Using the CSL to complement OS dispatcher in handling Cascaded Interrupts
This application report discusses how CSL's INTC module could be used to share the task of dispatching interrupts with the OS, in scenarios where the OS's interrupt dispatcher does not comprehend cascaded interrupts.
The solution involves having the CSL dispatch the cascaded interrupts alone, while completely leaving the job of dispatching primary CPU interrupts to the OS. We also discuss an example application - of handling Cascading Interrupts in DSP/BIOS on the OMAP5912 platform.
