[libcpu-riscv]: [surpport SMP]: Add SMP support for qemu-virt64-riscv

2025-12-04T07:42:09Z

1.Add the necessary function declarations for SMP enablement and implement the corresponding functionalities, including rt_hw_secondary_cpu_up, secondary_cpu_entry, rt_hw_local_irq_disable, rt_hw_local_irq_enable, rt_hw_secondary_cpu_idle_exec, rt_hw_spin_lock_init, rt_hw_spin_lock, rt_hw_spin_unlock, rt_hw_ipi_send, rt_hw_interrupt_set_priority, rt_hw_interrupt_get_priority, rt_hw_ipi_init, rt_hw_ipi_handler_install, and rt_hw_ipi_handler. 2.In the two functions (rt_hw_context_switch_to and rt_hw_context_switch) in context_gcc.S, add a call to rt_cpus_lock_status_restore to update the scheduler information. 3.If the MMU is enabled, use the .percpu section and record different hartids by configuring special page tables; if the MMU is not enabled, record them directly in the satp register. Additionally, add dynamic startup based on core configuration.The .percpu section is only used when both ARCH_MM_MMU and RT_USING_SMP are enabled. However, there is a certain amount of space waste since no macro guard is added for it in the link script currently. 4.The physical memory of QEMU started in CI is 128MB, so RT_HW_PAGE_END is modified from the original +256MB to +128MB. Modify the SConscript file under the common64 directory to include common/atomic_riscv.c in the compilation process. Signed-off-by: Mengchen Teng

bsp/qemu-virt64-riscv: disable RT_USING_UTEST

2025-09-22T09:41:06Z

utest framework is an optional module and should be enabled when running utest. So RT_USING_UTEST should not be enabled by default. Disable it now. Signed-off-by: Chen Wang

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

bsp: qemu-virt64-riscv: Kconfig: remove duplicated RT_USING_VIRTIO

2024-12-25T05:42:05Z

There is problem in the Kconfig of qemu-virt64-riscv. RT_USING_VIRTIO is already defined in components/drivers/virtio/Kconfig, so it should not be defined again in the BSP kconfig. The solution is to rename RT_USING_VIRTIO to BSP_USING_VIRTIO. Also, refer to the configuration method for virtio device drivers in bsp/qemu-virt64-aarch64/drivers/Kconfig to rewrite the configuration of BSP_USING_VIRTIO_xxx. Updated default .config/rtconfig.h at the same time. Signed-off-by: Chen Wang

bsp: qemu-virt64-riscv: update README for booting with rootfs

2024-12-19T02:08:03Z

Now lwext4 is ready, and qemu-virt64-riscv smart can boot with rootfs. Updated README to introduce this. This patch also replace qemu-nographic.sh with run.sh, which has a more simple name and more robust to launch rootfs image binary. TBD: qemu-nographic.bat is not touched, hope some guys from Windows can give a hand. Signed-off-by: Chen Wang
