From ef3d992b904c1523374ad3c6631687a1886ed509 Mon Sep 17 00:00:00 2001 From: Andrew Jones Date: Tue, 30 Jun 2015 14:14:37 +0200 Subject: [PATCH 08/11] kvm: introduce kvm_arch_msi_data_to_gsi Message-id: <1435673680-9996-6-git-send-email-drjones@redhat.com> Patchwork-id: 66573 O-Subject: [AArch64 RHEL-7.2 qemu-kvm-rhev PATCH 5/8] kvm: introduce kvm_arch_msi_data_to_gsi Bugzilla: 1231929 RH-Acked-by: Igor Mammedov RH-Acked-by: Laszlo Ersek RH-Acked-by: Michael S. Tsirkin Author: Eric Auger On ARM the MSI data corresponds to the shared peripheral interrupt (SPI) ID. This latter equals to the SPI index + 32. to retrieve the SPI index, matching the gsi, an architecture specific function is introduced.
