* Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)Pawel Biernacki2020-02-261-4/+5
| | | | | | | | | | | | | | | | | | | r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are still not MPSAFE (or already are but aren’t properly marked). Use it in preparation for a general review of all nodes. This is non-functional change that adds annotations to SYSCTL_NODE and SYSCTL_PROC nodes using one of the soon-to-be-required flags. Mark all obvious cases as MPSAFE. All entries that haven't been marked as MPSAFE before are by default marked as NEEDGIANT Approved by: kib (mentor, blanket) Commented by: kib, gallatin, melifaro Differential Revision: https://reviews.freebsd.org/D23718 Notes: svn path=/head/; revision=358333
* wbwd: small clean-ups and improvementsAndriy Gapon2019-10-171-10/+21
| | | | | | | | | | | | This change applies some suggestions by delphij from D21979. A write-only variable is removed. There is a diagnostic message if the driver does not recognize the chip. A chained if-statement is converted to a switch. MFC after: 3 weeks Notes: svn path=/head/; revision=353677
* wbwd: move to superio(4) busAndriy Gapon2019-10-161-333/+70
| | | | | | | | | | | | | | | | | | | | | This allows to remove a bunch of low level code. Also, superio(4) provides safer interaction with other drivers that work with Super I/O configuration registers. Tested only on PCengines APU2: superio0: <Nuvoton NCT5104D/NCT6102D/NCT6106D (rev. B+)> at port 0x2e-0x2f on isa0 wbwd0: <Nuvoton NCT6102 (0xc4/0x53) Watchdog Timer> at WDT ldn 0x08 on superio0 The watchdog output is incorrectly wired on that system and the watchdog does not really do it its job, but the pulse can be seen with a signal analyzer.

* sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | 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

* Remove watchdog timer stop check.Alexander Motin2016-04-141-13/+4
| | | | | | | | | | | There are bunch of reports that this check fails at least on Nuvoton NCT6776 chips. I don't see why this check needed there, and Linux does not have it either. So far this check only made watchdogd unstopable. MFC after: 1 month Notes: svn path=/head/; revision=297963

* sbuf_trim() cannot be used on sbuf with drain function set.Pawel Jakub Dawidek2012-12-151-2/+1
| | | | | | | | | | | | | | | | | | This fixes panic when listing sysctls on INVARIANTS-enabled kernel while having wbwd loaded. This panic was not fatal, at worst one additional space was printed. Also sbuf_trim() makes some sense even if drain function is set. The drain function is called only when buffer is to be expanded. So we could still trim existing buffer before drain is called. In this case it worked just fine - the trailing space was correctly trimmed. Obtained from: WHEEL Systems MFC after: 1 week Notes: svn path=/head/; revision=244280

Winbond Super I/O chips. With minor efforts it should be possible the extend the driver to support further chips/revisions available from Winbond. In the simplest case only new IDs need to be added, while different chipsets might require their own function to enter extended function mode, etc. Sponsored by: Sandvine Incorporated ULC (in 2011) Reviewed by: emaste, brueffer MFC after: 2 weeks Notes: svn path=/head/; revision=232614
