fbdev/core: Rework fb init code

2023-06-27T07:58:51+00:00

Init the class "graphics" before the rest of fbdev. Later steps, such as the sysfs code, depend on the class. Also arrange the module's exit code in reverse order. Unexport the global variable fb_class, which is only shared internally within the fbdev core module.

fbdev/core: Move file-I/O code into separate file

Move fbdev's file-I/O code into a separate file and contain it in init and cleanup helpers.

fbdev/core: Move procfs code to separate file

2023-06-27T07:58:51+00:00

Move fbdev's procfs code into a separate file and contain it in init and cleanup helpers. For the cleanup, replace remove_proc_entry() with proc_remove(). It is equivalent in functionality, but looks more like an inverse of proc_create_seq(). v2: * document proc_remove() usage (Sam) * revert unrelated removal of for_each_registered_fb() Signed-off-by: Thomas Zimmermann Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20230613110953.24176-36-tzimmermann@suse.de

fbdev/core: Add fb_device_{create,destroy}()

2023-06-27T07:58:51+00:00

Move the logic to create and destroy fbdev devices into the new helpers fb_device_create() and fb_device_destroy(). There was a call to fb_cleanup_device() in do_unregister_framebuffer() that was too late. The device had already been removed at this point. Move the call into fb_device_destroy(). Declare the helpers in the new internal header file fb_internal.h, as they are only used within the fbdev core module.

fbdev/core: Pass Linux device to pm_vt_switch_*() functions

2023-06-27T07:58:50+00:00

Pass the Linux device to pm_vt_switch_*() instead of the virtual fbdev device. Prepares fbdev for making struct fb_info.dev optional. The type of device that is passed to the PM functions does not matter much. It is only a token within the internal list of known devices. The PM functions do not refer to any of the device's properties or its type. Signed-off-by: Thomas Zimmermann Cc: "Rafael J.

Replace include statements for with . Fixes the coding style: if a header is available in asm/ and linux/, it is preferable to include the header from linux/.

fbdev: Move I/O read and write code into helper functions

2023-05-08T13:28:34+00:00

Move the existing I/O read and write code for I/O memory into the new helpers fb_cfb_read() and fb_cfb_write(). Make them the default fp_ops. No functional changes. In the near term, the new functions will be useful to the DRM subsystem, which currently provides it's own implementation. It can then use the shared code. In the longer term, it might make sense to revise the I/O helper's default status and make them opt-in by the driver. Systems that don't use them would not contain the code any longer. v2: * add detailed commit message (Javier) * rename fb_cfb_() to fb_io_() (Geert) * add fixes that got lost while moving the code (Geert) Signed-off-by: Thomas Zimmermann Tested-by: Sui Jingfeng Reviewed-by: Javier Martinez Canillas Acked-by: Helge Deller Reviewed-by: Sam Ravnborg Link: https://patchwork.freedesktop.org/patch/msgid/20230428122452.4856-19-tzimmermann@suse.de
