2005-09-07[PATCH] detect soft lockupsIngo Molnar
This patch adds a new kernel debug feature: CONFIG_DETECT_SOFTLOCKUP. When enabled then per-CPU watchdog threads are started, which try to run once per second. If they get delayed for more than 10 seconds then a callback from the timer interrupt detects this condition and prints out a warning message and a stack dump (once per lockup incident). The feature is otherwise non-intrusive, it doesnt try to unlock the box in any way, it only gets the debug info out, automatically, and on all CPUs affected by the lockup.

2005-09-07[PATCH] 3c59x PM fixesRafael J. Wysocki
This patch adds some missing pci-related calls to the suspend and resume routines of the 3c59x driver. It also makes the driver free/request IRQ on suspend/resume, in accordance with the proposal at: http://lists.osdl.org/pipermail/linux-pm/2005-May/000955.html Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-07[PATCH] x86/x86_64: deferred handling of writes to /proc/irqxx/smp_affinityAshok Raj
When handling writes to /proc/irq, current code is re-programming rte entries directly. This is not recommended and could potentially cause chipset's to lockup, or cause missing interrupts. CONFIG_IRQ_BALANCE does this correctly, where it re-programs only when the interrupt is pending. The same needs to be done for /proc/irq handling as well. Otherwise user space irq balancers are really not doing the right thing. - Changed pending_irq_balance_cpumask to pending_irq_migrate_cpumask for lack of a generic name. - added move_irq out of IRQ_BALANCE, and added this same to X86_64 - Added new proc handler for write, so we can do deferred write at irq handling time. - Display of /proc/irq/XX/smp_affinity used to display CPU_MASKALL, instead it now shows only active cpu masks, or exactly what was set. - Provided a common move_irq implementation, instead of duplicating when using generic irq framework. Tested on i386/x86_64 and ia64 with CONFIG_PCI_MSI turned on and off. Tested UP builds as well. MSI testing: tbd: I have cards, need to look for a x-over cable, although I did test an earlier version of this patch. Will test in a couple days.

2005-09-05[SPARC64]: Kconfig fix (GEN_RTC dependencies)Al Viro
Yet another architecture not coverd by GEN_RTC - sparc64 never picked it until now and it doesn't have asm/rtc.h to go with it, so it wouldn't compile anyway (or have these ioctls in the user-visible headers, for that matter). FWIW, I'm very tempted to introduce ARCH_HAS_GEN_RTC and have it set in arch/*/Kconfig for architectures that know what to do with this stuff - for something supposedly generic the list of architectures where it doesn't work is getting too long...

2005-09-05[TG3]: Use status tag to check for new eventsMichael Chan
Use the status tag to determine if there are new events in tg3_interrupt_tagged(). We discussed about this a while ago with Grant Grundler and DaveM. This scheme makes it unnecessary to clear the updated bit in the status block when using tagged mode, and only a simple comparison is needed to determine if there are new events. The tp->lock around netif_rx_complete() and tg3_restart_ints() is also removed. It is unnecessary with DaveM's new locking scheme.

2005-09-05[TG3]: Remove status block access in tg3_msi() and add prefetchesMichael Chan
Remove unnecessary status block accesses in tg3_msi(). Since MSI is not shared, it is unnecessary to read the status block to determine if there are any new events in the MSI handler. It is also unnecessary to clear the updated bit in the status block. Since the poll list is per-cpu, tg3_poll() will be scheduled to run on the same CPU that received the MSI. Prefetches for the status block and the next rx descriptors are added in tg3_msi() to improve their access times when tg3_poll() runs. In the non-MSI irq handlers, we need to check the status block because interrupts may be shared. Only prefetches for the next rx descriptors are added.
