Hi, The attached patch fixes a bug in the AMD powernow driver, the abs() macro was defined in a way that may lead to unexpected results due to the macro argument expansion vs operator precedence:
----------
#define abs(x) ( x < 0 ? -x : x )
[...]
while (abs(vco_fid - vco_cfid) > 2) {
----------
Cheers,
