By the way, I'm having great trouble justifying the FPGA support in cgminer. It's taking me a fair amount of time vetting all the code that comes in, dealing with the drama of different coders not getting on, and that I don't have an FPGA so the code does not benefit me, nor am I earning anything off supporting FPGAs. So once again I find myself in a quandary about whether I should even be supporting them at all or not (like CPU mining, but for precisely the opposite reason!). So unless this gets easier, and it looks like it will only get harder, there is a very real possibility that someone like Luke-jr will fork the FPGA code into a separate project (he has even suggested he will) and I'll stop supporting it. I'm just giving advance warning here to people about this issue. I know it's just me whining, and harsh, but the fact is that the effort has to come from somewhere, and I do not have infinite time on my hands.

I paid luke 5BTC for the share log solution:

http://blockchain.info/tx/7732db071b843e378b458b447c4962b0ffb22d638da77096238cd266fc847eef

ckolivas, if you don't like the share log idea and want to do something else officially, I'm willing to still pay you the original 15 BTC since I should have anticipated the fact that someone else might have created a solution in the short time between when I posted the request and when you saw the bounty and decided to do something else.

Just let me know what you prefer.
It's only money and you've already given some of it to luke who did the work. Why should I make you pay more than you originally offered? Luke's code is fine, but if you want me to include it, it'll have to be a proper pull request and fully documented as well since he'll get even more bounty according to your original offer if I include the code.

Gotta be quick to get the quick bucks it seems. I'll go back to the boring slow grind work instead Tongue
I commented on a couple of minor issues with his code, he modified it, and I've included it in my git tree now.

Awesome, thanks.

The remaining two bounty payments have been sent:

To Luke: http://blockchain.info/tx/ba031cdf4efdaf4a7f6bce52442539c6a415b5c612f194c04a4a4971cfdebb9b
To Ckolivas: http://blockchain.info/tx/a11d526aa66121ed4b0bb5cf828f2ab223e83a34471dbf6020e664dc219b52b5

If we can get you FPGAs, would you be willing to support those in cgminer?

umm have you guys seen any issues with memory usage with cgminer under win 7 x64?
It seems like a memory leak. It doesn't go above 400mb in peak working set(taskmgr) yet slowly all of my ram is filled and then the inevitable happens. Everything goes to hell. Quitting the program doesn't free the used ram. Only reboot helps.
I have 2x 5970 2x 5870 with 11.12 catalyst + 2.5 sdk.

If you think my comments have benefitted you it would be nice to hear thanks Smiley

But of course. It would be a self-fulfilling donation then which is better than just giving me the equivalent amount of BTC, as was the 7970 donation and much better cgminer support for GCN cards as a result. Continuing to support would be guaranteed if I owned one of the devices.

Ok, I'm confused.  I just updated two separate machines:

git pull
make clean
ATISTREAMSDKROOT="/opt/AMD-APP-SDK-v2.4-lnx32/"  CFLAGS="-O2 -Wall -march=native" ./configure --enable-bitforce --bindir="/opt/miners/cgminer" --prefix="/opt/miners/cgminer"
make

Both machines are basically the same... here's what I get as a resulting binary:

Machine 1:

./cgminer --version
cgminer 2.3.4

Machine 2:
./cgminer --version
cgminer 2.3.3


Machine 1 fetch head:

effdbaf2062e54ba220974a9ab364a4f94088d9e        not-for-merge   branch 'kernel' of https://github.com/ckolivas/cgminer
0e916802ce80465282638728cede0d62fd2d723e                branch 'master' of https://github.com/ckolivas/cgminer

Machine 2 fetch head:

effdbaf2062e54ba220974a9ab364a4f94088d9e        not-for-merge   branch 'kernel' of https://github.com/ckolivas/cgminer
0e916802ce80465282638728cede0d62fd2d723e                branch 'master' of https://github.com/ckolivas/cgminer


I am confused...  Anyone have any idea what's up?

You "forgot" to re-run autogen. For some reason, cgminer's Makefile doesn't do it.

The question that really needs to be asked is: will this change your current policy of all Icarus driver changes going through Kano (which allows him to continue breaking it, and neglects all the fixes and optimizations I've made), and instead consider merges based on their actual code quality?

Silly me!  I don't normally run autogen when recompiling.  Guess I'll make that habit for cgminer. 

Thanks!

I agree with your views.

I don't have any FPGA and don't plan on ever having one.

Maybe start FPGAminer project Tongue but let us concentrate on GPUs for now because a majority of miners are using them right now.

FPGA is just a minority ...

Minority or not, I like cgminer so much I'm supporting ztex there myself. There has been some extra work for ckolivas as I adapt to cgminer's coding style but it is more or less easy to keep most changes separate fromt he main cgminer code. I do think ckolivas' time is best spent making cgminer even better and more stable rather than implementing fpgas there, seeing he is very good in the gpu support, as it is in his personal interest anyway Smiley

I think cgminer as a gpu + fpga miner is unbeatable, and I'll do all I can to keep it that way. We can always fork it, but I think as FPGAs become more mainstream it is good for the community as a whole if it stays in the same place.

Well, you could withdraw support from cgminer... but I think the better course of action is to modularize all of the processor types and abstract them from the cgminer core.

You can then concentrate on developing the cgminer core and the gpu module and others can concentrate on the FPGA, ASIC, etc... modules.  Tear all of the built in code that's in there so far and put it in a separate module for each type of device.  Then call those modules from cgminer to do their thing, have them return the proper data and let the cgminer core handle sending the results/requesting the getworks from the server and displaying the results to the screen.

Yes, that's what I did when I added FPGA support originally. The code is still in the same tree, however.

Regarding ztex support, is dynamic frequency scaling supported (like with BTCMiner)?

Yes.
And the pull request I have in at the moment adds Ztex (and the frequency) to the API PGA output
(frequency on the end of course)

Regarding ztex support, is dynamic frequency scaling supported (like with BTCMiner)?

Yes. There are a few things missing still:

- support for quad boards (1.15y)
- suspend
- high speed bitstream upload
- hotplug
- firmware upload (to support hot upgrade and the new bogus firmware feature)
- Support for the latest firmware (120417, bitstream 15d4) - This is already done but waiting on inclusion on the main repository

All of the above will be addressed as time permits. You can use the latest firmware if you compile cgminer yourself, grab it here -> https://github.com/nelisky/cgminer/tree/ztex-120417

There is a lot more I want to do but I've been mining with ztex 1.15x boards on cgminer for roughly one month now and it works great Smiley
