H A D | mx_pic.c | 10df8ff1 Sun Feb 17 06:38:58 CST 2013 Max Filippov <jcmvbkbc@gmail.com> target/xtensa: add MX interrupt controller MX interrupt controller is a collection of the following devices accessible through the external registers interface: - interrupt distributor can route each external IRQ line to the corresponding external IRQ pin of selected subset of connected xtensa cores. It has per-CPU and per-IRQ enable signals and per-IRQ software assert signals; - IPI controller has 16 per-CPU IPI signals that may be routed to a combination of 3 designated external IRQ pins of connected xtensa cores; - cache coherecy register controls core L1 cache participation in the SMP cluster cache coherency protocol; - runstall register lets BSP core stall and unstall AP cores.
