drm: gem_cma_helper.c: Allow importing of contiguous scatterlists with nents > 1

2017-11-15T17:14:46Z

drm_gem_cma_prime_import_sg_table() will fail if the number of entries in the sg_table > 1. However, you can have a device that uses an IOMMU engine and can map a discontiguous buffer with multiple entries that have consecutive sg_dma_addresses, effectively making it contiguous. Allow for that scenario by testing the entries in the sg_table for contiguous coverage.

drm/gem-cma-helper: Change the level of the allocation failure message

2017-10-16T13:19:57Z

drm_gem_cma_create() prints an error message when dma_alloc_wc() fails to allocate the amount of memory we requested. This can lead to annoying error messages when CMA is only one possible source of memory for the BO allocation. Turn this error message into a debug one.

drm: Create DEFINE_DRM_GEM_CMA_FOPS and roll it out to drivers

2017-03-14T13:38:34Z

Less code ftw. This converts all drivers except the tinydrm helper module. That one needs more work, since it gets the THIS_MODULE reference from tinydrm.ko instead of the actual driver module like it should. Probably needs a similar trick like I used here with generating the entire struct with a macro.
