ppc: Fix build with --without-default-devices
Linking of the qemu-system-ppc64 fails on a POWER9 host when
--without-default-devices is passed to configure:
$ ./configure --without-default-devices \
--target-list=ppc64-softmmu && make
...
libqemu-ppc64-softmmu.fa.p/hw_ppc_e500.c.o: In function `ppce500_init_mpic_kvm':
/home/greg/Work/qemu/qemu-ppc/build/../hw/ppc/e500.c:777: undefined reference to `kvm_openpic_connect_vcpu'
libqemu-ppc64-softmmu.fa.p/hw_ppc_spapr_irq.c.o: In function `spapr_irq_check':
/home/greg/Work/qemu/qemu-ppc/build/../hw/ppc/spapr_irq.c:189: undefined reference to `xics_kvm_has_broken_disconnect'
libqemu-ppc64-softmmu.fa.p/hw_intc_spapr_xive.c.o: In function `spapr_xive_post_load':
/home/greg/Work/qemu/qemu-ppc/build/../hw/intc/spapr_xive.c:530: undefined reference to `kvmppc_xive_post_load'
... and tons of other symbols belonging to the KVM backend of the
openpic, XICS and XIVE interrupt controllers.
It turns out that OPENPIC_KVM, XICS_KVM and XIVE_KVM are marked
to depend on KVM but this has no effect when minikconf runs in
allnoconfig mode. Such reverse dependencies should rather be
handled with a 'select' statement, eg.
config OPENPIC
select OPENPIC_KVM if KVM
or even better by getting rid of the intermediate _KVM config
and directly checking CONFIG_KVM in the meson.build file:
specific_ss.add(when: ['CONFIG_KVM', 'CONFIG_OPENPIC'],
if_true: files('openpic_kvm.c'))
Go for the latter with OPENPIC, XICS and XIVE.
This went unnoticed so far because CI doesn't test the build with
--without-default-devices and KVM enabled on a POWER host.
