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
