Various pdx86 docs under Documentation/ABI/testing still use Mario's old, now defunct, <mario.limonciello@dell.com> address. Update the docs to point to either the new Dell.Client.Kernel@dell.com email alias for Dell specific drivers, or to Mario's new @outlook.com address for other drivers.

In Windows the ASUS Armory Crate program can enable or disable the dGPU via a WMI call. This functions much the same as various Linux methods in software where the dGPU is removed from the device tree. However the WMI call saves the state of dGPU (enabled or not) and this then changes the dGPU visibility in Linux with no way for Linux users to re-enable it. We expose the WMI method so users can see and change the dGPU ACPI state. Signed-off-by:

Unfortunately we have been unable to find a reliable way to detect if and how SW_TABLET_MODE reporting is supported, so we are relying on DMI quirks for this. Add a module-option to specify the SW_TABLET_MODE method so that this can be easily tested without needing to rebuild the kernel.

dell-smbios is depended on by dell-laptop and that has this same table + some extra entries for chassis-type 30, 31 and 32. Since dell-laptop will already auto-load based on the DMI table in there (which also is more complete) and since dell-laptop will then bring in the dell-smbios module, the only scenario I can think of where this DMI table inside dell-smbios-smm.c is useful is if users have the dell-laptop module disabled and they want to use the sysfs interface offered by dell-smbios-smm.c. But that is such a corner case, even requiring a custom kernel build, that it does not weigh up against having this duplicate table, which as the current state already shows can only grow stale. Users who do hit this corner-case can always explicitly modprobe / insmod the module. Cc: Mario Limonciello <mario.limonciello@outlook.com> Signed-off-by:

When numa is used to map CPU to PCI device, the optimized path to read from cached data is not working and still calls _isst_if_get_pci_dev(). The reason is that when caching the mapping, numa information is not available as it is read later. So move the assignment of isst_cpu_info[cpu].numa_node before calling _isst_if_get_pci_dev().

The gpiod_lookup_table.table passed to gpiod_add_lookup_table() must be terminated with an empty entry, add this. Note we have likely been getting away with this not being present because the GPIO lookup code first matches on the dev_id, causing most lookups to skip checking the table and the lookups which do check the table will find a matching entry before reaching the end. With that said, terminating these tables properly still is obviously the correct thing to do. Fixes: f8eb0235 ("x86: pcengines apuv2 gpio/leds/keys platform driver") Signed-off-by:

360 degree hinges devices with dual KIOX010A + KIOX020A accelerometers always have both a KIOX010A and a KIOX020A ACPI device (one for each accel). Theoretical some vendor may re-use some DSDT for a non-convertible stripping out just the KIOX020A ACPI device from the DSDT. Check that both ACPI devices are present to make the check more robust.

Various 360 degree hinges (yoga) style 2-in-1 devices use 2 accelerometers to allow the OS to determine the angle between the display and the base of the device. On Windows these are read by a special HingeAngleService process which calls undocumented ACPI methods, to let the firmware know if the 2-in-1 is in tablet- or laptop-mode. The firmware may use this to disable the kbd and touchpad to avoid spurious input in tablet-mode as well as to report SW_TABLET_MODE info to the OS. Since Linux does not call these undocumented methods, the SW_TABLET_MODE info reported by various pdx86 drivers is incorrect on these devices. Before this commit the intel-hid and thinkpad_acpi code already had 2 hardcoded checks for ACPI hardware-ids of dual-accel sensors to avoid reporting broken info. And now we also have a bug-report about the same problem in the intel-vbtn code. Since there are at least 3 different ACPI hardware-ids in play, add a new dual_accel_detect() helper which checks for all 3, rather then adding different hardware-ids to the drivers as bug-reports trickle in. Having shared code which checks all known hardware-ids is esp. important for the intel-hid and intel-vbtn drivers as these are generic drivers which are used on a lot of devices. The BOSC0200 hardware-id requires special handling, because often it is used for a single-accelerometer setup. Only in a few cases it refers to a dual-accel setup, in which case there will be 2 I2cSerialBus resources in the device's resource-list, so the helper checks for this.

tlmi_sysfs_init() calls tlmi_release_attr() on errors which calls kobject_put() for attributes created by tlmi_analyze(), but if we bail early because of an error, then this means that some of the kobjects will not have been initialized yet; and we should thus not call kobject_put() on them. Switch from using kobject_init_and_add() inside tlmi_sysfs_init() to initializing all the created kobjects directly in tlmi_analyze() and only adding them from tlmi_sysfs_init(). This way all kobjects will always be initialized when tlmi_release_attr() gets called. Signed-off-by:

Even the FCH SSC registers provides certain level of information about the s0ix entry and exit times which comes handy when the SMU fails to report the statistics via the mailbox communication. This information is captured via a new debugfs file "s0ix_stats". A non-zero entry in this counters would mean that the system entered the s0ix state. If s0ix entry time and exit time don't change during suspend to idle, the silicon has not entered the deepest state. Signed-off-by:

The protocol to submit a job request to SMU is to wait for AMD_PMC_REGISTER_RESPONSE to return 1,meaning SMU is ready to take requests. PMC driver has to make sure that the response code is always AMD_PMC_RESULT_OK before making any command submissions. When we submit a message to SMU, we have to wait until it processes the request. Adding a read_poll_timeout() check as this was missing in the existing code. Also, add a mutex to protect amd_pmc_send_cmd() calls to SMU.
