2020-11-26T14:48:55Z

The Pavilion 13 x360 PC has a chassis-type which does not indicate it is a convertible, while it is actually a convertible. Add it to the dmi_switches_allow_list. Signed-off-by: Max Verevkin Link: https://lore.kernel.org/r/20201124131652.11165-1-me@maxverevkin.tk Signed-off-by: Hans de Goede

platform/x86: toshiba_acpi: Fix the wrong variable assignment

2020-11-26T14:48:46Z

The commit 78429e55e4057 ("platform/x86: toshiba_acpi: Clean up variable declaration") cleans up variable declaration in video_proc_write(). Seems it does the variable assignment in the wrong place, this results in dead code and changes the source code logic. Fix it by doing the assignment at the beginning of the funciton.

platform/x86: thinkpad_acpi: Send tablet mode switch at wakeup time

2020-11-26T14:45:24Z

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.

platform/x86: thinkpad_acpi: Add BAT1 is primary battery quirk for Thinkpad Yoga 11e 4th gen

2020-11-26T14:44:44Z

The Thinkpad Yoga 11e 4th gen with the N3450 / Celeron CPU only has one battery which is named BAT1 instead of the expected BAT0, add a quirk for this. This fixes not being able to set the charging tresholds on this model; and this alsoe fixes the following errors in dmesg: ACPI: \_SB_.PCI0.LPCB.EC__.HKEY: BCTG evaluated but flagged as error thinkpad_acpi: Error probing battery 2 battery: extension failed to load: ThinkPad Battery Extension battery: extension unregistered: ThinkPad Battery Extension Note that the added quirk is for the "R0K" BIOS versions which are used on the Thinkpad Yoga 11e 4th gen's with a Celeron CPU, there is a separate "R0L" BIOS for the i3/i5 based versions. This may also need the same quirk, but if that really is necessary is unknown. Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20201109103550.16265-1-hdegoede@redhat.com

platform/x86: thinkpad_acpi: Do not report SW_TABLET_MODE on Yoga 11e

2020-11-26T14:44:35Z

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 Link: https://lore.kernel.org/r/20201106140130.46820-1-hdegoede@redhat.com

platform/x86: thinkpad_acpi: add P1 gen3 second fan support

2020-11-26T14:44:09Z

Tested on my P1 gen3, works fine with `thinkfan`.
