Subject: [PATCH v2 7/7] MIPS: Limit MIPS_MT_SMP support by ISA reversion
Date: Fri, 14 Apr 2023 09:07:01 +0100 [thread overview]
Message-ID: <20230414080701.15503-8-jiaxun.yang@flygoat.com> (raw)
In-Reply-To: <20230414080701.15503-1-jiaxun.yang@flygoat.com>
MIPS MT ASE is only available on ISA between Release 1 and Release 5.
Add ISA level dependency to Kconfig to fix build.
