Re: [libvirt] [PATCH 2/6] conf: new functions to check if PCI address is wanted/present

In order to allow <address type='pci'/> with no other attributes to mean "I want a PCI address, but any PCI address will do" (just as having no <address> at all usually indicates), we will need to change several places in the code from a simple "info->type == (or !=) VIR_DOMAIN_DEVICE_ADDRESS_TYPE_(PCI|NONE)" into something slightly more complex, this patch adds to new functions that take a virDomainDeviceInfoPtr and return true/false depending on 1) whether the current state of the info indicates that we "want" a PCI address for this device (virDeviceInfoPCIAddressWanted()) and 2) whether this device already has a valid PCI address (virDeviceInfoPCIAddressPresent()). Both of these functions required the simpler check for whether a pci address is "empty" (i.e. all of its attributes are 0, which can never happen in a real PCI address, since slot 0 of bus 0 of domain 0 is always reserved), so that function is also added. --- src/conf/device_conf.h | 21 +++++++++++++++++++++ 1 file changed, 21 insertions(+) diff --git a/src/conf/device_conf.h b/src/conf/device_conf.h index 46c720d..847564b 100644 --- a/src/conf/device_conf.h +++ b/src/conf/device_conf.h @@ -184,6 +184,27 @@ typedef struct _virDomainDeviceInfo { int virPCIDeviceAddressIsValid(virPCIDeviceAddressPtr addr, bool report); +static inline bool
