3. 2025年Q3:扩展硬件适配能力 超睿科技计划在2025年第三季度拓宽RT-Thread对RISC-V硬件的适配性,包括支持在更多特权级运行、支持CPU Hotplug等特性、以及更加广泛的处理器核-簇结构。这将使得RT-Thread Smart在多核处理环境下更加灵活,并能更好地应对不同应用场景下的需求。 关于超睿科技 超睿自主设计开发采用RISC...
与 sbi_cpuidle 驱动用到 cpu_suspend 函数类似,swsusp_arch_suspend 函数也采用这种巧妙的 if/else 格式,对该函数进行反汇编,可以看到在 __cpu_suspend_enter 函数中保存的 ra 就是下一条指令 beqz 的地址。休眠或者挂起过程中,__cpu_suspend_enter 设置 a0 = 1,执行 if 分支;恢复或者(休眠)唤醒过程中,...

(HSM) SBI extension starting from OpenSBI v0.7. HSM extension allows S-mode software to boot all the harts a defined order rather than legacy method of random booting of harts. As a result, many required features such as CPU hotplug, kexec/kdump can also be supported easily in S-mode. ...

As a result, many required features such as CPU hotplug, kexec/kdump can also be supported easily in S-mode. HSM extension in OpenSBI is implemented in a non-backward compatible manner to reduce the maintenance burden and avoid confusion. That's why, any S-mode software using OpenSBI will ...
