2020-01-29platform/x86: alienware-wmi: printing the wrong error codeDan Carpenter
[ Upstream commit 6d1f8b3d75419a8659ac916a1e9543bb3513a882 ] The "out_data" variable is uninitialized at the point. Originally, this used to print "status" instead and that seems like the correct thing to print.

2020-01-04platform/x86: hp-wmi: Make buffer for HPWMI_FEATURE2_QUERY 128 bytesHans de Goede
commit 133b2acee3871ae6bf123b8fe34be14464aa3d2c upstream. At least on the HP Envy x360 15-cp0xxx model the WMI interface for HPWMI_FEATURE2_QUERY requires an outsize of at least 128 bytes, otherwise it fails with an error code 5 (HPWMI_RET_INVALID_PARAMETERS): Dec 06 00:59:38 kernel: hp_wmi: query 0xd returned error 0x5 We do not care about the contents of the buffer, we just want to know if the HPWMI_FEATURE2_QUERY command is supported.

2019-12-05platform/x86: hp-wmi: Fix ACPI errors caused by too small bufferHans de Goede
commit 16245db1489cd9aa579506f64afeeeb13d825a93 upstream. The HP WMI calls may take up to 128 bytes of data as input, and the AML methods implementing the WMI calls, declare a couple of fields for accessing input in different sizes, specifycally the HWMC method contains: CreateField (Arg1, 0x80, 0x0400, D128) Even though we do not use any of the WMI command-types which need a buffer of this size, the APCI interpreter still tries to create it as it is declared in generoc code at the top of the HWMC method which runs before the code looks at which command-type is requested. This results in many of these errors on many different HP laptop models: [ 14.459261] ACPI Error: Field [D128] at 1152 exceeds Buffer [NULL] size 160 (bits) (20170303/dsopcode-236) [ 14.459268] ACPI Error: Method parse/execution failed [\HWMC] (Node ffff8edcc61507f8), AE_AML_BUFFER_LIMIT (20170303/psparse-543) [ 14.459279] ACPI Error: Method parse/execution failed [\_SB.WMID.WMAA] (Node ffff8edcc61523c0), AE_AML_BUFFER_LIMIT (20170303/psparse-543) This commit increases the size of the data element of the bios_args struct to 128 bytes fixing these errors.

[ Upstream commit b3f2f3799a972d3863d0fdc2ab6287aef6ca631f ] When the OS registers to handle events from the display off hotkey the EC will send a notification with 0x35 for every key press, independent of the backlight state. The behavior of this key on Windows, with the ATKACPI driver from Asus installed, is turning off the backlight of all connected displays with a fading effect, and any cursor input or key press turning the backlight back on. The key press or cursor input that wakes up the display is also passed through to the application under the cursor or under focus. The key that matches this behavior the closest is KEY_SCREENLOCK.

2019-01-26platform/x86: asus-wmi: Tell the EC the OS will handle the display off hotkeyJoão Paulo Rechi Vita
[ Upstream commit 78f3ac76d9e5219589718b9e4733bee21627b3f5 ] In the past, Asus firmwares would change the panel backlight directly through the EC when the display off hotkey (Fn+F7) was pressed, and only notify the OS of such change, with 0x33 when the LCD was ON and 0x34 when the LCD was OFF. These are currently mapped to KEY_DISPLAYTOGGLE and KEY_DISPLAY_OFF, respectively. Most recently the EC on Asus most machines lost ability to toggle the LCD backlight directly, but unless the OS informs the firmware it is going to handle the display toggle hotkey events, the firmware still tries change the brightness through the EC, to no effect. The end result is a long list (at Endless we counted 11) of Asus laptop models where the display toggle hotkey does not perform any action. Our firmware engineers contacts at Asus were surprised that there were still machines out there with the old behavior. Calling WMNB(ASUS_WMI_DEVID_BACKLIGHT==0x00050011, 2) on the _WDG device tells the firmware that it should let the OS handle the display toggle event, in which case it will simply notify the OS of a key press with 0x35, as shown by the DSDT excerpts bellow.

