+Subject: [PATCH] drm/amdgpu: Fix VRAM BO swap issue
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+DRM buddy manager allocates the contiguous memory requests in
+a single block or multiple blocks. So for the ttm move operation
+(incase of low vram memory) we should consider all the blocks to
+compute the total memory size which compared with the struct
+ttm_resource num_pages in order to verify that the blocks are
+contiguous for the eviction process.
+
+v2: Added a Fixes tag
+v3: Rewrite the code to save a bit of calculations and
+    variables (Christian)
+
+Fixes: c9cad937c0c5 ("drm/amdgpu: add drm buddy support to amdgpu")
