| * | | | | platform/x86: intel-vbtn: Fix probe failure on devices with only switchesHans de Goede2020-05-071-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some devices the INT33D6 vbtn device is only used to report tablet-mode / docked status (switches) and there are no vbtn managed buttons. On these devices there is no VBDL object. Move the VBDL check to a intel_vbtn_has_buttons() helper and only exit from intel_vbtn_probe() with -ENODEV when there are both no buttons and no switches. Also only report the buttons being present to userspace if the has_buttons check has succeeded.

Some devices with a detachable keyboard and using the intel-vbnt (INT33D6) interface to report if they are in tablet mode (keyboard detached) or not, report 32 / "Detachable" as chassis-type, e.g. the HP Pavilion X2 series. Other devices with a detachable keyboard and using the intel-vbnt (INT33D6) interface to report SW_TABLET_MODE, report 8 / "Portable" as chassis-type. The Dell Venue 11 Pro 7130 is an example of this. Extend the DMI chassis-type check to also accept Portables and Detachables so that the intel-vbtn driver will report SW_TABLET_MODE on these devices. Note the chassis-type check was originally added to avoid a false-positive tablet-mode report on the Dell XPS 9360 laptop. To the best of my knowledge that laptop is using a chassis-type of 9 / "Laptop", so after this commit we still ignore the tablet-switch for that chassis-type.

But if we are not getting the initial status of the switch because the device does not have a tablet mode, then we really should not advertise the presence of a tablet-mode switch to userspace at all, as userspace may use the mere presence of this switch for certain heuristics.

SBL can be thought-of as fulfilling the role of a minimal BIOS implementation, i.e initializing the hardware and booting Operating System. Since SBL is not UEFI compliant, firmware update cannot be triggered using standard UEFI runtime services. Further considering performance impact, SBL doesn't look for a firmware update image on every reset and does so only when firmware update signal is asserted. SBL exposes an ACPI-WMI device which comes up in sysfs as /sys/bus/wmi/44FADEB1xxx and this driver adds a "firmware_update_request" device attribute. This attribute normally has a value of 0 and userspace can signal SBL to update firmware, on next reboot, by writing a value of 1 like: echo 1 > /sys/bus/wmi/devices/44FADEB1xxx/firmware_update_request This driver only implements a signaling mechanism, the actual firmware update process and various details like firmware update image format, firmware image location etc are defined by SBL and are not in the scope of this driver.

Both fans are controlled together as if they were a single fan. Tested on an X1 Extreme Gen1, an X1 Extreme Gen2, and a P50. The patch is defensive, it adds only specific supported machines, and falls back to the old behavior if both fans cannot be controlled. Background: I tested the BIOS default behavior on my X1E gen2 and both fans are always changed together. So rather than adding controls for each fan, this controls both fans together as the BIOS would do. This was inspired by a discussion on dual fan support for the thinkfan tool (see link below). All BIOS IDs are taken from there. The X1E gen2 ID is verified on my machine. Thanks to GitHub users voidworker and civic9 for the earlier patches and BIOS IDs, and to users peter-stoll and sassman for testing the patch on their machines.

This is pretty much what MFD subsystem is for so move the driver there, renaming it to intel_pmc_bxt.c which should be more clear what it is. MFD subsystem provides nice helper APIs for subdevice creation so convert the driver to use those. Unfortunately the ACPI device includes separate resources for most of the subdevices so we cannot simply call mfd_add_devices() to create all of them but instead we need to call it separately for each device. The new MFD driver continues to expose two sysfs attributes that allow userspace to send IPC commands to the PMC/SCU to avoid breaking any existing applications that may use these. Generally this is bad idea so document this in the ABI documentation.

This implements a new API that takes the SCU IPC instance as first parameter (NULL means the single instance is being used). The SCU IPC instance can be retrieved by calling new function intel_scu_ipc_dev_get() that take care of pinning the providing module in place as long as intel_scu_ipc_dev_put() is not called. The old API is updated to call the new API and is is left there in the legacy API header to support the existing users that cannot be converted easily. Subsequent patches will convert most of the users over to the new API.

This changes the driver to log command and subcommand with the error code which should make debugging easier. This also allows us to simplify the callers as they don't need to log these errors themselves.

| | * | | | | platform/x86: intel_scu_ipc: Split out SCU IPC functionality from the SCU driverMika Westerberg2020-04-244-65/+187

For example modern Intel CPUs include the same thing but now it is called PMC (Power Management Controller) instead of SCU. To make the IPC available for those split the driver into core part (intel_scu_ipc.c) and the SCU PCI driver part (intel_scu_pcidrv.c) which then calls the former before it goes and creates rest of the SCU devices. The SCU IPC will also register a new class that gets assigned to the device that is created under the parent PCI device. We also split the Kconfig symbols so that INTEL_SCU_IPC enables the SCU IPC library and INTEL_SCU_PCI the SCU driver and convert the users accordingly. While there remove default y from the INTEL_SCU_PCI symbol as it is already selected by X86_INTEL_MID.

They have detachable keyboards, so the hotkeys are send through a HID device (and handled by the hid-asus driver) and also the rfkill functionality is not used on these devices. Besides not adding any extra functionality, initializing the WMI interface on these devices actually has a negative side-effect. For some reason the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED, high and there is no (WMI or other) interface to drive this low again causing the LED to be permanently on, even during suspend. This commit adds a blacklist of DMI system_ids on which not to load the asus-nb-wmi and adds these Transformer books to this list. This fixes the webcam LED being permanently on under Linux.

The "dump_oops" module parameter and "dump-oops" Device Tree field are now considered deprecated, but are now automatically converted to their corresponding max_reason values when present, though the new max_reason setting has precedence. For struct ramoops_platform_data, the "dump_oops" member is entirely replaced by a new "max_reason" member, with the only existing user updated in place. Additionally remove the "reason" filter logic from ramoops_pstore_write(), as that is not specifically needed anymore, though technically this is a change in behavior for any ramoops users also setting the printk.always_kmsg_dump boot param, which will cause ramoops to behave as if max_reason was set to KMSG_DUMP_MAX.