2018-11-27platform/x86: intel_telemetry: report debugfs failureRajneesh Bhardwaj
[ Upstream commit 8d98b1ef368feeb7720b8b9b6f3bd93f2ad892bc ] On some Goldmont based systems such as ASRock J3455M the BIOS may not enable the IPC1 device that provides access to the PMC and PUNIT. In such scenarios, the IOSS and PSS resources from the platform device can not be obtained and result in a invalid telemetry_plt_config which is an internal data structure that holds platform config and is maintained by the telemetry platform driver. This is also applicable to the platforms where the BIOS supports IPC1 device under debug configurations but IPC1 is disabled by user or the policy. This change allows user to know the reason for not seeing entries under /sys/kernel/debug/telemetry/* when there is no apparent failure at boot.

[ Upstream commit f9ac89f5ad613b462339e845aeb8494646fd9be2 ] The 98d610c3739a patch was introduced since v4.11-rc1 that it causes that the accelerometer input device will not be created on workable machines because the HID string comparing logic is wrong. And, the patch doesn't prevent that the accelerometer input device be created on the machines that have no BST0001. That's because the acpi_get_devices() returns success even it didn't find any match device. This patch fixed the HID string comparing logic of BST0001 device. And, it also makes sure that the acpi_get_devices() returns acpi_handle for BST0001.

2018-01-17platform/x86: wmi: Call acpi_wmi_init() laterRafael J. Wysocki
commit 98b8e4e5c17bf87c1b18ed929472051dab39878c upstream. Calling acpi_wmi_init() at the subsys_initcall() level causes ordering issues to appear on some systems and they are difficult to reproduce, because there is no guaranteed ordering between subsys_initcall() calls, so they may occur in different orders on different systems. In particular, commit 86d9f48534e8 (mm/slab: fix kmemcg cache creation delayed issue) exposed one of these issues where genl_init() and acpi_wmi_init() are both called at the same initcall level, but the former must run before the latter so as to avoid a NULL pointer dereference. For this reason, move the acpi_wmi_init() invocation to the initcall_sync level which should still be early enough for things to work correctly in the WMI land.

commit bff5bf9db1c9453ffd0a78abed3e2d040c092fd9 upstream. Sending the switch state change twice within the same frame is invalid evdev protocol and only works if the client handles keys immediately as well. Processing events immediately is incorrect, it forces a fake order of events that does not exist on the device. Recent versions of libinput changed to only process the device state and SYN_REPORT time, so now the key event is lost. https://bugs.freedesktop.org/show_bug.cgi?id=104041 Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Darren Hart (VMware) <dvhart@infradead.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

[ Upstream commit 163ca80013aafb6dc9cb295de3db7aeab9ab43f8 ] Added support for HP ProBook 440 G4 laptops by including the accelerometer orientation quirk for that device. Testing was performed based on the axis orientation guidelines here: https://www.kernel.org/doc/Documentation/misc-devices/lis3lv02d which states "If the left side is elevated, X increases (becomes positive)". When tested, on lifting the left edge, x values became increasingly negative thus indicating an inverted x-axis on the installed lis3lv02d chip. This was compensated by adding an entry for this device in hp_accel.c specifying the quirk as x_inverted. The patch was tested on a ProBook 440 G4 device and x-axis as well as y and z-axis values are now generated as per spec.

commit 298747b7579f5bbbced793d997b333fd10a24921 upstream. The current driver code is not checking for the error values returned by 'hp_wmi_dock_state()' and 'hp_wmi_tablet_state()' before passing the returned values down to 'input_report_switch()'. This error code is being translated to '1' in the input subsystem, reporting the wrong status. The biggest problem caused by this issue is that several laptops are wrongly reported by the driver as docked, preventing them to be put to sleep using the LID (and in most cases they are not even dockable). With this patch we create the report switches only if we are able to read the dock and tablet mode status correctly from ACPI.

