Kernel feature support
|
Ben Hutchings <ben.hutchings@...>
We've previously agreed that not all kernel features (drivers,
filesystems, network protocols, etc.) can be supported in an SLTS branch. I'd like to start working out what the supported features should be for the 4.4 branch. Are members able to share their kernel .config files, showing which features are enabled? Or would you prefer to specify your needs at a slightly higher level?

Please take some time to provide feedback. Best Regards -- Agustin Benito Bethencourt Principal Consultant - FOSS at Codethink agustin.benito@...

Hello Agustin, Ben,
Sorry for the slow response to your query. From: cip-dev-bounces@... [mailto:cip-dev-From an SoC vendor point of view, ideally we'd like the interfaces provided by the reference platform to be included. As support for our CIP reference platform is not yet mainlined, I can't provide the exact .config yet. However it will likely be very similar to shmobile_defconfig [1]. Of course, narrowing down configurations supported by the CIP Kernel should probably be lead more by the end use-cases, but hopefully this is a start. [1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm/configs/shmobile_defconfig Kind regards, Chris

Hello Agustin and Ben,
From: cip-dev-bounces@... [mailto:cip-dev-bounces@...] On Behalf Of Agustin BenitoI attached a defconfig for one of our products running on 4.4.12. This config is based on omap2plus_defconfig, and a diff from omap2plus_defconfig is also attached. Currently, each config item has not been prioritized yet, and it may contain non-important items. Please treat our defconfig as a reference at this point. Best regards, Hidehiro Kawai Hitachi, Ltd. Research & Development Group

Hi,Sorry for the late reply! Please find attached an x86 kernel configuration from early product development using kernel 4.4. This product uses nearly-COTS server hardware due to needed computation power, but also comes with nice embedded requirements like longterm maintenance - and as a special need, real-time support, so we use Linux-Ipipe/Xenomai here. This means two things: * many included drivers (especially in net and storage) are only activated "to be prepared" for future hw replacements * Feel free to either include Xenomai on your list as a used "kernel feature" or to ignore the related options. So same as with the config from Hidehiro Kawai: please let me know if you need prioritized list of drivers or other features! -- Kind regards, Gernot Hillier Siemens AG, Corporate Competence Center Embedded Linux

One is attached already, derived from github.com/siemens/meta-iot2000. Xenomai is not in CIP scope right now (though Siemens would welcome anyone interested in collaborating on it). In general, anything in a config not part of upstream is filtered out "automatically", I would say. There are switches for out-of-tree features in the iot2000 config as well (we are still in the process of upstreaming).

Hi Ben,

-----Original Message-----Please find attached to this e-mail four kernel v4.4 configurations for different architectures and platforms. Some of these kernels contain vendor patches and the PREEMPT RT patch. Also, please note that they were created with 'make ARCH=xxx savedefconfig'. Or would you prefer to specify your needs at aI prepared a list of kernel config options that I consider the most important among the configs we are using. You can find them in the file config-cip (included in the attached zip file) which is reproduced below: General setup CONFIG_POSIX_MQUEUE CONFIG_HZ_PERIODIC CONFIG_HIGH_RES_TIMERS CONFIG_IKCONFIG CONFIG_IKCONFIG_PROC CONFIG_CGROUPS CONFIG_CPUSETS CONFIG_NAMESPACES CONFIG_SCHED_AUTOGROUP CONFIG_BLK_DEV_INITRD CONFIG_RD_GZIP CONFIG_SHMEM CONFIG_SYSCTL_SYSCALL CONFIG_KPROBES Processor type and features CONFIG_SMP CONFIG_EFI CONFIG_HOTPLUG_CPU CONFIG_CRASH_DUMP System type CONFIG_ARCH_TEGRA CONFIG_ARCH_ZYNQ Filesystems CONFIG_EXT4_FS CONFIG_INOTIFY_USER CONFIG_OVERLAY_FS CONFIG_VFAT_FS CONFIG_PROC_FS CONFIG_SYSFS CONFIG_TMPFS CONFIG_SQUASHFS CONFIG_JFFS2_FS Networking support CONFIG_INET CONFIG_VLAN_8021Q CONFIG_IPV6 Device drivers CONFIG_UIO CONFIG_UIO_PDRV_GENIRQ CONFIG_USB_EHCI_HCD CONFIG_USB_XHCI_HCD CONFIG_USB_STORAGE CONFIG_USB_HID CONFIG_USB_NET_DRIVERS CONFIG_FB CONFIG_TUN CONFIG_DEVTMPFS CONFIG_DEVTMPFS_MOUNT CONFIG_GPIOLIB CONFIG_GPIO_SYSFS CONFIG_GPIOLIB_IRQCHIP CONFIG_BLK_DEV_RAM CONFIG_MTD CONFIG_MTD_BLOCK CONFIG_MTD_NAND CONFIG_I2C CONFIG_SPI CONFIG_MMC CONFIG_MMC_SDHCI CONFIG_INPUT_EVDEV CONFIG_PPS CONFIG_E1000E CONFIG_I40E CONFIG_IGB Kernel hacking CONFIG_FTRACE CONFIG_FUNCTION_TRACER CONFIG_PRINTK_TIME CONFIG_PANIC_ON_OOPS Some of these kernel config options may be out of scope or too broad.

Some are just stripped-down defconfigs, some are 4.1-based (to become 4.4 eventually), but I hope they are useful. Any out-of-tree switch is to be ignored, of course. I hope there will be more configs in the future. E.g., some projects on 4.4 are still running an expanded development feature set.
