2018-03-27Add acpicmos(4), a driver that implements SystemCMOS OperationRegionMark Kettenis
access support. This fixes machines where the AML doesn't check whether support for this OperationRegion type has been registered by the OS. ok mlarkin@
2018-03-14On newer machines IPMI attaches only using the ACPI tables instead ofPatrick Wildt
the SMBIOS table. Some machines even have IPMI defined in both tables. This attachment driver makes ipmi(4) available via ACPI. There can only attach one ipmi(4) device, either on ACPI or SMBIOS. Akin to the SMBIOS-attached ipmi(4) this driver is disabled by default. Feedback from jsg@ ok deraadt@
2018-02-19Remove almost unused `flags' argument of suser().Martin Pieuchot
The account flag `ASU' will no longer be set but that makes suser() mpsafe since it no longer mess with a per-process field. No objection from millert@, ok tedu@, bluhm@
2018-02-10Syncronize filesystems to disk when suspending. Each mountpoint's vnodesTheo de Raadt
are pushed to disk. Dangling vnodes (unlinked files still in use) and vnodes undergoing change by long-running syscalls are identified -- and such filesystems are marked dirty on-disk while we are suspended (in case power is lost, a fsck will be required). Filesystems without dangling or busy vnodes are marked clean, resulting in faster boots following "battery died" circumstances. Tested by numerous developers, thanks for the feedback.
2018-02-08After flushing disks, try again to release all memory. We don't need toTheo de Raadt
save dirty memory to the hibernate space.

of allocating the hibernate playpen.

output to the disks. This is part of a larger suspend/resume filesystem-safety diff, which has been worked on for a couple of months already. Tests by job, krw, beck, benno, and others. Sometimes even by snapshot users...

a time-of-day clock device based on the GetTime() and SetTime() services. The virtual memory mappings for the runtime services calls are implemented through a separate pmap that is only activated when we make a runtime services call. ok tom@, visa@ tested by naddy@

2017-10-06Recalibrate TSC timecounter with HPET and PM timerMike Belopuhov
If frequency of an invariant (non-stop) time stamp counter is measured using an independent working timecounter that has a known frequency, we can assume that the measured TSC frequency is as good as the resolution of the timecounter that we use to perform the measurement. This lets us switch from this high quality but expensive source to the cheaper TSC without sacrificing precision on a wide range of modern CPUs.

2017-07-22acpibat: look for _BIX first before falling back on _BIFJoshua Stein
ACPI 4.0 deprecated _BIF for battery status so some newer machines are exporting _BIX which extends _BIF's package with a few extra fields. When using _BIX, export the new discharge cycle count as a sensor. feedback from kettenis and anton ok deraadt

could be running inside a driver that will be force-detached, or due to tsleep end up disrupting the softstate/hardstate contract. At suspend time, quisce all these callbacks by waiting for completion. This issue has never been observed for real, but may be implicated in suspend/resume failures. ok kettenis guenther mlarkin

2017-03-11Revert 1.54, go back to always trying to enable burst modeJoshua Stein
Selectively enabling burst mode seems to have broken more machines than it helped. On MacBooks, EC_STAT_OBF occasionally won't show up when trying to read a byte of data when bursting hasn't been enabled, so acpiec_wait can spin forever. This again breaks on ECs that don't do burst at all, like the Chrome EC, but those are much more scarce than MacBooks at this time. A machine/bios-dependent check could be added later to disable bursting on certain machines. Discussed with deraadt
2017-03-07move a TODO to the topJoshua Stein
2017-03-02Add a new sysctl machdep.lidaction. The sysctl works as follows:Martin Natano
machdep.lidaction=0 # do nothing machdep.lidaction=1 # suspend machdep.lidaction=2 # hibernate lidsuspend is just an alias for lidaction, so if you change one, the other one will have the same value. The plan is to remove machdep.lidsuspend eventually when people have upgraded their /ets/sysctl.conf. discussed with deraadt, who came up with the new MIB name no objections mlarkin ok stsp halex jcs
