score: Rework _Thread_Change_priority() Move the writes to Thread_Control::current_priority and Thread_Control::real_priority into _Thread_Change_priority() under the protection of the thread lock. Add a filter function to _Thread_Change_priority() to enable specialized variants. Avoid race conditions during a thread priority restore with the new Thread_Control::priority_restore_hint for an important average case optimizations used by priority inheritance mutexes. Update #2273.

timecounter: Merge FreeBSD change r282424 Implement a mechanism for making changes in the kernel<->driver PPS interface without breaking ABI or API compatibility with existing drivers. The existing data structures used to communicate between the kernel and driver portions of PPS processing contain no spare/padding fields and no flags field or other straightforward mechanism for communicating changes in the structures or behaviors of the code. This makes it difficult to MFC new features added to the PPS facility. ABI compatibility is important; out-of-tree drivers in module form are known to exist. (Note that the existing api_version field in the pps_params structure must contain the value mandated by RFC 2783 and any RFCs that come along after.) These changes introduce a pair of abi-version fields which are filled in by the driver and the kernel respectively to indicate the interface version. The driver sets its version field before calling the new pps_init_abi() function. That lets the kernel know how much of the pps_state structure is understood by the driver and it can avoid using newer fields at the end of the structure that it knows about if the driver is a lower version. The kernel fills in its version field during the init call, letting the driver know what features and data the kernel supports. To implement the new version information in a way that is backwards compatible with code from before these changes, the high bit of the lightly-used 'kcmode' field is repurposed as a flag bit that indicates the driver is aware of the abi versioning scheme. Basically if this bit is clear that indicates a "version 0" driver and if it is set the driver_abi field indicates the version. These changes also move the recently-added 'mtx' field of pps_state from the middle to the end of the structure, and make the kernel code that uses this field conditional on the driver being abi version 1 or higher. It changes the only driver currently supplying the mtx field, usb_serial, to use pps_init_abi(). Reviewed by: hselasky@ Update #3175.

11:12 Changeset in rtems [cc18d7b]4.115 by Sebastian Huber <sebastian.huber@…>
score: Fine grained locking for message queues Aggregate several critical sections into a bigger one. Sending and receiving messages is now protected by an ISR lock. Thread dispatching is only disabled in case a blocking operation is necessary. The message copy procedure is done inside the critical section (interrupts disabled). Thus this change may have a negative impact on the interrupt latency in case very large messages are transferred. Update #2273.

libmisc/cpuuse: Top support for current load. The cpuuse top command now supports the current load where the list of tasks is ordered based on the current load rather than the total cpu usage. This lets you see what is using the processor at any specific instance. The ability to sort on a range of thread values is now supported. Added memory usage stats for unified and separate workspace and C heaps as well as displaying the allocated stack space. Added a few more command keys to refresh the display, show all tasks in the system, control the lines display and a scrolling mode that does not clear the display on each refresh. Removed support for tick kernel builds. The tick support in the kernel is to be removed.

score: Fix POSIX thread join A thread join is twofold. There is one thread that exists and an arbitrary number of threads that wait for the thread exit (one-to-many relation). The exiting thread may want to wait for a thread that wants to join its exit (STATES_WAITING_FOR_JOIN_AT_EXIT in _POSIX_Thread_Exit()). On the other side we need a thread queue for all the threads that wait for the exit of one particular thread (STATES_WAITING_FOR_JOIN in pthread_join()). Update #2035.
