Paul Burton 6759657341 MIPS: Allow 24Hz timer frequency ... A boundary exists beyond which the timer frequency becomes high enough that timer interrupts saturate the system and either cause it to slow to a crawl or stop functioning entirely. Where that boundary lies depends upon a number of factors such as the overhead of each interrupt and the overall speed of the CPU, but correlates strongly with the clock frequency at which the CPU runs. When running on emulators during bringup or debug of a CPU that clock frequency is very low, which results in the boundary at which the timer frequency becomes unsustainable being very low. The current minimum of 48Hz pushes against boundary in certain situations in current systems. Allow the kernel to be configured for a 24Hz timer frequency in order to avoid problems on such slow running systems.
