drm/ttm: fix populate_and_map() functions once more

2017-11-29T19:42:35Z

This reverts "drm/ttm: Fix configuration error around populate_and_map() functions". This fix has gone into the wrong direction. Those helpers should be available even when neither CONFIG_INTEL_IOMMU nor CONFIG_SWIOTLB are set.

drm/ttm: Add helper functions to populate/map in one call (v2)

2017-08-29T19:27:52Z

These functions replace a section of common code found in radeon/amdgpu drivers (and possibly others) as part of the ttm_tt_*populate() callbacks. v2: squash in fix for sw iommu from Tom Signed-off-by: Tom St Denis Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/ttm: Add DMA map/unmap tracepoint (v3)

2017-08-29T19:27:50Z

Also exports two functions that vendor drivers can call to trace DMA mappings. This is meant to help translate IOMMU mappings of bus addresses back to physical pages. Used by the umr amdgpu debugger for instance. Signed-off-by: Tom St Denis Reviewed-by: Christian König Signed-off-by: Alex Deucher (v2): Use dev_name() to get PCI path instead. (v3): Use correct types for dma/phys addresses

drm/ttm: make ttm_mem_type_manager_func debug more useful

drm/ttm: Implement vm_operations_struct.access v2

2017-07-25T20:29:02Z

Allows gdb to access contents of user mode mapped BOs. System memory is handled by TTM using kmap. Other memory pools require a new driver callback in ttm_bo_driver. v2: * kmap only one page at a time * swap in BO if needed * make driver callback more generic to handle private memory pools * document callback return value * WARN_ON -> WARN_ON_ONCE Signed-off-by: Felix Kuehling Reviewed-by: Christian König Reviewed-by: Michel Dänzer Signed-off-by: Alex Deucher

drm/ttm: fix include notation and remove -Iinclude/drm flag

2017-05-16T15:17:16Z

For the C file, include instead of relative path from include/drm. For headers in include/drm/ttm, simplify the with "*.h". This allows us to remove the -Iinclude/drm compiler flag from drivers/gpu/drm/ttm/Makefile (and from other drivers' Makefiles).
