can you make new superb kernel with target=11 for those cards?
I can share this kernel, but everyone can do this.
Best option for Tahiti/Hawaii (R9 280/290) is Catalyst 14.6, for R9 390 - Catalyst 15.12 with ocl from 14.6.
please share that kernel.
win10, driver 15.12, xpmclient9.4.1 with ocl14.6 simple fails to start.
xpmclient start and close after 1 second.
