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.
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.
* gem5: M5_OVERRIDE_PY_SOURCE
As noted however, it is potentially too slow to be useful.
run: unify gem5 and qemu tracing under -T
readme: overhaul tracing documentation from what I've learnt from trace2line
gem5 requires armv7, and we learnt that the versatiledb we were using
was pre-v7.
We could have moved to -M vexpress-*, but in the end decided to go for
-M virt due to its simpliciy, and uniformity with aarch64.
platform_device: does not work anymore and was removed, since it was tied
to versatilepb.
We left a mention on the README and removed all in tree source. The QEMU
patch is still left as it was.
As a consequence, the linux tree had no other patches, and we now use
vanilla linux by default, which is a great thing for reproducibility.
Another consequence is the /poweroff.out works for arm -M virt,
and we removed all mentions of the problem.
