Subject: [PATCH] arm64: Kconfig: Increase NR_CPUS default to 512
Date: Sat, 9 Jan 2021 21:36:15 -0800 [thread overview]
Message-ID: <20210110053615.3594358-1-vanshikonda@os.amperecomputing.com> (raw)
From: Vanshidhar Konda <vanshikonda@os.amperecomputing.com>
Increase the default value of NR_CPUS to 512 from 256. This will
enable the defconfig kernel to support platforms that have upto
512 cores.
