Hi -- this fails "make check" on OSX host:

  GTESTER check-qtest-ppc64
qemu-system-ppc64: -object
invalid object type: memory-backend-file
Broken pipe
GTester: last random seed: R02Sc13bf53b8b3055a3c30552f67d7c263b
qpci_plug_device_test(const char *, const char *, uint8_t, const char
*): assertion failed: (!qdict_haskey(response, "error"))
GTester: last random seed: R02Sf3594a21c711ec941d5f4c89724ce12d
qemu-system-ppc64: -device ivshmem-plain,memdev=mb1: 'ivshmem-plain'
is not a valid device model name
Broken pipe

It looks like you've enabled the ivshmem test unconditionally,
but it should only be turned on if CONFIG_EVENTFD is true, see
how we do this for x86:

check-qtest-pci-$(CONFIG_EVENTFD) += tests/ivshmem-test$(EXESUF)
gcov-files-pci-y += hw/misc/ivshmem.c

Q: can we just enable these tests for PCI with
check-qtest-ppc64-y += $(check-qtest-pci-y)
gcov-files-ppc64-y += $(gcov-files-pci-y)

the way we do for i386/x86_64 ? Or is that doing too much
unwanted extra testing?
