platform/x86: intel_scu_ipcutil: Remove default y from Kconfig

2020-01-22T16:52:06+00:00

This driver is by no means essential for system to boot up so remove default y from it. Signed-off-by: Mika Westerberg Reviewed-by: Andy Shevchenko Signed-off-by: Andy Shevchenko

platform/x86: Add support for Uncore frequency control

2020-01-13T19:02:36+00:00

Some server users set limits on the uncore frequency using MSR 620H, while running latency sensitive workloads. Here uncore frequency controls RING/LLC(last-level cache) clocks. But MSR control is not always possible from the user space, so this driver provides a sysfs interface to set max and min frequency limits. This MSR 620H is a die scoped in multi-die system or package scoped in non multi-die systems. When this driver is loaded, a new directory is created under /sys/devices/system/cpu. For example on a two package Skylake server: $cd /sys/devices/system/cpu/intel_uncore_frequency $ls package_00_die_00 package_01_die_00 $ls package_00_die_00 max_freq_khz min_freq_khz initial_max_freq_khz initial_min_freq_khz $grep . * max_freq_khz:2400000 min_freq_khz:1200000 initial_max_freq_khz:2400000 initial_min_freq_khz:1200000 Here, initial_max_freq_khz and initial_min_freq_khz are read only attributes to show power up or initial values of max and min frequencies respectively. Other attributes are read-write, so that users can modify. Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko

Merge tag 'docs-5.5a' of git://git.lwn.net/linux

2019-12-02T19:51:02+00:00

Pull Documentation updates from Jonathan Corbet: "Here are the main documentation changes for 5.5: - Various kerneldoc script enhancements. - More RST conversions; those are slowing down as we run out of things to convert, but we're a ways from done still. - Dan's "maintainer profile entry" work landed at last. Now we just need to get maintainers to fill in the profiles... - A reworking of the parallel build setup to work better with a variety of systems (and to not take over huge systems entirely in particular). - The MAINTAINERS file is now converted to RST during the build. Hopefully nobody ever tries to print this thing, or they will need to load a lot of paper. - A script and documentation making it easy for maintainers to add Link: tags at commit time. Also included is the removal of a bunch of spurious CR characters" * tag 'docs-5.5a' of git://git.lwn.net/linux: (91 commits) docs: remove a bunch of stray CRs docs: fix up the maintainer profile document libnvdimm, MAINTAINERS: Maintainer Entry Profile Maintainer Handbook: Maintainer Entry Profile MAINTAINERS: Reclaim the P: tag for Maintainer Entry Profile docs, parallelism: Rearrange how jobserver reservations are made docs, parallelism: Do not leak blocking mode to other readers docs, parallelism: Fix failure path and add comment Documentation: Remove bootmem_debug from kernel-parameters.txt Documentation: security: core.rst: fix warnings Documentation/process/howto/kokr: Update for 4.x -> 5.x versioning Documentation/translation: Use Korean for Korean translation title docs/memory-barriers.txt: Remove remaining references to mmiowb() docs/memory-barriers.txt/kokr: Update I/O section to be clearer about CPU vs thread docs/memory-barriers.txt/kokr: Fix style, spacing and grammar in I/O section Documentation/kokr: Kill all references to mmiowb() docs/memory-barriers.txt/kokr: Rewrite "KERNEL I/O BARRIER EFFECTS" section docs: Add initial documentation for devfreq Documentation: Document how to get links with git am docs: Add request_irq() documentation ...

platform/x86: intel_cht_int33fe: Split code to Micro-B and Type-C

2019-10-15T07:55:10+00:00

Existing intel_cht_int33fe ACPI pseudo-device driver assumes that hardware has Type-C connector and register related devices described as I2C connections in the _CRS resource. There is at least one hardware (Lenovo Yoga Book YB1-91L/F) with Micro-B USB connector exists. It has INT33FE device in the DSDT table but there are only two I2C connection described: PMIC and BQ27452 battery fuel gauge. Splitting existing INT33FE driver allow to maintain code for USB Micro-B (or AB) connector variant separately and make it simpler. Split driver to intel_cht_int33fe_common.c and intel_cht_int33fe_{microb,typec}.c. Compile all this sources to one .ko module to make user experience easier.

platform/x86: toshiba_acpi: do not select INPUT_POLLDEV

The driver does not use polling mode of input devices, and this config option is going away, so let's not reference it. Signed-off-by: Dmitry Torokhov Signed-off-by: Andy Shevchenko

platform/x86: peaq-wmi: switch to using polled mode of input devices

2019-10-15T07:55:09+00:00

We have added polled mode to the normal input devices with the intent of retiring input_polled_dev. This converts peaq-wmi driver to use the polling mode of standard input devices and removes dependency on INPUT_POLLDEV. Because the new polling coded does not allow peeking inside the poller structure to get the poll interval, we change the "debounce" process to operate on the time basis, instead of counting events. We also fix error handling during initialization, as previously we leaked input device structure when we failed to register it.
