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	5133cf5b06	Add altivec 4 way support courtesy of Gilles Risch.	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
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

Raulo	a27e69aec5	Changes to make the 4-way code compile on Intel Compiler	14 years ago
Jeff Garzik	1083e15c47	Mark hash success as unlikely, using __builtin_expect() intrinsic	14 years ago
Jeff Garzik	714c0fd7c9	Continue scanhash, even if high 32 bits are zero. Previously, we would stop the scan if the high 32 bits of the hash were zero, as a quick shortcut for testing the full hash. If this quick test succeeded, we would pass the work to the server for full validation. Change this logic to perform full validation inside minerd, so that work may be resumed more quickly if hash > target.	14 years ago

Jeff Garzik	0b67740707	Pass max-nonce as arg to each sha256 algo. Should be an equivalent transformation, with no behavior changes.	14 years ago
