Noel Maersk	87801c2578	opencl: rename cgpu_info->kname to cgpu_info->kernelname.	11 years ago
Noel Maersk	1333ed576d	core: simplify kernel selection code. WIP! Use a string instead of a state-machine-ey kernel selection mechanism where kernel names have to be predefined. This should allow just dropping new kernels into dir `kernel` without bloating the code in three other places. Is in dire need of a cleanup, function parameter check, edge case check - all the usual testing. In particular, checking these definitions/keywords: * enum cl_kernels * kname * [c]gpu[s]->kernel (and similar) * memory cleanup after strdup()?.. * chosen_kernel * queue_scrypt_kernel * strbuf * initCl	11 years ago
unknown	f7f582732a	Fixed bufsize type.	11 years ago
Noel Maersk	c6a27709f8	core: use global algorithm structure instead of opt_nfactor. Also squashed: config: add log messages to set_algo() and set_nfactor(). algorithm: use set_algorithm_nfactor() when setting default nfactor in set_algorithm(). Otherwise algorithm->n defaults to 0. P.S. Did I already mention how this could have been C++?..	11 years ago
Noel Maersk	c2c8231b9e	kernel: zuikkis supports all worksizes. Closes https://github.com/veox/sgminer/issues/130	11 years ago
Noel Maersk	e18bcc2582	kernel: use N-factor table instead of passing parameter N directly.	11 years ago
Noel Maersk	3afaaf1bfa	ocl: rename nfactor to N where appropriate. N = 2^nfactor, so `nfactor` was a bad name choice here.	11 years ago
Noel Maersk	4b3b2ef5a6	ocl: use 'nf' instead of 'n' in compiled kernel binary name. It is used as a factor number here (e.g. 10, not 1024).	11 years ago
Noel Maersk	5b42d38f33	ocl/misc: spacing.	11 years ago
Noel Maersk	7217da3078	ocl: vectors are hard-set to 1, add appropriate "optimisation".	11 years ago
Noel Maersk	ab9fcb1a14	ocl: use same type convention for nfactor (`cl_uint` instead of `int`).	11 years ago
Teemu Suikki	73bb1504e9	Scrypt-nfactor support! Added new configuration parameter "nfactor", which defaults to 10 (normal scrypt). Use 11 for vertcoin. Kernels modified accordingly.	11 years ago
Brandon Tuomela	bda1070259	kernel: add psw kernel.	11 years ago

Noel Maersk	e8978db55f	kernel: slight refactor, add warnings about new kernels, and known limitations of zuikkis. Limitations of alexkar* kernels are not known to me. Closes https://github.com/veox/sgminer/issues/28	11 years ago
Noel Maersk	5f326d64f5	kernel: allow choosing Alexey Karimov's kernels. Am I the only one who gets a segfault?..	11 years ago
Noel Maersk	7950c10374	kernel: integrate Zuikkis' kernel, selectable with `--kernel=zuikkis`. Kernel ckolivas is still the default. Needs documentation, too. https://github.com/veox/sgminer/issues/4	11 years ago
Noel Maersk	9d1db95a28	misc: move scrypt130511.cl kernel file to kernel/ckolivas.cl Prepare for more kernels. :) Get rid of the kernel date, since this fudges up commit history. Named after Con Kolivas, the most recent committer.	11 years ago
Martin Danielsen	7aeae40af2	EXPERIMENTAL: A new way of setting intensity; introducing xintensity! All of this is credited to ArGee of RGMiner, he did the initial ground work for this setting. This new setting allows for a much finer grained intensity setting and also opens up for dual gpu threads on devices not previously able to. Note: make sure to use lower thread-concurrency values when you increase cpu threads. Intensity is currently used to spawn GPU threads as a simple 2^value setting. I:13 = 8192 threads I:15 = 32768 threads I:17 = 131072 threads I:18 = 262144 threads I:19 = 524288 threads I:20 = 1048576 threads Notice how the higher settings increase thread count tremendously. Now enter the xintensity setting (Yes, I am a genius with my naming convention!). It is simply a shader multiplier, obviously based on the amount of shaders you got on a card, this should allow the same value to scale with different card models. 6970 with 1536 shaders: xI:64 = 98304 threads R9 280X with 2048 shaders: xI:64 = 131072 threads R9 290 with 2560 shaders: xI:64 = 180224 threads R9 290X with 2816 shaders: xI:64 = 163840 threads 6970 with 1536 shaders: xI:300 = 460800 threads R9 280X with 2048 shaders: xI:300 = 614400 threads R9 290 with 2560 shaders: xI:300 = 768000 threads R9 290X with 2816 shaders: xI:300 = 844800 threads It's now much easier to control thread intensity and it potentially allows for a uniform way of setting the intensity on your system. I'm very interested in constructive feedback, as I do not have access to a lot of different card models. This change has been tested on 6970, R9 290, R9 290X - all with equal or a little better speeds than regular intensity setting after a little tuning, but your mileage may vary. Don't fret it, if this doesn't work for you, the regular intensity setting is still available. Conflicts: driver-opencl.c sgminer.c	11 years ago

Noel Maersk	d0070c0424	HARD RESET to: Remove Bitcoin detection code. I'm pretty sure no one was working on this but me. The code was unusable (gave 100% hardware errors) due to me not testing it sufficiently. I hope this will not happen again. ADL doesn't work for some reason, too.	11 years ago
