pub trait Ipi {
// Required method
fn send_ipi(&self, hart_mask: HartMask) -> SbiRet;
}Expand description
Inter-processor interrupt support.
Required Methods§
Sourcefn send_ipi(&self, hart_mask: HartMask) -> SbiRet
fn send_ipi(&self, hart_mask: HartMask) -> SbiRet
Send an inter-processor interrupt to all the harts defined in hart_mask.
Inter-processor interrupts manifest at the receiving harts as the supervisor software interrupts.
§Return value
Should return SbiRet::success() if IPI was sent to all the targeted harts successfully.
