If the sched_clock time starts at a large value, the kernel will spin in sched_avg_update for a long time while rq->age_stamp catches up with rq->clock. The comment in kernel/sched/clock.c says that there is no strict promise that it starts at zero. So initialize rq->age_stamp when a cpu starts up to avoid this. I was seeing long delays on a simulator that didn't start the clock at zero. This might also be an issue on reboots on processors that don't re-initialize the timer to zero on reset, and when using kexec.

Sometimes ->nr_running may cross 2 but interrupt is not being sent to rq's cpu. In this case we don't reenable the timer. Looks like this may be the reason for rare unexpected effects, if nohz is enabled. Patch replaces all places of direct changing of nr_running and makes add_nr_running() caring about crossing border.

Currently, in idle_balance(), we update rq->next_balance when we pull_tasks. However, it is also important to update this in the !pulled_tasks case too. When the CPU is "busy" (the CPU isn't idle), rq->next_balance gets computed using sd->busy_factor (so we increase the balance interval when the CPU is busy). However, when the CPU goes idle, rq->next_balance could still be set to a large value that was computed with the sd->busy_factor. Thus, we need to also update rq->next_balance in idle_balance() in the cases where !pulled_tasks too, so that rq->next_balance gets updated without taking the busy_factor into account when the CPU is about to go idle. This patch makes rq->next_balance get updated independently of whether or not we pulled_task. Also, we add logic to ensure that we always traverse at least 1 of the sched domains to get a proper next_balance value for updating rq->next_balance. Additionally, since load_balance() modifies the sd->balance_interval, we need to re-obtain the sched domain's interval after the call to load_balance() in rebalance_domains() before we update rq->next_balance. This patch adds and uses 2 new helper functions, update_next_balance() and get_sd_balance_interval() to update next_balance and obtain the sched domain's balance_interval.

Jet Chen has reported a kernel panics when booting qemu-system-x86_64 with kvm64 cpu. A panic occured while building the sched_domain. In sched_init_numa, we create a new topology table in which both default levels and numa levels are copied. The last row of the table must have a null pointer in the mask field. The current implementation doesn't add this last row in the computation of the table size. So we add 1 row in the allocation size that will be used as the last row of the table. The kzalloc will ensure that the mask field is NULL.

由 Rik van Riel 提交于
On smaller systems, the top level sched domain will be an affine domain, and select_idle_sibling is invoked for every SD_WAKE_AFFINE wakeup. This seems to be working well. On larger systems, with the node distance between far away NUMA nodes being > RECLAIM_DISTANCE, select_idle_sibling is only called if the waker and the wakee are on nodes less than RECLAIM_DISTANCE apart. This patch leaves in place the policy of not pulling the task across nodes on such systems, while fixing the issue that select_idle_sibling is not called at all in certain circumstances. The code will look for an idle CPU in the same CPU package as the CPU where the task ran previously.

task_hot checks exec_start on any runnable task, but if it has been migrated since the it last ran, then exec_start is a clock_task from another cpu. If the old cpu's clock_task was sufficiently far ahead of this cpu's then the task will not be considered for another migration until it has run. Instead reset exec_start whenever a task is migrated, since it is presumably no longer hot anyway.

由 Juri Lelli 提交于
Michael Kerrisk noticed that creating SCHED_DEADLINE reservations with certain parameters (e.g, a runtime of something near 2^64 ns) can cause a system freeze for some amount of time. The problem is that in the interface we have u64 sched_runtime; while internally we need to have a signed runtime (to cope with budget overruns) s64 runtime; At the time we setup a new dl_entity we copy the first value in the second. The cast turns out with negative values when sched_runtime is too big, and this causes the scheduler to go crazy right from the start. Moreover, considering how we deal with deadlines wraparound (s64)(a - b) < 0 we also have to restrict acceptable values for sched_{deadline,period}. This patch fixes the thing checking that user parameters are always below 2^63 ns (still large enough for everyone). It also rewrites other conditions that we check, since in __checkparam_dl we don't have to deal with deadline wraparounds and what we have now erroneously fails when the difference between values is too big.

The documented[1] behavior of sched_attr() in the proposed man page text is: sched_attr::size must be set to the size of the structure, as in sizeof(struct sched_attr), if the provided structure is smaller than the kernel structure, any additional fields are assumed '0'. If the provided structure is larger than the kernel structure, the kernel verifies all additional fields are '0' if not the syscall will fail with -E2BIG. As currently implemented, sched_copy_attr() returns -EFBIG for for this case, but the logic in sys_sched_setattr() converts that error to -EFAULT. This patch fixes the behavior.

Pull clock framework fixes from Mike Turquette: "Clock framework and driver fixes, all of which fix user-visible regressions. As usual most fixes are for platform-specific clock drivers, but there are also two fixes to the clk core after recent changes to the way that clock unregistration is handled" * tag 'clk-fixes-for-linus' of git://git.linaro.org/people/mike.turquette/linux: clk: tegra: Fix wrong value written to PLLE_AUX clk: shmobile: clk-mstp: change to using clock-indices clk: Fix slab corruption in clk_unregister() clk: Fix double free due to devm_clk_register() clk: socfpga: fix clock driver for 3.15 clk: divider: Fix best div calculation for power-of-two and table dividers clk: bcm281xx: don't use unnamed structs or unions

Pull spi fixes from Mark Brown: "A few core fixes around outlying cases here, nothing that should affect most users but useful fixes. The diffstat is rather larger than one might hope due some simple code motion in the fix for !CONFIG_DMA, the actual meaningful change is much smaller. - Fix handling of unsupported dual and quad mode support on slave registration so that drivers that can degrade gracefully do so, preventing regressions for drivers this is added. - Fix build in !CONFIG_DMA cases following addition of generic DMA mapping support. - Fix error handling for queue creation which due to wider kernel changes can be triggered more easily. - A couple of driver specific fixes" * tag 'spi-v3.15-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: spi/pxa2xx: Prevent DMA from transferring too many bytes spi: core: Don't destroy master queue if we fail to create it spi: qup: Fix return value checking for pm_runtime_get_sync() spi: core: Protect DMA code by #ifdef CONFIG_HAS_DMA spi: core: Ignore unsupported Dual/Quad Transfer Mode bits
