2020-07-07dptf: Add support for Running Average Power LimitsTim Wawrzynczak
This change adds support for emitting the PPCC table, which describes the ranges available as knobs for DPTF to tune. It can support min/max power, min/max time window for averaging, and the minimum adjustment size (granularity or step size) of each power limit. The current implementation only supports PL1 and PL2.

This change adds support for generating the _FPS table for the DPTF Fan object. The table describes different levels of fan activity that may be applied to the system in order to actively cool it. The information includes fan speed at a (rough) percentage level, fan speed in RPM, potential noise level in centibels, and power in mA.

2020-07-02acpi_device: Replace polarity with active_low in acpi_gpio for GpioIoFurquan Shaikh
As per ACPI spec, GpioIo does not have any polarity associated with it. Linux kernel uses `active_low` argument within GPIO _DSD property to allow BIOS to indicate if the corresponding GPIO should be treated as active low. Thus, if GPIO has active high polarity or if it does not have any polarity associated with it, then the `active_low` argument is supposed to be set to 0. Having a `polarity` field in acpi_gpio seems confusing because GPIOs might not always have polarity associated with them. Example, in case of DMIC-select GPIO where 0 means select DMIC0 and 1 means select DMIC1, there is no polarity associated with the GPIO. Thus, it would be clearer for mainboard to use macros without having to specify a particular polarity. In order to enable mainboards to provide GPIO information without polarity for GpioIo usage, this change also adds `ACPI_GPIO_OUTPUT` and `ACPI_GPIO_INPUT` macros.

Advertising SMI triggers in FADT is only valid if we exit with SMI installed. There has been some experiments to delay SMM installation to OS, yet there are new platforms that allow some configuration access only to be done inside SMM. Splitting static HAVE_SMI_HANDLER variable helps to manage cases where SMM might be both installed and cleared prior to entering payload.

2020-06-04acpi: Accomodate non-standard UUIDs in device propertiesDuncan Laurie
There have been changes to the way device properties are supported in Linux[1] and Windows[2] which add flexibilty: - non-standard UUIDs can be used instead of only ACPI_DP_UUID - support for multiple different packages within the _DSD that associate different properties with unique UUIDs. To handle this I extracted the part that does the write of UUID and properties to a separate function and defined a new PACKAGE type which has the custom UUID as a name and can be used the same way that child properties are today. For example a PCIe root port for a USB4 port has a standard property indicating the USB4 reference, and then two custom properties which are defined for different attributes. Example code: /* Create property table */ acpi_dp *dsd = acpi_dp_new_table("_DSD"); acpi_dp_add_reference(dsd, "usb4-port", usb4_path); /* Add package for hotplug */ acpi_dp *pkg = acpi_dp_new_table("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"); acpi_dp_add_integer(pkg, "HotPlugSupportInD3", 1); acpi_dp_add_package(dsd, pkg); /* Add package for external port info */ pkg = acpi_dp_new_table("efcc06cc-73ac-4bc3-bff0-76143807c389"); acpi_dp_add_integer(pkg, "ExternalFacingPort", 1); acpi_dp_add_package(dsd, pkg); /* Write all properties */ acpi_dp_write(dsd); Resulting ACPI: Scope (\_SB.PCI0.TRP0) { Name (_DSD, Package () { ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301") Package () { Package () { "usb4-port", \_SB.PCI0.TDM0.RHUB.PRTA } }, ToUUID ("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"), Package () { Package () { "HotPlugSupportInD3", One } }, ToUUID ("efcc06cc-73ac-4bc3-bff0-76143807c389"), Package () { Package () { "ExternalFacingPort", One }, } }) } [1] https://patchwork.kernel.org/patch/10599675/ [2] https://docs.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports Change-Id: I75f47825bf4ffc5e9e92af2c45790d1b5945576e Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/42047 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>

2020-05-21acpi/soundwire: Add functions to generate SoundWire propertiesDuncan Laurie
This change uses the previously added SoundWire definitions to provide functions that generate ACPI Device Properties for SoundWire controllers and codecs. A SoundWire controller driver should populate `struct soundwire_controller` and pass it to soundwire_gen_controller(). This will add all of the defined master links provided by the controller. A SoundWire codec driver should populate the necessary members in struct soundwire_codec and pass it to soundwire_gen_codec(). Several properties are optional and depend on whether the codec itself supports certain features and behaviors. The goal of this interface is to handle all of the properties defined in the SoundWire Discovery and Configuration Specification Version 1.0 so that controller and codec drivers do not need to all have code for writing standard properties. Both of these functions also provide a callback method for adding custom properties that are not defined by the SoundWire DisCo Specification. These properties may be required by OS drivers but are outside of the scope of the SoundWire specification itself. This code is tested with controller, codec, and mainboard implementations in subsequent commits.
