- Before, some returned bool, and others returned int (which was then turned
into a bool with a comparison); now, everything returns a bool
- Before, some set hashes_done to nonce - 1 when a share was found and others
set it to nonce + 1 or 2. This caused some algorithms to scan/submit shares
twice with the new cpu_scanhash function. Now, it has all been replaced with
last_nonce, which is set to the final nonce checked by the scanhash_* func.
- VIA needs the full data, and cannot use midstate. All the others were
expecting midstate and data+64 for their parameters. Now, we pass midstate
and the full data pointer, and let the scanhash_* function choose which to
use.
Add likely() macro.
Optimise a few obvious code paths with likely/unlikely.
Change algo to sse2_amd64 by default.
Move priority change to worker threads only.
Detect number of CPUs and set default number of threads == CPUs.
Add scheduling policy change to worker threads to SCHED_IDLE first and fallback to SCHED_BATCH on linux.
Don't error when failing to set priority.
Add CPU affinity and bind worker threads to CPUs when number of threads is a multiple of number of CPUs.
Update NEWS with changes.
