After conversion, a number of cleanups can be applied. Patch 1 prepares the prefered defaults. 32 bpp work well with driver, console and X11. The fbdev conversion is in patch 2. The original fbdev code in udl mapped the framebuffer's GEM object memory unconditionally, and unmapped the memory in the object's free() function. The respective code in free() can now be removed (Patch 3). And as udl was the only remaining external user of unlink_framebuffer(), that function now becomes an internal interface of the fbdev code (Patches 4 + 5). The patchset has been tested by running the console, X11 and Weston on a DisplayLink adapter. v3: * use 32 bpp by default * use defaults for several callback functions * remove all fb module parameters * remove udl_fbdev_init() v2: * converted udl to SHMEM and recreated fbdev patchset on top Thomas Zimmermann (5): drm/udl: Set default color depth to 32 bpp drm/udl: Replace fbdev code with generic emulation drm/udl: Remove udl implementation of GEM's free_object() drm/fb-helper: Remove drm_fb_helper_unlink_fbi() fbdev: Unexport unlink_framebuffer() drivers/gpu/drm/drm_fb_helper.c | 16 +- drivers/gpu/drm/udl/udl_drv.c | 1 - drivers/gpu/drm/udl/udl_drv.h | 6 - drivers/gpu/drm/udl/udl_fb.c | 282 ------------------------------ drivers/gpu/drm/udl/udl_gem.c | 18 +- drivers/gpu/drm/udl/udl_main.c | 5 +- drivers/gpu/drm/udl/udl_modeset.c | 3 +- drivers/video/fbdev/core/fbmem.c | 3 +- include/drm/drm_fb_helper.h | 6 - include/linux/fb.h | 1 - 10 files changed, 6 insertions(+), 335 deletions(-) --- 2.23.0
