Subject: [PATCH 00/46] fbdev: Init fb_ops with helpers for I/O memory
Date: Wed, 27 Sep 2023 09:26:33 +0200 [thread overview]
Message-ID: <20230927074722.6197-1-tzimmermann@suse.de> (raw)
Initialize struct fb_ops for drivers for hardware with framebuffers
in I/O-memory ranges with the respective helper macros. Also select
the appropriate Kconfig dependencies.
The patchset is part of a larger effort to modularize the fbdev core
and make it more adaptable. Most of these drivers do not initialize
the fb_read, fb_write and fb_mmap callbacks in fb_ops. By leaving the
callback pointers to NULL, they rely on the fbdev core to invoke the
I/O-memory helpers by default. This default makes it impossible to
remove the I/O-memory helpers on systems that don't need them. Setting
the pointers explicitly will allow for the removal of the default. If
a callback in fb_ops is unset, the operation will then be unsupported.
Initializing struct fb_ops via helpers macros will also allow for a
fine-grained setup, depending on Kconfig options. For example, it
will be possible to leave out file I/O if FB_DEVICE has not been
set.
This patchset contains the majority of fbdev driver work. The updated
drivers now initialize fb_ops with __FB_DEFAULT_IOMEM_OPS_RDWR,
__FB_DEFAULT_IOMEM_OPS_DRAW and/or __FB_DEFAULT_IOMEM_OPS_MMAP if
possible. Some drivers now use FB_DEFAULT_IOMEM_OPS, which sets all
fields correctly. In Kconfig, each driver selects FB_IOMEM_FOPS to
get the helpers for I/O memory. Drivers that use _RDWR, _DRAW and
_MMAP unconditionally select FB_IOMEM_HELPERS, which selects the
correct modules automatically.
