Re: [libvirt] [PATCH 3/4] tests: Prepare to have different usable GIC versions

Now that we choose the GIC version based on hardware features when no <gic/> element has been provided, we need a way to fake the GIC capabilities of the host. Update the qemuxml2argv and qemuxml2xml tests to allow this. --- tests/qemuxml2argvtest.c | 77 ++++++++++++++++++----- tests/qemuxml2xmltest.c | 159 ++++++++++++++++++++++++++++------------------- 2 files changed, 159 insertions(+), 77 deletions(-) diff --git a/tests/qemuxml2argvtest.c b/tests/qemuxml2argvtest.c index e41444d..b081634 100644 --- a/tests/qemuxml2argvtest.c +++ b/tests/qemuxml2argvtest.c @@ -34,6 +34,13 @@ static const char *abs_top_srcdir; static virQEMUDriver driver; +enum { + GIC_NONE = 0, + GIC_V2, + GIC_V3, + GIC_BOTH, +}; + static unsigned char * fakeSecretGetValue(virSecretPtr obj ATTRIBUTE_UNUSED, size_t *value_size, @@ -452,6 +459,49 @@ testAddCPUModels(virQEMUCapsPtr caps, bool skipLegacy) static int +testPrepareExtraFlags(struct testInfo *info, + bool skipLegacyCPUs, + int gic) +{ + virGICCapability *gicCapabilities = NULL; + size_t ngicCapabilities = 0; + int ret = -1; + + if (!(info->extraFlags = virQEMUCapsNew())) + goto out; + + if (testAddCPUModels(info->extraFlags, skipLegacyCPUs) < 0) + goto out; + + if (VIR_ALLOC_N(gicCapabilities, 2) < 0) + goto out; + +# define IMPL_BOTH \ + VIR_GIC_IMPLEMENTATION_KERNEL|VIR_GIC_IMPLEMENTATION_EMULATED + + if (gic & GIC_V2) { + gicCapabilities[ngicCapabilities].version = VIR_GIC_VERSION_2; + gicCapabilities[ngicCapabilities].implementation = IMPL_BOTH; + ngicCapabilities++; + } + if (gic & GIC_V3) { + gicCapabilities[ngicCapabilities].version = VIR_GIC_VERSION_3; + gicCapabilities[ngicCapabilities].implementation = IMPL_BOTH; + ngicCapabilities++; + } + +# undef IMPL_BOTH + + virQEMUCapsSetGICCapabilities(info->extraFlags, + gicCapabilities, ngicCapabilities); + + ret = 0; + + out: + return ret; +}
