2024-02-20platform/x86: x86-android-tablets: Fix acer_b1_750_goodix_gpios nameHans de Goede1-2/+2
The Acer B1 750 tablet used a Novatek NVT-ts touchscreen, not a Goodix touchscreen. Rename acer_b1_750_goodix_gpios to acer_b1_750_nvt_ts_gpios to correctly reflect this. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/20240216201721.239791-5-hdegoede@redhat.com

After commit b286f4e87e32 ("serial: core: Move tty and serdev to be children of serial core port device") x86_instantiate_serdev() no longer works due to the serdev-controller-device moving in the device hierarchy from (e.g.) /sys/devices/pci0000:00/8086228A:00/serial0 to /sys/devices/pci0000:00/8086228A:00/8086228A:00:0/8086228A:00:0.0/serial0 Use the new get_serdev_controller() helper function to fix this.

2024-02-20platform/x86: Add new get_serdev_controller() helperHans de Goede1-0/+80
In some cases UART attached devices which require an in kernel driver, e.g. UART attached Bluetooth HCIs are described in the ACPI tables by an ACPI device with a broken or missing UartSerialBusV2() resource. This causes the kernel to create a /dev/ttyS# char-device for the UART instead of creating an in kernel serdev-controller + serdev-device pair for the in kernel driver. The quirk handling in acpi_quirk_skip_serdev_enumeration() makes the kernel create a serdev-controller device for these UARTs instead of a /dev/ttyS#. Instantiating the actual serdev-device to bind to is up to pdx86 code, so far this was handled by the x86-android-tablets code. But since commit b286f4e87e32 ("serial: core: Move tty and serdev to be children of serial core port device") the serdev-controller device has moved in the device hierarchy from (e.g.) /sys/devices/pci0000:00/8086228A:00/serial0 to /sys/devices/pci0000:00/8086228A:00/8086228A:00:0/8086228A:00:0.0/serial0 . This makes this a bit trickier to do and another driver is in the works which will also need this functionality. Add a new helper to get the serdev-controller device, so that the new code for this can be shared.

2024-02-20platform/x86: x86-android-tablets: Fix keyboard touchscreen on Lenovo ↵Hans de Goede3-0/+5
Yogabook1 X90 After commit 4014ae236b1d ("platform/x86: x86-android-tablets: Stop using gpiolib private APIs") the touchscreen in the keyboard half of the Lenovo Yogabook1 X90 stopped working with the following error: Goodix-TS i2c-goodix_ts: error -EBUSY: Failed to get irq GPIO The problem is that when getting the IRQ for instantiated i2c_client-s from a GPIO (rather then using an IRQ directly from the IOAPIC), x86_acpi_irq_helper_get() now properly requests the GPIO, which disallows other drivers from requesting it. Normally this is a good thing, but the goodix touchscreen also uses the IRQ as an output during reset to select which of its 2 possible I2C addresses should be used. Add a new free_gpio flag to struct x86_acpi_irq_data to deal with this and release the GPIO after getting the IRQ in this special case.

2024-02-19platform/x86: touchscreen_dmi: Allow partial (prefix) matches for ACPI namesHans de Goede1-2/+2
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.

2024-02-13platform/x86: wmi: Make input buffer mandatory when evaluating methodsArmin Wolf1-11/+10
The ACPI-WMI specification declares in the section "ACPI Control Method Naming Conventions and Functionality for Windows 2000 Instrumentation" that a WMxx control method takes 3 arguments: instance, method id and argument buffer. This is also the case even when the underlying WMI method does not have any input arguments. So if a WMI driver evaluates a WMI method without passing an input buffer, ACPICA will log a warning complaining that the third argument is missing. Prevent this by checking that a input buffer was passed, and return an error if this was not the case. Tested on a Asus PRIME B650-Plus.

