Tom, which Fedora version do you tried and with which kernel?
I am tried several kernels from old 4.19-rc2 to fresh 4.20-rc7 and
every time when I tried run `# cat
/sys/kernel/debug/dri/0/amdgpu_gca_config` I got message that
"Operation not permitted".
I try understand difference with our setups. If you use default kernel
it means that kernel options between our setups are same. Difference
only in hardware and mounted file systems.
P.S. I am also tried ask how to manage ACL in debugfs in
platform-driver-x86 mail list, but no one answer.
