* ichwd: Add Atom C3000 watchdog ID.Justin Hibbits2020-03-242-0/+2

* Extract eventfilter declarations to sys/_eventfilter.hConrad Meyer2019-05-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h" in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header pollution substantially. EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c files into appropriate headers (e.g., sys/proc.h, powernv/opal.h). As a side effect of reduced header pollution, many .c files and headers no longer contain needed definitions. The remainder of the patch addresses adding appropriate includes to fix those files. LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by sys/mutex.h since r326106 (but silently protected by header pollution prior to this change). No functional change (intended). Of course, any out of tree modules that relied on header pollution for sys/eventhandler.h, sys/lock.h, or sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.

* ichwd: add a few assertions about tco_versionAndriy Gapon2018-12-181-0/+7
| | | | | | | | | | | | | | Those should ensure correctness of ichwd_find_ich_lpc_bridge() and ichwd_find_ich_lpc_bridge() as well as make it easier for both humans and static analyzers to see the relation between tco_version and ich and smb variables in ichwd_identify().

* ichwd: add support for TCO watchdog timer in Lewisburg PCH (C620)Andriy Gapon2018-10-222-16/+153
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The change is based on public documents listed below as well as Linux changes and the code developed by Kostik. The documents: - Intel® C620 Series Chipset Platform Controller Hub Datasheet - Intel® 100 Series and Intel® C230 Series Chipset Family Platform Controller Hub (PCH) Datasheet - Volume 2 of 2 Interesting Linux commits: - https://github.com/torvalds/linux/commit/9424693035a57961a8eb09e96aab315a7096535d - https://github.com/torvalds/linux/commit/2a7a0e9bf7b32e838d873226808ab8a6c00148f7 The peculiarity of the new chipsets is that the watchdog resources are configured in PCI registers of SMBus controller and Power Management function as opposed to the LPC bridge. I took a simplistic approach of querying the resources from the respective PCI devices. ichwd is still a device on isa bus. The PCI devices are found by their slot and function defined in the datasheets as siblings of the upstream LPC bridge. There are some shortcuts and missing features. First of all, I have not implemented the functionality required to clear the no-reboot bit. That would require writing to a special PCI configuration register of a hidden / invisible PCI device after which the device would start responding to accesses to other registers. The no-reboot bit was not set on my test hardware, so I decided to leave its handling for the later time. Also, I did not try to handle the case where the watchdog resources are not configured by the hardware as well as the case where ACPI defined operational region conflicts with the watchdog resources. My test system did not have either of those problem, so, again, I decided to leave those cases until later. See this Linux commit for some details of the ACPI problem: https://github.com/torvalds/linux/commit/a7ae81952cdab56a1277bd2f9ed7284c0f575120 Finally, I have added only the PCI ID found on my test system. I think that more IDs can be added as the change gets tested. Tested on Dell PowerEdge R740.

* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-272-0/+4
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255
