* disable acpivout brightness control on machines aware of Windows 8jsg2020-09-161-1/+59
| | | | | | | | | | | | | | | | | | On a HP ProBook 650 G1 acpivout backlight brightness control only works if we don't claim to be Windows 8. If we don't claim to be Windows 8 _BCL gives 21 levels with increments of 5, otherwise 101 levels (0-100) and a _BCM that does nothing. This is related to requirements Microsoft has for Windows 8 and later hardware certification. Having acpivout not fully attach lets inteldrm handle brightness ioctls. Brightness control via physical buttons will require a new acpi driver for the HP flavour of WMI. Add Windows 10 2004 _OSI value to the list while here. ok mpi@ kmos@ on an earlier version tested by kmos@ on 6460b and 6470b ProBooks which had the same problem feedback and ok kettenis@
* Add support for multiple PCI segments. Only really implemented for arm64kettenis2018-08-191-3/+4

* Add the resource index to aml_parse_resource() callback function.pirofti2016-10-251-2/+3

* Remove unused argument in aml_showvalue().pirofti2016-09-021-2/+2
| | | | | | | The second argument of aml_showvalue() was probably supposed to set the verbosity level through dnprintf() but in fact it does nothing. OK deraadt@

* Correct the value of SRT_ENDTAG: it was documented incorrectly in earlyguenther2016-03-141-2/+2
| | | | | | | ACPI specs. With the correct value, it can now be used in a few places instead of hardcoding 0x79. ok kettenis@
* Change aml_find_node() such that it only walks down the tree and doesn'tkettenis2016-01-131-2/+2
| | | | | | | | | | | | | | traverse sideways. This seems to be what all callersexpect it to do, and fixes a bug in dwiic(4) where it would try to access i2c devices on busses they're not attached to. If there is any fallout from this change, the right thing to do is probably to make sure callers pass the right node. While there, change the return type to void, as the return value was useless and none of the callers looked at it. ok mlarkin@

* Reduce use of SMALL_KERNEL in acpi, bringing acpiec driver and more gpederaadt2015-03-161-2/+2

* acpi: Add global lock enter and leave routines.pirofti2013-01-181-1/+4
| | | | | | | | I think this diff is the way to go if we want to have proper locking in our acpi drivers. This doesn't hook onto anything from the kernel and is just building framework towards locking. Okay mlarkin@, kettenis@.
