Subject: [edk2-devel] [PATCH v4 06/10] DynamicTablesPkg: Add PsdToken field to CM_ARM_GICC_INFO object
Date: Tue, 12 Dec 2023 10:28:43 +0100	[thread overview]
Message-ID: <20231212092847.1253756-7-pierre.gondois@arm.com> (raw)
In-Reply-To: <20231212092847.1253756-1-pierre.gondois@arm.com>

The _PSD object (cf. ACPI 6.5, s8.4.5.5 _PSD (P-State Dependency)
allows to describe CPU's power state dependencies. Add a PsdToken
field to the CM_ARM_GICC_INFO object so that interdependent CPUs
can reference the same CM_ARM_PSD_INFO object.

Signed-off-by: Pierre Gondois <pierre.gondois@arm.com>
