Rodolfo Giometti authored
This patch adds the kernel side of the PPS support currently named "LinuxPPS". PPS means "pulse per second" and a PPS source is just a device which provides a high precision signal each second so that an application can use it to adjust system clock time. Common use is the combination of the NTPD as userland program with a GPS receiver as PPS source to obtain a wallclock-time with sub-millisecond synchronisation to UTC. To obtain this goal the userland programs shoud use the PPS API specification (RFC 2783 - Pulse-Per-Second API for UNIX-like Operating Systems, Version 1.0) which in part is implemented by this patch. It provides a set of chars devices, one per PPS source, which can be used to get the time signal. The RFC's functions can be implemented by accessing to these char devices. Signed-off-by:

Jack Steiner authored
Fix potential SGI GRU bug that could cause a use-after-free. If one thread in a task is flushing the GRU and another thread destroys the GRU context, there is the potential to access a table after it has been freed. Copy the gms pointer to a local variable before unlocking the gts table. Note that no refcnt is needed for the gms - the reference is held indirectly by the task's mm_struct. Signed-off-by:

Add user function to explicitly unload GRU kernel contexts from the GRU. Only contexts that are not in-use will be unloaded. This function is primarily for testing. It is not expected that this will be used in normal production systems. Signed-off-by:

Fix two problems related to GRU instruction failures. Cache coherency is not maintained for CBEs except when loading or unloading contexts. When reading a CBE to extract error information, the CBE must first be flushed from the cache. The function that reads kerrnel CBEs was reading the wrong CBE. Signed-off-by:

Check whether the gru state being loaded into a gru is from a new context or a previously unloaded context. If new, simply zero out the hardware context; if unloaded and valid, reload the old state.

Change the way GRU resources are assigned for kernel threads. GRU contexts for kernel threads are now allocated on demand and can be stolen by user processes when idle. This allows MPI jobs to use ALL of the GRU resources when the kernel is not using them. Signed-off-by:

Neil Horman authored
Currently the sysrq-c handler is bit over-engineered. Its behavior is dependent on a few compile time and run time factors that alter its behavior which is really unnecessecary. If CONFIG_KEXEC is not configured, sysrq-c, crashes the system with a NULL pointer dereference. If CONFIG_KEXEC is configured, it calls crash_kexec directly, which implies that the kexec kernel will either be booted (if its been previously loaded), or it will simply do nothing (the no kexec kernel has been loaded). It would be much easier to just simplify the whole thing to dereference a NULL pointer all the time regardless of configuration. That way, it will always try to crash the system, and if a kexec kernel has been loaded into reserved space, it will still boot from the page fault trap handler (assuming panic_on_oops is set appropriately).
