[Qemu-arm] [PATCH v3 1/3] hw/pci-host/gpex: Set INTx index/gsi mapping |
Date: |
Tue, 13 Jun 2017 15:31:15 +0200 |
From: Pranavkumar Sawargaonkar <address@hidden>
To implement INTx to gsi routing we need to pass the gpex host
bridge the gsi associated to each INTx index. Let's introduce
irq_num array and gpex_set_irq_num setter function.
