--- Comment #53 from MasterCATZ (mastercatz@hotmail.com) --- its been like this since mid kernel 4's, just wish I knew whats locking that file root has no permissions and it seems to activate @ 70 deg , which even if i run the fan 100% will be reached unless I under clock
amdgpupro just turns PC into a paperweight so I don't use that radeon drivers suck for any gaming amdgpu / mesa are what I need to use and its been like this since powerplay was introduced
Ubuntu 18.04, and just upgraded it to 19.10 same issues currently using 5.4.2-050402-generic
GRUB_CMDLINE_LINUX_DEFAULT="amdgpu.ppfeaturemask=0xfffd7fff amdgpu.ppfeaturemask=0xffffffff amdgpu.dc=1 amdgpu.cik_support=1 radeon.cik_support=0"
featuremasks seem to make no difference maybe I should re - add radeon.si_support=0 amdgpu.si_support=1
as in as radeon profile is showing radeonsi is in use ?, but I thought R9 290 were Sea Islands = amdgpu.cik_support=1 ?
