From: Nicolai Hähnle Date: Thu, 15 Dec 2016 16:23:49 +0000 (+0100) Subject: drm/ttm: add evict parameter to ttm_bo_driver::move_notify X-Git-Tag: v4.14-rc1~1422^2~31^2~61 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=66257db7a5276d7f1aff8850388a0eb675ffa2e1;p=platform%2Fkernel%2Flinux-rpi3.git drm/ttm: add evict parameter to ttm_bo_driver::move_notify 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.
