The lid state may change while the machine is suspended. As such, we may need to re-check the state at wake-up time (at least when waking up from hibernation). Add the appropriate call to the resume handler in order to sync the SW_TABLET_MODE switch state with the hardware state.

2020-11-12platform/chrome: Don't treat RTC events as wakeup sourcesStephen Boyd1-5/+9
The EC sends an RTC host event when the RTC fires, but we don't need to treat that as a wakeup event here. The RTC class already properly handles activating and deactivating a wakeup source in rtc_update_irq() by calling pm_stay_awake() at the start of processing and pm_relax() once all expired RTC timers have been processed. This reduces one wakeup increment but not much else. I noticed this while debugging RTC wakeups and how they always incremented the wakeup count by two instead of one because this is duplicated.

2020-11-10platform/x86: panasonic-laptop: Add sysfs attributes for firmware brightness ↵Kenneth Chan1-0/+109
registers Panasonic laptops (at least from CF-W4 onwards) have dedicated firmware registers for saving ac/dc and current brightness. They are a bit confusing so here's some explanations: AC_MIN_BRIGHT, AC_MAX_BRIGHT, DC_MIN_BRIGHT, DC_MAX_BRIGHT: Read-only. Values: 0x01 and 0x15 respectively. AC_CUR_BRIGHT, DC_CUR_BRIGHT: Read-Write. 0x00-0xFF. Store user-defined AC/DC brightness. However, they do not represent current brightness so they should be named AC_BRIGHT and DC_BRIGHT instead. CUR_BRIGHT (present since CF-W4): Read-Write. 0x00-0xFF. It sets the current brightness. It won't update itself if brightness is changed via other means, e.g. acpi_video0. Another CUR_BRIGHT (added since CF-W5): Read-Write. 0x01-0x15. Its value always synchronizes with current brightness. Not implemented in this version. Currently the backlight API interacts with AC_CUR_BRIGHT (probably because it's the only bl register available in earlier models?). This patch adds sysfs attributes for AC_CUR_BRIGHT, DC_CUR_BRIGHT and CUR_BRIGHT. It also fixes the error of https://lkml.org/lkml/2020/8/19/1264. PS: I think the backlight API should interact with CUR_BRIGHT instead of AC_CUR_BRIGHT. But it involves complications like mapping between 0x01-0x15 or 0x00-0x14 (the backlight API) and 0x00-0xFF (CUR_BRIGHT). I'll leave the discussion for a later version.

2020-11-09platform/x86: thinkpad_acpi: Do not report SW_TABLET_MODE on Yoga 11eHans de Goede1-1/+8
The Yoga 11e series has 2 accelerometers described by a BOSC0200 ACPI node. This setup relies on a Windows service which reads both accelerometers and then calculates the angle between the 2 halves to determine laptop / tent / tablet mode and then reports the calculated mode back to the EC by calling special ACPI methods on the BOSC0200 node. The bmc150 iio driver does not support this (it involves double calculations requiring sqrt and arccos so this really needs to be done in userspace), as a result of this on the Yoga 11e the thinkpad_acpi code always reports SW_TABLET_MODE=0, starting with GNOME 3.38 reporting SW_TABLET_MODE=0 causes GNOME to: 1. Not show the onscreen keyboard when a text-input field is focussed with the touchscreen. 2. Disable accelerometer based auto display-rotation. This makes sense when in laptop-mode but not when in tablet-mode. But since for the Yoga 11e the thinkpad_acpi code always reports SW_TABLET_MODE=0, GNOME does not know when the device is in tablet-mode. Stop reporting the broken (always 0) SW_TABLET_MODE on Yoga 11e models to fix this. Note there are plans for userspace to support 360 degree hinges style 2-in-1s with 2 accelerometers and figure out the mode by itself, see: https://gitlab.freedesktop.org/hadess/iio-sensor-proxy/-/issues/216 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20201106140130.46820-1-hdegoede@redhat.com

2020-11-09platform/surface: Add Driver to set up lid GPEs on MS Surface deviceMaximilian Luz3-0/+320
Conventionally, wake-up events for a specific device, in our case the lid device, are managed via the ACPI _PRW field. While this does not seem strictly necessary based on ACPI spec, the kernel disables GPE wakeups to avoid non-wakeup interrupts preventing suspend by default and only enables GPEs associated via the _PRW field with a wake-up capable device. This behavior has been introduced in commit f941d3e41da7 ("ACPI: EC / PM: Disable non-wakeup GPEs for suspend-to-idle") and is described in more detail in its commit message. Unfortunately, on MS Surface devices, there is no _PRW field present on the lid device, thus no GPE is associated with it, and therefore the GPE responsible for sending the status-change notification to the lid gets disabled during suspend, making it impossible to wake the device via the lid. This patch introduces a pseudo-device and respective driver which, based on some DMI matching, marks the corresponding GPE of the lid device for wake and enables it during suspend.

