Subject: [PATCH v6 0/2] Optimize tpm2_read_public() calls
Date: Sun, 7 Dec 2025 19:32:08 +0200 [thread overview]
Message-ID: <20251207173210.93765-1-jarkko@kernel.org> (raw)
The main goal is fairly straight-forwrd here.
The aim of these patches is optimize the number of tpm2_read_public()
calls to the bare minimum. The last patch is a bit out of scope but
I included because it builds on top of this work.
Jarkko Sakkinen (2):
KEYS: trusted: Re-orchestrate tpm2_read_public() calls
KEYS: trusted: Store parent's name to the encoded keys
