( https://review.coreboot.org/c/coreboot/+/37994 ) Change subject: mb/google/peppy: Add ALS as ACPI device Some of models of the C720 can have an ISL29018 ambient light sensor on the mainboard, probably all the C720P have it. ...................................................................... mb/google/peppy: Add ALS as ACPI device Some of models of the C720 can have an ISL29018 ambient light sensor on the mainboard, probably all the C720P have it. This patch will provide a way for the kernel to access the ALS sensor even after the chromeos_laptop driver broke. Please note that this patch advertise the ALS as an ISL29023, this is due to the fact that the proximity function of the ISL2018 is available only if a properly IR LED is present with the sensor. The C720 doesn't have the IR LED circuit. More work will be required to properly set the _STA to help the kernel driver on probing of the device itself.

Change in coreboot[master]: Fixed configuration for DDR Size discovered by Coreboot

Marc Karasek has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/38904 ) Change subject: Fixed configuration for DDR Size discovered by Coreboot ...................................................................... Fixed configuration for DDR Size discovered by Coreboot For qemu-riscv value was incorrect. It was set to 32768 which in turn was being used as 32768MB (32+GB), instead of the 32MB it was intended to represent. Change value so it is a select option based on in menuconfig based on what you want coreboot to "discover" on boot. Current three options are : 128MB 256MB 512MB NOTE: You must specify greater than what is chosen from the above items on the qemu cmdline.

However, the ACPI specification provides +no generic mechanism for operating systems to interact with these platform +interfaces. This has led to a proliferation of vendor-specific control +mechanisms. Coreboot ports to existing platforms tend to mimic those +interfaces and make use of existing drivers, but this doesn't solve the +problem for devices where coreboot is the primary firmware implementation. + +This specification defines an ACPI device that exposes an interface for +controlling any radios defined by the platform. It is intended to allow for +generic OS drivers to be written which will then work on any coreboot +platform that implements this specification. + +## Device specification + +The coreboot rfkill device must be declared with a _HID of "BOOT0001". +It must implement the following ACPI methods: + +### DEVS + +This method provides a list of the supported radios whose state can be +controlledvia this device. It takes no arguments and returns a single +integer. The integer is a bitmask of radio types supported by the device, +defined as follows: + +| Bit | Radio type | +|-----|---------------| +| 0 | Wifi | +| 1 | Bluetooth | +| 2 | Ultra-Wideband| +| 3 | WiMax | +| 4 | WWAN | +| 5 | GPS | +| 6 | FM | +| 7 | NFC | + +### SSTA + +This defines the mutable ("soft") state of all radios in the system. This +method takes no arguments and returns a single integer. The integer is a +bitmask representing radio state using the same values as defined in +DEVS. If a bit is 1 then the radio is enabled. If a bit is 0 then the radio +is not present. If a bit is not set in the value returned by the DEVS method +then the meaning of the bit returned by SSTA is undefined. The state +returned by SSTA can be overridden by the CNTL method. + +### HSTA + +This defines the immutable ("hard") state of all radios in the system. This +method takes no arguments and returns a single integer. The integer is a +bitmask representing radio state using the same values as defined in +DEVS. If a bit is 1 then the radio is enabled. If a bit is 0 then the radio +is disabled. If a bit is not set in the value returned by the DEVS method +then the meaning of the bit returned by HSTA is undefined. The state +returned by HSTA cannot be overridden by the CNTL method. + +### CNTL + +This method takes a single integer as an argument and returns nothing. The +argument is a bitmask representing radio state using the same values as +defined in DEVS. If a bit is 1 then the platform should enable the +corresponding radio. If a bit is 0 then the platform should disable the +corresponding radio. This method only alters the soft radio state, not the +hard radio state. + +### Notifications + +The platform will send a Notify with a value of 0x80 if the state is updated +via any mechanism other than an OS request. The OS should then re-evaluate +the state by calling SSTA and HSTA. + +## Implementation design + +Two types of blocking are defined - "soft" and "hard". Soft state can be +overridden on request by the OS, for example in response to a hotkey +press. Hard state cannot be overridden by the OS, and should correspond to +cases where some external interface has requested that radios be disabled +(for example, a physical switch on the side of the device). Hard and soft +state should be tracked independently - for instance, if a radio is +currently enabled and then disabled via a physical switch being moved, the +state returned by SSTA should still indicate that the radio is enabled while +the state returned by HSTA should indicate that the radio is disabled. If +the OS then requests that the radio be disabled via the CNTL method, SSTA +and HSTA should now both indicate that the radio is disabled. If the +physical switch is now switched back, HSTA should indicate that the radio is +enabled but SSTA should still indicate that the radio is disabled. Only when +the OS requests that the radio be enabled via CNTL should the radio be +re-enabled. + +If the platform alters the radio state (in response to any form of policy +decision or in response to a physical switch), it should update the soft +block state (if the OS can override this decision) or the hard block state +(if the OS cannot override this decision) and then call Notify on the device +with an argument of 0x80. + +If the platform provides more than one radio of a given type, it should +implement an additional rfkill device. Each radio should only be represented +in a single device. + +If an rfkill device should be explicitly tied to a radio device, then the +radio should be exposed in the ACPI device heirarchy and an rfkill device +that controls only that radio implemented as a child of that device. diff --git a/src/arch/x86/include/arch/acpi.h b/src/arch/x86/include/arch/acpi.h index 68475c1..e87df04 100644 --- a/src/arch/x86/include/arch/acpi.h +++ b/src/arch/x86/include/arch/acpi.h @@ -64,6 +64,7 @@ /* List of ACPI HID that use the coreboot ACPI ID */ enum coreboot_acpi_ids { COREBOOT_ACPI_ID_CBTABLE = 0x0000, /* BOOT0000 */ + COREBOOT_ACPI_ID_RFKILL = 0x0001, /* BOOT0001 */ COREBOOT_ACPI_ID_MAX = 0xFFFF, /* BOOTFFFF */ }; -- To view, visit https://review.coreboot.org/c/coreboot/+/37991 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: coreboot Gerrit-Branch: master Gerrit-Change-Id: I94dc058825cb147aca0d007d68885d4bfbe580a8 Gerrit-Change-Number: 37991 Gerrit-PatchSet: 1 Gerrit-Owner: Matthew Garrett <mjg59(a)google.com> Gerrit-MessageType: newchange
