Wysocki" To: Linux ACPI Cc: LKML , "Dumbre, Saket" Subject: [PATCH v1 04/26] ACPICA: Add UUIDs associated with TPM 2.0 devices Date: Wed, 14 Jan 2026 13:19:22 +0100 Message-ID: <2254685.irdbgypaU6@rafael.j.wysocki> Organization: Linux Kernel Development In-Reply-To: <12822121.O9o76ZdvQC@rafael.j.wysocki> References: <12822121.O9o76ZdvQC@rafael.j.wysocki> Precedence: bulk X-Mailing-List: linux-kernel@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset="utf-8" From: Armin Wolf The Trusted Computing Group has designed multiple interface extensions around TPM 2.0 devices including the ACPI start method, hardware information and memory clear features. Add the associated UUIDs to the list of known UUIDs so that the ASL compiler stops complaining about them.
