[PATCH 5/8] drivers/perf: hisi: Extend the field of tt_core
From: Yushan Wang
Date: Tue Jul 29 2025 - 11:40:13 EST
From: Yicong Yang <yangyicong@xxxxxxxxxxxxx>
Currently the tt_core's using config1's bit [7, 0] and can not be
extended. For some platforms there's more the 8 CPUs sharing the
L3 cache. So make tt_core use config2's bit [15, 0] and the remaining
bits in config2 is reserved for extension.
