Hey, This is largely a resend to get some more attention. I've attempted to clean up and expand on the commit message of the first commit because the bug is a bit of a nightmare to explain and follow. There's a lot more information on the first commit in the original thread here[1] including instructions on how to reproduce it in QEMU. The second patch fixes an unrelated bug, with similar symptoms, in the same code. It was a lot easier to debug and the reasoning should hopefully be easier to follow, but I don't think it was reviewed much during the first posting due to the nightmare in the first patch. Thanks, Logan [1] https://lore.kernel.org/lkml/de3e34d8-2ac3-e89b-30f1-a18826ce5d7d@xxxxxxxxxxxx/T/#m96ba95de4678146ed46b602e8bfd6ac08a588fa2 Logan Gunthorpe (2): PCI: Prevent 64-bit resources from being counted in 32-bit bridge region PCI: Fix disabling of bridge BARs when assigning bus resources drivers/pci/setup-bus.c | 24 ++++++++++++++---------- 1 file changed, 14 insertions(+), 10 deletions(-) -- 2.20.1
