drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers

2021-02-23T07:54:22Z

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting, but currently located next to framebuffer helpers. Move it to GEM atomic helpers, rename it slightly and adopt the drivers. Same for the rsp simple-pipe helper. Compile-tested with x86-64, aarch64 and arm. The patch is fairly large, but there are no functional changes. v3: * remove out-comented line in drm_gem_framebuffer_helper.h (Maxime) v2: * rename to drm_gem_plane_helper_prepare_fb() (Daniel) * add tutorial-style documentation Signed-off-by: Thomas Zimmermann Acked-by: Maxime Ripard Link: https://patchwork.freedesktop.org/patch/msgid/20210222141756.7864-1-tzimmermann@suse.de

drm/core: Add drm_afbc_framebuffer and a corresponding helper

2020-03-18T10:22:05Z

The new struct contains afbc-specific data. The new function can be used by drivers which support afbc to complete the preparation of struct drm_afbc_framebuffer. It must be called after allocating the said struct and calling drm_gem_fb_init_with_funcs().

drm/core: Allow drivers allocate a subclass of struct drm_framebuffer

2020-03-18T10:21:32Z

Allow allocating a specialized version of struct drm_framebuffer by moving the actual fb allocation out of drm_gem_fb_create_with_funcs(); the respective functions names are adjusted to reflect that fact. Please note, though, that standard size checks are performed on buffers, so the drm_gem_fb_init_with_funcs() is useful for cases where those standard size checks are appropriate or at least don't conflict the checks to be performed in the specialized case. Thanks to this change the drivers can call drm_gem_fb_init_with_funcs() having allocated their special version of struct drm_framebuffer, exactly the way the new version of drm_gem_fb_create_with_funcs() does.

drm/fb: remove unused function: drm_gem_fbdev_fb_create()

2019-07-21T17:32:38Z

After migrating several drivers to the generic fbdev emulation there are no users left of drm_gem_fbdev_fb_create. Delete the function. Noticed that there was no callers while browsing around in the drm_fb* code. The code that referenced the function was removed by: commit 13aff184ed9f ("drm/qxl: remove dead qxl fbdev emulation code") The actual use was removed by: commit 26d4707d445d ("drm/qxl: use generic fbdev emulation") v2: - Updated changelog based on feedback from Noralf Signed-off-by: Sam Ravnborg Reviewed-by: Noralf Trønnes Cc: Gerd Hoffmann Cc: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20190721140610.GA20842@ravnborg.org

drm/gem-fb-helper: Use debug message on gem lookup failure

GEM lookup failure can easily be triggered by userspace so make it a debug message, not an error message. Also remove unnecessary inner parentheses and fix alphabetical struct declaration order.

drm: Add GEM backed framebuffer library

This library provides helpers for drivers that don't subclass drm_framebuffer and are backed by drm_gem_object. The code is taken from drm_fb_cma_helper.
