remove CONFIG_ANDROID_LOW_MEMORY_KILLER requirement Kernel configuration options should include either CONFIG_ANDROID_LOW_MEMORY_KILLER for in-kernel lowmemorykiller driver to be used or a combination of CONFIG_MEMCG and CONFIG_MEMCG_SWAP if userspace lmkd is preferred. It is not currently possible to express this logical requirement in the config fragment so the CONFIG_ANDROID_LOW_MEMORY_KILLER requirement is simply removed for now. Bug: 71502948 Change-Id: If022e978265465e7de75e23ac90361149398df3b Signed-off-by: Suren Baghdasaryan <surenb@google.com>
The files in these directories are meant to be used as a base for an Android kernel config. All devices must have the options in android-base.cfg configured as specified. If an android-base-ARCH.cfg file exists for the architecture of your device, the options in that file must be configured as specified also.
While not mandatory, the options in android-recommended.cfg enable advanced Android features.
Assuming you already have a minimalist defconfig for your device, a possible way to enable these options would be to use the merge_config.sh script in the kernel tree. From the root of the kernel tree:
ARCH=<arch> scripts/kconfig/merge_config.sh <...>/<device>_defconfig <...>/android-base.cfg <...>/android-base-<arch>.cfg <...>/android-recommended.cfg
This will generate a .config that can then be used to save a new defconfig or compile a new kernel with Android features enabled.
Because there is no tool to consistently generate these config fragments, lets keep them alphabetically sorted instead of random.
