat array, which is not needed anymore as well as makes a couple of messages easier to understand. This patch changes the messages displayed by this test case slightly. They look like the following now: by subrata_modak · 15 years ago
  10. 4ed6f47 realtime: fix parameter name clash in pi-test7 due to memlock option added: Below patch just renames the parameter name for number of mid priority threads in pi-test7 from -m to -x. Original one clashes with our common memlock option used across all RT tests. Also, pi-test7 is already disabled in our default run profile, so this patch can silently update the test without any impact on any other test. Testing Informations: Tested pi-test7 binary with the patch for the changes. Signed-off-by: Gowrishankar <gowrishankar.m@in.ibm.com>. by subrata_modak · 15 years ago
  11. 27fdaaa Realtime: use mlockall optionally in realtime tests: Below patch adds the support to enable memory lock in realtime testcases optionally (with -m). Testing Informations: Tested the realtime tests in their default profile and as well as using mlock option. by subrata_modak · 15 years ago
  12. e6432e4 [real-time] sched_footbal atomic start: The current barrier implementation results in the lowest priority thread actually starting the game (they are the last to be scheduled to call pthread_barrier_wait). This thread likely gets a priority boost as it holds the hb->lock for the futex associated with the barrier. This might lead to it running ahead of the defense threads. In fact, any sort of barrier or cond var implementation (short of a pi aware cond broadcast, which is not yet readily available) will result in a thundering herd situation when the FUTEX_WAKE_ALL syscall is issued, which can result in a short run of one or more offense threads while all the threads get to the RUNNABLE state. This patch removes the complex starting mechansims and replaces them with a simple atomic counter. All player threads are started and once the players_ready count reaches the total player count, the referee starts the game by setting the ball position to zero. Tested on two platforms (both x86_64, 4 and 8-way) for a combined total of 13,000 iterations with 0 failures. Signed-off-by: Darren Hart <dvhltc@us.ibm.com>. by subrata_modak · 15 years ago
  13. 56a3116 Fix faulty interpretation of PASS/FAIL bysched_football log parser: The log parser of sched_football sometimes interprets successful runs as FAILed ones as it gets the final result based on the PASS/FAIL value of the first run in the log file. The rationale behind this patch is that sched_football testcase can itself decide if it has passed or failed based on the_ball value. There is no need of the log parser as is the case with the other test cases like pi_perf. Changelog: by subrata_modak · 15 years ago
  14. 56f4d75 Realtime: fix testpi2 parser from invalid index type error: realtime: fix testpi2 parser from invalid index type error. The patch below fixes invalid array index returned by eval() function in testpi2 parser. While a typical testpi2 logfile, where text fragment "pthread pol 2 pri 10" follows 'Noise Thread' line more than once, is given to testpi2 parser, it exits with error below: by subrata_modak · 16 years ago
  15. 7e66474 Realtime: Usability fix for matrix_mult test case: Here is a simple usability fix for matrix_mult test case. I think this print statement was missed out when the test was written. by subrata_modak · 16 years ago
  16. 503be94 realtime: add time out option to gtod_infinite test: At present, gtod_infinite runs for ever, until we kill the test. This behavior blocks the automated codes to use it as part of running it and generating result graphs. Below patch adds the option to timeout the test after specified hours (-t option, which is for number of hours). With out using this option, test runs for infinite hours which is its default behavior. Also, this patch is first step on gtod_infinite to add it into future patch for long_running tests, where it may be scheduled to run for 3 days.

  18. 4ce8327 Remove references of jvmsim from the tests: Most of the testcases, have an option (-j) which runs the jvmsim as a background load so as to simulate the behavior of the JVM.This patch removes the references of jvmsim from all the testcases.

  19. 39c8f45 The test case gtod_latency in realtime causes soft lockups on some machines. This is because the test hogs the cpus for a long time, because it's main loop runs at SCHED_FIFO, 99. We have seen soft lockups mainly on LS20 machines (x86_64, Opterons). The following patch introduces a sleep after some iterations of the test. This ensures that the test doesn't hog the cpu completely and hence avoids soft lockups. by subrata_modak · 16 years ago

  28. 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

  30. 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.

  32. 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

  36. 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.

  47. 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.

  58. 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
