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@

| | | | | | | | | | | 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@

* The ACPI standard says that a PCI function number of FFFF can be used to referkettenis2015-03-201-1/+16
| | | | | | | | | | | | | to all functions on a device. This makes no sense in the context of accessing PCI config space. Nevertheless stsp@ has a machine with AML that tries to do config space reads from a device where _ADR encodes function number FFFF. This is almost certainly buggy AML, but since Linux (and presumably Windows) boot just fine on this machine we need to work around this. Linux effectively treats function FFFF as function 7, which isn't present on this machine. Instead we simulate a read from a non-existent device by returning a bit pattern of all ones. Writes to function FFFF will still panic. ok mlarkin@

* Rework piglet and pig allocation. Currently the piglet gets allocatedkettenis2014-09-261-11/+14
| | | | | | | | | | | | | | deep down in the suspend path, where it is really hard to recover from allocation failure. So allocate the piglet early on in the suspend path. Also change the piglet and piglet allocation functions to use km_alloc(9) instead of doing pmemrange magic. This removes a bunch of code which, in the case of the piglet allocation, is broken since it results in a NULL pointer dereference. Also switch the piglet allocation to not wait. If we can't allocate 16MB of phys contig memory on a halfway modern machine we're almost certainly under a lot of memory pressure and we're better off not trying to hibernate anyway. ok mlarkin@
