Title: Amd 13.4 and phatk kernel on poclbm possible workarround Post by: Khertan on May 31, 2013, 01:03:18 PM Hi,
So start with the beggining : Using debian amd 13.4 driver give me errors while using poclbm miner : Failed verification check hardware. I use the following configuration : poclbm.py --cutoff-temp=72 -v -w 256 And a 5770 Vapor-x As i can't downgrade amd driver for various reason, i take a look at the problem. It s look like that come from some modifications made by amd in the opencl drivers. The problem look like located line 30 of the phatk kernel : Code: 39 #ifdef BFI_INT remove that code and replace it by : Code: #define Ch(x, y, z) bitselect(z, y, x) The amd_bytealign seems have changes in recent driver but can't found documentations ... That s works for my 5770 with driver version 13.4-2 Title: Re: Amd 13.4 and phatk kernel on poclbm possible workarround Post by: LudwigDG on June 19, 2013, 08:23:59 AM Greetings, thank you for your research to see how this can be helped.
I have the same problem, but I don't fully understand how I can solve this problem because I can't find that code to change it. Where is os located? How can I get it open, what program? I would really appreciate your help. Cause I'm stuck with this problem.

Personnaly i use the git source ... So the phatk kernel is located in ./phatk.cl. And you can edit it with any text editor, as it opencl source that is compiled at runtime. Edit it, then launch poclbm ... Or use the one that i ve edited : http://khertan.net/datas/downloads/Others/phatk.cl (http://khertan.net/datas/downloads/Others/phatk.cl) Title: Re: Amd 13.4 and phatk kernel on poclbm possible workarround Post by: LudwigDG on June 19, 2013, 07:34:19 PM Thank you so much.
Now everything is working again and I'm mining 8% faster than with the older versions. Title: Re: Amd 13.4 and phatk kernel on poclbm possible workarround Post by: patoberli on September 27, 2013, 06:17:13 PM Thanks, this fixed it for me!
System Win8 x64, GUIminer and a radeon mobility 5870 with latest 13.10 beta drivers. Title: Re: Amd 13.4 and phatk kernel on poclbm possible workarround Post by: crazyates on September 27, 2013, 06:46:38 PM Wait, people are still GPU mining BTC? Wowzers.
