Raw Normal View History

Linux-2.6.12-rc2 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!

[PATCH] x86: Cleanup NMI interrupt path 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>

[PATCH] Fix up panic messages for different NMI panics When a unknown NMI happened the panic would claim a NMI watchdog timeout. Also it would check the variable set by nmi_watchdog=panic and panic then. Fix up the panic message to be generic Unconditionally panic on unknown NMI when panic on unknown nmi is enabled.

[PATCH] x86_64: Collected NMI watchdog fixes. Collected NMI watchdog fixes. - Fix call of check_nmi_watchdog - Remove earlier move of check_nmi_watchdog to later. It does not fix the race it was supposed to fix fully. - Remove unused P6 definitions - Add support for performance counter based watchdog on P4 systems. This allows to run it only once per second, which saves some CPU time. Previously it would run at 1000Hz, which was too much. Code ported from i386 Make this the default on Intel systems. - Use check_nmi_watchdog with local APIC based nmi - Fix race in touch_nmi_watchdog - Fix bug that caused incorrect performance counters to be programmed in a few cases on K8. - Remove useless check for local APIC - Use local_t and per_cpu variables for per CPU data. - Keep other CPUs busy during check_nmi_watchdog to make sure they really tick when in lapic mode. - Only check CPUs that are actually online. - Various other fixes. - Fix fallback path when MSRs are unimplemented Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

[PATCH] x86: Add performance counter reservation framework for UP kernels 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>
