Priority: medium Bug ID: 74190 Assignee: dri-devel@lists.freedesktop.org Summary: scrypt doesn't do anything with bfgminer on CAYMAN Severity: normal Classification: Unclassified OS: Linux (All) Reporter: v10lator@myway.de Hardware: All Status: NEW Version: 10.0 Component: Drivers/Gallium/r600 Product: Mesa
Created attachment 93006 --> https://bugs.freedesktop.org/attachment.cgi?id=93006&action=edit R600_DEBUG=cs bfgminer 2> ~/bfgminer.txt
I have a Radeon HD 6950. When I try to use scrypt with bfgminer (for mining litecoins, for example) bfgminer gives the following output every minute:
[2014-01-29 15:57:34] OCL 0: Idle for more than 60 seconds, declaring SICK! [2014-01-29 15:57:34] OCL 0: Attempting to restart [2014-01-29 15:57:34] Thread 0 still exists, killing it off [2014-01-29 15:57:35] Thread 0 restarted
and the minig speed is 0.00 hashes/second

If you check CPU usage, you should see a thread stuck at 100% - this is apparently it trying to compile the opencl program. I have not tried waiting a long time to see if it does eventually fire up.

Yes, that seems to be it.
But there seems to be a memory leak, too. The thread eats up more and more RAM. Also after each
[2014-02-24 10:00:47] OCL 0: Idle for more than 60 seconds, declaring SICK! [2014-02-24 10:00:47] OCL 0: Attempting to restart [2014-02-24 10:00:47] Thread 0 still exists, killing it off [2014-02-24 10:00:48] Thread 0 restarted
it eats +1 core (so first 100%, then after that 200%, after the next 300% and so on). This repeats till it's killed cause of no more free RAM.
Should I add this information to your bug report?
