[PATCH v2 0/8] drm/tinydrm: Use vmalloc BO

This patchset adds a library for vmalloc buffer objects and makes use of it in tinydrm. The reason I want to move away from the cma helper, is that it restricts which drivers to PRIME import from, since cma requires the buffer to be physically continuous. Initially I looked at udl and decided to

[PATCH v2 2/8] drm: Add drm_device->fbdev pointer

[PATCH v2 7/8] drm/tinydrm: Use drm_vmalloc_bo

Use the vmalloc BO helper instead of the cma helper to be able to PRIME import from more drivers. The cma helper can only import physically continuous buffers, but tinydrm only requires the buffer to be virtually continuous. This switch also makes it possible to use the drm_fb_helper_lastclose()
