Subject: [edk2-devel] [PATCH V3 1/5] MdePkg: Add EFI_UNSUPPORTED return for some Runtime Service functions
Date: Fri, 2 Feb 2024 16:20:49 +0800 [thread overview]
Message-ID: <405208bb5a2b33da4de4a0e8a029f3baefc4940d.1706861638.git.suqiangx.ren@intel.com> (raw)
In-Reply-To: <cover.1706861638.git.suqiangx.ren@intel.com>
According to UEFI Spec 2.10 page 206, if any EFI_RUNTIME_SERVICES* calls
are not supported for use by the OS at runtime, an EFI_RT_PROPERTIES_TABLE
configuration table should be published describing which runtime services
are supported at runtime. So need to add EFI_UNSUPPORTED return for some
Runtime Service functions.
REF: UEFI spec 2.10 section 8 Services — Runtime Services
