20:22 Changeset in rtems [9bfad8c]5 by Sebastian Huber <sebastian.huber@…>
score: Add thread priority to scheduler nodes The thread priority is manifest in two independent areas. One area is the user visible thread priority along with a potential thread queue. The other is the scheduler. Currently, a thread priority update via _Thread_Change_priority() first updates the user visble thread priority and the thread queue, then the scheduler is notified if necessary. The priority is passed to the scheduler via a local variable. A generation counter ensures that the scheduler discards out-of-date priorities. This use of a local variable ties the update in these two areas close together. For later enhancements and the OMIP locking protocol implementation we need more flexibility. Add a thread priority information block to Scheduler_Node and synchronize priority value updates via a sequence lock on SMP configurations. Update #2556.

Consistently use an unsigned int for computation, due to the usual integer promotion rules. Make Priority_bit_map_Word definition architecture-independent and define it to uint16_t. This was already the case for all architectures except PowerPC. Adjust the PowerPC bitmap support accordingly.

06:15 Changeset in rtems [3ad5f86]5 by Sebastian Huber <sebastian.huber@…>
rtems: Fix no protocol mutex release The Classic binary semaphores without a locking protocol (RTEMS_BINARY_SEMAPHORE) could be released by everyone, e.g. in contrast to the POSIX mutexes (all variants) or the Classic binary semphores with priority inheritance or ceiling, there was no owner check in the release path. This behaviour was a bit unexpected and not documented. Add an owner check to the release path. Update sptests/sp42 accordingly. This change has nothing to do with the simple binary semaphores (RTEMS_SIMPLE_BINARY_SEMAPHORE) which have no owner at all. Update #2725

Retune SHA2 code for improved performance on CPUs with more ILP and a preference for memory load instructions over large code footprints with embedded immediate variables. On amd64 CPUs from 2007-2008 there is not a significant change, but amd64 CPUs from 2009-2010 get roughly 10% more throughput with this code; amd64 CPUs from 2011-2012 get roughly 15% more throughput; and AMD64 CPUs from 2013-2015 get 20-25% more throughput. The Raspberry Pi 2 increases its throughput by 6-8%. Sponsored by: Tarsnap Backup Inc. Performance tested by: allanjude MFC after: 3 weeks

16:06 Changeset in rtems [7b4296e] by Allan Jude <allanjude@…>
Implement SHA-512 truncated (224 and 256 bits) This implements SHA-512/256, which generates a 256 bit hash by calculating the SHA-512 then truncating the result. A different initial value is used, making the result different from the first 256 bits of the SHA-512 of the same input. SHA-512 is ~50% faster than SHA-256 on 64bit platforms, so the result is a faster 256 bit hash. The main goal of this implementation is to enable support for this faster hashing algorithm in ZFS. The feature was introduced into ZFS in r289422, but is disconnected because SHA-512/256 support was missing. A further commit will enable it in ZFS.
