* Remove almost unused `flags' argument of suser().mpi2018-02-191-2/+2
| | | | | | | 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@
* Syncronize filesystems to disk when suspending. Each mountpoint's vnodesderaadt2018-02-101-1/+7
| | | | | | | | | | 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.

* acpibat: look for _BIX first before falling back on _BIFjcs2017-07-221-3/+3
| | | | | | | | | | 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

| | | | | | | | | | | | | | | 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

* Make aml_rdpciaddr() work for for devices behind bridges. The code nowkettenis2017-01-081-13/+9
| | | | | | | | | | uses the mapping between AML nodes and PCI devices that we establish. Because _INIT methods may end up calling aml_rdpciaddr(), make sure we create that mapping early. Also handle devices that aren't actually present. These devices are now included in the mapping and reads will return an all-ones patterm whereas writes are a no-op.. ok mlarkin@

| | | | | | | | | | | | when acpicpu tries to attach, leading to a NULL dereference. The ACPI processor object on the Dells where this was reported is bogus and useless anyway so apply the same test when deciding whether to attach to processor objects as acpicpu would when matching them to cpus. Problem reported by Eivind Eide (xenofil (at) gmail.com) and Johan Huldtgren (johan+openbsd-bugs (at) huldtgren.com). Testing by Eivind Eide. ok kettenis@ mlarkin@

* Make sure devices listed by a device's _DEP method are attached beforekettenis2016-05-081-2/+34
| | | | | | | | | | | we attach the device itself. The _DEP methode, introduced in ACPI 5.0, is a hint that the device in question depends on OpRegion support from the devices listed by _DEP, so we have to order them the proper way. To prevent us from attaching those devices again when we encounter them later walking down the device tree, keep track of our attempts to attach a device driver to them using aflag in the aml_node structure. ok guenther@

* Adding each and every new acpi device driver to acpi_foundhid() iskettenis2016-03-281-25/+5
| | | | | | | | | | | | | | gettinga bit of the burden. And it really isn't how our autoconf framework is supposed to work for busses that can be enumerated. All the drivers already check for a matching _HID in their attach function. So we can just drop the checks in acpi_foundhid() and let the drivers sort themselves out. Print a "not configured" line for devices for which we don't attach adriver. This may be a bit much as there are devices for which we will not have a driver. This will be removed if it causes too much dmesg spam. ok deraadt@, mlarkin@

Add ihidev, a HID-over-i2c driver largely based on uhidev. dwiic handles attaching ihidev devices found in ACPI. Add ims, a HID-over-i2c mouse/trackpad driver to get basic cursor and button functionality from HID-compliant i2c trackpads. ok kettenis deraadt
