i6300esbwd: Set error appropriately on event

2026-03-13T18:49:17Z

Per the watchdog driver contract, if the driver successfully arms the watchdog it must set error to 0, and if it's unable to arm the watchdog it must leave error alone. Sponsored by: Hewlett Packard Enterprise

ichwd: introduce i6300esbwd watch dog driver

2025-08-25T15:45:24Z

The intel 6300ESB watchdog is a special ICH-based watchdog device with a different interface. QEMU implements this watchdog for x86 systems. This change enables watchdog mode (rather than free-running mode) and introduces 1 sysctl: - hw.i6300esbwd.0.locked: locks the watchdog register after the event is triggered, preventing it from being disabled until a hard reset. This feature has been tested on a Vultr AMD guest machine and local qemu machine.

pci_cfgreg: Add a PCI domain argument to the low-level register API

2023-11-29T18:31:47Z

This commit changes the API of pci_cfgreg(read|write) to add a domain argument (referred to as a segment in ACPI parlance) (note that this is not the same as a NUMA domain, but something PCI-specific). This does not yet enable access to domains other than 0, but updates the API to support domains. Places that use hard-coded bus/slot/function addresses have been updated to hardcode a domain of 0. A few places that have the PCI domain (segment) available such as the acpi_pcib_acpi.c Host-PCI bridge driver pass the PCI domain. The hpt27xx(4) and hptnr(4) drivers fail to attach to a device not on domain 0 since they provide APIs to their binary blobs that only permit bus/slot/function addressing. The x86 non-ACPI PCI bus drivers all hardcode a domain of 0 as they do not support multiple domains. Reviewed by: imp Differential Revision: https://reviews.freebsd.org/D42827
