++ * When a high priority task schedules out from a CPU and a lower priority |
7092 |
++ * task is scheduled in, a check is made to see if there's any RT tasks |
7093 |
++ * on other CPUs that are waiting to run because a higher priority RT task |
7094 |
++ * is currently running on its CPU. In this case, the CPU with multiple RT |
7095 |
++ * tasks queued on it (overloaded) needs to be notified that a CPU has opened |
7096 |
++ * up that may be able to run one of its non-running queued RT tasks. |
7097 |
++ * |
7098 |
++ * All CPUs with overloaded RT tasks need to be notified as there is currently |
7099 |
++ * no way to know which of these CPUs have the highest priority task waiting |
7100 |
++ * to run. Instead of trying to take a spinlock on each of these CPUs, |
7101 |
++ * which has shown to cause large latency when done on machines with many |
7102 |
++ * CPUs, sending an IPI to the CPUs to have them push off the overloaded |
7103 |
++ * RT tasks waiting to run. |
7104 |
++ * |
7105 |
++ * Just sending an IPI to each of the CPUs is also an issue, as on large |
7106 |
++ * count CPU machines, this can cause an IPI storm on a CPU, especially |
7107 |
++ * if its the only CPU with multiple RT tasks queued, and a large number |
7108 |
++ * of CPUs scheduling a lower priority task at the same time. |
7109 |
++ * |
7110 |
++ * Each root domain has its own irq work function that can iterate over |
7111 |
++ * all CPUs with RT overloaded tasks. Since all CPUs with overloaded RT |
7112 |
++ * tassk must be checked if there's one or many CPUs that are lowering |
7113 |
++ * their priority, there's a single irq work iterator that will try to |
7114 |
++ * push off RT tasks that are waiting to run. |
7115 |
++ * |
7116 |
++ * When a CPU schedules a lower priority task, it will kick off the |
7117 |
++ * irq work iterator that will jump to each CPU with overloaded RT tasks. |
7118 |
++ * As it only takes the first CPU that schedules a lower priority task |
7119 |
++ * to start the process, the rto_start variable is incremented and if |
7120 |
++ * the atomic result is one, then that CPU will try to take the rto_lock. |
7121 |
++ * This prevents high contention on the lock as the process handles all |
7122 |
++ * CPUs scheduling lower priority tasks. |
7123 |
++ * |
7124 |
++ * All CPUs that are scheduling a lower priority task will increment the |
7125 |
++ * rt_loop_next variable. This will make sure that the irq work iterator |
7126 |
++ * checks all RT overloaded CPUs whenever a CPU schedules a new lower |
7127 |
++ * priority task, even if the iterator is in the middle of a scan. Incrementing |
7128 |

7224 |
+- * When a high priority task schedules out from a CPU and a lower priority |
7225 |
+- * task is scheduled in, a check is made to see if there's any RT tasks |
7226 |
+- * on other CPUs that are waiting to run because a higher priority RT task |
7227 |
+- * is currently running on its CPU. In this case, the CPU with multiple RT |
7228 |
+- * tasks queued on it (overloaded) needs to be notified that a CPU has opened |
7229 |
+- * up that may be able to run one of its non-running queued RT tasks. |
7230 |
+- * |
7231 |
+- * On large CPU boxes, there's the case that several CPUs could schedule |
7232 |
+- * a lower priority task at the same time, in which case it will look for |
7233 |
+- * any overloaded CPUs that it could pull a task from. To do this, the runqueue |
7234 |
+- * lock must be taken from that overloaded CPU. Having 10s of CPUs all fighting |
7235 |
+- * for a single overloaded CPU's runqueue lock can produce a large latency. |
7236 |
+- * (This has actually been observed on large boxes running cyclictest). |
7237 |
+- * Instead of taking the runqueue lock of the overloaded CPU, each of the |
7238 |
+- * CPUs that scheduled a lower priority task simply sends an IPI to the |
7239 |
+- * overloaded CPU. An IPI is much cheaper than taking an runqueue lock with |
7240 |
+- * lots of contention. The overloaded CPU will look to push its non-running |
7241 |
+- * RT task off, and if it does, it can then ignore the other IPIs coming |
