acpi_ibm: add support for ThinkPad PrivacyGuard ThinkPad PrivacyGuard is a built-in toggleable privacy filter that restricts viewing angles when on. It is an available on some new ThinkPad models such as the X1 Carbon 7th gen (as an optional HW upgrade). The privacy filter can be enabled/disabled via an ACPI call. This commit adds a sysctl under dev.acpi_ibm that allows for getting and setting the PrivacyGuard state.

Fix build of aibs with base gcc on i386

2018-06-17T19:14:05Z

Add a few intermediate casts to intptr_t to suppress "cast to pointer from integer of different size" warnings from gcc. In this case, the 'arg2' part of SYSCTL_HANDLER_ARGS is used to pass in a pointer, via an intermediate intmax_t, so no information is lost.

Set of improvements to acpi_hp(4) driver.

2016-11-12T05:09:39Z

- Attach only to WMI devices that provide supported GUIDs. HP Spectre x360 has two WMI devices, only one of which provides the GUIDs. - Pass proper device to ACPI_WMI_REMOVE_EVENT_HANDLER() on detach. - Improve error WMI handling separating status and data paths. This allows to hide sysctls not supported by specific hardware/BIOS. - Improve CMI block parser to make it work on HP Spectre x360 laptop. - In verbose mode log all unknown events to help futher improvements.

Comparing to the Linux driver there is still one missing feature. The Linux driver finds and enables "Embedded Controller" item in the 0x11 group if it's not enabled yet. I tested the new method, Torfinn Ingolfsen tested the old method and helped to fix several bugs in the earlier versions of the patch.

After r285994, sysctl(8) was fixed to use 273.15 instead of 273.20 as 0C reference and as result, the temperature read in sysctl(8) now exibits a +0.1C difference. This commit fix the kernel references to match the reference value used in sysctl(8) after r285994. Sponsored by: Rubicon Communications (Netgate)
