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 :
39 #ifdef BFI_INT
40 #define Ch(x, y, z) amd_bytealign(x, y, z)
41 #else
42 #define Ch(x, y, z) bitselect(z, y, x)
43 #endif
remove that code and replace it by :
#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
