Currently the xmon debugger is set only via kernel boot command-line. It's disabled by default, and can be enabled with "xmon=on" on the command-line. Also, xmon may be accessed via sysrq mechanism. But we cannot enable/disable xmon in runtime, it needs kernel reload. This patch introduces a debugfs entry for xmon, allowing user to query its current state and change it if desired. Basically, the "xmon" file to read from/write to is under the debugfs mount point, on powerpc directory. It's a simple attribute, value 0 meaning xmon is disabled and value 1 the opposite. Writing these states to the file will take immediate effect in the debugger. Signed-off-by: Guilherme G. Piccoli <gpiccoli@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> |
