[virtio] Address review feedback - simplify documentation and fix cppcheck

2025-12-04T22:42:36Z

- Removed TESTING.md and SPECIFICATIONS.md as requested - Simplified README.md with essential information only - Added Chinese version README_zh.md with language links - Fixed cppcheck AST error by rewriting version check condition - Changed from (version != 1 && version != 2) to ((version < 1) || (version > 2)) Co-authored-by: BernardXiong <1241087+BernardXiong@users.noreply.github.com>

[virtio] Add modern VirtIO (v1.2.0) support with backward compatibility

2025-12-04T15:41:45Z

- Updated Kconfig to support both legacy and modern versions - Added version field to virtio_device structure - Implemented 64-bit feature negotiation for modern virtio - Updated queue initialization for modern virtio (separate desc/driver/device areas) - Added FEATURES_OK check for modern virtio - Updated all device drivers (blk, net, console, gpu, input) to use new APIs - Updated BSP drivers to accept both version 1 (legacy) and version 2 (modern) Co-authored-by: BernardXiong <1241087+BernardXiong@users.noreply.github.com>

[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][spi flash]: 优化GD32F470 SPI Flash初始化和UART0配置 (#10983)

2025-12-01T06:47:53Z

* feat(gd32): 优化GD32F470 SPI Flash初始化和UART0配置主要修改： 1. SPI Flash初始化优化 - 添加可配置的SPI Flash自动初始化选项(BSP_USING_SPI_FLASH) - 支持按SPI总线独立配置Flash初始化(BSP_USING_SPIx_FLASH) - 避免SPI Flash初始化与其他SPI设备(如OLED、WIFI)冲突 - 添加SPI5 Flash支持 - 修改drv_spi_flash.c，仅在明确配置的SPI总线上初始化Flash 2. UART0配置修复 - 将UART0的AFIO默认值从AF1改为AF7 - 修复串口无响应问题这些修改使得用户可以更灵活地配置SPI Flash初始化，避免自动初始化导致的设备冲突问题。 * feat(gd32): 解耦SPI Flash与SFUD的依赖关系
