Name
kvar - modify RISC kernel variables in memory or on disk
Syntax
/usr/etc/kvar -r(b|w|l) [options] vmunix
/usr/etc/kvar -w(b|w|l) [options] vmunix
Description
The command allows you to read or write RISC kernel variables, either in the on-disk image of or the active in-memory image. The -r form
of the command does variable reads; the -w form does variable writes. The variable length qualifiers are: b (1 byte), w (word, or 2
bytes), and l (longword, or 4 bytes).
Variable contents are displayed in hexadecimal format.
Options
-a address Specifies the address of the kernel variable. Either the -a or -s option must be specified. The address is specified as
either a positive decimal or hexadecimal constant.
-k Instructs to use the in-memory image of The default is to use the on-disk copy.
-l Searches for a local symbol. The default is a global symbol search.
-o offset Adds an offset to the address (or address of the symbol name). The offset value is specified as either a positive decimal or
hexadecimal constant.
-s name Specifies the name of the kernel variable.
-v value Specifies the new value to be assigned by the -w form of The -v option is ignored if the -r form of is being used. The value
is specified as either a positive decimal or hexadecimal constant.
Restrictions
You must have appropriate file access permissions for (and for with the -k option).
The command is available only on RISC systems. For VAX systems, use to modify kernel variables.
Examples
This example reads the variable `udpcksum' from the running kernel image:
% kvar -k -rl -s udpcksum /vmunix
This example sets the `xyz' variable to zero in the running kernel image:
% kvar -k -wl -s xyz -v 0 /vmunix
This example sets the variable `xyz' to -1 in the on-disk image of making this value persistent across reboots:
% kvar -wl -s xyz -v 0xffffffff /vmunix
This example sets to zero 1 byte at offset 2 from address 0x80161a98 in the running kernel image:
% kvar -k -wb -o 2 -a 0x80161a98 /vmunix
