when enable CONFIG_NEW_VGIC in ARM64 QEMU Platform, it will build failed.
so fix it and make it can select GICV2.

As I said in v1, last time I checked QEMU was only able to support virtualization with GICv3. This is why we added a depends on. If you want to remove it, then I think you ought to explain in the commit message why this is fine. A pointer to the commit or a QEMU version used would be useful. > > Signed-off-by: Dongjiu Geng <gengdongjiu1@gmail.com> > --- > $ make dist-xen XEN_TARGET_ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j10 > make -C xen install > make[1]: Entering directory '/home/workspace/gengdongjiu/old_machine/XEN/xen/xen' > make -f /home/workspace/gengdongjiu/old_machine/XEN/xen/xen/tools/kconfig/Makefile.kconfig ARCH=arm64 SRCARCH=arm HOSTCC="gcc" HOSTCXX="g++" syncconfig > make[2]: Entering directory '/home/workspace/gengdongjiu/old_machine/XEN/xen/xen' > gcc -Wp,-MD,tools/kconfig/.conf.o.d -c -o tools/kconfig/conf.o tools/kconfig/conf.c > gcc -Wp,-MD,tools/kconfig/.confdata.o.d -c -o tools/kconfig/confdata.o tools/kconfig/confdata.c > gcc -Wp,-MD,tools/kconfig/.expr.o.d -c -o tools/kconfig/expr.o tools/kconfig/expr.c > flex -otools/kconfig/lexer.lex.c -L tools/kconfig/lexer.l > bison -o tools/kconfig/parser.tab.c --defines=tools/kconfig/parser.tab.h -t -l tools/kconfig/parser.y > gcc -Wp,-MD,tools/kconfig/.preprocess.o.d -c -o tools/kconfig/preprocess.o tools/kconfig/preprocess.c > gcc -Wp,-MD,tools/kconfig/.symbol.o.d -c -o tools/kconfig/symbol.o tools/kconfig/symbol.c > gcc -Wp,-MD,tools/kconfig/.lexer.lex.o.d -I /home/workspace/gengdongjiu/old_machine/XEN/xen/xen/tools/kconfig -c -o tools/kconfig/lexer.lex.o tools/kconfig/lexer.lex.c > gcc -Wp,-MD,tools/kconfig/.parser.tab.o.d -I /home/workspace/gengdongjiu/old_machine/XEN/xen/xen/tools/kconfig -c -o tools/kconfig/parser.tab.o tools/kconfig/parser.tab.c > gcc -o tools/kconfig/conf tools/kconfig/conf.o tools/kconfig/confdata.o tools/kconfig/expr.o tools/kconfig/lexer.lex.o tools/kconfig/parser.tab.o tools/kconfig/preprocess.o tools/kconfig/symbol.o > tools/kconfig/conf --syncconfig Kconfig > > WARNING: unmet direct dependencies detected for GICV3 > Depends on [n]: ARM_64 [=y] && !NEW_VGIC [=y] > Selected by [y]: > - QEMU [=y] && <choice> && ARM_64 [=y] > > WARNING: unmet direct dependencies detected for GICV3 > Depends on [n]: ARM_64 [=y] && !NEW_VGIC [=y] > Selected by [y]: > - QEMU [=y] && <choice> && ARM_64 [=y] > > WARNING: unmet direct dependencies detected for GICV3 > Depends on [n]: ARM_64 [=y] && !NEW_VGIC [=y] > Selected by [y]: > - QEMU [=y] && <choice> && ARM_64 [=y] > make[2]: Leaving directory '/home/workspace/gengdongjiu/old_machine/XEN/xen/xen' > make -f Rules.mk _install > make[2]: Entering directory '/home/workspace/gengdongjiu/old_machine/XEN/xen/xen' > --- > xen/arch/arm/Kconfig | 5 +++-- > xen/arch/arm/platforms/Kconfig | 1 - > 2 files changed, 3 insertions(+), 3 deletions(-) > > diff --git a/xen/arch/arm/Kconfig b/xen/arch/arm/Kconfig > index ecfa6822e4..373c698018 100644 > --- a/xen/arch/arm/Kconfig > +++ b/xen/arch/arm/Kconfig The change in arch/arm/Kconfig is not really related to this patch. Technically the part in platforms/Kconfig is sufficient.
