From: Yousong Zhou Date: Wed, 23 Nov 2016 16:03:41 +0000 (+0800) Subject: target: sunxi: enable kvm support X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=468735c3a2f75f4ae6592608c789d8753f418a84;p=openwrt%2Fstaging%2Fneocturne.git target: sunxi: enable kvm support Unlike x86, kvm for arm has to be built into the kernel. The kernel config was prepared with the following command make kernel_menuconfig CONFIG_TARGET=platform Then enable ARM_LPAE, VIRTUALIZATION, KVM in that order Other config changes are done by the build system. The following text tries to explain some of them, for archive purposes probably... - BUILD_BIN2C. It was dropped probably because the prompt is empty and no other config option selects it. bin2c is a host executable for converting binary content to a piece of c code for inclusion - CRYPTO_DEV_SUN4I_SS. It was dropped because the dependency CRYPTO_HW was not enabled. Setting that aside, packaging it as a loadbable module in lieu of other sunxi specific modules seems more appropriate - PGTABLE_LEVELS. It was changed from 2 to 3 because 3 is the default when ARM_LPAE is enabled - HAVE_KERNEL_GZIP, etc.. These are enabled in generic config - SCHED_INFO, ZLIB_INFLATE. These were dropped probably for the same reason as for BUILD_BIN2C Signed-off-by: Yousong Zhou --- diff --git a/target/linux/sunxi/config-4.4 b/target/linux/sunxi/config-4.4 index b05446c6d2..b0a651a689 100644 --- a/target/linux/sunxi/config-4.4 +++ b/target/linux/sunxi/config-4.4 @@ -2,6 +2,7 @@ CONFIG_ADVISE_SYSCALLS=y #
