* Export a (machine dependent) kernel variable bootdev asLuigi Rizzo2002-03-101-0/+51
| | | | | | | | | | | | | | | | | | | | | | | | | machdep.guessed_bootdev, and add code to sysctl to parse its value and give a (not necessarily correct) name to the device we booted from (the main motivation for this code is to use the info in the PicoBSD boot scripts, and the impact on the kernel is minimal). NOTE: the information available in bootdev is not always reliable, so you should not trust it too much. The parsing code is the same as in boot2.c, and cannot cover all cases -- as it is, it seems to work fine with floppies and IDE disks recognised by the BIOS. It _should_ work as well with SCSI disks recognised by the BIOS. Booting from a CDROM in floppy emulation will return /dev/fd0 (because this is what the BIOS tells us). Booting off the network (e.g. with etherboot) leaves bootdev unset so the value will be printed as "invalid (0xffffffff)". Finally, this feature might go away at some point, hopefully when we have a more reliable way to get the same information. MFC-after: 5 days Notes: svn path=/head/; revision=92018

| | | | | | | | | | | | | | | | | | a special file on the command line, eg: sysctl kern.dumpdev=/dev/ad1s1b In parse(), when a value is given for a CTLTYPE_QUAD variable, newval and newsize erroneously fail to be set because of an early "break". show_var() contains code that duplicates the functionality of the oidfmt() function.

* Add code to export and print the description associated to sysctlLuigi Rizzo2001-12-161-4/+16
| | | | | | | | | | | | | | | | | | | variables. Use the -d flag in sysctl(8) to see this information. Possible extensions to sysctl: + report variables that do not have a description + given a name, report the oid it maps to. Note to developers: have a look at your code, there are a number of variables which do not have a description. Note to developers: do we want this in 4.5 ? It is a very small change and very useful for documentation purposes. Suggested by: Orion Hodson Notes: svn path=/head/; revision=88006
* Implement -e option. It modifies the output produced by sysctl(8) inAnton Berezin2001-10-301-11/+19
| | | | | | | | | | | | | | such a way that the name and the value of the variable(s) are separated with `=' instead of the usual `: '. This is useful for producing output that can be fed back to the sysctl utility (pasted to sysctl.conf, for example).
