This patch moves all non-x86 abstraction to the ttm_set_memory header. It is to make function calling more clearly. (v2): add ttm_ prefix. Suggested-by: Christian König Signed-off-by: Huang Rui Reviewed-by: Bas Nieuwenhuizen Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/ttm: Introduce ttm_bo_get() and ttm_bo_put() for ref counting

2018-07-10T19:18:15Z

The TTM buffer-object interface provides ttm_bo_reference() and ttm_bo_unref() for managing reference counts. Replacing them with ttm_bo_get() and ttm_bo_put() aligns the API with conventions used throughout the Linux kernel. The implementation of ttm_bo_unref() clears the supplied pointer to NULL. This leads to workarounds where the caller saves the pointer's value before de-referencing the BO. ttm_bo_put() does not clear the supplied pointer.

drm/ttm: check if free mem space is under the lower limit

2018-02-27T04:09:46Z

the free mem space and the lower limit both include two parts: system memory and swap space. For the OOM triggered by TTM, that is the case as below: first swap space is full of swapped out pages and soon system memory also is filled up with ttm pages. and then any memory allocation request will run into OOM. to cover two cases: a. if no swap disk at all or free swap space is under swap mem limit but available system mem is bigger than sys mem limit, allow TTM allocation; b. if the available system mem is less than sys mem limit but free swap space is bigger than swap mem limit, allow TTM allocation. v2: merge two memory limit(swap and system) into one v3: keep original behavior except ttm_opt_ctx->flags with TTM_OPT_FLAG_FORCE_ALLOC v4: always set force_alloc as tx->flags & TTM_OPT_FLAG_FORCE_ALLOC v5: add an attribute for lower_mem_limit v6: set lower_mem_limit as 0 to keep original behavior Signed-off-by: Roger He Reviewed-by: Christian König Signed-off-by: Alex Deucher
