Subject: [PATCH v2 0/1] arm64: CCA TSM module autoloading
Date: Mon, 2 Dec 2024 18:01:55 -0600 [thread overview]
Message-ID: <20241203000156.72451-1-jeremy.linton@arm.com> (raw)
The TSM module provides both guest identification as well as
attestation when a guest is run in CCA mode. Lets assure by creating a
dummy platform device that the module is automatically loaded during
boot. The TSM module will be loaded by udev daemon after it receives
the device addition event. Once it is in place it can be used earlier
in the boot process to say decrypt a LUKS rootfs.
v1->v2:
Various comment updates/variable renames
Add missing __maybe_unused to the platform_device_id
