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'], =09=09if_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. Signed-off-by: Greg Kurz --- The various comments motivated me enough for another round, which is basically to split the cleanup out to a separate patch and use CONFIG_PSERIES in hw/intc/meson.build as suggested by Cedric. v3: - move cleanup to a separate patch v2: - check CONFIG_KVM in the meson.build as suggested by Paolo --- hw/intc/Kconfig | 10 ---------- hw/intc/meson.build | 9 ++++++--- hw/ppc/Kconfig | 5 ----- 3 files changed, 6 insertions(+), 18 deletions(-) diff --git a/hw/intc/Kconfig b/hw/intc/Kconfig index 468d548ca771..fa2695e58d56 100644 --- a/hw/intc/Kconfig +++ b/hw/intc/Kconfig @@ -30,11 +30,6 @@ config ARM_GIC_KVM default y depends on ARM_GIC && KVM =20 -config OPENPIC_KVM - bool - default y - depends on OPENPIC && KVM - config XICS bool depends on POWERNV || PSERIES @@ -43,11 +38,6 @@ config XICS_SPAPR bool select XICS =20 -config XICS_KVM - bool - default y - depends on XICS && KVM - config ALLWINNER_A10_PIC bool =20 diff --git a/hw/intc/meson.build b/hw/intc/meson.build index 68da782ad2c5..b6c9218908e3 100644 --- a/hw/intc/meson.build +++ b/hw/intc/meson.build @@ -39,7 +39,8 @@ specific_ss.add(when: 'CONFIG_LOONGSON_LIOINTC', if_true:= files('loongson_lioint specific_ss.add(when: 'CONFIG_MIPS_CPS', if_true: files('mips_gic.c')) specific_ss.add(when: 'CONFIG_OMAP', if_true: files('omap_intc.c')) specific_ss.add(when: 'CONFIG_OMPIC', if_true: files('ompic.c')) -specific_ss.add(when: 'CONFIG_OPENPIC_KVM', if_true: files('openpic_kvm.c'= )) +specific_ss.add(when: ['CONFIG_KVM', 'CONFIG_OPENPIC'], +=09=09if_true: files('openpic_kvm.c')) specific_ss.add(when: 'CONFIG_POWERNV', if_true: files('xics_pnv.c', 'pnv_= xive.c')) specific_ss.add(when: 'CONFIG_PPC_UIC', if_true: files('ppc-uic.c')) specific_ss.add(when: 'CONFIG_RASPI', if_true: files('bcm2835_ic.c', 'bcm2= 836_control.c')) @@ -50,8 +51,10 @@ specific_ss.add(when: 'CONFIG_SH4', if_true: files('sh_i= ntc.c')) specific_ss.add(when: 'CONFIG_SIFIVE_CLINT', if_true: files('sifive_clint.= c')) specific_ss.add(when: 'CONFIG_SIFIVE_PLIC', if_true: files('sifive_plic.c'= )) specific_ss.add(when: 'CONFIG_XICS', if_true: files('xics.c')) -specific_ss.add(when: 'CONFIG_XICS_KVM', if_true: files('xics_kvm.c')) +specific_ss.add(when: ['CONFIG_KVM', 'CONFIG_XICS'], +=09=09if_true: files('xics_kvm.c')) specific_ss.add(when: 'CONFIG_XICS_SPAPR', if_true: files('xics_spapr.c')) specific_ss.add(when: 'CONFIG_XIVE', if_true: files('xive.c')) -specific_ss.add(when: 'CONFIG_XIVE_KVM', if_true: files('spapr_xive_kvm.c'= )) +specific_ss.add(when: ['CONFIG_KVM', 'CONFIG_XIVE'], +=09=09if_true: files('spapr_xive_kvm.c')) specific_ss.add(when: 'CONFIG_XIVE_SPAPR', if_true: files('spapr_xive.c')) diff --git a/hw/ppc/Kconfig b/hw/ppc/Kconfig index 982d55f5875c..e35710c7c368 100644 --- a/hw/ppc/Kconfig +++ b/hw/ppc/Kconfig @@ -139,11 +139,6 @@ config XIVE_SPAPR depends on PSERIES select XIVE =20 -config XIVE_KVM - bool - default y - depends on XIVE_SPAPR && KVM - # Only used by 64-bit targets config FW_CFG_PPC bool
