Hi Len,
I hope this isn't too late for the .31 merge window. If so, no big deal;
this patchset isn't urgent, it's just a nice cleanup that was inspired
from investigating the recent bug in acpi_pci_bind() (fixed by dacd254).
This patch series eliminates static boot-time binding of ACPI
and PCI devices, and introduces an API to perform this lookup
during runtime.
This change has the following advantages:
- eliminates struct acpi_device vs struct pci_dev lifetime issues
- lays groundwork for eliminating .bind/.unbind from acpi_device_ops
- lays more groundwork for eliminating .start from acpi_device_ops
and thus simplifying ACPI drivers
- whacks out a lot of code
This patchset is based on lenb/test (66c74fa1d4), and has been boot
tested on ia64 and x86. I also performed physical PCI hotplug tests
using acpiphp on ia64. I do not have an acpiphp-capable x86 platform.
I didn't test the changes in the video driver either, as I don't have
the hardware.
v1 -> v2
- rearrange series into a more logical order
- much simpler acpi_is_root_bridge() implementation
- no longer export acpi_pci_find_root()
- no longer leak memory in acpi_get_pci_dev()
- no longer leak references in acpi_pci_unbind/acpi_pci_bind
- convert video driver to use acpi_get_pci_dev()
- kill off acpi_get_physical_pci_device()
- incorporate Bjorn's other comments. :)
