From: Yicong Yang <yangyicong@hisilicon.com> driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC1F9Z CVE: NA ---------------------------------------------------------------------- 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.
