To well support the real-time requirement from applications, we enhance the real-time ability in Linux kernel through two new kernel mechanisms. Firstly, we present a new microsecond-level timer mechanism based on UTIME provided by Kurt-Linux, but different from it. The new timing implementation provides more flexible mechanism to support the different-grained timing requirement, as well as more flexible and preferential management of microsecond-level timers. Secondly, we present a new interrupt handler to reduce the kernel delay, which makes it possible scheduling interrupt handler with other processes under the system scheduler. Therefore, making interrupt routine under control is achieved. The experiments show that the improvements are distinct and significant. |
