Hi All,
I have a doubt, the MSI domains are handled differently in different RC drivers.
Some drivers use irq_domain_add_linear alone, and some use pci_msi_create_irq_domain also to handle MSI.
In most of the 32-bit architectures only irq_domain_add_linear is used and in 64 bit drivers both pci_msi_create_irq_domain and irq_domain_add_linear are used.
So is this because of architecture difference between ARM and ARM64 ?
Thanks & Regards, valmiki
