Only one --host exists at ./build-modules, since that can select the host
kernel, which is independent from the toolchain.
Document that user mode simulation stopped working.
This is a squash commit, the unsquashed development went through many
unstable phases which would break bisects. The unsquashed branch is:

The main improvement of this release was to greatly generalize the testing system.
The key addition was cli_function.py, which allows scripts such as ./run to
be transparently called either from Python or from the command line.
New tests scripts were created using this improved framework: test-baremetal
and test-user-mode.
We were lazy to port some of less important tests to the new setup, TODO's were
added, and we need comes they will be fixed. Getting started is however sacred
as usual and should work.
Other changes include:
- gem5: update to 7fa4c946386e7207ad5859e8ade0bbfc14000d91
- run: --tmux-args implies --tmux
- run: add --userland-args to make userland arguments across QEMU and gem5
Get rid of --userland-before as a consequence.
- bring initrd and initramfs back to life
- build-userland: create --static to make build a bit easier
- gem5: --gem5-worktree also set --gem5-build-id
- remove --gem5, use --emulator gem5 everywhere
Allow passing --emulator multiple times for transparent tests selection
just like --arch.
- test-userland: allow selecting just a few tests
- linux: update to v4.20
- buildroot: update to 2018.08
The main motivation for this was to fix the build for Ubuntu 18.10, which
has glibc 2.28, which broke the 2018.05 build at the m4-host package with:
#error "Please port gnulib fseeko.c to your platform!
- getvar --type input
- failed xen attempt, refactor timer, failed svc attempt, aarch64 use gicv3
- build-doc: exit 1 on error, add to release testing
- build: add --apt option to make things easier on other distros
- build-linux: --no-modules-install
Create a test for it under interactive/assert_fail.c
Move prompt under interactive
Create baremetal/arch/aarch64/c_from_as.S as an example of calling C
functions from assembly.
This way we group key value arguments: e.g.:
make \
-j 8 \
all
instead of:
make \
-j \
8 \
all
and reach CLI nirvana, while also subtly breaking several commands due to
lack of testing.
This will allow for other types of root filesystems that don't rely on Buildroot
to be added and used in the future.
Propagate --verbose on all build scripts to see full GCC commands.
build-all: allow for neat subsets
also 9p share rootfs_overlay. TODO document.
The update is required to include 3c3ca64b5f0dd9eef7b1ce1c65cc6e8e9147dd38
otherwise baremetal does not on VExpress.
baremetal: create a baremetal setup with crosstool-ng
buildroot: improve directory location: move out/dl inside
out/buildroot/download, and add a new out/buildroot/build level
tagline: generalize, deliver more value than howto, since now howtos
are starting to multiply
rename all top scripts to separate words with hyphen more consistently,
e.g. run-gdb instead of rungdb
getvar: list all variables
gem5: make m5out section to focus all releated information at
Prevent m5term Text file busy when rebuilding gem5 while it is running.
