* pkgbase: Create a FreeBSD-utilities package and make it the default oneEmmanuel Vadot2019-09-051-1/+0
| | | | | | | | | | | | | The default package use to be FreeBSD-runtime but it should only contain binaries and libs enough to boot to single user and repair the system, it is also very handy to have a package that can be tranform to a small mfsroot. So create a new package named FreeBSD-utilities and make it the default one. Also move a few binaries and lib into this package when it make sense.

* Create devctl freeze/thaw.Warner Losh2018-08-233-1/+33
| | | | | | | | | | | | This adds it to devctl, libdevctl, defines the two IOCTLs and implements the kernel bits. causes any new drivers that are added via kldload to be deferred until a 'thaw' comes in. These do not stack: it is an error to freeze while frozen, or thaw while thawed. Differential Revision: https://reviews.freebsd.org/D16735 Notes: svn path=/head/; revision=338233

* Implement 'devctl clear driver' to undo a previous 'devctl set driver'.John Baldwin2016-08-293-3/+51
| | | | | | | | | | | | | | | Add a new 'clear driver' command for devctl along with the accompanying ioctl and devctl_clear_driver() library routine to reset a device to use a wildcard devclass instead of a fixed devclass. This can be used to undo a previous 'set driver' command. After the device's name has been reset to permit wildcard names, it is reprobed so that it can attach to newly-available (to it) device drivers.

* Add 'devctl delete' that calls device_delete_child().John Baldwin2016-04-273-2/+36
| | | | | | | | | | | | | | | | 'devctl delete' can be used to delete a device that is no longer present. As an anti-foot-shooting measure, 'delete' will not delete a device unless it's parent bus says it is no longer present. This can be overridden by passing the force ('-f') flag. Note that this command should be used with care. If a device is deleted that is actually present it can't be resurrected unless the parent bus device's driver supports rescans.

* Add a new rescan method to the bus interface.John Baldwin2016-04-273-2/+28
| | | | | | | | | | | The BUS_RESCAN() method rescans a single bus device checking for devices that have been added or removed from the bus.

* META MODE: Update dependencies with 'the-lot' and add missing directories.Bryan Drewery2015-12-011-0/+18
| | | | | | | | | | | | | | | | | This is not properly respecting WITHOUT or ARCH dependencies in target/. Doing so requires a massive effort to rework targets/ to do so. A better approach will be to either include the SUBDIR Makefiles directly and map to DIRDEPS or just dynamically lookup the SUBDIR. These lose the benefit of having a userland/lib, userland/libexec, etc, though and results in a massive package. The current implementation of targets/ is very unmaintainable. Currently rescue/rescue and sys/modules are still not connected. Sponsored by: EMC / Isilon Storage Division Notes: svn path=/head/; revision=291563
* Add a new device control utility for new-bus devices called devctl. ThisJohn Baldwin2015-02-064-0/+469
allows the user to request administrative changes to individual devices such as attach or detaching drivers or disabling and re-enabling devices. - Add a new /dev/devctl2 character device which uses ioctls for device requests. The ioctls use a common 'struct devreq' which is somewhat similar to 'struct ifreq'. - The ioctls identify the device to operate on via a string. This string can either by the device's name, or it can be a bus-specific address. (For unattached devices, a bus address is the only way to locate a device.) Bus drivers register an eventhandler to claim unrecognized device names that the driver recognizes as a valid address. Two buses currently support addresses: ACPI recognizes any device in the ACPI namespace via its full path starting with "\" and the PCI bus driver recognizes an address specification of 'pci[<domain>:]<bus>:<slot>:<func>' (identical to the PCI selector strings supported by pciconf). - To make it easier to cut and paste, change the PnP location string in the PCI bus driver to output a full PCI selector string rather than 'slot=<slot> function=<func>'. - Add a devctl(3) interface in libdevctl which provides a wrapper around the ioctls and is the preferred interface for other userland code. - Add a devctl(8) program which is a simple wrapper around the requests supported by devctl(3). - Add a device_is_suspended() function to check DF_SUSPENDED. - Add a resource_unset_value() function that can be used to remove a hint from the kernel environment. This is used to clear a hint.<driver>.<unit>.disabled hint when re-enabling a boot-time disabled device.
