After conversion, a number of cleanups can be applied. The fbdev conversion is in patch 1. As udl was the only remaining external user of unlink_framebuffer(), that function now becomes an internal interface of the fbdev code (Patches 2 + 3). The patchset has been tested by running the console, X11 and Weston on a DisplayLink adapter. v5: * initialize console after registering device v4: * go back to 24 bpp by default, 16 bpp for console * keep udl_gem_object_free_object(); required by damage handler 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 (3): drm/udl: Replace fbdev code with generic emulation 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 | 8 +- drivers/gpu/drm/udl/udl_drv.h | 6 - drivers/gpu/drm/udl/udl_fb.c | 282 ------------------------------ drivers/gpu/drm/udl/udl_main.c | 6 - drivers/gpu/drm/udl/udl_modeset.c | 1 - drivers/video/fbdev/core/fbmem.c | 3 +- include/drm/drm_fb_helper.h | 6 - include/linux/fb.h | 1 - 9 files changed, 9 insertions(+), 320 deletions(-) --- 2.23.0
