UBUNTU: [Debian] dkms-build -- use fakeroot if not running as root
Some dkms builds require running as root, or at least the illusion of
doing so. However we need to do dkms builds before deleting the
flavour build directory in order to sign the modules, and this may
happen without fakeroot. Detect whether or not dkms-build has been
invoked as root, and if not use fakeroot to do the dkms build.
We no longer need to generate signatures for nvidia modules during our
kernel build, as they are signed using the ubuntu drivers key. Remove
support for building the nvidia modules.
We must still keep the dkms-build--* scripts for now, as our tooling
currently syncs these scripts from the kernel tree into
linux-restricted-modules.
This is the naive approach, simply changing ownership to root:root for
all files which might have been installed during the build phase. May
want to do something smarter wrt types of files, but the end result is
likely to be the same.
UBUNTU: [Debian] exclude $(DEBIAN)/__abi.current from linux-source
Previously install-source ran before the flavour install, but that is
no longer the case. As a result the __abi.current driectory ends up
in the linux-source package. Explicitly exclude it when installing
files for linux-source.
UBUNTU: [Debian] run install-$(flavour) targets during build phase
Move installation of files from the flavour build directories to the
build phase. This results in cleaning up of one flavour build
directory before starting the build of the next flavour, significantly
reducing the amount of space needed on builders.
Note that this will result in incorrect ownership of files in cases
where the build and binary phases of building packages are run
separately. This will be addressed in a later commit.
UBUNTU: [Debian] use stamps for flavour install targets
In preparation for moving installation of files from the flavour
build directories over to the build phase, convert relevant install-*
targets to use stamps.
Commit 3d42f1ddc47a ("vgaarb: Keep adding VGA device in queue") assumes
the first device is an integrated GPU. However, on AMD platforms an
integrated GPU can have higher PCI device number than a discrete GPU.
Integrated GPU on ACPI platform generally has _DOD and _DOS method, so
use that as predicate to find integrated GPU. If the new strategy
doesn't work, fallback to use the first device as boot VGA.
