Subject: [Patch v2 2/2] UefiCpuPkg/CpuS3DataDxe: Change Memory Type and address limitation.
Date: Wed, 8 Aug 2018 15:40:06 +0800 [thread overview]
Message-ID: <20180808074006.21360-2-eric.dong@intel.com> (raw)
In-Reply-To: <20180808074006.21360-1-eric.dong@intel.com>
Because CpuS3Data memory will be copy to smram at SmmReadToLock point,
so the memory type no need to be ACPI NVS type, also the address not
limit to below 4G.
This change remove the limit of ACPI NVS memory type and below 4G.
Pass OS boot and resume from S3 test.
