5a006121 - arm64: Move device scmi to std.arm

Wed, 25 Jan 2023 07:28:22 +0000

arm64: Move device scmi to std.armThe scmi driver in its current form requires the arm_doorbelldriver to communicate with the firmware.The arm_doorbell is only found in ARM Juno reference board (andapparently on Morello too).If we want to use scmi on other platform (like some rockchip or imxsoc), the driver needs to be updated to support svc/shmem communicationwith the firmware.For now since it can be only used with arm_doorbell move the device tostd.arm otherwise kernel configs like ALLWINNER or ROCKCHIP fails to build.Reviewed by: br, impSponsored by: Beckhoff Automation GmbH & Co.

54b96380 - Add support for ARM System Control and Management Interface (SCMI) v3.1.

Mon, 19 Dec 2022 20:16:18 +0000

Add support for ARM System Control and Management Interface (SCMI) v3.1.The SCMI specification describes a set of standard interfaces for power,performance and system management.SCMI is extensible and provides interfaces to access functions which areoften implemented in firmwares in the System Control Processor (SCP).This implements Shared Memory-based transfer, which is one of the ways onhow messages are exchanged between agents and the platform.This includes a driver for ARM Message Handling Unit (MHU) Doorbell, whichis a mechanism that the caller can use to alert the callee of the presenceof a message.The support implements clock management interface. For instance this allowsus to control HDMI pixel clock on ARM Morello Board.Tested on ARM Morello Board.Obtained from: CheriBSDDifferential Revision: https://reviews.freebsd.org/D37316Reviewed by: manuSponsored by: UKRI List of files: /freebsd-14.2/sys/arm64/conf/std.arm

0f2c6331 - arm64: Add per SoC family kernel config

Fri, 05 Feb 2021 20:41:06 +0000

arm64: Add per SoC family kernel configThere is multiple reason for this :- This makes it easier to see which driver is needed for each SoC- This makes it easier to create a custom config for one SoC- This really reduce boot time (which some people might want)Some explaination about the files :- std.arm64 contains all standard kernel option- std.dev contains all the standard kernel devices- std. contains all drivers needed to boot on this SoC family- includes std.arm64, std.dev and std.- GENERIC includes std.arm64, std.dev and all std.Sponsored by: Diablotin SystemsMFC After: 2 monthsReviewed by: mmel, cognet, impDifferential Revision: https://reviews.freebsd.org/D30474 List of files: /freebsd-14.2/sys/arm64/conf/std.arm
