Subject: 回复: [edk2-devel] [PATCH v2] BaseTools/GenFw: Enhance GenFw to support PRM GCC build
Date: Tue, 1 Mar 2022 09:51:53 +0800 [thread overview]
Message-ID: <02d701d82d0e$ecf682c0$c6e38840$@byosoft.com.cn> (raw)
In-Reply-To: <20220228011411.3450-1-lisa.huang@intel.com>
Lisa:
Please add BZ link for this patch.
And, if PRM option currently only supports DXE RUNTIME driver and X64
arch,
does GenFw report error message if PRM option is specified for other arch
or other module type?
Thanks
