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 where \_SB_.LSB1 is a container, it just did nothing. Do we need to support this operation ? Thanks. :)
Thanks Yinghai
