| * | | sched: fix bug in balance_tasks()Peter Williams2007-08-095-54/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two problems with balance_tasks() and how it used: 1. The variables best_prio and best_prio_seen (inherited from the old move_tasks()) were only required to handle problems caused by the active/expired arrays, the order in which they were processed and the possibility that the task with the highest priority could be on either. These issues are no longer present and the extra overhead associated with their use is unnecessary (and possibly wrong). 2. In the absence of CONFIG_FAIR_GROUP_SCHED being set, the same this_best_prio variable needs to be used by all scheduling classes or there is a risk of moving too much load. E.g. if the highest priority task on this at the beginning is a fairly low priority task and the rt class migrates a task (during its turn) then that moved task becomes the new highest priority task on this_rq but when the sched_fair class initializes its copy of this_best_prio it will get the priority of the original highest priority task as, due to the run queue locks being held, the reschedule triggered by pull_task() will not have taken place. This could result in inappropriate overriding of skip_for_load and excessive load being moved. The attached patch addresses these problems by deleting all reference to best_prio and best_prio_seen and making this_best_prio a reference parameter to the various functions involved. load_balance_fair() has also been modified so that this_best_prio is only reset (in the loop) if CONFIG_FAIR_GROUP_SCHED is set. This should preserve the effect of helping spread groups' higher priority tasks around the available CPUs while improving system performance when CONFIG_FAIR_GROUP_SCHED isn't set.

The first of these capabilities is used in two places, load_balance() and load_balance_idle(), and in both of these cases the return value of move_tasks() is used purely to decide if tasks/load were moved and no notice of the actual number of tasks moved is taken. The second capability is used in exactly one place, active_load_balance(), to attempt to move exactly one task and, as before, the return value is only used as an indicator of success or failure. This multiplexing of sched_task() was introduced, by me, as part of the smpnice patches and was motivated by the fact that the alternative, one function to move specified load and one to move a single task, would have led to two functions of roughly the same complexity as the old move_tasks() (or the new balance_tasks()). However, the new modular design of the new CFS scheduler allows a simpler solution to be adopted and this patch addresses that solution by: 1. adding a new function, move_one_task(), to be used by active_load_balance(); and 2. making move_tasks() a single purpose function that tries to move a specified weighted load and returns 1 for success and 0 for failure. One of the consequences of these changes is that neither move_one_task() or the new move_tasks() care how many tasks sched_class.load_balance() moves and this enables its interface to be simplified by returning the amount of load moved as its result and removing the load_moved pointer from the argument list. This helps simplify the new move_tasks() and slightly reduces the amount of work done in each of sched_class.load_balance()'s implementations. Further simplification, e.g. changes to balance_tasks(), are possible but (slightly) complicated by the special needs of load_balance_fair() so I've left them to a later patch (if this one gets accepted). NB Since move_tasks() gets called with two run queue locks held even small reductions in overhead are worthwhile. [ mingo@elte.hu ] this change also reduces code size nicely: text data bss dec hex filename 39216 3618 24 42858 a76a sched.o.before 39173 3618 24 42815 a73f sched.o.after Signed-off-by: Peter Williams <pwil3058@bigpond.net.au> Signed-off-by: Ingo Molnar <mingo@elte.hu>
| * | | sched: reorder update_cpu_load(rq) with the ->task_tick() callIngo Molnar2007-08-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Peter Williams suggested to flip the order of update_cpu_load(rq) with the ->task_tick() call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a Guest makes hypercall which sets a GDT entry to not present, we currently set any segment registers using that GDT entry to 0. Unfortunately, this is not sufficient: there are other ways of altering GDT entries which will cause a fault. The correct solution to do what Linux does: let them set any GDT value they want and handle the #GP when popping causes a fault. This has the added benefit of making our Switcher slightly more robust in the case of any other bugs which cause it to fault. We kill the Guest if it causes a fault in the Switcher: it's the Guest's responsibility to make sure it's not using segments when it changes them.

* | | Fix non-TSC guest clocksource lockupRusty Russell2007-08-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lguest uses a host-supplied wallclock-based clocksource when the TSC is not reliable. As this is already in nanoseconds, I naively used a multiplier of 1 and a shift of 0. But update_wall_time() in its infinite wisdom decides to adjust the clock a little (where does it think it's getting a more accurate time from?) It will happily tweak the multiplier... to 0, then -1. So the "fix" is to use a shift of 22 like everyone else, and a multiplier of 1 << 22.

| * | | r8169: avoid needless NAPI poll schedulingFrancois Romieu2007-08-071-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Theory : though needless, it should not have hurt. Practice: it does not play nice with DEBUG_SHIRQ + LOCKDEP + UP (see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=242572). The patch makes sense in itself but I should dig why it has an effect on #242572 (assuming that NAPI do not change in a near future).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix extracted from Realtek's driver (8.002.00/20070713) for the PHY attached to 8111/8168b chipsets. The check against mac_version is just usual paranoia during the bugfix period of the kernel cycle. -- FR Tested on Asus M2A-VM motherboard by Roger So. No regression on my Asrock 945G DVI either (built-in 8168 + 2x8169).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The essid wireless extension does deadlock against the assoc mutex, as we don't unlock the assoc mutex when flushing the workqueue, which also holds the lock.
