Adds VM IRQ handling support at OSI layer and adds
corresponding support for EQOS as well.
Need to pass below parameters from DT -
o Number of VM IRQ's assigned per OS/VM.
o Number of VM channels assigned to a VM IRQ.
o List of DMA channels assigned to a VM IRQ.
Below is the sample DT representation -
vm_irq_config: vm-irq-config {
nvidia,num-vm-irqs = <4>;
vm_irq1 {
nvidia,num-vm-channels = <2>;
nvidia,vm-channels = <0 1>;
};
vm_irq2 {
nvidia,num-vm-channels = <2>;
nvidia,vm-channels = <2 3>;
};
vm_irq3 {
nvidia,num-vm-channels = <2>;
nvidia,vm-channels = <4 5>;
};
vm_irq4 {
nvidia,num-vm-channels = <2>;
nvidia,vm-channels = <6 7>;
};
};
ethernet@<base_addr> {
[...]
nvidia,vm-irq-config = <&vm_irq_config>;
[...]
}
