However, some tests are not ready to use the spapr bus, due to a MSI bug. Until it does not get fixed, this flag allows them to skip the test Signed-off-by: Emanuele Giuseppe Esposito Signed-off-by: Paolo Bonzini --- tests/libqos/pci-pc.c | 3 +++ tests/libqos/pci-spapr.c | 3 +++ tests/libqos/pci.c | 14 ++++++++++++++ tests/libqos/pci.h | 4 ++++ 4 files changed, 24 insertions(+) diff --git a/tests/libqos/pci-pc.c b/tests/libqos/pci-pc.c index 041bfed..4247cda 100644 --- a/tests/libqos/pci-pc.c +++ b/tests/libqos/pci-pc.c @@ -123,6 +123,9 @@ void qpci_init_pc(QPCIBusPC *qpci, QTestState *qts, QGu= estAllocator *alloc) { assert(qts); =20 + /* tests can use pci-bus */ + qpci->bus.has_buggy_msi =3D FALSE; + qpci->bus.pio_readb =3D qpci_pc_pio_readb; qpci->bus.pio_readw =3D qpci_pc_pio_readw; qpci->bus.pio_readl =3D qpci_pc_pio_readl; diff --git a/tests/libqos/pci-spapr.c b/tests/libqos/pci-spapr.c index 24f2c2c..502a0e5 100644 --- a/tests/libqos/pci-spapr.c +++ b/tests/libqos/pci-spapr.c @@ -155,6 +155,9 @@ void qpci_init_spapr(QPCIBusSPAPR *qpci, QTestState *qt= s, { assert(qts); =20 + /* tests cannot use spapr, needs to be fixed first */ + qpci->bus.has_buggy_msi =3D TRUE; + qpci->alloc =3D alloc; =20 qpci->bus.pio_readb =3D qpci_spapr_pio_readb; diff --git a/tests/libqos/pci.c b/tests/libqos/pci.c index 8257904..662ee7a 100644 --- a/tests/libqos/pci.c +++ b/tests/libqos/pci.c @@ -51,6 +51,20 @@ void qpci_device_foreach(QPCIBus *bus, int vendor_id, in= t device_id, } } =20 +bool qpci_has_buggy_msi(QPCIDevice *dev) +{ + return dev->bus->has_buggy_msi; +} + +bool qpci_check_buggy_msi(QPCIDevice *dev) +{ + if (qpci_has_buggy_msi(dev)) { + g_test_skip("Skipping due to incomplete support for MSI"); + return true; + } + return false; +} + static void qpci_device_set(QPCIDevice *dev, QPCIBus *bus, int devfn) { g_assert(dev); diff --git a/tests/libqos/pci.h b/tests/libqos/pci.h index 9fd521a..8e1d292 100644 --- a/tests/libqos/pci.h +++ b/tests/libqos/pci.h @@ -53,6 +53,7 @@ struct QPCIBus { QTestState *qts; uint16_t pio_alloc_ptr; uint64_t mmio_alloc_ptr, mmio_limit; + bool has_buggy_msi; /* TRUE for spapr, FALSE for pci */ =20 }; =20 @@ -81,6 +82,9 @@ void qpci_device_foreach(QPCIBus *bus, int vendor_id, int= device_id, QPCIDevice *qpci_device_find(QPCIBus *bus, int devfn); void qpci_device_init(QPCIDevice *dev, QPCIBus *bus, QPCIAddress *addr); =20 +bool qpci_has_buggy_msi(QPCIDevice *dev); +bool qpci_check_buggy_msi(QPCIDevice *dev); + void qpci_device_enable(QPCIDevice *dev); uint8_t qpci_find_capability(QPCIDevice *dev, uint8_t id); void qpci_msix_enable(QPCIDevice *dev); --=20 1.8.3.1
