Tue, 01 Sep 2026 19:48:05 +0200

firmware: coreboot: Add CFR firmware attributes drivercoreboot can publish a CFR tree in its coreboot table to describefirmware setup options. Add a firmware-attributes driver for that tableentry under the coreboot firmware driver directory.The driver exposes runtime EFI variable-backed boolean, enum and integersettings through the firmware-attributes ABI. It only registers settingswith readable runtime EFI variables, skips suppressed, volatile,dependency-gated and non-runtime options, and keeps read-only or inactiveoptions read-only in sysfs.For settings with an APM_CNT runtime-apply record, write the EFIvariable and ask firmware to apply the setting immediately with an I/Oport SMI command. If firmware reports a failure, restore the old EFIvariable value. Settings without a runtime apply hook keep the EFIvariable update and set pending_reboot. Depend on HAS_IOPORT becauseAPM_CNT uses legacy I/O ports.Tested on a Star Labs Byte with firmware 26.07: runtime APM_CNT applywas verified with power_led, and reboot-needed behavior was verified withdebug_level.Link: https://doc.coreboot.org/drivers/cfr.htmlLink: https://doc.coreboot.org/drivers/cfr_internal.htmlSigned-off-by: Sean Rhodes Link: https://lore.kernel.org/r/73204be94586622903da7fa90757fb091e8a7c2c.1788284852.git.sean@starlabs.systemsSigned-off-by: Tzung-Bi Shih List of files: /linux/drivers/firmware/coreboot/Makefile

44e33a5aaa2de3f5cf2701d6f4b0a7c63d4fe602 - firmware: Rename google firmware directory to coreboot

Tue, 01 Sep 2026 19:48:03 +0200

firmware: Rename google firmware directory to corebootMost drivers in drivers/firmware/google are coreboot table drivers ratherthan Google-specific firmware drivers. Rename the directory to corebootand update the Kconfig prompt, build path and maintainer entry.Rename the generic firmware Kconfig symbols to CONFIG_COREBOOT_* at thesame time so new configurations describe the firmware interface ratherthan one vendor. Keep the old CONFIG_GOOGLE_* names as transitionalsymbols so existing configurations keep selecting the same driversduring the rename.Leave defconfig updates to a separate patch so the configuration churnis easy to review independently.Suggested-by: Julius Werner Signed-off-by: Sean Rhodes Link: https://lore.kernel.org/r/0a81e0d8e15c13f6a65c45ce476e37b33564ad61.1788284852.git.sean@starlabs.systemsSigned-off-by: Tzung-Bi Shih List of files: /linux/drivers/firmware/coreboot/Makefile
