| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On ACPI based tablets, the ACPI touchscreen node only contains info on the gpio and the irq, and is missing any info on the axis. This info is expected to be built into the tablet model specific version of the driver shipped with the os-image for the device.

| * platform/x86: Support Turbo Boost Max 3.0 for non HWP systemsSrinivas Pandruvada2017-02-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On platforms supporting Intel Turbo Boost Max Technology 3.0, the maximum turbo frequencies (turbo ratio) of some cores in a CPU package may be higher than the other cores in the same package. In that case, better performance can be achieved by making the scheduler prefer to run tasks on the CPUs with higher max turbo frequencies. On Intel® Broadwell Xeon systems, it is optional to turn on HWP (Hardware P-States). When HWP is not turned on, the BIOS doesn't present required CPPC (Collaborative Processor Performance Control) tables. This table is used to get the per CPU core maximum performance ratio and inform scheduler (in cpufreq/intel_pstate driver). On such systems the maximum performance ratio can be read via over clocking (OC) mailbox interface for each CPU. This interface is not architectural and can change for every model of processors. This driver reads maximum performance ratio of each CPU and set up the scheduler priority metrics. In this way scheduler can prefer CPU with higher performance to schedule tasks.

Rework logolamp_set() to properly handle them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Dell-smbios is a helper module, it serves no purpose on its own, so do not present it as an option to the user. Instead, select it automatically whenever a driver which needs it is selected. Also select DCDBAS as needed, instead of depending on it, so that the Dell driver options are always visible. As a clean-up, I removed the "default n" statements as they are not needed (n is the default default.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 3fca3d3d5075 ("platform-x86: intel_mid_thermal: add msic_thermal alias") added a "msic_thermal" entry to the driver's platform device ID table since that was the platform dev name registered in some platforms and the only dev in the platform table was "msic_sensor" (DRIVER_NAME). But then commit 634830704d80 ("x86/mid/thermal: Add msic_thermal alias") changed DRIVER_NAME from "msic_sensor" to "msic_thermal", and so there's now duplicated entries in the platform device ID table.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | The cros_ec driver is still active while the device is suspended. Besides that, it also tries to transfer data even after the I2C host had been suspended. This patch uses a simple flag to prevent this.

The whole concept of this is broken. Creating devices in an interrupt handler is beyond any point of sanity. Make it at least behave halfways sane so accidental users do not have to deal with a hard to debug lockup.

Many models log "ideapad_laptop: Unknown event: 1" every 20 seconds or so while running on battery power. Some convertible laptops receive this event when switching in and out of tablet mode. This adds and additional case for event 1 in ideapad_acpi_notify to call ideapad_input_report(priv, vpc_bit), so that the event is reported to userspace and we avoid unnecessary logging.
