zefir	713e8be629	move CPU chipset specific optimization into device-cpu	13 years ago
Luke Dashjr	b9d197dee8	Refactor the CPU scanhash_* functions to use a common API. Fixes bugs. - 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.	13 years ago

Con Kolivas	5007805d1f	Update CPU reentrant scan code to work properly for extended periods up to scantime and adjust rate properly. Simplify locking in hashmeter since it's called relatively infrequently anyway. Set gpuminer hashmeter interval update to log interval / 5 as well.	14 years ago
Ycros	9fe2106467	Fixed up using config.h instead of cpuminer-config.h.	14 years ago
ckolivas	262b98ca95	Linux + x86_64 optimisations. 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.	14 years ago
Jeff Garzik	23e9cf91f0	Ensure cpuminer-config.h is universally included, in .c and .h alike. In miner.h, this fixes an alloca-definition-related warning. For the other files, this is simply future-proofing/precaution.	14 years ago
