This patch adds inter-processor interrupt support using K230 mailbox device to improve the RPMsg efficiency. The polling logic has been dropped. Major changes: - in arch/risc-v/include/k230: - irq.h add IRQ for IPI devices - in arch/risc-v/src/k230: - Kconfig add IPI related config, increase polling delay - Make.defs add k230_ipi.c to CHIP_SRCS - k230_hart.c fix typo, add notes of zero MISA reading w/ NUTTSBI - k230_irq.c use K230_PLIC_IRQS as ext IRQ limit to support IPI - k230_rptun.c use IPI instead of polling - in boards/risc-v/k230/canmv230/configs - master enable IPI support - remote enable IPI, TMPFS, RPMSGFS etc New additions: - in arch/risc-v/src/k230: - k230_ipi.h add K230 IPI related defintions - k230_ipi.c add K230 IPI driver Signed-off-by: Yanfeng Liu <yfliu2008@qq.com> |
