But I still don't understand and would like to know: (1) why doesn't CONFIG_TRICORE get set by Kconfig anyway, as f4063f9c31 claims to be doing? (2) what are the CONFIG_$ARCH flags for? Apart from this, we don't seem to be using any of them, as demonstrated by the fact that nothing else broke :-) thanks -- PMM

OK, so my patch was sent/tested first: commit f4063f9c319e3924b0c6d09dfe43e94d01253ee0 Message-Id: <20210131111316.232778-6-f4bug@amsat.org> but got merged *after* Bastian's series: commit 582079c9d27fc8cfff9f495072300416e0e4aafe Message-Id: <20210305170045.869437-4-kbastian@mail.uni-paderborn.de> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> > Signed-off-by: Alex Bennée <alex.bennee@linaro.org> > --- > configs/devices/tricore-softmmu/default.mak | 1 + > hw/tricore/Kconfig | 3 +-- > hw/tricore/meson.build | 4 ++-- > 3 files changed, 4 insertions(+), 4 deletions(-) > > diff --git a/configs/devices/tricore-softmmu/default.mak b/configs/devices/tricore-softmmu/default.mak > index 5cc91cebce..724cb85de7 100644 > --- a/configs/devices/tricore-softmmu/default.mak > +++ b/configs/devices/tricore-softmmu/default.mak > @@ -1 +1,2 @@ > +CONFIG_TRITEST=y > CONFIG_TRIBOARD=y > diff --git a/hw/tricore/Kconfig b/hw/tricore/Kconfig > index 506e6183c1..a1b2438d99 100644 > --- a/hw/tricore/Kconfig > +++ b/hw/tricore/Kconfig > @@ -1,9 +1,8 @@ > -config TRICORE > +config TRITEST > bool > > config TRIBOARD > bool > - select TRICORE > select TC27X_SOC > > config TC27X_SOC > diff --git a/hw/tricore/meson.build b/hw/tricore/meson.build > index 47e36bb077..692a4708ba 100644 > --- a/hw/tricore/meson.build > +++ b/hw/tricore/meson.build > @@ -1,6 +1,6 @@ > tricore_ss = ss.source_set() > -tricore_ss.add(when: 'CONFIG_TRICORE', if_true: files('tricore_testboard.c')) > -tricore_ss.add(when: 'CONFIG_TRICORE', if_true: files('tricore_testdevice.c')) > +tricore_ss.add(when: 'CONFIG_TRITEST', if_true: files('tricore_testboard.c')) > +tricore_ss.add(when: 'CONFIG_TRITEST', if_true: files('tricore_testdevice.c')) > tricore_ss.add(when: 'CONFIG_TRIBOARD', if_true: files('triboard.c')) > tricore_ss.add(when: 'CONFIG_TC27X_SOC', if_true: files('tc27x_soc.c')) > >

We know we don't have anything that cares about them, because right now we have a bug where they're never set... -- PMM

Well we have one place at the moment to ensure v7m gets included even if you don't include the various M profile boards: default y if TCG && (ARM || AARCH64) which is because translate.c still currently has a dependency on those bits. Without that you'll get a linker failure with the following build: '../../configure' '--without-default-features' '--target-list=arm-softmmu,aarch64-softmmu' '--with-devices-aarch64=minimal' I thought I'd added that to the build matrix but I can't find it now. > > -- PMM
