Hi,
I tried v11 patches. This version seems to fix the problem I
reported against previous version.
I have no objection against the idea of resource allocation
changes for PCI express hotplug slots.
thanks
But I still have concern about changing resource allocation for
other than PCI express hotplug slots. For example, some hotplug
controller other than PCI express can have multiple slots under
the same bus. If some hotplug slots are occupied and the others
are empty at the boot time, I think your code try to shrink the
bus resources for hotplug slots allocated by BIOS. It would break
the hot-add on the empty slots due to the resource allocation
failure.
no,
it will not touch bridge resources that already assigned by BIOS except
some bridge resource is not big enough. and get big one for them.
Ok, I understood that if the BIOS assigns enough resources to the
bridge, it has no impact.
One question. I thought your patch shrinks the bridge resource to
allocate enough resource for sibling bridge. But it actually doesn't.
Right?
It would be appreciated if you update the patch description about
the problem and how to fix/improbe it.
Thanks,
Kenji Kaneshige
