The fields are writeable in struct fbcon_ops. Each case; unrotated, various rotated and tile-based drawing; uses a set of related calbacks. Updating these 'bitops' at runtime is spread throughout various helper functions. This series puts related callbacks into dedicated instances of the new type struct fbcon_bitops. Changing the callbacks at runtime then only requires to pick the correct instance. It further allows the various struct fbcon_bitops' to be declared 'static const', which makes them write-protected at runtime. v2: - rename struct fbcon_ops to struct fbcon_par - drop patch 6 Thomas Zimmermann (5): fbcon: Fix empty lines in fbcon.h fbcon: Rename struct fbcon_ops to struct fbcon_par fbcon: Set rotate_font callback with related callbacks fbcon: Move fbcon callbacks into struct fbcon_bitops fbcon: Streamline setting rotated/unrotated bitops drivers/video/fbdev/core/bitblit.c | 122 +++---- drivers/video/fbdev/core/fbcon.c | 459 ++++++++++++------------ drivers/video/fbdev/core/fbcon.h | 17 +- drivers/video/fbdev/core/fbcon_ccw.c | 151 ++++---- drivers/video/fbdev/core/fbcon_cw.c | 151 ++++---- drivers/video/fbdev/core/fbcon_rotate.c | 47 +-- drivers/video/fbdev/core/fbcon_rotate.h | 18 +- drivers/video/fbdev/core/fbcon_ud.c | 167 ++++----- drivers/video/fbdev/core/softcursor.c | 18 +- drivers/video/fbdev/core/tileblit.c | 32 +- 10 files changed, 604 insertions(+), 578 deletions(-) -- 2.51.0
