|

The Magic SysRQ system works by registering key operations against a key op
|
||||
lookup table, which is defined in 'drivers/char/sysrq.c'. This key table has
|
||||
a number of operations registered into it at compile time, but is mutable,
|
||||
and 4 functions are exported for interface to it: __sysrq_lock_table,
|
||||
__sysrq_unlock_table, __sysrq_get_key_op, and __sysrq_put_key_op. The
|
||||
functions __sysrq_swap_key_ops and __sysrq_swap_key_ops_nolock are defined
|
||||
in the header itself, and the REGISTER and UNREGISTER macros are built from
|
||||
these. More complex (and dangerous!) manipulations of the table are possible
|
||||
using these functions, but you must be careful to always lock the table before
|
||||
you read or write from it, and to unlock it again when you are done. (And of
|
||||
course, to never ever leave an invalid pointer in the table). Null pointers in
|
||||
the table are always safe :)
|
||||
and 2 functions are exported for interface to it:
|
||||
register_sysrq_key and unregister_sysrq_key.
|
||||
Of course, never ever leave an invalid pointer in the table. I.e., when
|
||||
your module that called register_sysrq_key() exits, it must call
|
||||
unregister_sysrq_key() to clean up the sysrq key table entry that it used.
|
||||
Null pointers in the table are always safe. :)

||||
If for some reason you feel the need to call the handle_sysrq function from
