ACPI Device() objects that do not have any device IDs available via the _HID or _CID methods. Without a device ID a device driver cannot attach to the device anyway. Namespace objects that are devices but not of type ACPI_TYPE_DEVICE are not affected. A few BIOSes have also attached a _CRS method to a PCI device to allocate resources that are not managed via a BAR. With the previous code those resources are allocated from acpi0 directly which can interfere with the new PCI-PCI bridge driver (since the PCI device in question may be behind a bridge and its resources should be allocated from that bridge's windows instead). The resources were also orphaned and and would end up associated with some other random device whose device_t reused the pointer of the original ACPI-enumerated device (after it was free'd by the ACPI PCI bus driver) in devinfo output which was confusing. If we want to handle _CRS on PCI devices we can adjust the ACPI PCI bus driver to do that in the future and associate the resources with the proper device object respecting PCI-PCI bridges, etc. Note that with this change the ACPI PCI bus driver no longer has to delete ACPI-enumerated device_t devices that mirror PCI devices since they should in general not exist. There are rare cases when a BIOS will give a PCI device a _HID (e.g. I've seen a PCI-ISA bridge given a _HID for a system resource device). In that case we leave both the ACPI and PCI-enumerated device_t objects around just as in the previous code. |

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. The ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables. The ``buildkernel'' and ``installkernel'' targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. Note: If you want to build and install the kernel with the ``buildkernel'' and ``installkernel'' targets, you might need to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