2024-02-06platform/x86: hp-wmi: Add thermal profile support for 8BAD boardsAlexis Belmonte1-2/+59
Add 8BAD to the list of boards which have thermal profile selection available. This allows the CPU to draw more power than the default TDP barrier defined by the 'balanced' thermal profile (around 50W), hence allowing it to perform better without being throttled by the embedded controller (around 130W). We first need to set the HP_OMEN_EC_THERMAL_PROFILE_TIMER_OFFSET to zero. This prevents the timer countdown from reaching zero, making the embedded controller "force-switch" the system's thermal profile back to 'balanced' automatically. We also need to put a number of specific flags in HP_OMEN_EC_THERMAL_PROFILE_FLAGS_OFFSET when we're switching to another thermal profile: - for 'performance', we need to set both HP_OMEN_EC_FLAGS_TURBO and HP_OMEN_EC_FLAGS_NOTIMER; - for 'balanced' and 'powersave', we clear out the register to notify the system that we want to lower the TDP barrier as soon as possible. The third flag defined in the hp_thermal_profile_omen_flags enum, HP_OMEN_EC_FLAGS_JUSTSET, is present for completeness. To prevent potential behaviour breakage with other Omen models, a separate omen_timed_thermal_profile_boards array has been added to list which boards expose this behaviour. Performance benchmarking was done with the help of silver.urih.com and Google Chrome 120.0.6099.129, on Gnome 45.2, with the 'performance' thermal profile set: | | Performance | Stress | TDP | |------------------|-------------|------------|-------| | with my patch | P84549 | S0.1891 | 131W | | without my patch | P44084 | S0.1359 | 47W | The TDP measurements were done with the help of the s-tui utility, during the load. There is still work to be done: - tune the CPU and GPU fans to better cool down and enhance performance at the right time; right now, it seems that the fans are not properly reacting to thermal/performance events, which in turn either causes thermal throttling OR makes the fans spin way too long, even though the temperatures have lowered down - expose the CPU and GPU fan curves to user-land so that they can be controlled just like what the Omen Gaming Hub utility proposes to its users; Signed-off-by: Alexis Belmonte <alexbelm48@gmail.com> Link: https://lore.kernel.org/r/ZbucvX2rRdqRgtcu@alexis-pc Reviewed-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com> Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@linux.intel.com>

But since the class string is not initialized during probe, an empty string is being passed: netlink: PNP0C14:01 000000d0 00000000 Fix this by passing a static string instead. Tested on a Dell Inspiron 3505.

2024-01-31platform/x86/intel/ifs: Add an entry rendezvous for SAFAshok Raj1-22/+26
The activation for Scan at Field (SAF) includes a parameter to make microcode wait for both threads to join. It's preferable to perform an entry rendezvous before the activation to ensure that they start the `wrmsr` close enough to each other. In some cases it has been observed that one of the threads might be just a bit late to arrive. An entry rendezvous reduces the likelihood of these cases occurring. Add an entry rendezvous to ensure the activation on both threads happen close enough to each other.

2024-01-31platform/x86/intel/ifs: Replace the exit rendezvous with an entry rendezvous ↵Ashok Raj1-5/+4
for ARRAY_BIST ARRAY_BIST requires the test to be invoked only from one of the HT siblings of a core. If the other sibling was in mwait(), that didn't permit the test to complete and resulted in several retries before the test could finish. The exit rendezvous was introduced to keep the HT sibling busy until the primary CPU completed the test to avoid those retries. What is actually needed is to ensure that both the threads rendezvous *before* the wrmsr to trigger the test to give good chance to complete the test. The `stop_machine()` function returns only after all the CPUs complete running the function, and provides an exit rendezvous implicitly. In kernel/stop_machine.c::multi_cpu_stop(), every CPU in the mask needs to complete reaching MULTI_STOP_RUN. When all CPUs complete, the state machine moves to next state, i.e MULTI_STOP_EXIT. Thus the underlying API stop_core_cpuslocked() already provides an exit rendezvous. Add the rendezvous earlier in order to ensure the wrmsr is triggered after all CPUs reach the do_array_test(). Remove the exit rendezvous since stop_core_cpuslocked() already guarantees that.
