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. Reviewed by: imp (parts) Requested by: imp (changing PCI location string) Relnotes: yes |
