John Baldwin <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|New |In Progress --- Comment #4 from John Baldwin <[email protected]> --- >From what I could tell when I looked at this before for Dave, this appears to be an issue specific to linuxkpi used by the mlx5 driver. In particular, it uses bus_translate_resource in its wrapper for pci_resource_start and I had asked Dave to boot with an additional patch to try to trace what is going on there to see if it is getting the wrong answer. The mlx5 driver assumes that pci_resource_start gives a valid physical address it can pass to ioremap to create a memory mapping of the BAR. The patch with the debugging trace is here: https://reviews.freebsd.org/P632 -- You are receiving this mail because: You are the assignee for the bug.
