| * sched: default to n for GROUP_SCHED and FAIR_GROUP_SCHEDParag Warudkar2008-05-05
| | | | | | | | | | | | | | | | | | | | | | GROUP_SCHED is confirmed to cause unacceptable latencies, see: http://lkml.org/lkml/2008/5/2/370. Mark it EXPERIMENTAL and default to no for now. Signed-off-by: Parag Warudkar <parag.warudkar@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
| * sched: add optional support for CONFIG_HAVE_UNSTABLE_SCHED_CLOCKPeter Zijlstra2008-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this replaces the rq->clock stuff (and possibly cpu_clock()). - architectures that have an 'imperfect' hardware clock can set CONFIG_HAVE_UNSTABLE_SCHED_CLOCK - the 'jiffie' window might be superfulous when we update tick_gtod before the __update_sched_clock() call in sched_clock_tick() - cpu_clock() might be implemented as: sched_clock_cpu(smp_processor_id()) if the accuracy proves good enough - how far can TSC drift in a single jiffie when considering the filtering and idle hooks?

| * sched: fix cpu clockIngo Molnar2008-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | David Miller pointed it out that nothing in cpu_clock() sets prev_cpu_time. This caused __sync_cpu_clock() to be called all the time - against the intention of this code. The result was that in practice we hit a global spinlock every time cpu_clock() is called - which - even though cpu_clock() is used for tracing and debugging, is suboptimal. While at it, also: - move the irq disabling to the outest layer, this should make cpu_clock() warp-free when called with irqs enabled. - use long long instead of cycles_t - for platforms where cycles_t is 32-bit.

| * sched: fair-group: fix a Div0 error of the fair group schedulerMiao Xie2008-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When I echoed 0 into the "cpu.shares" file, a Div0 error occured. We found it is caused by the following calling. sched_group_set_shares(tg, shares) set_se_shares(tg->se[i], shares/nr_cpu_ids) __set_se_shares(se, shares) div64_64((1ULL<<32), shares) When the echoed value was less than the number of processores, the result of the sentence "shares/nr_cpu_ids" was 0, and then the system called div64() to divide the result, the Div0 error occured. It is unnecessary that the shares value is divided by nr_cpu_ids, I think. Because in the function __update_group_shares_cpu() and init_tg_cfs_entry(), the shares value isn't divided by nr_cpu_ids when setting shares of the sched entity. This patch fixes this bug. And echoing ULONG_MAX value into cpu.shares also causes Div0 error, so we set a macro MAX_SHARES to limit the max value of shares.

| * sched: fix missing locking in sched_domains codeHeiko Carstens2008-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Concurrent calls to detach_destroy_domains and arch_init_sched_domains were prevented by the old scheduler subsystem cpu hotplug mutex. When this got converted to get_online_cpus() the locking got broken. Unlike before now several processes can concurrently enter the critical sections that were protected by the old lock. So use the already present doms_cur_mutex to protect these sections again.

| * sched: fix SCHED_FAIR wake-idle logic errorGregory Haskins2008-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We currently use an optimization to skip the overhead of wake-idle processing if more than one task is assigned to a run-queue. The assumption is that the system must already be load-balanced or we wouldnt be overloaded to begin with. The problem is that we are looking at rq->nr_running, which may include RT tasks in addition to CFS tasks. Since the presence of RT tasks really has no bearing on the balance status of CFS tasks, this throws the calculation off. This patch changes the logic to only consider the number of CFS tasks when making the decision to optimze the wake-idle.

| * sched: fix RT task-wakeup logicGregory Haskins2008-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dmitry Adamushko pointed out a logic error in task_wake_up_rt() where we will always evaluate to "true". You can find the thread here: http://lkml.org/lkml/2008/4/22/296 In reality, we only want to try to push tasks away when a wake up request is not going to preempt the current task. So lets fix it. Note: We introduce test_tsk_need_resched() instead of open-coding the flag check so that the merge-conflict with -rt should help remind us that we may need to support NEEDS_RESCHED_DELAYED in the future, too.

| * | | kgdb: 1000 loops for the single step test in kgdbtsJason Wessel2008-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The single step test is not terribly costly and it should be able to pass at 1000 loops successfully in under 1 second. A non-kgdb timing regression was found using this test, but it did not occur frequently because by default the test was only executed a single time. This patch changes the default for the single step test to 1000 iterations and allows for individual configuration of the single step test to further exercise the kgdb subsystem when needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On boards with VT1617A codec, the sound disappears suddenly. This looks like a problem with HPE-bit control that is supposed to be set in patch_vt1617a(). However, on such problematic hardwares, the bit is actually reset mysteriously. The patch adds a workaround for the wrong quirk. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | FM801-tea575x tuner has a reverse selection to V4L1 and this causes nasty dependency problems. The patch simplifies the dependency with a normal "depends on VIDEO_V4L1". This decreases the usability but fixes bugs, yeah. If any better feature like "requires" is introduced to kbuild in future, we'll be able to switch it... Signed-off-by: Takashi Iwai <tiwai@suse.de>
