Subject: [PATCH 0/2] CPUCFG emulation future-proofing & HWCAP addition
Date: Sat, 30 May 2020 01:09:58 +0800 [thread overview]
Message-ID: <20200529171000.8905-1-git@xen0n.name> (raw)
This patch series future-proofs the CPUCFG emulation, in light of
possibility of new Loongson cores still lacking native CPUCFG.
Also an HWCAP flag bit is allocated and exposed for userspace's probing
convenience, per the earlier plan shared on the mailing list.
WANG Xuerui (2):
MIPS: Loongson64: Guard against future cores without CPUCFG
MIPS: Expose Loongson CPUCFG availability via HWCAP
