2024-08-19platform/chrome: cros_ec_proto: Lock device when updating MKBP versionPatryk Duda1-0/+2
commit df615907f1bf907260af01ccb904d0e9304b5278 upstream. The cros_ec_get_host_command_version_mask() function requires that the caller must have ec_dev->lock mutex before calling it. This requirement was not met and as a result it was possible that two commands were sent to the device at the same time. The problem was observed while using UART backend which doesn't use any additional locks, unlike SPI backend which locks the controller until response is received.

2024-03-06platform/x86: touchscreen_dmi: Allow partial (prefix) matches for ACPI namesHans de Goede1-2/+2
[ Upstream commit dbcbfd662a725641d118fb3ae5ffb7be4e3d0fb0 ] On some devices the ACPI name of the touchscreen is e.g. either MSSL1680:00 or MSSL1680:01 depending on the BIOS version. This happens for example on the "Chuwi Hi8 Air" tablet where the initial commit's ts_data uses "MSSL1680:00" but the tablets from the github issue and linux-hardware.org probe linked below both use "MSSL1680:01". Replace the strcmp() match on ts_data->acpi_name with a strstarts() check to allow using a partial match on just the ACPI HID of "MSSL1680" and change the ts_data->acpi_name for the "Chuwi Hi8 Air" accordingly to fix the touchscreen not working on models where it is "MSSL1680:01". Note this drops the length check for I2C_NAME_SIZE. This never was necessary since the ACPI names used are never more then 11 chars and I2C_NAME_SIZE is 20 so the replaced strncmp() would always stop long before reaching I2C_NAME_SIZE.

commit fdcc0602d64f22185f61c70747214b630049cc33 upstream. Commit 1ea0d3b46798 ("platform/x86: asus-wmi: Simplify tablet-mode-switch handling") unified the asus-wmi tablet-switch handling, but it did not take into account that the value returned for the kbd_dock_devid WMI method is inverted where as the other ones are not inverted. This causes asus-wmi to report an inverted tablet-switch state for devices which use the kbd_dock_devid, which causes libinput to ignore touchpad events while the affected T10x model 2-in-1s are docked. Add inverting of the return value in the kbd_dock_devid case to fix this.

2023-12-13mlxbf-bootctl: correctly identify secure boot with development keysDavid Thompson1-13/+26
[ Upstream commit d4eef75279f5e9d594f5785502038c763ce42268 ] The secure boot state of the BlueField SoC is represented by two bits: 0 = production state 1 = secure boot enabled 2 = non-secure (secure boot disabled) 3 = RMA state There is also a single bit to indicate whether production keys or development keys are being used when secure boot is enabled. This single bit (specified by MLXBF_BOOTCTL_SB_DEV_MASK) only has meaning if secure boot state equals 1 (secure boot enabled). The secure boot states are as follows: - “GA secured” is when secure boot is enabled with official production keys. - “Secured (development)” is when secure boot is enabled with development keys. Without this fix “GA Secured” is displayed on development cards which is misleading. This patch updates the logic in "lifecycle_state_show()" to handle the case where the SoC is configured for secure boot and is using development keys.

[ Upstream commit 98829e84dc67630efb7de675f0a70066620468a3 ] 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: Luke D.

2023-12-13platform/x86: asus-wmi: Add support for SW_TABLET_MODE on UX360Samuel Čavoj3-0/+56
[ Upstream commit ea856ec266c1e6aecd2b107032d5b5d661f0686d ] The UX360CA has a WMI device id 0x00060062, which reports whether the lid is flipped in tablet mode (1) or in normal laptop mode (0). Add a quirk (quirk_asus_use_lid_flip_devid) for devices on which this WMI device should be used to figure out the SW_TABLET_MODE state, as opposed to the quirk_asus_use_kbd_dock_devid. Additionally, the device needs to be queried on resume and restore because the firmware does not generate an event if the laptop is put to sleep while in tablet mode, flipped to normal mode, and later awoken. It is assumed other UX360* models have the same WMI device. As such, the quirk is applied to devices with DMI_MATCH(DMI_PRODUCT_NAME, "UX360"). More devices with this feature need to be tested and added accordingly. The reason for using an allowlist via the quirk mechanism is that the new WMI device (0x00060062) is also present on some models which do not have a 360 degree hinge (at least FX503VD and GL503VD from Hans' DSTS collection) and therefore its presence cannot be relied on.

