I think the reservation hints should be a absolute number, not a increment. i.e. if qemu suggests to reserve three extra bus numbers seabios should reserve three, no matter whenever there are zero, one, two or three child busses present. And I guess seabios should interpret that as minimum, so in case it finds five child busses it will allocate five bus numbers of course ... Same with the other limit hints. If the hint says to allocate 16M, and existing device bars sum up to 4M, allocate 16M (and therefore leave 12M address space for hotplug). If the device bars sum up to 32M, allocate that. While being at it: I have my doubts the capability struct layout (which mimics register layout) buys us that much, seabios wouldn't blindly copy over the values anyway. Having regular u32 fields looks more useful to me. cheers, Gerd

[RFC PATCH 0/2] Allow RedHat PCI bridges reserve more buses than necessary during init
by Aleksandr Bezzubikov 24 Jul '17

24 Jul '17

Now PCI bridges (and PCIE root port too) get a bus range number in system init, basing on currently plugged devices. That's why when one wants to hotplug another bridge, it needs his child bus, which the parent is unable to provide. The suggested workaround is to have vendor-specific capability in RedHat generic pcie-root-port that contains number of additional bus to reserve on BIOS PCI init.

Indeed, SeeBIOS does not reserve IO ports in this case, but Linux kernel still decides ""it knows better" and tries to allocate IO resources anyway. It does not affect the "modern" virtio-net devices because they don't need IO ports anyway. One way to work around the error message is to have the PCIe Root Port have the corresponding IO headers read-only since IO support is optional.

By the way, any ideas on how to avoid 'bus overstealing' would be greatly appreciated. Static BIOS variable isn't applicable since its value isn't saved across reboots. 2017-07-23 19:43 GMT+03:00 Alexander Bezzubikov <zuban32s(a)gmail.com>: > 2017-07-23 5:49 GMT+03:00 Michael S.
