From 66257db7a5276d7f1aff8850388a0eb675ffa2e1 Mon Sep 17 00:00:00 2001 From: Nicolai Hähnle Date: Thu, 15 Dec 2016 17:23:49 +0100 Subject: drm/ttm: add evict parameter to ttm_bo_driver::move_notify MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Ensure that the driver can listen to evictions even when they don't take the path through ttm_bo_driver::move. This is crucial for amdgpu, which relies on an eviction counter to skip re-binding page tables when possible.
