The previous version failed to build on alpha:
debian/virtio-modules-4.19.0-3-alpha-generic-di lib/modules/4.19.0-3-alpha-generic/kernel/drivers/i2c/i2c-core.ko
debian/i2c-modules-4.19.0-3-alpha-generic-di lib/modules/4.19.0-3-alpha-generic/kernel/drivers/i2c/i2c-core.ko
and sparc64:
debian/virtio-modules-4.19.0-3-sparc64-di lib/modules/4.19.0-3-sparc64/kernel/drivers/i2c/i2c-core.ko
debian/nic-modules-4.19.0-3-sparc64-di lib/modules/4.19.0-3-sparc64/kernel/drivers/i2c/i2c-core.ko
sparc64 was missing a i2c-modules package, but adding that just gets
it to the same state as alpha. On both architectures drm_kms_helper
is included in the virtio-modules package as a dependency of
virtio-gpu, and then i2c-core is included as a dependency of
drm_kms_helper.
I don't think it makes sense to make virtio-modules directly depend on
i2c-modules. (In fact I think virtio-modules was a mistake entirely.)
Instead, for all configurations that enable both DRM and virtio:
1. Add an fb-modules package if it doesn't already exist
2. Include drm and drm_kms_helper in it
These drivers depend on the corresponding net drivers, or at least
common modules built under drivers/net/ethernet, currently leading
to duplicate modules.
I don't want to resolve this by adding a dependency between
nic-modules and scsi-modules, as that would pull in both into
installer images that previously only needed one set of drivers. I
also don't want to add the common modules into kernel-image as that
would bloat all installer images. Instead, put the drivers in a new
package and we can work out which installer images should include it
later.
Build scsi-nic-modules for all architectures/flavours that build
scsi-modules using the common module list now.
Merge the configuration and default-configuration directories,
using per-architecture overrides in package-list.
This requires a newer version of kernel-wedge to support
Depends_<arch> properly.
The only immediate change to debian/control is to remove the
different description for nic-modules on sparc64.
