2006-09-30[PATCH] x86: Clean up x86 NMI sysctlsAndi Kleen
Use prototypes in headers Don't define panic_on_unrecovered_nmi for all architectures Cc: dzickus@redhat.com Signed-off-by: Andi Kleen <ak@suse.de>
2006-09-26[PATCH] i386/x86-64: Fix NMI watchdog suspend/resumeShaohua Li
Making NMI suspend/resume work with SMP. We use CPU hotplug to offline APs in SMP suspend/resume. Only BSP executes sysdev's .suspend/.resume method. APs should follow CPU hotplug code path. And: +From: Don Zickus <dzickus@redhat.com> Makes the start/stop paths of nmi watchdog more robust to handle the suspend/resume cases more gracefully.

2006-09-26[PATCH] x86: Add abilty to enable/disable nmi watchdog with sysctlDon Zickus
Adds a new /proc/sys/kernel/nmi call that will enable/disable the nmi watchdog. Signed-off-by: Don Zickus <dzickus@redhat.com> Signed-off-by: Andi Kleen <ak@suse.de>
2006-09-26[PATCH] i386/x86-64: Remove un/set_nmi_callback and ↵Don Zickus
reserve/release_lapic_nmi functions Removes the un/set_nmi_callback and reserve/release_lapic_nmi functions as they are no longer needed. The various subsystems are modified to register with the die_notifier instead. Also includes compile fixes by Andrew Morton.

2006-09-26[PATCH] x86: Cleanup NMI interrupt pathDon Zickus
This patch cleans up the NMI interrupt path. Instead of being gated by if the 'nmi callback' is set, the interrupt handler now calls everyone who is registered on the die_chain and additionally checks the nmi watchdog, reseting it if enabled. This allows more subsystems to hook into the NMI if they need to (without being block by set_nmi_callback). Signed-off-by: Don Zickus <dzickus@redhat.com> Signed-off-by: Andi Kleen <ak@suse.de>
2006-09-26[PATCH] i386: Add SMP support on i386 to reservation frameworkDon Zickus
This patch includes the changes to make the nmi watchdog on i386 SMP aware. A bunch of code was moved around to make it simpler to read. In addition, it is now possible to determine if a particular NMI was the result of the watchdog or not. This feature allows the kernel to filter out unknown NMIs easier.

2006-09-26[PATCH] x86: Add performance counter reservation framework for UP kernelsDon Zickus
Adds basic infrastructure to allow subsystems to reserve performance counters on the x86 chips. Only UP kernels are supported in this patch to make reviewing easier. The SMP portion makes a lot more changes. Think of this as a locking mechanism where each bit represents a different counter. In addition, each subsystem should also reserve an appropriate event selection register that will correspond to the performance counter it will be using (this is mainly neccessary for the Pentium 4 chips as they break the 1:1 relationship to performance counters). This will help prevent subsystems like oprofile from interfering with the nmi watchdog. Signed-off-by: Don Zickus <dzickus@redhat.com> Signed-off-by: Andi Kleen <ak@suse.de>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
