no, we don't need that.
after closely looking, it seems we can dump acpi_root_bridge.
please check if attached patch could work with container path.
Hi Yinghai,
Your patch seems working well.
BTW, I actually found that the two lists, acpi_root_bridge and
acpi_pci_roots in drivers/acpi/pci_root.c were similar, except
your acpi_root_bridge included PNP0A08.
In the beginning, I thought you would use it in some other situations,
and now it is clear that it can be removed.
Thanks. :)
And also, I have another 2 questions, maybe you can help me.
1) Do we need to put PNP0A08 into acpi_pci_roots ?
2) In container_notify_cb(), when it got a ACPI_NOTIFY_EJECT_REQUEST
event, it doesn't do the hot-remove things.
I use your sci emulator patch to test it. I did the following thing:
echo echo "\_SB_.LSB1" > /sys/kernel/debug/acpi/sci_notify
==> echo "\_SB_.LSB1 3" > /sys/kernel/debug/acpi/sci_notify
where \_SB_.LSB1 is a container, it just did nothing.
Do we need to support this operation ?
Thanks. :)
Thanks
Yinghai
