            Bug ID: 96934
           Summary: Mining Ethereum orders of magnitude slower than on
                    proprietary drivers.
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: lvella@gmail.com
        QA Contact: dri-devel@lists.freedesktop.org

By enabling a libclc extension on ethminer OpenCL code, I managed to run it
using Ubuntu 16.04 and Oibaf's PPA. The code has been merged into
https://github.com/ethereum/libethereum and you can benchmark it for yourse=
lf.

Using a Radeon r9 280X, I ran the following command:

$ ethminer -G -F
mine.weipool.org:5555/0x7079a42c78d28ce9216c290d1bbc61e7b12d54a3/0.5

and got in output, among other things:

...

This reported rash rate is about 3% of the rate my GPU is supposed to deliv=
er
(it should be in the order of 22 MH/s).=20

By the way, that command will mine on the public pool WeiPool and direct the
earnings to my address 0x7079a42c78d28ce9216c290d1bbc61e7b12d54a3. If you w=
ant
to try and don't send me money, change that number to you Ethereum or Bitco=
in
address. Instructions in mine.weipool.org.
