* Kick CPUS that might be sleeping in cpus_idle_waitSteven Rostedt2008-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sometimes cpu_idle_wait gets stuck because it might miss CPUS that are already in idle, have no tasks waiting to run and have no interrupts going to them. This is common on bootup when switching cpu idle governors. This patch gives those CPUS that don't check in an IPI kick. Background: ----------- I notice this while developing the mcount patches, that every once in a while the system would hang. Looking deeper, the hang was always at boot up when registering init_menu of the cpu_idle menu governor. Talking with Thomas Gliexner, we discovered that one of the CPUS had no timer events scheduled for it and it was in idle (running with NO_HZ). So the CPU would not set the cpu_idle_state bit. Hitting sysrq-t a few times would eventually route the interrupt to the stuck CPU and the system would continue. Note, I would have used the PDA isidle but that is set after the cpu_idle_state bit is cleared, and would leave a window open where we may miss being kicked. hmm, looking closer at this, we still have a small race window between clearing the cpu_idle_state and disabling interrupts (hence the RFC). CPU0: CPU 1: --------- --------- cpu_idle_wait(): cpu_idle(): | __cpu_cpu_var(is_idle) = 1; | if (__get_cpu_var(cpu_idle_state)) /* == 0 */ per_cpu(cpu_idle_state, 1) = 1; | if (per_cpu(is_idle, 1)) /* == 1 */ | smp_call_function(1) | | receives ipi and runs do_nothing. wait on map == empty idle(); /* waits forever */ So really we need interrupts off for most of this then. One might think that we could simply clear the cpu_idle_state from do_nothing, but I'm assuming that cpu_idle governors can be removed, and this might cause a race that a governor might be used after the module was removed. Venki said: I think your RFC patch is the right solution here. As I see it, there is no race with your RFC patch. As long as you call a dummy smp_call_function on all CPUs, we should be OK. We can get rid of cpu_idle_state and the current wait forever logic altogether with dummy smp_call_function. And so there wont be any wait forever scenario. The whole point of cpu_idle_wait() is to make all CPUs come out of idle loop atleast once. The caller will use cpu_idle_wait something like this. // Want to change idle handler - Switch global idle handler to always present default_idle - call cpu_idle_wait so that all cpus come out of idle for an instant and stop using old idle pointer and start using default idle - Change the idle handler to a new handler - optional cpu_idle_wait if you want all cpus to start using the new handler immediately. Maybe the below 1s patch is safe bet for .24. But for .25, I would say we just replace all complicated logic by simple dummy smp_call_function and remove cpu_idle_state altogether.

But only the phy stuff is required to get a working network. This should go into the kernel because its appearently impossible to boot the script via tftp and then load the real boot binary (yaboot or zimage).

So print the warning just once. In 2.6.25 we'll get rid of the limits altogether and these warnings will vanish with them. http://bugzilla.kernel.org/show_bug.cgi?id=9535 Signed-off-by: Len Brown <len.brown@intel.com>

But some people's scripts (ie: Mark's) were writing to it. As an unhappy compromise, make max_cstate writeable again if the kernel was configured without CONFIG_CPU_IDLE. http://bugzilla.kernel.org/show_bug.cgi?id=9683 Signed-off-by: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Cc: Mark Lord <lkml@rtr.ca> Cc: Arjan van de Ven <arjan@infradead.org> Cc: Ingo Molnar <mingo@elte.hu> Cc: "Rafael J.

It also added a test and a complaint when a machine exceeded the limit, causing: pnpacpi: exceeded the max number of IO resources: 24 http://bugzilla.kernel.org/show_bug.cgi?id=9535 We should have been squawking about this all along, as this is a potentially serious issue. For now, simply burn some dynamic bytes and increase the limit by another 16 to 40. There is no guarantee that this will satisfy every system on Earth. It probably will not, but it should be an improvement. In the future, PNPACPI should allocate resource structures as needed, rather than max-sized arrays.
