KBUS is a lightweight, Linux kernel mediated, message system, particularly intended for use in embedded environments. It is meant to be simple to use and understand. It is designed to provide predictable message delivery, deterministic message ordering, and a guaranteed reply for each request. It is especially aimed at situations where existing solutions, such as DBUS, cannot be used, typically because of system constraints. We have various customers using KBUS in real life, and believe it to be useful. I had a showcase table for KBUS at the ELCE in Cambridge, October last year, and there seemed to be interest. I am hoping to get a response from this list before attempting to send to the kernel list, since I believe this list should contain people who might be most interested in using it. The KBUS project home page is at http://kbus-messaging.org/, from which there are various useful links. There is a working repository with Linux 2.6.37 patched for KBUS, available via: git pull git://github.com/crazyscot/linux-2.6-kbus.git kbus-2.6.37 This is a resubmission of the original RFC to the Linux-Embedded list, having: a) changed to use __u32 instead of uint32_t and b) changed to use kernel messaging mechanisms (also removing some messaging that should not be needed). These in response to the suggestion of Sam Ravnborg c) split into multiple in-line patches, as is normal practice, and as requested by Grant Likely Tibs (5): Documentation for KBUS External header file for KBUS Kconfig files and Makefile for KBUS Internal header file for KBUS KBUS itself, the main source file Documentation/Kbus.txt | 1222 +++++++++++ include/linux/kbus_defns.h | 666 ++++++ init/Kconfig | 3 + ipc/Kconfig | 99 + ipc/Makefile | 5 + ipc/kbus.c | 4927 ++++++++++++++++++++++++++++++++++++++++++++ ipc/kbus_internal.h | 709 +++++++ 7 files changed, 7631 insertions(+), 0 deletions(-) create mode 100644 Documentation/Kbus.txt create mode 100644 include/linux/kbus_defns.h create mode 100644 ipc/Kconfig create mode 100644 ipc/kbus.c create mode 100644 ipc/kbus_internal.h -- To unsubscribe from this list: send the line "unsubscribe linux-embedded" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
