I'm just not sure if that can be done for pre-6.15 kernels as touching the resource fitting / assignment algorithm is pretty precarious. Steven, could you try with 6.15-rc based kernels with that min bridge window patch + pci=3Drealloc,min_bridge_window? Please also include the reset debu= gging patch I just attached and dyndbg on the command line. There are number of things in the 6.14 log I don't understand and I suspect I might have fixed = at least one of those in my recent changes to the resource fitting algorithm. The failure to shrink bridge window size for 0000:22:02 from 0x500000 to 0x100000 as IOV resources should be optional, is particularly perplexing. Instead, the non-64bit windows vanish from many bridges after bridge windows are released, which could be due to improper reset of a resource after one = of the steps which the later steps fail to undo for some reason. --=20 You may reply to this email to add a comment.
