I agree - integration registers should not be enabled by default.
Do we want this turned on by default? According to the description it's a bit dangerous and it's exposed via sysfs rather than debugfs.
Should I disable just CONFIG_CORESIGHT_CTI_INTEGRATION_REGS or CONFIG_CORESIGHT_CTI as well? There are other writable registers exposed via sysfs outside of these two options, so I wanted to check if it's just the integration registers that are the issue.