[ Upstream commit eba9ac7abab91c8f6d351460239108bef5e7a0b6 ] Since commit fa1f68db6ca7 ("drivers: misc: pass miscdevice pointer via file private data"), the miscdevice stores a pointer to itself inside filp->private_data, which means that private_data will not be NULL when wmi_char_open() is called. This might cause memory corruption should wmi_char_open() be unable to find its driver, something which can happen when the associated WMI device is deleted in wmi_free_devices(). Fix the problem by using the miscdevice pointer to retrieve the WMI device data associated with a char device using container_of().

Newer Asus laptops send the following new WMI event codes when some of the F1 - F12 "media" hotkeys are pressed: 0x2a Screen Capture 0x2b PrintScreen 0x2c CapsLock Map 0x2a to KEY_SELECTIVE_SCREENSHOT mirroring how similar hotkeys are mapped on other laptops. PrintScreem and CapsLock are also reported as normal PS/2 keyboard events, map these event codes to KE_IGNORE to avoid "Unknown key code 0x%x\n" log messages.

2023-10-25platform/x86: asus-wmi: Change ASUS_WMI_BRN_DOWN code from 0x20 to 0x2eHans de Goede1-1/+1
commit f37cc2fc277b371fc491890afb7d8a26e36bb3a1 upstream. Older Asus laptops change the backlight level themselves and then send WMI events with different codes for different backlight levels. The asus-wmi.c code maps the entire range of codes reported on brightness down keypresses to an internal ASUS_WMI_BRN_DOWN code: define NOTIFY_BRNUP_MIN 0x11 define NOTIFY_BRNUP_MAX 0x1f define NOTIFY_BRNDOWN_MIN 0x20 define NOTIFY_BRNDOWN_MAX 0x2e if (code >= NOTIFY_BRNUP_MIN && code <= NOTIFY_BRNUP_MAX) code = ASUS_WMI_BRN_UP; else if (code >= NOTIFY_BRNDOWN_MIN && code <= NOTIFY_BRNDOWN_MAX) code = ASUS_WMI_BRN_DOWN; Before this commit all the NOTIFY_BRNDOWN_MIN - NOTIFY_BRNDOWN_MAX aka 0x20 - 0x2e events were mapped to 0x20. This mapping is causing issues on new laptop models which actually send 0x2b events for printscreen presses and 0x2c events for capslock presses, which get translated into spurious brightness-down presses. The plan is disable the 0x11-0x2e special mapping on laptops where asus-wmi does not register a backlight-device to avoid the spurious brightness-down keypresses. New laptops always send 0x2e for brightness-down presses, change the special internal ASUS_WMI_BRN_DOWN value from 0x20 to 0x2e to match this in preparation for fixing the spurious brightness-down presses. This change does not have any functional impact since all of 0x20 - 0x2e is mapped to ASUS_WMI_BRN_DOWN first and only then checked against the keymap code and the new 0x2e value is still in the 0x20 - 0x2e range.

2023-10-10platform/x86: intel_scu_ipc: Fail IPC send if still busyStephen Boyd1-12/+28
[ Upstream commit 85e654c9f722853a595fa941dca60c157b707b86 ] It's possible for interrupts to get significantly delayed to the point that callers of intel_scu_ipc_dev_command() and friends can call the function once, hit a timeout, and call it again while the interrupt still hasn't been processed. This driver will get seriously confused if the interrupt is finally processed after the second IPC has been sent with ipc_command(). It won't know which IPC has been completed. This could be quite disastrous if calling code assumes something has happened upon return from intel_scu_ipc_dev_simple_command() when it actually hasn't. Let's avoid this scenario by simply returning -EBUSY in this case. Hopefully higher layers will know to back off or fail gracefully when this happens. It's all highly unlikely anyway, but it's better to be correct here as we have no way to know which IPC the status register is telling us about if we send a second IPC while the previous IPC is still processing.

