* watchdog: Add kernel-doc for wdt_set_timeout()Yang Li2024-03-031-0/+4
| | | | | | | | | | | | The wdt_set_timeout function lacked a complete kernel-doc description. This patch adds missing parameter and return value descriptions in accordance with kernel-doc standards.

* watchdog: it87_wdt: Keep WDTCTRL bit 3 unmodified for IT8784/IT8786Werner Fischer2023-12-171-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | WDTCTRL bit 3 sets the mode choice for the clock input of IT8784/IT8786. Some motherboards require this bit to be set to 1 (= PCICLK mode), otherwise the watchdog functionality gets broken. The BIOS of those motherboards sets WDTCTRL bit 3 already to 1. Instead of setting all bits of WDTCTRL to 0 by writing 0x00 to it, keep bit 3 of it unchanged for IT8784/IT8786 chips. In this way, bit 3 keeps the status as set by the BIOS of the motherboard. Watchdog tests have been successful with this patch with the following systems: IT8784: Thomas-Krenn LES plus v2 (YANLING YL-KBRL2 V2) IT8786: Thomas-Krenn LES plus v3 (YANLING YL-CLU L2) IT8786: Thomas-Krenn LES network 6L v2 (YANLING YL-CLU6L) Link: https://lore.kernel.org/all/140b264d-341f-465b-8715-dacfe84b3f71@roeck-us.net/ Signed-off-by: Werner Fischer <devlists@wefi.net> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Link: https://lore.kernel.org/r/20231213094525.11849-4-devlists@wefi.net Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@linux-watchdog.org>

* watchdog: it87_wdt: Work around non-working CIR interruptsMarc van der Wal2014-03-311-10/+31
| | | | | | | | | | | | | | | | | | | | | | | | On some hardware platforms, the it87_wdt watchdog resets the machine despite the watchdog daemon running and writing to /dev/watchdog. This is due to Consumer IR buffer underrun interrupts being used as triggers to reset the timer. On some buggy hardware implementations such as the iEi AFL-12A-N270 single-board computer, this method does not work. However, resetting the timer by writing its original timeout value in its configuration register over and over again suppresses the unwanted reboots. Add a module option (nocir), 0 by default in order not to break existing setups. Setting it to 1 enables the workaround. Fixes bug #42801 <https://bugzilla.kernel.org/show_bug.cgi?id=42801>.

* watchdog: Get rid of MODULE_ALIAS_MISCDEV statementsJean Delvare2013-11-171-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR) and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements. Either the device is enumerated and the driver already has a module alias (e.g. PCI, USB etc.) that will get the right driver loaded automatically. Or the device is not enumerated and loading its driver will lead to more or less intrusive hardware poking. Such hardware poking should be limited to a bare minimum, so the user should really decide which drivers should be tried and in what order. Trying them all in arbitrary order can't do any good. On top of that, loading that many drivers at once bloats the kernel log. Also many drivers will stay loaded afterward, bloating the output of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets loaded as a dependency) can't even be unloaded! If defining char-major-10-130 is needed then it should happen in user-space.

I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that.
