[kvm-unit-tests PATCH v4 00/17] ppc64: initial drop

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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, and Laurent has tested it on
both a PowerMac G5 (kvm_pr) and a kvm_hv machine. I'm looking forward
to hearing more testing feedback from others though.

v4:
 - check for H_PRIVILEGE in broken sc1 probe [David]
 - rename rtas' lock from lock to rtas_lock [Thomas]
 - rtas: should only iterate to size/4 [drew]
 - add powerpc/.gitignore (ignore boot_rom.bin) [drew]

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.
