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.
This is cleaner as it removes yet another .gitignore rule and allows
for one command per arch.
This was prompted by the recent Docker patch creating files as root,
which then breaks future host runs.
Also separate all arguments by newlines. This:
- makes it much easier to minimize when reporting QEMU bugs
- shows the full command on the screen despite line wrapping being turned off
by one of the annoying emulators, to be investigated.
The commands are not yet pristine, because:
- there are some leading spaces
- options not sorted
but it is already a huge improvement, and those operations are now be easy from Vim.
The general strategy is:
- end every variable containing a command with a newline
- when expanding such variables, don't add an extra newline
Most of it was present inside buildroot/output.* and the rest scattered
on top level.
This came about for the n-th time when we were reviewing QEMU trace file
locations.
On one hand, it would be cool to have per arch traces.
This made buildroot/output.${arch}~/ a natural choice.
But on the other, those traces have nothing to do with Buildroot,
and could potentially interfere with Buildroot build files.
It also feels nicer to have buildroot/ pristine source code only,
and keep all output under a single directory out/
Otherwise it was getting messy to distinguish between trace-events
and trace-<pid> in the .gitignore.
Now only the latest trace will be kept, with a fixed name.
This lead to a re-factoring of count boot instructions, since trace2line
relies on the same tracing mechanism.
Also, now that we have common factored, I've decided to put the traces on
the out dir, to concentrate all outputs in a single place, and allow
easy switching between archs.
Don't pass -e on checkpoint restore.
Add benchmarks to how much GEM5 is slower than QEMU.
Rename Kernel boot command line arguments to match kernel docs name.
Document how to pass extra options to GEM5.
Start listing interesting benchmarks to run on GEM5.
Add an openmp hello world.
Semi automated conversion, in part because Pandoc is kind of buggy for adoc:
Some of the commands were along the lines:
for f in *.md; do pandoc --atx-headers --base-header-level=3 -o ${f%.md}.adoc --wrap=none $f; done
sed -Ei '/\[\[.*\]\]/d' *.adoc
while read -r f; do cat $f; echo; done <f >g
