It is not arch-specific because you can read a perf.data file from one architecture on another architecture.
The TSC stuff was planned for Intel PT although it might now be done differently.
Probably you should have CONFIG_X86_TSC and then select that with CONFIG_X86. Later it can be selected with CONFIG_INTEL_PT as well.
