Add amdapp-sdk, amdadl-sdk and cgminer

[offlinehacker]

• AMD Accelerated Parallel Processing (APP) SDK, with OpenCL 1.2 support.
• API to access display driver functionality for ATI graphics cards
• CPU/GPU miner in c for bitcoin

[domenkozar]

license and platforms come from stdenv.lib.platforms and stdenv.lib.licenses

[offlinehacker]

Tnx, will fix that :)

[offlinehacker]

Licenses are now updated, but for platforms i can't use any entry from stdenv.lib.platforms.

[offlinehacker]

Goal achived, cgminer now working :)

[domenkozar]

Looks ok to me

[offlinehacker]

Wait, do not merge yet, it worked on debian using nix, but have to fix it for nixos ;)

[offlinehacker]

This is now ready to be pulled in. Still some things needs to be fixed in future:

• Test x86 support, before we can do that, ati_unfree drivers must be x86 supported, currently are not
• Fix reaper to compile code located in store, not from current folder(needs fixing reaper)
• Test with nvidia, to do that i need nvidia graphic card

Note: Please first merge #462 this one takes ATI driver patches from there

[domenkozar]

Could you rebase so this can be merged?

[offlinehacker]

This should be it. Once again #462 is included here.

[domenkozar]

this needs to be removed?

[offlinehacker]

Tnx, fixed ;)

[domenkozar]

How do I test it?

[offlinehacker]

Hum for cgminer just nix-env -iA your_repo_name.cgminer, this will also compile amdappsdk and amdadlsdk. For ati drivers i don't know.

[offlinehacker]

This works for me without any problems, for quite some time. @iElectric what's up with testing, any progress? If necessary i can test it from clean install once again, i have some ATI cards lying around.

[domenkozar]

Still needs to be tested :/ I'll try asap

[offlinehacker]

Okay, if you will try mining for real take a look at https://github.com/offlinehacker/miner.litecoin.si/blob/master/miner.nix (at the end of the file), because you have to export some environment variables.

More precisely:

system.activationScripts.drifix = ''
    # Create the required /usr/lib/dri/fglrx_dri.so;
    mkdir -p /usr/lib/dri
    ln -fs /run/opengl-driver/lib/fglrx_dri.so /usr/lib/dri/fglrx_dri.so
  '';

shellInit = ''
  export DISPLAY=:0
  export GPU_MAX_ALLOC_PERCENT=100
  export GPU_USE_SYNC_OBJECTS=1
'';

etc.opencl = {
  source = "${pkgs.amdappsdk}/etc/OpenCL";
  target = "OpenCL";
};

[offlinehacker]

Just rebased once again

[garbas]

are .topdeps and .topmsg files really needed?

[offlinehacker]

Well no, they are reminder from TopGit from MarcWeber commits and must be
removed by merge. I was not using topgit so it was not updated
automatically.

[domenkozar]

Can you remove .topdeps and .topmsg and ati related stuff and force push new changes?

[offlinehacker]

Okay, i have just done that.

[offlinehacker]

I am closing this of honor of #638 pull request, which is updated and rewritten version of this one.
