Also, to make this more obvious, guard them via a pci_available boolean (which also can be reused in other places). Fixes: e1d4fb2de ("kvm-irqchip: x86: add msi route notify fn") Fixes: 767a554a0 ("kvm-all: Pass requester ID to MSI routing functions") Signed-off-by: Cornelia Huck --- accel/kvm/kvm-all.c | 6 +++--- hw/pci/pci-stub.c | 15 +++++++++++++++ hw/pci/pci.c | 2 ++ include/hw/pci/pci.h | 2 ++ 4 files changed, 22 insertions(+), 3 deletions(-) diff --git a/accel/kvm/kvm-all.c b/accel/kvm/kvm-all.c index 46ce479dc3..f85553a851 100644 --- a/accel/kvm/kvm-all.c +++ b/accel/kvm/kvm-all.c @@ -1248,7 +1248,7 @@ int kvm_irqchip_add_msi_route(KVMState *s, int vector, PCIDevice *dev) int virq; MSIMessage msg = {0, 0}; - if (dev) { + if (pci_available && dev) { msg = pci_get_msi_message(dev, vector); } @@ -1271,7 +1271,7 @@ int kvm_irqchip_add_msi_route(KVMState *s, int vector, PCIDevice *dev) kroute.u.msi.address_lo = (uint32_t)msg.address; kroute.u.msi.address_hi = msg.address >> 32; kroute.u.msi.data = le32_to_cpu(msg.data); - if (kvm_msi_devid_required()) { + if (pci_available && kvm_msi_devid_required()) { kroute.flags = KVM_MSI_VALID_DEVID; kroute.u.msi.devid = pci_requester_id(dev); } @@ -1309,7 +1309,7 @@ int kvm_irqchip_update_msi_route(KVMState *s, int virq, MSIMessage msg, kroute.u.msi.address_lo = (uint32_t)msg.address; kroute.u.msi.address_hi = msg.address >> 32; kroute.u.msi.data = le32_to_cpu(msg.data); - if (kvm_msi_devid_required()) { + if (pci_available && kvm_msi_devid_required()) { kroute.flags = KVM_MSI_VALID_DEVID; kroute.u.msi.devid = pci_requester_id(dev); } diff --git a/hw/pci/pci-stub.c b/hw/pci/pci-stub.c index ecad664946..ace43821ca 100644 --- a/hw/pci/pci-stub.c +++ b/hw/pci/pci-stub.c @@ -23,10 +23,12 @@ #include "monitor/monitor.h" #include "qapi/qmp/qerror.h" #include "hw/pci/pci.h" +#include "hw/pci/msi.h" #include "qmp-commands.h" #include "hw/pci/msi.h" bool msi_nonbroken; +bool pci_available; PciInfoList *qmp_query_pci(Error **errp) { @@ -38,3 +40,16 @@ void hmp_pcie_aer_inject_error(Monitor *mon, const QDict *qdict) { monitor_printf(mon, "PCI devices not supported\n"); } + +/* kvm-all wants this */ +MSIMessage pci_get_msi_message(PCIDevice *dev, int vector) +{ + g_assert(false); + return (MSIMessage){}; +} + +uint16_t pci_requester_id(PCIDevice *dev) +{ + g_assert(false); + return 0; +} diff --git a/hw/pci/pci.c b/hw/pci/pci.c index 258fbe51e2..26f346db2c 100644 --- a/hw/pci/pci.c +++ b/hw/pci/pci.c @@ -49,6 +49,8 @@ # define PCI_DPRINTF(format, ...) do { } while (0) #endif +bool pci_available = true; + static void pcibus_dev_print(Monitor *mon, DeviceState *dev, int indent); static char *pcibus_get_dev_path(DeviceState *dev); static char *pcibus_get_fw_dev_path(DeviceState *dev); diff --git a/include/hw/pci/pci.h b/include/hw/pci/pci.h index e598b095eb..8bb6449dd7 100644 --- a/include/hw/pci/pci.h +++ b/include/hw/pci/pci.h @@ -10,6 +10,8 @@ #include "hw/pci/pcie.h" +extern bool pci_available; + /* PCI bus */ #define PCI_DEVFN(slot, func) ((((slot) & 0x1f) << 3) | ((func) & 0x07)) -- 2.13.5
