It's just RFC for discussion. > If it's a long term solution then how will armv7m and armv7r be > handled? They are likely to need to duplicate a lot of the current > armv7a over-rides too. armv7a and armv7ve are much closer than armv7a and armv7m or armv7r as Khem said in earlier discussion. And maybe it's because fewer people use armv7[rm], but currently these 2 aren't used anywhere as overrides (in layers I've in world builds). > Maybe adding a generic "armv7" over-ride which can be enabled by all > armv7 variants is a better option? Maybe, but that will change how armv7r and armv7m are currently built, I cannot say if for better or worse, I don't use either. > Either way, I'd like to continue cleaning up of the existing armv7a > over-rides (e.g. the libav armv7a specific optimisation is likely > bogus and should be removed, etc). > > > > Signed-off-by: Martin Jansa <[email protected]> > > --- > > meta/conf/machine/include/arm/arch-armv7ve.inc | 3 ++- > > 1 file changed, 2 insertions(+), 1 deletion(-) > > > > diff --git a/meta/conf/machine/include/arm/arch-armv7ve.inc > > b/meta/conf/machine/include/arm/arch-armv7ve.inc > > index 79e1ef6..d0fdff7 100644 > > --- a/meta/conf/machine/include/arm/arch-armv7ve.inc > > +++ b/meta/conf/machine/include/arm/arch-armv7ve.inc > > @@ -3,7 +3,8 @@ DEFAULTTUNE ?= "armv7ve" > > TUNEVALID[armv7ve] = "Enable instructions for ARMv7ve" > > TUNECONFLICTS[armv7ve] = "armv4 armv5 armv6 armv7 armv7a" > > TUNE_CCARGS .= "${@bb.utils.contains('TUNE_FEATURES', 'armv7ve', ' > > -march=armv7ve', '', d)}" > > -MACHINEOVERRIDES =.
