Subject: 回复: [edk2-devel] [PATCH v2 1/1] MdeModulePkg/AcpiTableDxe: PCD switch to avoid using ACPI reclaim memory
Date: Tue, 2 Apr 2024 09:26:12 +0800	[thread overview]
Message-ID: <018601da849c$bfd96130$3f8c2390$@byosoft.com.cn> (raw)
In-Reply-To: <DM4PR11MB5455FD4E480D5CE03F02E0E9973F2@DM4PR11MB5455.namprd11.prod.outlook.com>

Aaron:
  Per the specification, it is valid to publish all ACPI table in
EfiAcpiMemoryNVS. 
  So, I have no other comments for this patch. Reviewed-by: Liming Gao
<gaoliming@byosoft.com.cn>

Thanks
