From c57e2a3047ba7651aae205b34fe701c3312ca5e9 Mon Sep 17 00:00:00 2001 From: hauke Date: Sat, 24 Nov 2012 20:24:27 +0000 Subject: [PATCH] brcm47xx: watchdog: deactivate NOWAYOUT. In the old configuration the SoC issued a reboot if the watchdog was killed also if it was kill with TERM and not KILL. This will fix #11724. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@34324 3c298f89-4303-0410-b956-a3cf2f4a3e73 --- target/linux/brcm47xx/config-3.6 | 1 - ...cm47xx_wdt.c-convert-to-watchdog-core-api.patch | 23 ++++++++++++++-------- ...atchdog-bcm47xx_wdt.c-use-platform-device.patch | 12 +++++------ ...watchdog-bcm47xx_wdt.c-rename-ops-methods.patch | 14 ++++++------- ...m47xx_wdt.c-rename-wdt_timeout-to-timeout.patch | 6 +++--- ...544-watchdog-bcm47xx_wdt.c-add-hard-timer.patch | 6 +++--- 6 files changed, 34 insertions(+), 28 deletions(-) diff --git a/target/linux/brcm47xx/config-3.6 b/target/linux/brcm47xx/config-3.6 index 4859a5b6d1..478ba847c5 100644 --- a/target/linux/brcm47xx/config-3.6 +++ b/target/linux/brcm47xx/config-3.6 @@ -145,5 +145,4 @@ CONFIG_USB_ARCH_HAS_XHCI=y # CONFIG_USB_HCD_SSB is not set CONFIG_USB_SUPPORT=y CONFIG_WATCHDOG_CORE=y -CONFIG_WATCHDOG_NOWAYOUT=y CONFIG_ZONE_DMA_FLAG=0 diff --git a/target/linux/brcm47xx/patches-3.6/540-watchdog-bcm47xx_wdt.c-convert-to-watchdog-core-api.patch b/target/linux/brcm47xx/patches-3.6/540-watchdog-bcm47xx_wdt.c-convert-to-watchdog-core-api.patch index 7ac56387fe..21136c0e3c 100644 --- a/target/linux/brcm47xx/patches-3.6/540-watchdog-bcm47xx_wdt.c-convert-to-watchdog-core-api.patch +++ b/target/linux/brcm47xx/patches-3.6/540-watchdog-bcm47xx_wdt.c-convert-to-watchdog-core-api.patch @@ -26,16 +26,23 @@ #include #include #include -@@ -48,8 +45,6 @@ MODULE_PARM_DESC(nowayout, +@@ -41,15 +38,11 @@ module_param(wdt_time, int, 0); + MODULE_PARM_DESC(wdt_time, "Watchdog time in seconds.
