Hey, This is another resend to get some more attention. Nothing has changed since v2. For the first patch, there's a lot more information 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@deltatee.com/T/#m96ba95de4678146ed46b602e8bfd6ac08a588fa2 -- Changes in v3: * Rebased onto v5.2-rc2 (no changes) Changes in v2: * Rebased onto v5.1-rc6 (no changes) * Reworked the commit message in the first commit to try and explain it better. -- 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
