Allocate resources from the parent device for decoded physical address ranges. When child resources suballocated from rman's are mapped, translate those mapping requests into a mapping request of the associated physical address range in a bus_map_resource method. While here, convert generic_pcie_rman to a bus_get_rman method and use bus_generic_rman_* for operations on child resources. Factor out a generic_pcie_containing_range to share logic between bus_translate_resource and bus_*map_resource. Reviewed by: imp Differential Revision: https://reviews.freebsd.org/D43894 |

FreeBSD Kernel Source:
This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.
Kernel configuration files are located in the conf/ subdirectory of each
architecture. GENERIC is the configuration used in release builds. NOTES
contains documentation of all possible entries. LINT is a compile-only
configuration used to maximize build coverage and detect regressions.
Documentation:
Source code documentation is maintained in a set of man pages, under section 9.
These pages are located in share/man/man9, from the
top-level of the src tree. Consult intro(9)
for an overview of existing pages.
Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
