Subject: [PATCH v2 0/2] Add measurement and event log support for CC platforms
Date: Thu, 15 Feb 2024 03:00:00 +0000 [thread overview]
Message-ID: <20240215030002.281456-1-sathyanarayanan.kuppuswamy@linux.intel.com> (raw)
In a Confidential Computing (CC) environment, not all platforms
implement TPM support. Instead, it may support measurement and event
logging based upon the hardware Trusted Execution Environment (TEE)
capability. For such cases, UEFI specification [1] defines an
alternative measurement protocol and interfaces. This patch set
enables this support in EFI bootstub.
https://uefi.org/specs/UEFI/2.10/38_Confidential_Computing.html#efi-cc-measurement-protocol [1]
Changes since v1:
* Add missing tagged event data.
* Add support for get_event_log().
