Given the vcpumask, check if the IRQ is single destination and return the destination vCPU if so, the address of associated PI descriptor for this vCPU can then be passed to dmar_assign_irte() to set up the posted interrupt IRTE for this device. For fixed mode interrupt delivery, all vCPUs listed in vcpumask should service the interrupt requested. But VT-d PI cannot support multicast/broadcast IRQs, it only supports single CPU destination. So the number of vCPUs shall be 1 in order to handle IRQ in posted mode for this device. Add pid_paddr to struct intr_source. If platform_caps.pi is true and the IRQ is single-destination, pass the physical address of the destination vCPU's PID to ptirq_build_physical_msi and dmar_assign_irte Tracked-On: #4506 Signed-off-by: dongshen <dongsheng.x.zhang@intel.com> Reviewed-by: Eddie Dong <eddie.dong@Intel.com> |
