platform/x86: p2sb: Move out of X86_PLATFORM_DEVICES dependency

2022-08-01T14:26:38Z

The P2SB library is used for various drivers, including server platforms. That's why the dependency on X86_PLATFORM_DEVICES seems superfluous.

platform/x86: Move AMD platform drivers to separate directory

2022-06-22T09:57:55Z

Currently, AMD supported platform drivers are grouped under generic "x86" folder structure. Move the current drivers (amd-pmc and amd_hsmp) to a separate directory. This would also mean the newer driver submissions to pdx86 subsystem in the future will also land in AMD specific directory.

platform/x86: Drop the PMC_ATOM Kconfig option

2022-06-12T12:41:22Z

The def_bool y PMC_ATOM Kconfig option provides a couple of symbols used by the code enabled by the X86_INTEL_LPSS option and it registers some clocks. These clocks are only registered on Bay Trail, Cherry Trail and Brasswell Intel SoCs and kernels targeting these SoCs must always have the X86_INTEL_LPSS option enabled otherwise many things will not work. Building the PMC_ATOM code on kernels which are not targeting the mentioned SoCs and which do not have the X86_INTEL_LPSS enabled is not useful. This means that we can simplify things by replacing the PMC_ATOM Kconfig option in Makefiles with X86_INTEL_LPSS and then drop the option.

platform/x86: Add AMD system management interface

2022-03-02T10:42:36Z

Recent Fam19h EPYC server line of processors from AMD support system management functionality via HSMP (Host System Management Port) interface. The Host System Management Port (HSMP) is an interface to provide OS-level software with access to system management functions via a set of mailbox registers. More details on the interface can be found in chapter "7 Host System Management Port (HSMP)" of the following PPR https://www.amd.com/system/files/TechDocs/55898_B1_pub_0.50.zip This patch adds new amd_hsmp module under the drivers/platforms/x86/ which creates miscdevice with an IOCTL interface to the user space. /dev/hsmp is for running the hsmp mailbox commands.

platform/x86: Add Asus TF103C dock driver

2022-01-05T11:06:19Z

Add a driver for the keyboard, touchpad and USB port of the keyboard dock for the Asus TF103C 2-in-1 tablet. This keyboard dock has its own I2C attached embedded controller and the keyboard and touchpad are also connected over I2C, instead of using the usual USB connection. This means that the keyboard dock requires this special driver to function.

platform/x86: x86-android-tablets: New driver for x86 Android tablets

2021-12-25T11:41:06Z

x86 tablets which ship with Android as (part of) the factory image typically have various problems with their DSDTs. The factory kernels shipped on these devices typically have device addresses and GPIOs hardcoded in the kernel, rather then specified in their DSDT. With the DSDT containing a random collection of devices which may or may not actually be present as well as missing devices which are actually present. This driver, which loads only on affected models based on DMI matching, adds DMI based instantiating of kernel devices for devices which are missing from the DSDT, fixing e.g. battery monitoring, touchpads and/or accelerometers not working. Note the Kconfig help text also refers to "various fixes" ATM there are no such fixes, but there are also known cases where entries are present in the DSDT but they contain bugs, such as missing/wrong GPIOs. The plan is to also add fixes for things like this here in the future. This is the least ugly option to get these devices to fully work and to do so without adding any extra code to the main kernel image (vmlinuz) when built as a module.

platform/x86: simatic-ipc: add main driver for Siemens devices

2021-12-23T17:09:06Z

This mainly implements detection of these devices and will allow secondary drivers to work on such machines. The identification is DMI-based with a vendor specific way to tell them apart in a reliable way. Drivers for LEDs and Watchdogs will follow to make use of that platform detection. There is also some code to allow secondary drivers to find GPIO memory, that needs to be in place because the pinctrl drivers do not come up.

platform/x86/intel: Remove X86_PLATFORM_DRIVERS_INTEL

2021-12-23T16:21:58Z

While introduction of this menu brings a nice view in the configuration tools, it brought more issues than solves, i.e. it prevents to locate files in the intel/ subfolder without touching non-related Kconfig dependencies elsewhere. Drop X86_PLATFORM_DRIVERS_INTEL altogether. Note, on x86 it's enabled by default and it's quite unlikely anybody wants to disable all of the modules in this submenu.
