eee6c825c3 qemu: allow turning -O0 debug build on or off, use -O0 by default
OMG, I was wasting time in ARM all along!!!

4a4407e7a8 qemu: update to d8dae268c0a3e4e361002aca3b382fedd77f2567
Now on top of QEMU v4.0.0.

Ha, everything just worked. That wasn't fun!

da900a579c LKMC v3.0
This is a squash commit, the unsquashed development went through many
unstable phases which would break bisects. The unsquashed branch is:
https://github.com/cirosantilli/linux-kernel-module-cheat/tree/v3.0-unsquash

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

8fb9db3931 manually encode newlines on all printed commands
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.

4f47491482 userland: make uber awesome with --baremetal-like executable resolution 2018-10-30 22:00:02 +00:00
a29b5a41fb gem5: expose syscall emulation with --user
Then also expose QEMU user mode with --user. Docs not perfect yet,
would require a build alternative for userland/ for -static and or
passing options before the QEMU userland executable with a new CLI.

bc73cebff1 Build the Linux kernel independently from Buildroot
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.

56738a1c70 lkmc v2-rc
Unsquashed version at v2-rc-unsquashed, but that cannot be merged as it
breaks bisects at several points. All bugs will not bisect to this
humongous change.

It all started with a conversion of the Bash scripts to Python, mainly
because I couldn't stand not being able to properly use --options for
run which has a million options.

Then since that required a full testing, I decided to do all the
refactorings that I had in mind at once, and so I did and it became
v2-rc.

This is the largest patch I have ever done! OMG a few weeks of extra time.
I'm never writing a Bash script for anything that starts getting big again.

Some of the features are:

* separate build-qemu and build-gem5 commands
* common: convert scripts to python. Add --option for everything
* rename build to build-buildroot now that we are splitting all the build
  commands, Linux kernel to follow
* move all git submodules to submodules/ and all buildroot packages to
  packages/
* refactor the out/ structure. Keep projects on toplevel, because guest
  projects separate archs and host ones don't, making a toplevel arch wrong
* do-release: rename to just release

* run: add --terminal and explain gem5 pdb
* just track the lvimrc
* store CLI kernel config fragment inside buildlroot to avoid conflicts
* gem5: document m5 initparam
* readme: make a bunch of things awesomer
* readme: fix broken refs
* parsec-benchmark: update to 75d55ac446a43c47efb1044844a108c6c330184c
  Could not fetch otherwise.
