* Release the acpi lock around calls to wsdisplay_suspend() andkettenis2014-09-231-1/+9
| | | | | | | | | | | | | | wsdisplay_resume(). The X server may adjust the display brightness just before/after the VT switch when suspending/resuming. In fact, it may already be blocked adjusting the display brightness for some reason unrelated to the suspend request. The VT switch request will eventually time out, but the delay is annoying and the failed VT switch will lead to problems after resume. Needed for a future update of the xf86-video-intel driver. ok mlarkin@

* SystemMemory is used to access memory mapped registers on some machines, so wekettenis2014-06-231-27/+22

* Fix invalid / missing format specifiers in several dnprintf statementsmlarkin2014-05-211-4/+4
| | | | | | | (used only when ACPI_DEBUG is enabled) From a diff on tech@ by Fabian Raetz, with a minor change by me, tested on i386 and amd64 with ACPI_DEBUG enabled and disabled.
* Defer the free of the hibernate structures until later, when it is safe tomlarkin2014-04-251-1/+9
| | | | | | | | | | do so. Freeing the hibernate structures too early leads to inadvertent calls into splx when we aren't ready for them yet. Found when trapping splx calls in the resume path. discussed with deraadt@ at m2k14

* Change the order of operations during a suspend/resume cycle andmpi2014-03-311-3/+4
| | | | | | | | | | | | | | call bufq_quiesce() after executing the DVACT_QUIESCE handlers. This should be safe since no disk nor controller drivers have such handler but it will allow us to detach sd(4) devices attached to a USB bus. Another benefit pointed out by kettenis@ is that drivers that need to read a firmware from the disk should be able to do it at resume time in a DVACT_WAKEUP handler. ok kettenis@, deraadt@
* get rid of the assumption that the head of the alldevs list is thedlg2014-03-131-5/+6
| | | | | | | | | | | "mainbus" device. this breaks when mpath is enabled because it attaches before mainbus and therefore takes the head position. have autoconf provide device_mainbus() which looks up mainbus_cd, and use that instead. discussed with deraadt who just wants mpath stuff to move forward despite there being many ways to shine this particular turd.

| | | | | | | | fadt->hdr_revision <= 1. This is a better check since it checks the version of the proper descriptor. This allows the alix APU to reboot since those boards have currently a wrong sc->sc_revision. Committing this now so that it can be tested easier. With and OK jsg@ also fine by derradt@

| | | | | | | | kernel resumes normal (non-cold, able to run processes, etc) operation. Previously we were relying on specific DVACT_RESUME op's in drivers creating callback/threads themselves, but that has become too common, indicating the need for a built-in mechanism. ok dlg kettenis, tested by a sufficient amount of people
* Add support for Power Resources for Dx states and the necessary hookmpi2013-11-061-8/+84
| | | | | | | | | | | | | | | | for PCI devices. This hook should be called twice, before and after changing the power state of a PCI device. Before setting the device to the new state, the ACPI layer will notify every power resources linked to the device for that state and make sure they are turned "_ON". After changing the state of the device, it will decrement the reference of every power resources linked to that device for the old state and turn them "_OFF" if they are no longer referenced. This fixes the no-USB after resume problem seen on various ThinkPad, problem initialy diagnosed with Alexander Polakov. ok kettenis@, deraadt@

* Revamp the sequences for suspend/hibernate -> resume so that the codederaadt2012-10-081-255/+176
| | | | | | | | | | paths are reflexive. It is now possible to fail part-way through a suspend sequence, and recover along the resume code path. Split DVACT_SUSPEND by adding a new DVACT_POWERDOWN method is used after hibernate (and suspend too) to finish the job. Some drivers must be converted at the same time to use this instead of shutdown hooks (the others will follow at a later time) ok kettenis mlarkin
