[Qemu-devel] [PATCH for-1.5 v2 00/20] QOM realize for ISA, part 1

[Qemu-devel] [PATCH for-1.5 v2 00/20] QOM realize for ISA, part 1

[Andreas Färber]

Hello,

Here is my next batch of QOM realize patches.

These mostly introduce QOM cast macros for ISADevice-derived types,
so should hopefully be safe to apply for 1.5.

The mc146818 patch is also queued on qom-cpu and reused for CPU hot-add.

Available from:
https://github.com/afaerber/qemu-cpu/commits/realize-isa.cleanup.v2
git://github.com/afaerber/qemu-cpu.git realize-isa.cleanup.v2

Regards,
Andreas

v1 -> v2:
* QOM realize infrastructure was split off and applied.
* isa-debugcon was QOM'ified.
* Rebased onto multiple hw/ reorganizations.
* Renamed M48T59_ISA() to ISA_M48T59() to match dominant specific <- base scheme.
* Deferred ISADevice::init removal to follow-up series.

[Qemu-devel] [PATCH for-1.5 v2 17/20] vga-isa: QOM'ify ISA VGA

[Andreas Färber]

Introduce type constant and cast macro to obsolete DO_UPCAST() and
container_of(). Prepares for ISA realizefn.

Unify function naming scheme while at it.
