Subject: [PATCH 2/2] arm: multi_v7_defconfig: Enable KSM.
Date: Thu, 14 Jun 2018 17:50:27 -0500 [thread overview]
Message-ID: <1529016629-2948-2-git-send-email-daniel.diaz@linaro.org> (raw)
In-Reply-To: <1529016629-2948-1-git-send-email-daniel.diaz@linaro.org>
As per the documentation, Kernel Samepage Merging (available
since 2.6.32) is a memory-saving de-duplication feature,
enabled by CONFIG_KSM=y and activated via sysfs. More
information can be found here:
https://www.kernel.org/doc/Documentation/vm/ksm.txt
When enabled in the kernel, the default is to not do anything
at all, until it is activated at run-time with:
echo 1 > /sys/kernel/mm/ksm/run
Signed-off-by: Daniel D?az <daniel.diaz@linaro.org>
