What is the right forum to discuss the HSA specific questions? Specifically, I want to know whether HSAFoundation/Linux-HSA-Drivers-And-Images-AMD · GitHub will work with catalyst driver. I tried the previous version on Ubuntu 13.10 and I was not able to install catalyst 14.4 when I had HSA kernel installed.
Unfortunately, the HSA Linux kernel driver works only with the open-source radeon driver that comes with the Linux kernel.
If you would like to run HSA on Linux, than you must also use radeon open source driver.
In fact, you should remove the installation of Catalyst because it blacklists the radeon driver from loading (look at files under /etc/modprobe.d/)
