Subject: [PATCH v2 00/19] arch: Consolidate <asm/fb.h>
Date: Thu, 6 Apr 2023 16:30:00 +0200 [thread overview]
Message-ID: <20230406143019.6709-1-tzimmermann@suse.de> (raw)
Various architectures provide <arm/fb.h> with helpers for fbdev
framebuffer devices. Share the contained code where possible. There
is already <asm-generic/fb.h>, which implements generic (as in
'empty') functions of the fbdev helpers. The header was added in
commit aafe4dbed0bf ("asm-generic: add generic versions of common
headers"), but never used.
Each per-architecture header file declares and/or implements fbdev
helpers and defines a preprocessor token for each. The generic
header then provides the remaining helpers. It works like the I/O
helpers in <asm/io.h>.
For PARISC, the architecture helpers are mixed up with helpers
for the system's STI graphics firmware. We first move the STI code
to appropriate locations under video/ and then move the architecture
helper under arch/parisc.
For Sparc, there's an additional patch that moves the implementation
from the header into a source file. This allows to avoid some include
statements in the header file.
Built on arm, arm64, m68k, mips, parisc, powerpc, sparc and x86.
v2:
* make writecombine the default mapping mode (Arnd)
* rework fb_pgprotect() on m68k
