The branch stable/14 has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=92991e8f8d319981c7f9b0ad1fc3855b6dfdfe3a commit 92991e8f8d319981c7f9b0ad1fc3855b6dfdfe3a Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2023-11-25 18:32:19 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2024-01-03 20:47:24 +0000 new-bus: Disable assertions for rman mismatches for activate/deactivate Bus drivers which use an rman to sub-divide a resource allocated from a parent bus should handle mapping requests (and activate/deactivate requests) for those sub-allocated resources by doing a subset mapping of the resource allocated from the parent (and then using this to handle activate/deactivate requests). However, not all bus drivers which use internal rmans (such as acpi(4) and pci_pci(4)) do that since not all nexus drivers support bus_map/unmap. Eventually bus drivers should be updated to do this properly at which point these assertions can be reenabled.
