The SRR Module facilitates communication between software components through synchronous message passing and asynchronous event notification using proxies.
The SRR Module is an open-source project that is being maintained by Cogent and distributed under the GNU General Public License (GPL). It is a powerful tool that provides synchronous message passing, asynchronous event notification (proxies), and user-space interrupt handling for the Linux operating system.
One of the most notable features of the SRR Module is its implementation of synchronous message passing, a fast, flexible, and robust IPC mechanism that is particularly useful for building systems composed of multiple co-operating processes. The implementation of the SRR Module was inspired by the QNX operating system and allows one process or thread to send a message to another process or thread, with the first process waiting until the second process replies. This message-passing feature has been used for over a decade as a reliable way to create flexible, modular program architectures.
In addition to the basic send-receive-reply mechanism, the SRR Module also includes other functions such as proxies (queued asynchronous events), timed delivery of proxies and signals, triggering of proxies between tasks, and user-space interrupt handling. Furthermore, the addition of thread support allows proxies and synchronous messages to be used as inter-thread synchronization and communication facilities. Proxies can also be used to solve several common race conditions associated with signals.
The SRR Module includes an API library written in C and a QNX 4 compatibility layer. It is incredibly stable and extremely fast, achieving approximately 80% of QNX 4's performance on the same hardware.
The latest release of the SRR Module features several notable improvements, including a change to work handlers in keeping with version 2.6.20 of the Linux kernel, fixes for module compilation, support for messages larger than 3 MBytes, workarounds for udev issues, fixes for potential timer IRQ race conditions, replacement of spinlocks with mutexes where swapping is allowed, addition of relay functions, implementation of clock_getres(), removal of unnecessary OOPS messages, and fixing of the Sendmx() return value.
Overall, the SRR Module is a reliable and efficient tool that offers a wide range of features and capabilities for software developers using the Linux operating system.
