bsp: qemu-virt64-riscv: remove config RISCV_S_MODE

2025-01-10T09:14:13Z

RISCV_S_MODE configuration only affects the code in libcpu/risc-v/virt64, and the only bsp using this libcpu is qemu-virt64-riscv. Considering s-mode is the default mode RT-Thread running on virt64 machine, it seems unnecessary to make RISCV_S_MODE a Kconfig option. Solution: Remove RISCV_S_MODE from Kconfig and define it as a macro in the code in libcpu/risc-v/virt64. Plus, due to this macro is only related to virt64, rename RISCV_S_MODE to RISCV_VIRT64_S_MODE. Update the .config/rtconfig.h in this patch. Signed-off-by: Chen Wang

feat: libcpu/risc-v: unify interrupt & IO on rv64

2024-09-11T22:06:51Z

This patch aims to unify the two currently separated RISC-V 64-bit architecture ports, 'virt64' and 'c906', into a single generic 'common64' port. The changes include renaming files and updating includes to use a unified 'interrupt.h' header, as well as making adjustments to IO and trap handling to be more consistent between the two architectures. Changes: - Renamed 'rt_interrupt.h' to 'interrupt.h' and updated includes accordingly. - Unified IO register access functions in 'riscv_io.h'. - Added 'opcode.h' for portable assembly support. - Updated 'plic.c' and 'plic.h' to handle interrupts in a unified manner. - Modified 'trap.c' to handle exceptions and interrupts consistently for 'rv64'.
