From: Philippe Mathieu-Daudé Date: Tue, 1 Jul 2025 14:08:30 +0000 (+0100) Subject: qtest/bios-tables-test: Add test for when ITS is off on aarch64 X-Git-Tag: v10.1.0-rc0~37^2~23 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f63c6c23fba52b1496420e31299de42fd342a2c6;p=thirdparty%2Fqemu.git qtest/bios-tables-test: Add test for when ITS is off on aarch64 Arm64 GIC ITS (Interrupt Translation Service) is an optional piece of hardware introduced in GICv3 and, being optional, it can be disabled in QEMU aarch64 VMs that support it using machine option "its=off", like, for instance: "-M virt,its=off". In ACPI, the ITS is advertised, if present, in the MADT (aka APIC) table, while the ID mappings from the Root Complex (RC) and from the SMMU nodes to the ITS Group nodes are described in the IORT table. This new test verifies that when the "its=off" option is passed to the machine the ITS-related data is correctly pruned from the ACPI tables. The new blobs for this test will be added in a following commit.
