When using mxs-auart based console, sometime we need the sysrq function to help debugging kernel. The sysrq code is basically there, this patch just simply enable it. Signed-off-by: Janusz Uzycki <j.uzycki@xxxxxxxxxxxxxx> --- Changes from v1 (the initial version of the patch): * the patch was extracted as indendent from my previous patchset "serial: mxs-auart: use mctrl_gpio helpers for handling modem signals (v2.2c)" "[PATCH 4/4] serial: mxs-auart: add sysrq support" * removed obvious comment about required order of SUPPORT_SYSRQ define and serial_core.h include The patch is resent as ready to apply. I resend it again because last time in conver letter I swapped subject with in-reply-to and the patch could be omited. This time I've added versioning and changelog. --- drivers/tty/serial/mxs-auart.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/tty/serial/mxs-auart.c b/drivers/tty/serial/mxs-auart.c index eafce41..e838e84 100644 --- a/drivers/tty/serial/mxs-auart.c +++ b/drivers/tty/serial/mxs-auart.c @@ -14,6 +14,10 @@ * http://www.gnu.org/copyleft/gpl.html */ +#if defined(CONFIG_SERIAL_MXS_AUART_CONSOLE) && defined(CONFIG_MAGIC_SYSRQ) +#define SUPPORT_SYSRQ +#endif + #include <linux/kernel.h> #include <linux/errno.h> #include <linux/init.h> -- 1.7.11.3 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
