- Core code:
- Interrupt storm detection for the lockup watchdog:
Lockups which are caused by interrupt storms are not easy to debug
because there is no information about the events which make the lockup
detector trigger.
To make this more user friendly, provide an extenstion to interrupt
statistics which allows to take snapshots and an interface to retrieve
the delta to the snapshot. Use this new mechanism in the watchdog code
to do a two stage lockup analysis by taking the snapshot and printing
the deltas for the topmost active interrupts on the second trigger.
Note: This contains both the interrupt and the watchdog changes as
the latter depend on the former obviously.
- Avoid summation loops in the /proc/interrupts output and use the global
counter when possible
- Skip suspended interrupts on CPU hotplug operations to ensure that they
are not delivered before the system resumes the device drivers when
coming out of suspend.
- On CPU hot-unplug interrupts which are affine to the outgoing CPU are
migrated to a different CPU in the affinity mask. This can fail when
the CPUs have no vectors left. Instead of giving up try to migrate it
to any online CPU and thereby breaking the affinity setting in order to
prevent a stale device interrupt which targets an offline CPU
- The usual small cleanups
- Driver code:
- Support for the RISCV AIA MSI controller
- Make the interrupt allocation for the Loongson PCH controller more
flexible to prevent vector exhaustion
- The usual set of cleanups and fixes all over the place
