Function sbi_rt::system_reset

pub fn system_reset<T, R>(reset_type: T, reset_reason: R) -> SbiRet
where
    T: ResetType,
    R: ResetReason,

Reset the system based on provided reset_type and reset_reason.

This is a synchronous call and does not return if it succeeds.

Warm reboot and cold reboot

When supervisor software is running natively, the SBI implementation is machine mode firmware. In this case, shutdown is equivalent to physical power down of the entire system, and cold reboot is equivalent to a physical power cycle of the entire system. Further, warm reboot is equivalent to a power cycle of the main processor and parts of the system but not the entire system.

For example, on a server class system with a BMC (board management controller), a warm reboot will not power cycle the BMC whereas a cold reboot will definitely power cycle the BMC.

When supervisor software is running inside a virtual machine, the SBI implementation is a hypervisor. The shutdown, cold reboot and warm reboot will behave functionally the same as the native case but might not result in any physical power changes.

This function is defined in RISC-V SBI Specification chapter 10.1.
