2024-07-25platform/x86: lg-laptop: Use ACPI device handle when evaluating WMAB/WMBBArmin Wolf
[ Upstream commit b27ea279556121b54d3f45d0529706cf100cdb3a ] On the LG Gram 16Z90S, the WMAB and WMBB ACPI methods are not mapped under \XINI, but instead are mapped under \_SB.XINI. The reason for this is that the LGEX0820 ACPI device used by this driver is mapped at \_SB.XINI, so the ACPI methods where moved as well to appear below the LGEX0820 ACPI device. Fix this by using the ACPI handle from the ACPI device when evaluating both methods.

2024-07-11platform/x86: toshiba_acpi: Fix quickstart quirk handlingArmin Wolf
commit e527a6127223b644e0a27b44f4b16e16eb6c7f0a upstream. The global hci_hotkey_quickstart quirk flag is tested in toshiba_acpi_enable_hotkeys() before the quirk flag is properly initialized based on SMBIOS data. This causes the quirk to be applied to all models, some of which behave erratically as a result. Fix this by initializing the global quirk flags during module initialization before registering the ACPI driver. This also allows us to mark toshiba_dmi_quirks[] as __initconst.

2024-06-27platform/x86: x86-android-tablets: Unregister devices in reverse orderHans de Goede
[ Upstream commit 3de0f2627ef849735f155c1818247f58404dddfe ] Not all subsystems support a device getting removed while there are still consumers of the device with a reference to the device. One example of this is the regulator subsystem. If a regulator gets unregistered while there are still drivers holding a reference a WARN() at drivers/regulator/core.c:5829 triggers, e.g.: WARNING: CPU: 1 PID: 1587 at drivers/regulator/core.c:5829 regulator_unregister Hardware name: Intel Corp. VALLEYVIEW C0 PLATFORM/BYT-T FFD8, BIOS BLADE_21.X64.0005.R00.1504101516 FFD8_X64_R_2015_04_10_1516 04/10/2015 RIP: 0010:regulator_unregister Call Trace: <TASK> regulator_unregister devres_release_group i2c_device_remove device_release_driver_internal bus_remove_device device_del device_unregister x86_android_tablet_remove On the Lenovo Yoga Tablet 2 series the bq24190 charger chip also provides a 5V boost converter output for powering USB devices connected to the micro USB port, the bq24190-charger driver exports this as a Vbus regulator. On the 830 (8") and 1050 ("10") models this regulator is controlled by a platform_device and x86_android_tablet_remove() removes platform_device-s before i2c_clients so the consumer gets removed first. But on the 1380 (13") model there is a lc824206xa micro-USB switch connected over I2C and the extcon driver for that controls the regulator. The bq24190 i2c-client *must* be registered first, because that creates the regulator with the lc824206xa listed as its consumer. If the regulator has not been registered yet the lc824206xa driver will end up getting a dummy regulator. Since in this case both the regulator provider and consumer are I2C devices, the only way to ensure that the consumer is unregistered first is to unregister the I2C devices in reverse order of in which they were created. For consistency and to avoid similar problems in the future change x86_android_tablet_remove() to unregister all device types in reverse order.

To enable them in that mode, a value between 1 and 7 must be used for HCI_HOTKEY_EVENT. Windows uses 0x5 on this laptop so use that for maximum predictability and compatibility.

[ Upstream commit 1981b296f858010eae409548fd297659b2cc570e ] When reading token data from sysfs on my Inspiron 3505, the token locations and values are wrong. This happens because match_attribute() blindly assumes that all entries in da_tokens have an associated entry in token_attrs. This however is not true as soon as da_tokens[] contains zeroed token entries. Those entries are being skipped when initialising token_attrs, breaking the core assumption of match_attribute(). Fix this by defining an extra struct for each pair of token attributes and use container_of() to retrieve token information. Tested on a Dell Inspiron 3050.

2024-04-08platform/x86: intel-vbtn: Update tablet mode switch at end of probeGwendal Grignou
ACER Vivobook Flip (TP401NAS) virtual intel switch is implemented as follow: Device (VGBI) { Name (_HID, EisaId ("INT33D6") ... Name (VBDS, Zero) Method (_STA, 0, Serialized) // _STA: Status ... Method (VBDL, 0, Serialized) { PB1E |= 0x20 VBDS |= 0x40 } Method (VGBS, 0, Serialized) { Return (VBDS) /* \_SB_.PCI0.SBRG.EC0_.VGBI.VBDS */ } ... } By default VBDS is set to 0. At boot it is set to clamshell (bit 6 set) only after method VBDL is executed. Since VBDL is now evaluated in the probe routine later, after the device is registered, the retrieved value of VBDS was still 0 ("tablet mode") when setting up the virtual switch. Make sure to evaluate VGBS after VBDL, to ensure the convertible boots in clamshell mode, the expected default.

2024-03-12platform/x86/intel/pmc: Improve PKGC residency counters debugKane Chen
The current code only prints PKGC-10 residency when the PKGC-10 is not reached in previous 'freeze' attempt. To debug PKGC-10 issues, we also need to know other PKGC residency counters to better triage issues. Ex: 1. When system is stuck in PC2, it can be caused short LTR from device. 2. When system is stuck in PC8, it can be caused by display engine. To better triage issues, all PKGC residency are needed when issues happen. Example log: CPU did not enter Package C10!!! (Package C10 cnt=0x0) Prev Package C2 cnt = 0x2191a325de, Current Package C2 cnt = 0x21aba30724 Prev Package C3 cnt = 0x0, Current Package C3 cnt = 0x0 Prev Package C6 cnt = 0x0, Current Package C6 cnt = 0x0 Prev Package C7 cnt = 0x0, Current Package C7 cnt = 0x0 Prev Package C8 cnt = 0x0, Current Package C8 cnt = 0x0 Prev Package C9 cnt = 0x0, Current Package C9 cnt = 0x0 Prev Package C10 cnt = 0x0, Current Package C10 cnt = 0x0 With this log, we can know whether it's a stuck PC2 issue, and we can check whether the short LTR from device causes the issue.

2024-03-12platform/x86: pmc_atom: Check state of PMC managed devices on s2idleJohannes Stezenbach
For the Bay Trail or Cherry Trail SoC to enter the S0i3 power-level at s2idle suspend requires most of the hw-blocks / devices in the SoC to be in D3 when entering s2idle suspend. If some devices are not in D3 then the SoC will stay in a higher power state, consuming much more power from the battery then in S0i3. Use the new acpi_s2idle_dev_ops and acpi_register_lps0_dev() functionality to register a new s2idle check function which checks that all hardware blocks in the South complex (controlled by the PMC) are in a state that allows the SoC to enter S0i3 and prints an error message for any device in D0. Some blocks are not used on lower-featured versions of the SoC and these blocks will always report being in D0 on SoCs were they are not used. A false-positive mask is used to identify these blocks and for blocks in this mask the error is turned into a debug message to avoid false-positive error messages. Note the pmc_atom code is enabled by CONFIG_X86_INTEL_LPSS which already depends on ACPI.
