drm: Add \|struct drm_gem_vram_object\| and helpers The type \|struct drm_gem_vram_object\| implements a GEM object for simple framebuffer devices with dedicated video memory. The BO is either located in VRAM or system memory. The implementation has been created from the respective code in ast, bochs and mgag200. These drivers copy their implementation from each other; except for the names of several data types. The helpers are currently build with TTM, but this is considered an implementation detail and may change in future updates. v5: * do WARN_ON_ONCE for pin-count mismatches * allocate only 2 entries in placements array v4: * cleanups from checkpatch.pl * removed several fixed-size types from interfaces * DRM_VRAM_HELPER now selects DRM_TTM * remove separate config option for GEM VRAM v2: * rename to \|struct drm_gem_vram_object\| * move drm_is_gem_ttm() to a later patch in the series * add drm_gem_vram_kmap_at() * return is_iomem from kmap functions * redefine TTM placement flags for public interface * documentation fixes Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Link: http://patchwork.freedesktop.org/patch/msgid/20190508082630.15116-2-tzimmermann@suse.de Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> 2019-05-08 08:26:11 +00:00			`// SPDX-License-Identifier: GPL-2.0-or-later`
