* bus_alloc_resource: Pass rid by value to BUS_ALLOC_RESOURCE DEVMETHODJohn Baldwin2025-12-094-9/+9
| | | | | | | | | The wrapper functions such as bus_alloc_resource_any() still support passing the rid by value or pointer, but the underlying implementation now passes by value. Reviewed by: imp Differential Revision: https://reviews.freebsd.org/D53402

* Retire unused non-PCI_RES_BUS codeJessica Clarke2024-07-181-18/+0
| | | | | | | | All architectures define PCI_RES_BUS unconditionally now that only NEW_PCIB is supported, so we no longer need the legacy code. Reviewed by: jhb, andrew Differential Revision: https://reviews.freebsd.org/D32955
* Retire non-NEW_PCIB code and remove config optionJessica Clarke2024-07-181-9/+9
| | | | | | | | | | | All architectures enable NEW_PCIB in DEFAULTS (arm being the most recent to do so in 121be555997b (arm: Set NEW_PCIB in DEFAULTS rather than a subset of kernel configs")), so it's time we removed the legacy code that no longer sees much testing and has a significant maintenance burden.

* Convert rman to use rman_res_t instead of u_longJustin Hibbits2016-01-272-6/+6
| | | | | | | | | | | | | | | | | | | | | | | Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long. This is step one in migrating rman to use uintmax_t for resources instead of u_long. Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API. This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.
