drm/cma: include as needed

drm/gem: create drm_gem_dumb_destroy

2013-08-06T23:59:24Z

All the gem based kms drivers really want the same function to destroy a dumb framebuffer backing storage object. So give it to them and roll it out in all drivers. This still leaves the option open for kms drivers which don't use GEM for backing storage, but it does decently simplify matters for gem drivers.

drm/cma: remove GEM CMA specific dma_buf functionality

2013-07-05T05:44:54Z

We can use prime helpers instead. Signed-off-by: Joonyoung Shim Acked-by: Laurent Pinchart Signed-off-by: Dave Airlie

drm/cma: add low-level hook functions to use prime helpers

2013-07-05T05:44:49Z

Instead of using the dma_buf functionality for GEM CMA, we can use prime helpers if we can provide low-level hook functions for GEM CMA. Signed-off-by: Joonyoung Shim Acked-by: Laurent Pinchart Signed-off-by: Dave Airlie

drm/cma: add debugfs helpers

2013-02-17T22:55:42Z

Add helper to display fb's which can be used directly in drm_info_list: static struct drm_info_list foo_debugfs_list[] = { ... { "fb", drm_fb_cma_debugfs_show, 0 }, }; to display information about CMA fb objects, as well as a drm_gem_cma_describe() which can be used if the driver bothers to keep a list of CMA GEM objects.

DRM: Add DRM GEM CMA helper

2012-09-18T10:28:21Z

Many embedded drm devices do not have a IOMMU and no dedicated memory for graphics. These devices use CMA (Contiguous Memory Allocator) backed graphics memory. This patch provides helper functions to be able to share the code. The code technically does not depend on CMA as the backend allocator, the name has been chosen because CMA makes for a nice, short but still descriptive function prefix.
