Some of the callbacks are similar to those - provided by the EFI runtime services page, but due to - historical reasons this different entry-point has been - used. - - The gsmi driver implements the kernel's abstraction for - these firmware callbacks. Currently, this functionality - is limited to handling the system event log and getting - access to EFI-style variables stored in nvram. - - Layout: - - /sys/firmware/gsmi/vars: - - This directory has the same layout (and - underlying implementation as /sys/firmware/efi/vars. - See Documentation/ABI/*/sysfs-firmware-efi-vars - for more information on how to interact with - this structure. - - /sys/firmware/gsmi/append_to_eventlog - write-only: - - This file takes a binary blob and passes it onto - the firmware to be timestamped and appended to - the system eventlog. The binary format is - interpreted by the firmware and may change from - platform to platform. The only kernel-enforced - requirement is that the blob be prefixed with a - 32bit host-endian type used as part of the - firmware call. - - /sys/firmware/gsmi/clear_config - write-only: - - Writing any value to this file will cause the - entire firmware configuration to be reset to - "factory defaults". Callers should assume that - a reboot is required for the configuration to be - cleared. - - /sys/firmware/gsmi/clear_eventlog - write-only: - - This file is used to clear out a portion/the - whole of the system event log. Values written - should be values between 1 and 100 inclusive (in - ASCII) representing the fraction of the log to - clear. Not all platforms support fractional - clearing though, and this writes to this file - will error out if the firmware doesn't like your - submitted fraction. - - Callers should assume that a reboot is needed - for this operation to complete. |
