Hi Olivier, all DXE drivers load happens from second memory range (upper range). how to restrict to use only first memory range.
i want add multiple memory ranges so that uefi passes all memory info to Linux kernel. we dont want to load/run the DXE/drivers on secondary memory ranges, since it may be remote memory or memory on other node in numa context. thanks for your help. regards ganapat On Tue, Oct 14, 2014 at 7:45 PM, Olivier Martin <[email protected]> wrote: > Do you confirm you are using: > - MdeModulePkg/Universal/PCD/Pei/Pcd.inf > - MdeModulePkg/Universal/PCD/Dxe/Pcd.inf > >> -----Original Message----- >> From: Ganapatrao Kulkarni [mailto:[email protected]] >> Sent: 14 October 2014 14:47 >> To: [email protected] >> Subject: Re: [edk2] how to manage multiple dram memory ranges >> >> On Mon, Oct 13, 2014 at 7:14 PM, Olivier Martin >> <[email protected]> wrote: >> > It is possible to retrieve the memory from FDT.
