From 70bfdce6a1263fd06144ecc1c3727c44e562d89b Mon Sep 17 00:00:00 2001 From: Pranavkumar Sawargaonkar Date: Thu, 14 Sep 2017 18:43:18 +0100 Subject: [PATCH] hw/pci-host/gpex: Set INTx index/gsi mapping 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.
