README.irq : Shuchen Kate Feng , Sept. 2, 2007 As per implementation in shared PPC code, the BSPirqPrioTable[96] listed in irq_init.c is where the software developers can change the levels of priority for all the interrupts based on the need of their applications. The IRQs can be eanbled dynamically via the BSP_enable_pic_irq(), or disbaled dynamically via the BSP_disable_pic_irq(). Support for run-time priority setup could be added easily, but there is no action taken yet due to concerns over computer security at VME CPU level. The software developers are forbidden to setup picIsrTable[], as it is a powerful engine for the BSP to find the pending highest priority IRQ at run time. It ensures the fastest/faster interrupt service to the highest/higher priority IRQ, if pending.
