Subject: [PATCH 0/8] fbdev: Use helpers for deferred I/O
Date: Mon, 28 Aug 2023 15:14:16 +0200	[thread overview]
Message-ID: <20230828132131.29295-1-tzimmermann@suse.de> (raw)

Here's another patchset for deferred-I/O helpers. Update a number
of fbdev drivers with deferred I/O to use fbdev's helper macros and
Kconfig tokens.

Generating and initializing via helpers macros will later 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.

Each driver in special in its own way. The smscufx and udlfb drivers
support file I/O without damage updates. (That probably doesn't work
correctly.) So they provide their own mmap code. The hyperv_fb driver
sometimes operates on memory in I/O address spaces and fails to do
damage handling correctly for write operations. The picolcd and fbtft
drivers are outside of fbdev.

  fbdev/smscufx: Use fb_ops helpers for deferred I/O