7242 |
+- * in, and just pass those IPIs off to any other overloaded CPU. |
7243 |
+- * |
7244 |
+- * When a CPU schedules a lower priority task, it only sends an IPI to |
7245 |
+- * the "next" CPU that has overloaded RT tasks. This prevents IPI storms, |
7246 |
+- * as having 10 CPUs scheduling lower priority tasks and 10 CPUs with |
7247 |
+- * RT overloaded tasks, would cause 100 IPIs to go out at once. |
7248 |
+- * |
7249 |
+- * The overloaded RT CPU, when receiving an IPI, will try to push off its |
7250 |
+- * overloaded RT tasks and then send an IPI to the next CPU that has |
7251 |
+- * overloaded RT tasks. This stops when all CPUs with overloaded RT tasks |
7252 |
+- * have completed. Just because a CPU may have pushed off its own overloaded |
7253 |
+- * RT task does not mean it should stop sending the IPI around to other |
7254 |
+- * overloaded CPUs. There may be another RT task waiting to run on one of |
7255 |
+- * those CPUs that are of higher priority than the one that was just |
7256 |
+- * pushed. |
7257 |
+- * |
7258 |
+- * An optimization that could possibly be made is to make a CPU array similar |
7259 |
+- * to the cpupri array mask of all running RT tasks, but for the overloaded |
7260 |
+- * case, then the IPI could be sent to only the CPU with the highest priority |
7261 |
+- * RT task waiting, and that CPU could send off further IPIs to the CPU with |
7262 |
+- * the next highest waiting task. Since the overloaded case is much less likely |
7263 |
+- * to happen, the complexity of this implementation may not be worth it. |
7264 |
+- * Instead, just send an IPI around to all overloaded CPUs. |
7265 |
+- * |
7266 |
+- * The rq->rt.push_flags holds the status of the IPI that is going around. |
7267 |
+- * A run queue can only send out a single IPI at a time. The possible flags |
7268 |
+- * for rq->rt.push_flags are: |
7269 |
+- * |
7270 |
+- * (None or zero): No IPI is going around for the current rq |
7271 |
+- * RT_PUSH_IPI_EXECUTING: An IPI for the rq is being passed around |
7272 |
+- * RT_PUSH_IPI_RESTART: The priority of the running task for the rq |
7273 |
+- * has changed, and the IPI should restart |
7274 |
+- * circulating the overloaded CPUs again. |
7275 |
+- * |
7276 |
+- * rq->rt.push_cpu contains the CPU that is being sent the IPI. It is updated |
7277 |
+- * before sending to the next CPU. |
7278 |
+- * |
7279 |
+- * Instead of having all CPUs that schedule a lower priority task send |
7280 |
+- * an IPI to the same "first" CPU in the RT overload mask, they send it |
7281 |
+- * to the next overloaded CPU after their own CPU. This helps distribute |
7282 |
+- * the work when there's more than one overloaded CPU and multiple CPUs |
7283 |
+- * scheduling in lower priority tasks. |
7284 |
+- * |
7285 |
+- * When a rq schedules a lower priority task than what was currently |
7286 |
+- * running, the next CPU with overloaded RT tasks is examined first. |
7287 |
+- * That is, if CPU 1 and 5 are overloaded, and CPU 3 schedules a lower |
7288 |
+- * priority task, it will send an IPI first to CPU 5, then CPU 5 will |
7289 |
+- * send to CPU 1 if it is still overloaded. CPU 1 will clear the |
7290 |
+- * rq->rt.push_flags if RT_PUSH_IPI_RESTART is not set. |
7291 |
+- * |
7292 |
+- * The first CPU to notice IPI_RESTART is set, will clear that flag and then |
7293 |
+- * send an IPI to the next overloaded CPU after the rq->cpu and not the next |
7294 |
+- * CPU after push_cpu. That is, if CPU 1, 4 and 5 are overloaded when CPU 3 |
7295 |
+- * schedules a lower priority task, and the IPI_RESTART gets set while the |
7296 |
+- * handling is being done on CPU 5, it will clear the flag and send it back to |
7297 |
+- * CPU 4 instead of CPU 1. |
7298 |
+- * |
7299 |
+- * Note, the above logic can be disabled by turning off the sched_feature |
7300 |
+- * RT_PUSH_IPI. Then the rq lock of the overloaded CPU will simply be |
7301 |
+- * taken by the CPU requesting a pull and the waiting RT task will be pulled |
7302 |
+- * by that CPU. This may be fine for machines with few CPUs. |
