The GIC-ITS MSI implementation provides an advantage over internal MSI implementation using Locality-specific Peripheral Interrupts (LPI) that would allow MSIs to be targeted for each CPU core. This series has been tested on SM8450 based dev board that works using an out-of-tree dts where the MSIs from endpoint devices are distributed across the CPU cores.
