[Qemu-devel] [PATCH 0/7] machvirt dynamic sysbus device instantiation |
Date: |

This RFC enables machvirt to dynamically instantiate sysbus devices
from command line.
the RFC relies on
- Alex Graf's "Dynamic sysbus device allocation support"
http://lists.gnu.org/archive/html/qemu-ppc/2014-07/msg00047.html
On top of sysbus device Alex' modifications, the RFC reuses his code
developped in PPC e500.c. First that code was moved in a
separate module (hw/misc/physical_devices) and then machvirt was
adapted to call those helper routines.
It is also proposed to add a new method in SysBysDeviceClass, named
fdt_add_node, whose role is to create the device tree node. It is
meant to be specialized by devices that support dynamic instantiation.
In practice there is a need for 2 specializations: one for the device,
and one for the board. It is assumed the provision for PlatformDevtreeData
enables the board adaptation. However, this later may need to be
augmented: typically some clock handles may need to be provided.
Best Regards
Eric
