2024-04-29platform/x86: thinkpad_acpi: Switch to using sparse-keymap helpersHans de Goede
Switch the hotkey keymap handling over to the sparse-keymap helpers, there should be no functional changes from this. Note all the mappings to KEY_UNKNOWN are removed since that is the default behavior of sparse_keymap_report_event() for unknown scancodes. Also drop the big comment about making changes to the keymaps since the contents of that comment are mostly obsolete.

2024-04-29platform/x86: thinkpad_acpi: Drop KEY_RESERVED special handlingHans de Goede
The input core already filters out EV_KEY events for KEY_RESERVED, remove the check for this in tpacpi_input_send_key() and rely on the input core filtering instead. Also change tpacpi_input_send_key() to only report the scancode once instead of reporting it on both press and release. Together these 2 changes make tpacpi_input_send_key() behave the same as sparse_keymap_report_event(). The goal of this patch is to have a separate commit with the slightly different behavior from sparse_keymap_report_event() before switching over to using the sparse-keymap helpers.

2024-04-29platform/x86: thinkpad_acpi: Use correct keycodes for volume and brightness keysHans de Goede
Change the default keymap to report the correct keycodes for the volume and brightness keys. Reporting key events for these is already filtered out by the hotkey_reserved_mask which masks these keys out of hotkey_user_mask at initialization time, so there is no need to also map them to KEY_RESERVED. This avoids users, who want these to be reported, having to also remap the keycodes on top of overriding hotkey_user_mask to report these and Linux userspace has already been overriding the KEY_RESERVED mappings with the correct keycodes through udev/hwdb/60-keyboard.hwdb for years now. Also drop hotkey_unmap() it was only used to dynamically map the brightness keys to KEY_RESERVED and after removing that it has no remaining users.

2024-04-29platform/x86: thinkpad_acpi: Change hotkey_reserved_mask initializationHans de Goede
Change the hotkey_reserved_mask initialization to hardcode the list of reserved keys. There are only a few reserved keys and the code to iterate over the keymap will be removed when moving to sparse-keymaps. Note only the 32 original hotkeys are affected by the hotkey_*_mask values: if (i < sizeof(hotkey_reserved_mask)*8) hotkey_reserved_mask |= 1 << i; The (i < sizeof(hotkey_reserved_mask)*8) condition translates to (i < 32) so this code only ever set bits in hotkey_reserved_mask for the 32 original hotkeys. Therefor this patch does not set any bits in hotkey_reserved_mask for the KEY_RESERVED mappings for the adaptive keyboard scancodes.

2024-04-29platform/x86: thinkpad_acpi: Do not send ACPI netlink events for unknown hotkeysHans de Goede
Do not send ACPI netlink events for unknown hotkeys, to avoid userspace starting to rely on them. Instead these should be added to the keymap to send evdev events. This should not cause a behavior change for existing laptop models since all currently known 0x1xxx events have a mapping. In hindsight the ACPI netlink events should have been suppressed for the adaptive keyboard and extended hotkeys events too. But the kernel has been sending ACPI netlink events for those for a long time now, so we cannot just stop sending them without potentially causing issues for existing users who may depend on these.

tpacpi_input_send_key() All callers of tpacpi_input_send_key() first call tpacpi_driver_event(), move the tpacpi_driver_event() inside tpacpi_input_send_key() to avoid code duplication. For the original hotkey codes 0x1001 - 0x1020 tpacpi_driver_event() never returns true. So the added "return true;" inside tpacpi_input_send_key() never happens when called from tpacpi_hotkey_send_key() so behavior does not change.

This groups all the handling of hotkey events which do not emit a key press event together in tpacpi_driver_event(). This also drops the returning of false as known-event value when adaptive_keyboard_get_mode() / adaptive_keyboard_set_mode() fail. These functions already log an error on failure, returning false just leads to an extra messgae being logged about the hkey event being unknown, which is wrong as the event is not unknown.

Interrupt sources such as NMI or SMI are handled by retrying. Regular interrupts may occur frequently enough to prevent this operation from ever completing.

2024-04-15platform/x86: x86-android-tablets: Unregister devices in reverse orderHans de Goede
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.

2024-04-15platform/x86/amd/pmc: Add AMD MP2 STB functionalityBasavaraj Natikar
AMD MP2 STB function provides a data buffer used to log debug information about the system execution during S2Idle suspend/resume. A data buffer known as the STB (Smart Trace Buffer) is a circular buffer which is a low-level log to assist in debugging by providing insights into any potential hangs or stalls that may occur during the S2Idle suspend/resume processes. The current PMC driver retrieves STB data from MP1, but there can be scenarios where MP1 might hang or become unresponsive, leading to the loss of critical data present in the STB buffer. This defeats the purpose of the STB buffer, which was originally meant to help identify system failures. This feature creates stb_read_previous_boot debugfs allows users to retrieve the STB log from MP2 specifically from the last occurrence of the S2Idle suspend/resume. A userspace daemon can access STB log of last S2Idle suspend/resume which can help to troubleshoot potential issues related to hangs or stalls during the S2Idle suspend/resume sequence.
