This series brings basic setup; starts a test's C entry point, main(),
and printf, exit, and malloc work. Three more series should follow this
one which must bring; vector support, mmu support, and smp support, at
which point I believe the framework could just evolve with the creation
of unit tests.
Tested on TCG and a P8 kvm_pr machine. I'm looking forward to hearing
more testing feedback from others. Maybe I should have added an RFT.
v3:
Paolo's comments:
- got rid of zero-sized files
Thomas' review comments:
- remove useless casts in needed cast adding patch
- got rid of build_romfs building (and committing a binary), just
offset the rom binary by 256 bytes now
- added a better error message for a -smp N, N > NR_CPUS user error
- got rid of infinite loop with broken rtas-poweroff
- one r-b (wasn't sure the "looks good"'s counted, so didn't add more)
Laurent's testing led me to
- fix a problem on kvm_pr with broken sc1
- fix handling of memory regions, expect more than one
- and a fix to DT code so that works
Additionally:
- new patches
- cscope: ppc64 needs to look in lib/powerpc/asm too,
and arm64 in lib/arm/asm
- handle memory regions better also for arm
- a misc trivial fix for arm...
- align toc to 256 bytes for later gcc
v2:
Besides rebasing on latest master, v2 addresses all of David's comments
- assembler cleanup
- jump into the RTAS blob we get from DT, instead of reproducing it
- don't store the RTAS root node, always hunt it down
We still haven't addressed debug-exit. Plugging chr-testdev into an spapr
vty is probably what we should investigate first (as was suggested by Alex
Graf under the v1 review). For now we keep the hack from v1, but simplified.
