My initial intention was to add IPC (required by ALSA), HDMI audio and evdev. As you can imagine, the goal was to play supertuxkart. The rest of the configs got added by Buildroot, because of the systemd presence: $ cat linux/linux.mk [..] $(if $(BR2_PACKAGE_SYSTEMD), $(call KCONFIG_ENABLE_OPT,CONFIG_CGROUPS,$(@D)/.config) $(call KCONFIG_ENABLE_OPT,CONFIG_INOTIFY_USER,$(@D)/.config) $(call KCONFIG_ENABLE_OPT,CONFIG_FHANDLE,$(@D)/.config) $(call KCONFIG_ENABLE_OPT,CONFIG_AUTOFS4_FS,$(@D)/.config) $(call KCONFIG_ENABLE_OPT,CONFIG_TMPFS_POSIX_ACL,$(@D)/.config) $(call KCONFIG_ENABLE_OPT,CONFIG_TMPFS_POSIX_XATTR,$(@D)/.config)) Same goes for devtmpfs, but that's a different matter. I suppose I was originally working with BR2_ROOTFS_DEVICE_CREATION_STATIC=y and so carried the options (not needed with systemd of course). They options got here because I manually added the new options and updated the config from a defconfig using savedefconfig. Anyway: I don't care at all about them, I just want audio and evdev :-) Regarding using systemd, I'll reply to the other patch. >> >> The options are quite common and make the system more useful. >> >> Signed-off-by: Ezequiel Garcia <ezequiel@vanguardiasur.com.ar> >> --- >> board/minnowboard-max/linux.config | 17 +++++++++++++++++ >> 1 file changed, 17 insertions(+) >> >> diff --git a/board/minnowboard-max/linux.config >> b/board/minnowboard-max/linux.config >> index abb7fdce9861..f80170b9b81d 100644 >> --- a/board/minnowboard-max/linux.config >> +++ b/board/minnowboard-max/linux.config >> @@ -1,4 +1,8 @@ >> +CONFIG_SYSVIPC=y >> +CONFIG_POSIX_MQUEUE=y >> +CONFIG_FHANDLE=y >> CONFIG_NO_HZ=y >> +CONFIG_CGROUPS=y >> CONFIG_SMP=y >> CONFIG_X86_INTEL_LPSS=y >> CONFIG_MATOM=y >> @@ -13,12 +17,15 @@ CONFIG_NET=y >> CONFIG_PACKET=y >> CONFIG_UNIX=y >> CONFIG_INET=y >> +CONFIG_DEVTMPFS=y >> +CONFIG_DEVTMPFS_MOUNT=y > > > This is added automatically by Buildroot.

This commit enables support for: * HDMI audio * Support for user-provided EDID firmware (useful to workaround broken monitors) * Evdev interface * System V IPC (required by ALSA) * POSIX message queue * fhandle syscall * cgroups The options are quite common and make the system more useful.
