drm/ttm: fix LRU handling in ttm_buffer_object_transfer

2018-12-21T13:15:15+00:00

[ Upstream commit d6e820fcd4cf08b11d291a1dd7bbd0636914647c ] We need to set the NO_EVICT flag on the ghost object or otherwise we are adding it to the LRU. When it is added to the LRU we can run into a race between destroying and evicting it again.

drm/ttm: clean up non-x86 definitions on ttm_tt

drm/ttm: Merge hugepage attr changes in ttm_dma_page_put. (v2)

2018-07-27T20:00:22+00:00

Every set_pages_array_wb call resulted in cross-core interrupts and TLB flushes. Merge more of them for less overhead. This reduces the time needed to free a 1.6 GiB GTT WC buffer as part of Vulkan CTS from ~2 sec to < 0.25 sec. (Allocation still takes more than 2 sec though) (v2): use set_pages_wb instead of set_memory_wb.

drm/ttm: Replace ttm_bo_unref() with ttm_bo_put()

2018-07-10T19:18:28+00:00

A call to ttm_bo_unref() clears the supplied pointer to NULL, while ttm_bo_put() does not. None of the converted call sites requires the pointer to become NULL, so the respective assign operations has been left out from the patch.

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

2018-07-10T19:18:15+00:00

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: use swap macro in ttm_bo_handle_move_mem

2018-07-10T19:18:08+00:00

Make use of the swap macro and remove unnecessary variable *tmp_mem*. This makes the code easier to read and maintain. Also, reduces the stack usage. This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R. Silva Reviewed-by: Christian König Signed-off-by: Alex Deucher
