linux-yocto_virtualization.inc: If using externalsrc adjust dependency
From: Mark Hatle <[email protected]>
When using externalsrc, the system will disable a number of tasks such as
do_validate_branches, do_unpack and do_patch. The do_kernel_metadata task
is configured to run after do_validate_branches do_unpack and before
do_patch. Since all of these have been removed, the task will never
run.
The do_kernel_metadata task is responsible for populating the
recipe-sysroot-native/kcfg directory via it's own dependency to
yocto-cfg-fragments-native:do_populate_sysroot.
Without do_kernel_metadata running, do_kernel_configme will fail to run
with errors like:
ERROR: linux-xlnx-6.6.40+git-r0 do_kernel_configme: Feature
'../recipe-sysroot-native/kcfg/cfg/virtio.scc' not found, this will cause
configuration failures.
ERROR: linux-xlnx-6.6.40+git-r0 do_kernel_configme: Check the SRC_URI for
meta-data repositories or directories that may be missing
ERROR: linux-xlnx-6.6.40+git-r0 do_kernel_configme: Set
KERNEL_DANGLING_FEATURES_WARN_ONLY to ignore this issue
Fix this issue by detecting if we're running with externalsrc, and then
adding the task do_kernel_metadata (from the current recipe) as a
dependency of do_kernel_configme.
To reproduce th original issue:
$ . ./oe-initbuild-env
$ bitbake linux-yocto -c patch
$ cp -r tmp/work-shared/<machine>/kernel-source linux-yocto
edit the conf/local.conf adding:
DISTRO_FEATURES:append = " virtualization"
INHERIT += "externalsrc"
EXTERNALSRC:pn-linux-yocto = "${TOPDIR}/linux-yocto"
$ rm -rf tmp
$ bitbake linux-yocto -c menuconfig

This can be written more readable as:
do_kernel_configme[depends] += "${@d.getVar('PN') + ':do_kernel_metadata' if
bb.data.inherits_class('externalsrc', d) else ''}"
I followed the existing style in the recipe of the other [depends] line above.
