| * 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds watchdog support for the ITE IT8659 watchdog. IT8659 watchdog works in the same way as the other watchdogs supported by it87_wdt. Before this patch, IT8659 watchdog is not supported. After a modprobe, dmesg reports: it87_wdt: Unknown Chip found, Chip 8659 Revision 0007 With this patch, modprobe it87_wdt recognizes the watchdog as the dmesg output shows: it87_wdt: Chip IT8659 revision 7 initialized. timeout=60 sec (nowayout=0 testmode=0) Watchdog tests on a YANLING YL-ALP3L2C-1235U system have been successful, the watchdog works as expected with this patch.

| * watchdog: bcm2835_wdt: Fix WDIOC_SETTIMEOUT handlingStefan Wahren2023-12-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Users report about the unexpected behavior for setting timeouts above 15 sec on Raspberry Pi. According to watchdog-api.rst the ioctl WDIOC_SETTIMEOUT shouldn't fail because of hardware limitations. But looking at the code shows that max_timeout based on the register value PM_WDOG_TIME_SET, which is the maximum. Since 664a39236e71 ("watchdog: Introduce hardware maximum heartbeat in watchdog core") the watchdog core is able to handle this problem. This fix has been tested with watchdog-test from selftests.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Avoid unnecessary crashes by claiming only NMIs that are due to ERROR signalling or generated by the hpwdt hardware device. The code does this, but only for iLO5. The intent was to preserve legacy, Gen9 and earlier, semantics of using hpwdt for error containtment as hardware/firmware would signal fatal IO errors as an NMI with the expectation of hpwdt crashing the system. Howerver, these IO errors should be received by hpwdt as an NMI_IO_CHECK. So the test is overly permissive and should not be limited to only ilo5. We need to enable this protection for future iLOs not matching the current PCI IDs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On today's platforms the benefit of platform_driver_probe() isn't that relevant any more. It allows to drop some code after booting (or module loading) for .probe() and discard the .remove() function completely if the driver is built-in. This typically saves a few 100k. The downside of platform_driver_probe() is that the driver cannot be bound and unbound at runtime which is ancient and also slightly complicates testing. There are also thoughts to deprecate platform_driver_probe() because it adds some complexity in the driver core for little gain. Also many drivers don't use it correctly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the new watchdog character device is registered, it becomes available for opening. This creates a race where userspace may open the device before the character device's owner is set. This results in an imbalance in module_get calls as the cdev_get in cdev_open will not increment the reference count on the watchdog driver module. This causes problems when the watchdog character device is released as the module loader's reference will also be released. This makes it impossible to open the watchdog device later on as it now appears that the module is being unloaded. The open will fail with -ENXIO from chrdev_open. The legacy watchdog device will fail with -EBUSY from the try_module_get in watchdog_open because it's module owner is the watchdog core module so it can still be opened but it will fail to get a refcount on the underlying watchdog device driver.

The gwdt->clk and timeout are u32, but the argument being calculated is u64. Without a cast, the compiler performs u32 operations, truncating intermediate steps, resulting in incorrect values. A watchdog revision 1 implementation with a gwdt->clk of 1GHz and a timeout of 600s writes 3647256576 to the one shot watchdog instead of 300000000000, resulting in the watchdog firing in 3.6s instead of 600s. Force u64 math by casting the first argument (gwdt->clk) as a u64. Make the order of operations explicit with parenthesis.

* / arch: Remove Itanium (IA-64) architectureArd Biesheuvel2023-09-111-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Itanium architecture is obsolete, and an informal survey [0] reveals that any residual use of Itanium hardware in production is mostly HP-UX or OpenVMS based. The use of Linux on Itanium appears to be limited to enthusiasts that occasionally boot a fresh Linux kernel to see whether things are still working as intended, and perhaps to churn out some distro packages that are rarely used in practice. None of the original companies behind Itanium still produce or support any hardware or software for the architecture, and it is listed as 'Orphaned' in the MAINTAINERS file, as apparently, none of the engineers that contributed on behalf of those companies (nor anyone else, for that matter) have been willing to support or maintain the architecture upstream or even be responsible for applying the odd fix. The Intel firmware team removed all IA-64 support from the Tianocore/EDK2 reference implementation of EFI in 2018. (Itanium is the original architecture for which EFI was developed, and the way Linux supports it deviates significantly from other architectures.) Some distros, such as Debian and Gentoo, still maintain [unofficial] ia64 ports, but many have dropped support years ago. While the argument is being made [1] that there is a 'for the common good' angle to being able to build and run existing projects such as the Grid Community Toolkit [2] on Itanium for interoperability testing, the fact remains that none of those projects are known to be deployed on Linux/ia64, and very few people actually have access to such a system in the first place. Even if there were ways imaginable in which Linux/ia64 could be put to good use today, what matters is whether anyone is actually doing that, and this does not appear to be the case. There are no emulators widely available, and so boot testing Itanium is generally infeasible for ordinary contributors. GCC still supports IA-64 but its compile farm [3] no longer has any IA-64 machines. GLIBC would like to get rid of IA-64 [4] too because it would permit some overdue code cleanups. In summary, the benefits to the ecosystem of having IA-64 be part of it are mostly theoretical, whereas the maintenance overhead of keeping it supported is real. So let's rip off the band aid, and remove the IA-64 arch code entirely. This follows the timeline proposed by the Debian/ia64 maintainer [5], which removes support in a controlled manner, leaving IA-64 in a known good state in the most recent LTS release. Other projects will follow once the kernel support is removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After issuing a "poweroff" command the board goes through the expected power-off sequence and turns it off completely: systemd-shutdown[1]: Powering off. imx2-wdt 30280000.watchdog: Device shutdown: Expect reboot! reboot: Power down The "Expect reboot!" message is misleading because in the power-off case, no reboot is expected to happen at all. Avoid the confusion by removing the "Expect reboot!" message.
