However no driver produces any PCI interface node. Hence, PCI tests cannot be run with aarch64 binary. Add a GPEX driver node that produces a pci interface node. This latter then can be consumed by all the pci tests. One of the first motivation was to be able to run the virtio-iommu-pci tests. We still face an issue with pci hotplug tests as hotplug cannot happen on the pcie root bus and require a generic root port. This will be addressed later on. We force cpu=max along with aarch64/virt machine as some PCI tests require high MMIO regions to be available. Signed-off-by: Eric Auger --- v3 -> v4: - properly handle le/cpu conversions on config access v2 -> v3: - force cpu=max with aarch64/virt v1 -> v2: - copyright updated to 2022 - QPCIBusARM renamed into QGenericPCIBus - QGenericPCIHost declarations and definitions moved in the same place as the generic pci implementation - rename pci-arm.c/h in generic-pcihost.c/h and remove any ref to ARM there - remove qos_node_produces_opts, qpci_new_arm, qpci_free_arm - ecam_alloc_ptr now is a field of QGenericPCIBus and not QPCIBus - new libqos_init to create generic-pcihost driver that contains pci-bus-generic - QGenericPCIHost moved in the same place as the generic pci bindings Signed-off-by: Eric Auger --- tests/qtest/libqos/arm-virt-machine.c | 19 ++- tests/qtest/libqos/generic-pcihost.c | 231 ++++++++++++++++++++++++++ tests/qtest/libqos/generic-pcihost.h | 54 ++++++ tests/qtest/libqos/meson.build | 1 + 4 files changed, 301 insertions(+), 4 deletions(-) create mode 100644 tests/qtest/libqos/generic-pcihost.c create mode 100644 tests/qtest/libqos/generic-pcihost.h diff --git a/tests/qtest/libqos/arm-virt-machine.c b/tests/qtest/libqos/arm-virt-machine.c index e0f5932284..96da0dde54 100644 --- a/tests/qtest/libqos/arm-virt-machine.c +++ b/tests/qtest/libqos/arm-virt-machine.c @@ -22,6 +22,8 @@ #include "malloc.h" #include "qgraph.h" #include "virtio-mmio.h" +#include "generic-pcihost.h" +#include "hw/pci/pci_regs.h" #define ARM_PAGE_SIZE 4096 #define VIRTIO_MMIO_BASE_ADDR 0x0A003E00 @@ -35,6 +37,7 @@ struct QVirtMachine { QOSGraphObject obj;
