[PATCH 00/12] Q35 PCI host fixes and QOM cleanup
Posted by Bernhard Beschow 1 year, 2 months ago 
This series mostly cleans up QOM-related initialization code. It also performs
some modernization and fixing.

The first patch originates from "PC and ICH9 clanups" series [1] which has been
dropped in v3 in favor of another series [2]. Review comments in [2] suggest it
needs more work, so bring the patch back here.

Patch 2 fixes a clangd warning and patch 3 modernizes usage of the memory API.

Patches 4-9 clean up initialization code.

The last four patches also clean up initialization code with the last patch
doing the actual cleanup.

Based-on: <20230213162004.2797-1-shentey@gmail.com>
         "[PATCH v4 0/9] PC cleanups"

Testing done:
* `make check`
* `make check-avocado`
* `qemu-system-x86_64 -M q35 -m 2G -cdrom \
     manjaro-kde-21.3.2-220704-linux515.iso`

sent some comments. Philippe was reviewing related patches maybe
he wants to poke at these too.

what's the warning? commit log says nothing about it.
