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
gem5 cache automate benchmarks, and remove results that were scattered all over.
Move console fun under linux kernel section, since not important enough
for getting started.
Set arch x86_64 by default through common on all scripts.
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.
Get rid of br2_parsec, since there are just too many possible variations on that file.
Blow up the gem5 vs qemu table to make it saner, add missing aarch64 entries.
Make sections titles describing number of cores and memory size emulator agnostic.
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/
