Wolf's OpenCL XMR Miner for AMD GPUs

If you get an error about clCreateBuffer, lower your rawintensity. See the example config xmr.conf for details.

Generally, you want to raise rawintensity as high as it will go without error - but remember, 2MiB of GPU RAM is needed for every work-item.

The GPU fan, powertune, and clock setting options are accepted, as the configuration routine was ripped from my own full-custom miner, but they do nothing.

hyc's additions (Linux only)

Use a GPU index of -1 to run on the CPU. The only other config item needed is "threads", but rawintensity and worksize must still be set to a non-zero value.

As with the original CPU miner, you can gain a performance boost by configuring huge pages. Check current setting with sysctl vm.nr_hugepages then set it to at least 3 times the total number of threads you're using, as root.

sudo sysctl -w vm.nr_hugepages=num

Also, it can run faster as root, which allows it to use mlock.
