GIC Interrupt Processing in Linux Interrupt Subsystem

WebHere is a description of my processors: - A53_0 (Core 0) to get interrupts from TTC for Ethernet - A53_1 (Core 1) to get interrupts from Watchdog Timer, and a few other custom PL interrupts - A53_2 (Core 2) to get interrupts from custom PL IP For startup, Core 1 comes up first, sets up shared memory space, and then brings up Core 0 and Core 2. There is a register/bit in the GIC that can force an interrupt. Try to manually force it every 100 (or whatever is appropriate) iterations in your main loop. You have to set a MCR to tell the CPU where your vector table is. As well, the CPU has an interrupt mask as well as the registers in the GIC. WebOct 4, 2024 · The GIC supports trustzone. You need to put your RTOS in the secure world and Linux in the normal world. There are some settings like FIQ mode that need to be set in the secure world, so you need an smc for linux to set this. The last time I used Linux 3.xx time frame, this was in the Linux GIC drivers. – artless noise Dec 24, 2024 at 18:19 literacy area ideas
