After upgrading the kernel to latest 4.14.x kernel, there are new kconfig options that need users to select in install-kata-kernel.sh. the prompt will block the script. We update this config file to give user a good defined default config. The new kconfig options are about, “Meltdown” and “Spectre”. So I selected them to yes by default in this config file: CONFIG_ARM64_ERRATUM_1024718=y CONFIG_QCOM_FALKOR_ERRATUM_E1041=y CONFIG_UNMAP_KERNEL_AT_EL0=y CONFIG_HARDEN_BRANCH_PREDICTOR=y CONFIG_ARM64_SSBD=y Fixed #106 Signed-off-by: Wei Chen <wei.chen@arm.com> Signed-off-by: Penny Zheng <penny.zheng@arm.com>
Build Kata Containers Kernel
This document explains the steps to build a compatible kernel with Kata Containers. To do this use build-kernel.sh, this script automates the process to build a kernel for Kata Containers.
Setup kernel source code
./build-kernel.sh setup
The script ./build-kernel.sh tries to apply the patches from
${GOPATH}/src/github.com/kata-containers/packaging/kernel/patches/ when it
sets up a kernel. If you want to add a source modification, add a patch on this
directory.
The script also adds a kernel config file from
${GOPATH}/src/github.com/kata-containers/packaging/kernel/configs/ to .config
in the kernel source code. You can modify it as needed.
Build the kernel
After the kernel source code is ready it is possible to build the kernel.
./build-kernel.sh build
Install the Kernel in the default path for Kata
Kata Containers uses some default path to search a kernel to boot. To install on this path, the following command will install it to the default Kata containers path.
./build-kernel.sh install
