It's been a loooong time since I posted v1 of this series, but thanks
to Thomas' poking, and even volunteering to help move v2 along, I've
finally picked it back up.
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
v2 didn't address debug-exit, and we still need a solution for that.
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 this v2 I just kept the hack from v1, but simplified it and
explicitly call it out as the hack that it is.
Additional known issues:
Latest F22 cross-compiler (gcc5 based) doesn't generate working
code with this series. I didn't try to debug. The 4.9 based compiler
I initially used on v1 works, so I reverted to that one.
Testing:
I only tested with qemu-system-ppc64 (latest) on x86_64 so far. I'll
try to get a machine to test with real hardware (and KVM) unless
someone (hi Thomas :-) beats me to it.
Standard cover-letter summary:
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.