2020-11-04platform/x86: Intel PMT Crashlog capability driverAlexander Duyck3-0/+340
Add support for the Intel Platform Monitoring Technology crashlog interface. This interface provides a few sysfs values to allow for controlling the crashlog telemetry interface as well as a character driver to allow for mapping the crashlog memory region so that it can be accessed after a crashlog has been recorded. This driver is meant to only support the server version of the crashlog which is identified as crash_type 1 with a version of zero. Currently no other types are supported.

2020-11-04platform/x86: Intel PMT Telemetry capability driverAlexander Duyck3-0/+172
PMT Telemetry is a capability of the Intel Platform Monitoring Technology. The Telemetry capability provides access to device telemetry metrics that provide hardware performance data to users from read-only register spaces. With this driver present the intel_pmt directory can be populated with telem<x> devices. These devices will contain the standard intel_pmt sysfs data and a "telem" binary sysfs attribute which can be used to access the telemetry data. Also create a PCI device id list for early telemetry hardware that require workarounds for known issues. Signed-off-by: Alexander Duyck <alexander.h.duyck@linux.intel.com> Co-developed-by: David E.

2020-11-04platform/x86: Intel PMT class driverAlexander Duyck4-0/+362
Intel Platform Monitoring Technology is meant to provide a common way to access telemetry and system metrics. Register mappings are not provided by the driver. Instead, a GUID is read from a header for each endpoint. The GUID identifies the device and is to be used with an XML, provided by the vendor, to discover the available set of metrics and their register mapping. This allows firmware updates to modify the register space without needing to update the driver every time with new mappings. Firmware writes a new GUID in this case to specify the new mapping. Software tools with access to the associated XML file can then interpret the changes. The module manages access to all Intel PMT endpoints on a system, independent of the device exporting them. It creates an intel_pmt class to manage the devices. For each telemetry endpoint, sysfs files provide GUID and size information as well as a pointer to the parent device the telemetry came from. Software may discover the association between endpoints and devices by iterating through the list in sysfs, or by looking for the existence of the class folder under the device of interest. A binary sysfs attribute of the same name allows software to then read or map the telemetry space for direct access.

2020-10-28platform/x86: acer-wmi: Add support for SW_TABLET_MODE on Switch devicesHans de Goede1-3/+106
Add support for SW_TABLET_MODE on the Acer Switch 10 (SW5-012) and the acer Switch 10 (S1003) models. There is no way to detect if this is supported, so this uses DMI based quirks setting force_caps to ACER_CAP_KBD_DOCK (these devices have no other acer-wmi based functionality). The new SW_TABLET_MODE functionality can be tested on devices which are not in the DMI table by passing acer_wmi.force_caps=0x40 on the kernel commandline.

Add a new force_caps module parameter to allow overriding the drivers builtin capability detection mechanism. This can be used to for example: -Disable rfkill functionality on devices where there is an AA OEM DMI record advertising non functional rfkill switches -Force loading of the driver on devices with a missing AA OEM DMI record Note that force_caps is -1 when unset, this allows forcing the capability field to 0, which results in acer-wmi only providing WMI hotkey handling while disabling all other (led, rfkill, backlight) functionality.

2020-10-28platform/x86: asus-wmi: Add support for SW_TABLET_MODE on UX360Samuel Čavoj3-0/+56
The UX360CA has a WMI device id 0x00060062, which reports whether the lid is flipped in tablet mode (1) or in normal laptop mode (0). Add a quirk (quirk_asus_use_lid_flip_devid) for devices on which this WMI device should be used to figure out the SW_TABLET_MODE state, as opposed to the quirk_asus_use_kbd_dock_devid. Additionally, the device needs to be queried on resume and restore because the firmware does not generate an event if the laptop is put to sleep while in tablet mode, flipped to normal mode, and later awoken. It is assumed other UX360* models have the same WMI device. As such, the quirk is applied to devices with DMI_MATCH(DMI_PRODUCT_NAME, "UX360"). More devices with this feature need to be tested and added accordingly. The reason for using an allowlist via the quirk mechanism is that the new WMI device (0x00060062) is also present on some models which do not have a 360 degree hinge (at least FX503VD and GL503VD from Hans' DSTS collection) and therefore its presence cannot be relied on.
