2025-06-01watchdog: iTCO_wdt: Update the heartbeat value after clamping timeoutZiyan Fu1-0/+1
When executing "modprobe iTCO_wdt heartbeat=700", the user-specified 'heartbeat' parameter exceeds the valid range, the driver clamps the timeout to default 30s but fails to update the logged 'heartbeat' value, resulting in misleading log output: iTCO_wdt iTCO_wdt: timeout value out of range, using 30 iTCO_wdt iTCO_wdt: initialized. heartbeat=700 sec (nowayout=0) After validating the range, update the 'heartbeat' value with the clamped timeout value to ensure that log messages accurately reflect the actual runtime parameters.

Add a driver for the Intel Over-Clocking Watchdog found in Intel Platform Controller (PCH) chipsets.

The optional SMCWD_GET_TIMELEFT command can be used to detect if the watchdog has already been started. See the implementation in OP-TEE secure OS [1]. At probe time, check if the watchdog is already started and then set WDOG_HW_RUNNING in the watchdog status. This will cause the watchdog framework to ping the watchdog until a userspace watchdog daemon takes over the control.

The hardware only supports timeouts slightly below 3mins, but by using max_hw_heartbeat_ms we can let the kernel take care of supporting larger timeouts than that requested from userspace. Switching to max_hw_heartbeat_ms also means our set_timeout function now needs to configure the hardware to the minimum of either the requested timeout (in seconds) or the maximum supported by the user (in seconds).

2025-05-24watchdog: Add the Watchdog Timer for the NXP S32 platformDaniel Lezcano3-0/+325
The S32 platform has several Watchdog Timer available and tied with a CPU. The SWT0 is the only one which directly asserts the reset line, other SWT require an external setup to configure the reset behavior which is not part of this change. As a side note, in the NXP documentation, the s32g2 and s32g3 reference manuals refer the watchdog as the 'Software Timer Watchdog' where the name can be misleading as it is actually a hardware watchdog. The maximum watchdog timeout value depends on the clock feeding the SWT counter which is 32bits wide. On the s32g274-rb2, the clock has a rate of 51MHz which result on 83 seconds maximum timeout. The timeout can be specified via the device tree with the usual existing bindings 'timeout-sec' or via the module param timeout. The watchdog can be loaded with the 'nowayout' option, preventing the watchdog to be stopped. The watchdog can be started at boot time with the 'early-enable' option, thus letting the watchdog framework to service the watchdog counter. The watchdog support the magic character to stop when the userspace releases the device.

2025-03-25watchdog: sunxi_wdt: Add support for Allwinner A523Andre Przywara1-0/+11
The Allwinner A523 SoC comes with a watchdog very similar to the ones in the previous Allwinner SoCs, but oddly enough moves the first half of its registers up by one word. Since we have different offsets for these registers across the other SoCs as well, this can simply be modelled by just stating the new offsets in our per-SoC struct. The rest of the IP is the same as in the D1, although the A523 moves its watchdog to a separate MMIO frame, so it's not embedded in the timer anymore. The driver can be ignorant of this, because the DT will take care of this. Add a new struct for the A523, specifying the SoC-specific details, and tie the new DT compatible string to it.

2025-03-09watchdog: aspeed: Update bootstatus handlingChin-Ting Kuo1-2/+79
The boot status in the watchdog device struct is updated during controller probe stage. Application layer can get the boot status through the command, cat /sys/class/watchdog/watchdogX/bootstatus. The bootstatus can be, WDIOF_CARDRESET => System is reset due to WDT timeout occurs. Others => Other reset events, e.g., power on reset. On ASPEED platforms, boot status is recorded in the SCU registers. - AST2400: Only a bit is used to represent system reset triggered by any WDT controller. - AST2500/AST2600: System reset triggered by different WDT controllers can be distinguished by different SCU bits. Besides, on AST2400 and AST2500, since alternating boot event is also triggered by using WDT timeout mechanism, it is classified as WDIOF_CARDRESET.

