From 90489ce18c3a504c781c8cfcec013258c3459328 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 15 Aug 2019 09:27:01 +0200 Subject: [PATCH] drm/amdgpu: handle PCIe root ports with addressing limitations MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit amdgpu uses a need_dma32 flag to indicate to the drm core that some allocations need to be done using GFP_DMA32, but it only checks the device addressing capabilities to make that decision. Unfortunately PCIe root ports that have limited addressing exist as well. Use the dma_addressing_limited instead to also take those into account.
