2020-11-05hw/9pfs: Fix Kconfig dependency problem between 9pfs and XenPhilippe Mathieu-Daudé
Commit b2c00bce54c ("meson: convert hw/9pfs, cleanup") introduced CONFIG_9PFS (probably a wrong conflict resolution). This config is not used anywhere. Backends depend on CONFIG_FSDEV_9P which itself depends on CONFIG_VIRTFS. Remove the invalid CONFIG_9PFS and use CONFIG_FSDEV_9P instead, to fix the './configure --without-default-devices --enable-xen' build: /usr/bin/ld: libcommon.fa.p/hw_xen_xen-legacy-backend.c.o: in function `xen_be_register_common': hw/xen/xen-legacy-backend.c:754: undefined reference to `xen_9pfs_ops' /usr/bin/ld: libcommon.fa.p/fsdev_qemu-fsdev.c.o:(.data.rel+0x8): undefined reference to `local_ops' /usr/bin/ld: libcommon.fa.p/fsdev_qemu-fsdev.c.o:(.data.rel+0x20): undefined reference to `synth_ops' /usr/bin/ld: libcommon.fa.p/fsdev_qemu-fsdev.c.o:(.data.rel+0x38): undefined reference to `proxy_ops' collect2: error: ld returned 1 exit status Fixes: b2c00bce54c ("meson: convert hw/9pfs, cleanup") Suggested-by: Paolo Bonzini <pbonzini@redhat.com> Acked-by: Greg Kurz <groug@kaod.org> Tested-by: Greg Kurz <groug@kaod.org> Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Acked-by: Christian Schoenebeck <qemu_oss@crudebyte.com> Message-Id: <20201104115706.3101190-3-philmd@redhat.com> Signed-off-by: Christian Schoenebeck <qemu_oss@crudebyte.com>

2019-08-209p: simplify source file selectionPaolo Bonzini
Express the complex conditions in Kconfig rather than Makefiles, since Kconfig is better suited at expressing dependencies and detecting contradictions. Cc: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2019-03-07build: switch to KconfigPaolo Bonzini
The make_device_config.sh script is replaced by minikconf, which is modified to support the same command line as its predecessor. The roots of the parsing are default-configs/*.mak, Kconfig.host and hw/Kconfig. One difference with make_device_config.sh is that all symbols have to be defined in a Kconfig file, including those coming from the configure script. This is the reason for the Kconfig.host file introduced in the previous patch. Whenever a file in default-configs/*.mak used $(...) to refer to a config-host.mak symbol, this is replaced by a Kconfig dependency; this part must be done already in this patch for bisectability.

2019-03-07kconfig: introduce kconfig filesPaolo Bonzini
The Kconfig files were generated mostly with this script: for i in `grep -ho CONFIG_[A-Z0-9_]* default-configs/* | sort -u`; do set fnord `git grep -lw $i -- 'hw/*/Makefile.objs' ` shift if test $# = 1; then cat >> $(dirname $1)/Kconfig << EOF config ${i#CONFIG_} bool EOF git add $(dirname $1)/Kconfig else echo $i $* fi done sed -i '$d' hw/*/Kconfig for i in hw/*; do if test -d $i && ! test -f $i/Kconfig; then touch $i/Kconfig git add $i/Kconfig fi done Whenever a symbol is referenced from multiple subdirectories, the script prints the list of directories that reference the symbol. These symbols have to be added manually to the Kconfig files. Kconfig.host and hw/Kconfig were created manually.
