fn send_ipi_many(&self, hart_mask: HartMask) -> SbiRet;
}Expand description

Required methods
fn send_ipi_many(&self, hart_mask: HartMask) -> SbiRet
fn send_ipi_many(&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.
