Date: Thu, 12 Aug 2021 01:30:50 -0500 From: Alex Sierra <alex.sierra@....com> To: akpm@...ux-foundation.org, Felix.Kuehling@....com, linux-mm@...ck.org, rcampbell@...dia.com, linux-ext4@...r.kernel.org, linux-xfs@...r.kernel.org Cc: amd-gfx@...ts.freedesktop.org, dri-devel@...ts.freedesktop.org, hch@....de, jgg@...dia.com, jglisse@...hat.com Subject: [PATCH v5 03/13] kernel: resource: lookup_resource as exported symbol The AMD architecture for the Frontier supercomputer will have device memory which can be coherently accessed by the CPU. The system BIOS advertises this memory as SPM (special purpose memory) in the UEFI system address map. The AMDGPU driver needs to be able to lookup this resource in order to claim it as MEMORY_DEVICE_GENERIC using devm_memremap_pages.
