Luke Dashjr e131dfab 2012-03-13T12:18:23 Unify drivers as driver-*.c and add driver name to API
zefir 713e8be6 2012-02-04T14:22:47 move CPU chipset specific optimization into device-cpu
Luke Dashjr b9d197de 2012-01-17T16:29:01 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.
Con Kolivas 48f07d92 2011-08-24T23:07:46 Update to latest sse2 code from cpuminer-ng.
Con Kolivas 0aa98873 2011-07-18T11:27:58 Add an sse4 algorithm to CPU mining.
Ycros 9fe21064 2011-06-25T08:18:29 Fixed up using config.h instead of cpuminer-config.h.
Con Kolivas 5007805d 2011-07-03T19:10:59 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.
ckolivas 262b98ca 2011-06-09T11:45:06 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.
Jeff Garzik 23e9cf91 2011-03-20T22:44:25 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.
Jeff Garzik 2d49a9a5 2011-03-17T22:02:28 Introduce ability to interrupt hash scanners in the middle of scanning.
Jeff Garzik cdb4cd9c 2011-03-14T21:48:15 sha256_*.c: trim trailing whitespace
Jeff Garzik 6b19b15a 2011-03-07T00:23:12 Fix warnings in sse2_64 implementation.
Mark Crichton 96d2287c 2011-03-05T22:22:57 X86_64 SSE2 support for Linux
