1c5fecb6 - efi: Export Runtime Configuration Interface table to sysfs

Wed, 10 Jul 2019 18:59:15 +0000

efi: Export Runtime Configuration Interface table to sysfsSystem firmware advertises the address of the 'RuntimeConfiguration Interface table version 2 (RCI2)' viaan EFI Configuration Table entry. This code retrieves the RCI2table from the address and exports it to sysfs as a binaryattribute 'rci2' under /sys/firmware/efi/tables directory.The approach adopted is similar to the attribute 'DMI' under/sys/firmware/dmi/tables.RCI2 table contains BIOS HII in XML format and is used to populateBIOS setup page in Dell EMC OpenManage Server Administrator tool.The BIOS setup page contains BIOS tokens which can be configured.Signed-off-by: Narendra K Reviewed-by: Mario Limonciello Signed-off-by: Ard Biesheuvel List of files: /linux-6.15/Documentation/ABI/testing/sysfs-firmware-efi

efi: Add 'systab' information to Documentation/ABIIt's not clear right now that the order in which entries are displayedin /sys/firmware/efi/systab actually forms an ABI that userspace toolsrely upon.Document the ABI along with the userspace tool that cares.Suggested-by: Ard Biesheuvel Acked-by: Ard Biesheuvel Reviewed-by: Jean Delvare Cc: Leif Lindholm Cc: Ivan Khoronzhuk Signed-off-by: Matt Fleming List of files: /linux-6.15/Documentation/ABI/testing/sysfs-firmware-efi

efi: Export more EFI table variables to sysfsExport fw_vendor, runtime and config table physical addresses to/sys/firmware/efi/{fw_vendor,runtime,config_table} because kexec kernelsneed them.From EFI spec these 3 variables will be updated to virtual address afterentering virtual mode. But kernel startup code will need the physicaladdress.Signed-off-by: Dave Young Tested-by: Toshi Kani Signed-off-by: Matt Fleming List of files: /linux-6.15/Documentation/ABI/testing/sysfs-firmware-efi
