[Qemu-devel] [PATCH v2 0/7] Fix device introspection regressions

[Markus Armbruster]

QMP command device-list-properties regressed in 2.1: it can crash or
leave dangling pointers behind.

-device FOO,help regressed in 2.2: it no longer works for
non-pluggable devices.  I tried to fix that some time ago[*], but my
fix failed review.  This is my second, more comprehensive try.

PATCH 1,2 are preliminaries, PATCH 3 adds tests to demonstrate the
bugs, PATCH 4-6 fix them to a degree (see PATCH 5 for limitations),
and PATCH 7 cleans up.

[*] [PATCH] qdev: Make -device FOO,help help again when FOO is not
pluggable

v2:
* PATCH 1: New, made from old PATCH 7 and relevant Makefile parts of
  old PATCH 3, with a much improved commit message [Andreas]

* PATCH 6: Mark only the CPUs that are actually broken [Eduardo]

Markus Armbruster (7):
  tests: Fix how qom-test is run
  libqtest: Clean up unused QTestState member sigact_old
  libqtest: New hmp() & friends
  device-introspect-test: New, covering device introspection
  qmp: Fix device-list-properties not to crash for abstract device
  qdev: Protect device-list-properties against broken devices
  Revert "qdev: Use qdev_get_device_class() for -device <type>,help"