ipc_wait_for_interrupt() [ Upstream commit 427fada620733e6474d783ae6037a66eae42bf8c ] It's possible for the completion in ipc_wait_for_interrupt() to timeout, simply because the interrupt was delayed in being processed. A timeout in itself is not an error. This driver should check the status register upon a timeout to ensure that scheduling or interrupt processing delays don't affect the outcome of the IPC return value. CPU0 SCU ---- --- ipc_wait_for_interrupt() wait_for_completion_timeout(&scu->cmd_complete) [TIMEOUT] status[IPC_STATUS_BUSY]=0 Fix this problem by reading the status bit in all cases, regardless of the timeout. If the completion times out, we'll assume the problem was that the IPC_STATUS_BUSY bit was still set, but if the status bit is cleared in the meantime we know that we hit some scheduling delay and we should just check the error bit.

2023-10-10platform/x86: intel_scu_ipc: Check status after timeout in busy_loop()Stephen Boyd1-11/+8
[ Upstream commit e0b4ab3bb92bda8d12f55842614362989d5b2cb3 ] It's possible for the polling loop in busy_loop() to get scheduled away for a long time. status = ipc_read_status(scu); // status = IPC_STATUS_BUSY <long time scheduled away> if (!(status & IPC_STATUS_BUSY)) If this happens, then the status bit could change while the task is scheduled away and this function would never read the status again after timing out. Instead, the function will return -ETIMEDOUT when it's possible that scheduling didn't work out and the status bit was cleared. Bit polling code should always check the bit being polled one more time after the timeout in case this happens. Fix this by reading the status once more after the while loop breaks. The readl_poll_timeout() macro implements all of this, and it is shorter, so use that macro here to consolidate code and fix this. There were some concerns with using readl_poll_timeout() because it uses timekeeping, and timekeeping isn't running early on or during the late stages of system suspend or early stages of system resume, but an audit of the code concluded that this code isn't called during those times so it is safe to use the macro.

2023-08-11platform/x86: msi-laptop: Fix rfkill out-of-sync on MSI Wind U100Maxim Mikityanskiy1-4/+4
[ Upstream commit ad084a6d99bc182bf109c190c808e2ea073ec57b ] Only the HW rfkill state is toggled on laptops with quirks->ec_read_only (so far only MSI Wind U90/U100). There are, however, a few issues with the implementation: 1. The initial HW state is always unblocked, regardless of the actual state on boot, because msi_init_rfkill only sets the SW state, regardless of ec_read_only. 2. The initial SW state corresponds to the actual state on boot, but it can't be changed afterwards, because set_device_state returns -EOPNOTSUPP. It confuses the userspace, making Wi-Fi and/or Bluetooth unusable if it was blocked on boot, and breaking the airplane mode if the rfkill was unblocked on boot. Address the above issues by properly initializing the HW state on ec_read_only laptops and by allowing the userspace to toggle the SW state. Don't set the SW state ourselves and let the userspace fully control it. Toggling the SW state is a no-op, however, it allows the userspace to properly toggle the airplane mode. The actual SW radio disablement is handled by the corresponding rtl818x_pci and btusb drivers that have their own rfkills. Tested on MSI Wind U100 Plus, BIOS ver 1.0G, EC ver 130.

[ Upstream commit b20cf3f89c56b5f6a38b7f76a8128bf9f291bbd3 ] It is possible to peep kernel page's data by providing larger `insize` in struct cros_ec_command[1] when invoking EC host commands. Fix it by using zeroed memory.

2023-03-17platform: x86: MLX_PLATFORM: select REGMAP instead of depending on itRandy Dunlap1-1/+2
[ Upstream commit 7e7e1541c91615e9950d0b96bcd1806d297e970e ] REGMAP is a hidden (not user visible) symbol. Users cannot set it directly thru "make *config", so drivers should select it instead of depending on it if they need it. Consistently using "select" or "depends on" can also help reduce Kconfig circular dependency issues. Therefore, change the use of "depends on REGMAP" to "select REGMAP".