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks Pull kthread updates from Frederic Weisbecker: "Kthreads affinity follow either of 4 existing different patterns: 1) Per-CPU kthreads must stay affine to a single CPU and never execute relevant code on any other CPU. This is currently handled by smpboot code which takes care of CPU-hotplug operations. Affinity here is a correctness constraint. 2) Some kthreads _have_ to be affine to a specific set of CPUs and can't run anywhere else. The affinity is set through kthread_bind_mask() and the subsystem takes care by itself to handle CPU-hotplug operations. Affinity here is assumed to be a correctness constraint. 3) Per-node kthreads _prefer_ to be affine to a specific NUMA node. This is not a correctness constraint but merely a preference in terms of memory locality. kswapd and kcompactd both fall into this category. The affinity is set manually like for any other task and CPU-hotplug is supposed to be handled by the relevant subsystem so that the task is properly reaffined whenever a given CPU from the node comes up. Also care should be taken so that the node affinity doesn't cross isolated (nohz_full) cpumask boundaries. 4) Similar to the previous point except kthreads have a _preferred_ affinity different than a node. Both RCU boost kthreads and RCU exp kworkers fall into this category as they refer to "RCU nodes" from a distinctly distributed tree. Currently the preferred affinity patterns (3 and 4) have at least 4 identified users, with more or less success when it comes to handle CPU-hotplug operations and CPU isolation. Each of which do it in its own ad-hoc way. This is an infrastructure proposal to handle this with the following API changes: - kthread_create_on_node() automatically affines the created kthread to its target node unless it has been set as per-cpu or bound with kthread_bind[_mask]() before the first wake-up. - kthread_affine_preferred() is a new function that can be called right after kthread_create_on_node() to specify a preferred affinity different than the specified node. When the preferred affinity can't be applied because the possible targets are offline or isolated (nohz_full), the kthread is affine to the housekeeping CPUs (which means to all online CPUs most of the time or only the non-nohz_full CPUs when nohz_full= is set). kswapd, kcompactd, RCU boost kthreads and RCU exp kworkers have been converted, along with a few old drivers. Summary of the changes: - Consolidate a bunch of ad-hoc implementations of kthread_run_on_cpu() - Introduce task_cpu_fallback_mask() that defines the default last resort affinity of a task to become nohz_full aware - Add some correctness check to ensure kthread_bind() is always called before the first kthread wake up. - Default affine kthread to its preferred node. - Convert kswapd / kcompactd and remove their halfway working ad-hoc affinity implementation - Implement kthreads preferred affinity - Unify kthread worker and kthread API's style - Convert RCU kthreads to the new API and remove the ad-hoc affinity implementation" * tag 'kthread-for-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks: kthread: modify kernel-doc function name to match code rcu: Use kthread preferred affinity for RCU exp kworkers treewide: Introduce kthread_run_worker[_on_cpu]() kthread: Unify kthread_create_on_cpu() and kthread_create_worker_on_cpu() automatic format rcu: Use kthread preferred affinity for RCU boost kthread: Implement preferred affinity mm: Create/affine kswapd to its preferred node mm: Create/affine kcompactd to its preferred node kthread: Default affine kthread to its preferred NUMA node kthread: Make sure kthread hasn't started while binding it sched,arm64: Handle CPU isolation on last resort fallback rq selection arm64: Exclude nohz_full CPUs from 32bits el0 support lib: test_objpool: Use kthread_run_on_cpu() kallsyms: Use kthread_run_on_cpu() soc/qman: test: Use kthread_run_on_cpu() arm/bL_switcher: Use kthread_run_on_cpu()
2025-01-08treewide: Introduce kthread_run_worker[_on_cpu]()Frederic Weisbecker1-1/+1
kthread_create() creates a kthread without running it yet. kthread_run() creates a kthread and runs it. On the other hand, kthread_create_worker() creates a kthread worker and runs it. This difference in behaviours is confusing. Also there is no way to create a kthread worker and affine it using kthread_bind_mask() or kthread_affine_preferred() before starting it. Consolidate the behaviours and introduce kthread_run_worker[_on_cpu]() that behaves just like kthread_run(). kthread_create_worker[_on_cpu]() will now only create a kthread worker without starting it.

Unfortunately it's not unlikely that load_val contains LOAD_MAX, which is 0xFFFFFFFF and wraps to zero when one is added to it, resulting in the time left being understated by about 21.7s.