2017-07-05platform/x86: ideapad-laptop: handle ACPI event 1Zach Ploskey
[ Upstream commit cfee5d63767b2e7997c1f36420d008abbe61565c ] On Ideapad laptops, ACPI event 1 is currently not handled. Many models log "ideapad_laptop: Unknown event: 1" every 20 seconds or so while running on battery power. Some convertible laptops receive this event when switching in and out of tablet mode. This adds and additional case for event 1 in ideapad_acpi_notify to call ideapad_input_report(priv, vpc_bit), so that the event is reported to userspace and we avoid unnecessary logging.

2017-04-21platform/x86: acer-wmi: setup accelerometer when machine has appropriate ↵Lee, Chun-Yi
notify event commit 98d610c3739ac354319a6590b915f4624d9151e6 upstream. The accelerometer event relies on the ACERWMID_EVENT_GUID notify. So, this patch changes the codes to setup accelerometer input device when detected ACERWMID_EVENT_GUID. It avoids that the accel input device created on every Acer machines. In addition, patch adds a clearly parsing logic of accelerometer hid to acer_wmi_get_handle_cb callback function. It is positive matching the "SENR" name with "BST0001" device to avoid non-supported hardware.

2017-04-12platform/x86: asus-wmi: Detect quirk_no_rfkill from the DSDTJoão Paulo Rechi Vita
[ Upstream commit 71050ae7bf83e4d71a859257d11adc5de517073e ] Some Asus laptops that have an airplane-mode indicator LED, also have the WMI WLAN user bit set, and the following bits in their DSDT: Scope (_SB) { (...) Device (ATKD) { (...) Method (WMNB, 3, Serialized) { (...) If (LEqual (IIA0, 0x00010002)) { OWGD (IIA1) Return (One) } } } } So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the wlan state, it drives the airplane-mode indicator LED (through the call to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF (since wlan is ON), and vice-versa. This commit skips registering RFKill switches at all for these laptops, to allow the asus-wireless driver to drive the airplane mode LED correctly through the ASHS ACPI device. Relying on the presence of ASHS and ASUS_WMI_DSTS_USER_BIT avoids adding DMI-based quirks for at least 21 different laptops.

2017-04-12platform/x86: acer-wmi: Only supports AMW0_GUID1 on acer familyLee, Chun-Yi
[ Upstream commit 5241b1938a4d33eee3d3b43f23067c8e5b96db45 ] The AMW0_GUID1 wmi is not only found on Acer family but also other machines like Lenovo, Fujitsu and Medion. In the past, acer-wmi handled those non-Acer machines by quirks list. But actually acer-wmi driver was loaded on any machine that had AMW0_GUID1. This behavior is strange because those machines should be supported by appropriate wmi drivers. e.g. fujitsu-laptop, ideapad-laptop. This patch adds the logic to check the machine that has AMW0_GUID1 should be in Acer/Packard Bell/Gateway white list. But, it still keeps the quirk list of those supported non-acer machines for backward compatibility.

callbacks commit a608a9d52fa4168efd478d684039ed545a69dbcd upstream. All LED-setting functions in fujitsu-laptop are currently assigned to the brightness_set callback, which is incorrect because they can sleep (due to their use of call_fext_func(), which in turn issues ACPI calls) and the documentation (in include/linux/leds.h) clearly states they must not. Assign them to brightness_set_blocking instead and change them to match the expected function prototype. This change makes it possible to use Fujitsu-specific LEDs with "heavy" triggers, like disk-activity or phy0rx.

We have a couple of drivers, acpi_apd.c and acpi_lpss.c, that need to pass extra build-in properties to the devices they create. Previously the drivers added those properties to the struct device which is member of the struct acpi_device, but that does not work. Those properties need to be assigned to the struct device of the platform device instead in order for them to become available to the drivers. To fix this, this patch changes acpi_create_platform_device function to take struct property_entry pointer as parameter.
