Hi,
In most of the RP drivers, why two irq chips are being used for MSI ?
One at irq_domain_set_info (which uses irq_compose_msi_msg and irq_set_affinity methods) and another being registered with struct msi_domain_info (which uses irq_mask/irq_unmask methods).
When will each chip be used w.r.t to virq ?
Thanks, Valmiki
