Subject: Re: [PATCH v5 4/4] arm64: Kconfig: Enable HOTPLUG_SMT
Date: Tue, 27 Aug 2024 17:40:44 +0200 [thread overview]
Message-ID: <4024c9be-aae9-4248-ab73-813c3c5d790b@arm.com> (raw)
In-Reply-To: <20240806085320.63514-5-yangyicong@huawei.com>
Hello Yicong,
Is it necessary to have an explicit dependency over SMP for arm64 ? Cf.
commit 4b3dc9679cf7 ("arm64: force CONFIG_SMP=y and remove redundant #ifdefs")
Regards,
Pierre
