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
Fixes Linux kernel boot on arm and aarch64 due to:
d84a0714220ffcc10eed0530ec01ed1a01a4ad4b Was failing with:
/build/ARM/cpu/simple/atomic.cc:377: virtual Fault AtomicSimpleCPU::readMem(Addr, uint8_t*, unsigned int, Request::Flags): Assertion
-`!pkt.isError()' failed
Otherwise, checking out branches is too insane, as it does not
update the worktrees, even though the gem5/gem5 module was updated.
gem5: expose build types, document debug builds.
simultaneous runs: store stdout and stderr on a file to allow running
all from a single terminal on the background cleanly.
Automatically pick up packages from under packages/ into BR2_EXTERNAL.
Move many subdirectory READMEs into the toplevel and link to toplevel from those subreadmes instead.
CXX='ccache c++' does not work, CXX=/my/path/to/ccache/wrapper/c++
does not work, the only thing that works it to put it in your PATH.
I would rather put a wrapper that forwards to ccache in this repo to
avoid the external host dependency:
#!/usr/bin/env bash
ccache c++ "$@"
but then that script has to remove its directory from PATH or else
infinite recursion, and I have no patience to code that.
I considered using the ccache from Buildroot, but it does not setup the
nice /usr/lib PATH, so I gave up on that as well.
Fix gem5/build wrong path for dd swapfile. Put it under out/ while we are at it
now that we have out of tree builds.
Allow seq_id larger than 7: broke previously because 08 is not valid octal.
Use timeout --foreground to allow killing scons
Don't upload results by default, too insane.
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.
Document that X11 mouse is not moving.
Convert x='' to x= on all scripts, and also fix case ;; indentations.
Add dummy value to QEMU's -trace enable= to prevent warning.
Expand built-in package choice rationale.
