kldxref -- generate hints for the kernel loader SYNOPSIS
kldxref [-Rdv] [-f hintsfile] path ... DESCRIPTION
The kldxref utility is used to generate hint files which list modules, their version numbers, and the files that contain them. These hints are used by the kernel loader to determine where to find a particular KLD module. A separate hint file is generated for each directory listed on the command line that contains modules. If no hint records are generated for a particular directory, no hint file is created, and the preexisting hint file (if there was one in that directory) is removed. The following options are available: -R Recurse into subdirectories. -d Do not generate a hint file, but print module metadata on standard output. -f hintsfile Specify a different name for the hints files than linker.hints. -v Operate in verbose mode. EXAMPLES
To build hint files for both standard and add-on modules: kldxref /boot/kernel /boot/modules To build hint files for all installed kernels: kldxref -R /boot SEE ALSO

device.hints -- device resource hints DESCRIPTION
The device.hints file is read in by the boot loader(8) when the system is about to start, and its contents are passed to the kernel. It con- tains various variables to control the boot behavior of the kernel. These variables are typically ``device hints''. The file contains one variable per line. Lines starting with the '#' character are comments and are ignored by the boot loader. After the file is read by the boot loader, you may examine the variables with the show command, and may add a new variable, modify an exist- ing one, or delete a variable with the set and unset commands of the boot loader (see loader(8)). After the system has started, you can dump these variables with the kenv(1) command. DEVICE HINTS
Device hint variables are used by device drivers to set up the device. They are most often used by ISA device drivers to specify where the driver will probe for the relevant devices, and what resources it will attempt to use. A device hint line looks like: hint.driver.unit.keyword="value" where driver is the name of a device driver, unit is the unit number, and keyword is the keyword of the hint. The keyword may be: at specifies a bus to which the device is attached. port specifies the start address of I/O ports to be used by the device. portsize specifies the number of ports used by the device. irq is the interrupt line number to be used. drq is the DMA channel number. maddr specifies the physical memory address used by the device. msize specifies the physical memory size used by the device. flags sets various flag bits for the device. disabled can be set to "1" to disable the device. A device driver may require one or more hint lines with these keywords, and may accept other keywords not listed here, through resource_int_value(9). Consult individual device drivers' manual pages for available keywords and their possible values. FILES
/boot/device.hints Device resource hints file. /sys/ARCH/conf/GENERIC.hints Sample resource hints for the GENERIC kernel. /sys/ARCH/conf/NOTES Notes on the kernel configuration file and device resource hints. EXAMPLES
The following example sets up resources for the sio(4) driver on the ISA bus:"isa" hint.sio.0.port="0x3F8" hint.sio.0.flags="0x10" hint.sio.0.irq="4" The following example disables the ACPI driver: hint.acpi.0.disabled="1" SEE ALSO
