/sys/debug/ fw_profile/ipc_type: permission denied #1171
Description
Activity
I think you didn't notice because you run sof-test as root but that's not how it's usually tested.
You can borrow any CI device to test and fix, no need to change the configuration of yours.
I am a bit confused here. The two files have the same permissions and use the same cat command.

/sys/kernel/debug is a different filesystem / mount point.
