Description

Each operating system relies on the information exposed to it by the firmware. It consists of various data like memory map, device structure (either ACPI or devicetree), firmware version, vendor, etc. But passing information from operating system bootloader has been neglected for many years. In this presentation, we will mainly focus on retrieving information from firmware and bootloader by Linux kernel with a special focus on bootloader log and DRTM TPM event log.
