[PATCH v3 00/19] arch: Consolidate <asm/fb.h>

[Thomas Zimmermann]

Various architectures provide <asm/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.

v3:
	* use default fb_pgprotect() on arc, parisc, sparc64 (Arnd)
	* fix includes in generic fb.h
v2:
	* make writecombine the default mapping mode (Arnd)
	* rework fb_pgprotect() on m68k

[PATCH v3 00/19] arch: Consolidate <asm/fb.h>

[Thomas Zimmermann]

Various architectures provide <asm/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.

v3:
	* use default fb_pgprotect() on arc, parisc, sparc64 (Arnd)
	* fix includes in generic fb.h
v2:
	* make writecombine the default mapping mode (Arnd)
	* rework fb_pgprotect() on m68k

[PATCH v3 01/19] fbdev: Prepare generic architecture helpers

[Thomas Zimmermann]

Generic implementations of fb_pgprotect() and fb_is_primary_device()
have been in the source code for a long time. Prepare the header file
to make use of them.

Improve the code by using an inline function for fb_pgprotect()
and by removing include statements. The default mode set by
fb_pgprotect() is now writecombine, which is what most platforms
want.

Symbols are protected by preprocessor guards. Architectures that
provide a symbol need to define a preprocessor token of the same
name and value. Otherwise the header file will provide a generic
implementation. This pattern has been taken from <asm/io.h>.

v3:
	* include the correct header files
v2:
	*  use writecombine mappings by default (Arnd)

[PATCH v3 02/19] arch/arc: Implement <asm/fb.h> with generic helpers

[Thomas Zimmermann]

Replace the architecture's fbdev helpers with the generic ones from
<asm-generic/fb.h>. On arc, pgprot_writecombine() and pgprot_noncached()
are the same; hence no functional changes.

v3:
	* use default implementation for fb_pgprotect() (Arnd)

[PATCH v3 07/19] arch/m68k: Merge variants of fb_pgprotect() into single function

[Thomas Zimmermann]

Merge all variants of fb_pgprotect() into a single function body.
There are two different cases for MMU systems. For non-MMU systems,
the function body will be empty. No functional changes, but this
will help with the switch to <asm-generic/fb.h>.

[PATCH v3 07/19] arch/m68k: Merge variants of fb_pgprotect() into single function

[Thomas Zimmermann]

Merge all variants of fb_pgprotect() into a single function body.
There are two different cases for MMU systems. For non-MMU systems,
the function body will be empty. No functional changes, but this
will help with the switch to <asm-generic/fb.h>.

[PATCH v3 11/19] video: Move HP PARISC STI core code to shared location

[Thomas Zimmermann]

STI core files have been located in console and fbdev code. Move
the source code and header to the directories for video helpers.
Also update the config and build rules such that the code depends
on the config symbol CONFIG_STI_CORE, which STI console and STI
framebuffer select automatically.

Cleans up the console makefile and prepares PARISC to implement
fb_is_primary_device() within the arch/ directory. No functional
changes.

[PATCH v3 11/19] video: Move HP PARISC STI core code to shared location

[Thomas Zimmermann]

STI core files have been located in console and fbdev code. Move
the source code and header to the directories for video helpers.
Also update the config and build rules such that the code depends
on the config symbol CONFIG_STI_CORE, which STI console and STI
framebuffer select automatically.

Cleans up the console makefile and prepares PARISC to implement
fb_is_primary_device() within the arch/ directory. No functional
changes.

[PATCH v3 14/19] arch/parisc: Implement <asm/fb.h> with generic helpers

[Thomas Zimmermann]

Replace the architecture's fbdev helpers with the generic ones
from <asm-generic/fb.h>. On PARISC, pgprot_writecombine() and
pgprot_noncached() are the same; hence no functional changes.

v3:
	* use default implementation for fb_pgprotect() (Arnd)

Looking at the macro in asm-generic/fb.h, fb_pgprotect() is being replaced with

Patch 01 of this patchset changes the generic fb_pgprotect() to set 
pgprot_writecombine(). So on SH, there should be no change at all.

[PATCH v3 17/19] arch/sparc: Implement fb_is_primary_device() in source file

[Thomas Zimmermann]

Other architectures implment fb_is_primary_device() in a source
file. Do the same on sparc. No functional changes, but allows to
remove several include statement from <asm/fb.h>.

v2:
	* don't include <asm/prom.h> in header file

This patch results (or appears to result) in the following build error
when trying to build sparc64:allmodconfig.

Error log:

Bisect log attached. Note that I suspect that there are several problems,
but that is difficult to determine since this patch can not easily
be reverted.

These all look like old bugs that would be trivially fixed if
anyone cared about sparc.

> ERROR: modpost: missing MODULE_LICENSE() in arch/sparc/video/fbdev.o

I checked that there are no callers of fb_is_primary_device()
in built-in code when CONFIG_FB is =m, so adding the MODULE_LICENSE()
and MODULE_DESCRIPTION() tags to the file is the correct fix.

These all look like old bugs that would be trivially fixed if
anyone cared about sparc.

I checked that there are no callers of fb_is_primary_device()
in built-in code when CONFIG_FB is =m, so adding the MODULE_LICENSE()
and MODULE_DESCRIPTION() tags to the file is the correct fix.

Odd argument, given that this _is_ a sparc patch. Those may be old
bugs, but at least in 6.4-rc7 sparc64:allmodconfig does at least compile.

Sure, I can stop build testing it if that is where things are going.

The first three are non-fatal warnings even with CONFIG_WERROR=y, I'm
sure they have been there for years. I don't immediately see what
caused the __xchg_called_with_bad_pointer error, but it does not
look related to the fbdev patch. I would guess that this is a second
regression that happened to come in at the same time.

> Sure, I can stop build testing it if that is where things are going.

I think we clearly want to fix the fbdev regression you found, and
maybe bisect the atomic64_test as well to see if that was caused by
a recent patch to get it into a working state again.

Regarding whether to continue build testing: if every kernel build
warns about a missing syscall for almost four years (clone3 was
added in 5.3 and requires a minimal review to hook it up to asm
code), it shows that the architecture is seriously neglected
already.

The first three are non-fatal warnings even with CONFIG_WERROR=y, I'm
sure they have been there for years. I don't immediately see what
caused the __xchg_called_with_bad_pointer error, but it does not
look related to the fbdev patch. I would guess that this is a second
regression that happened to come in at the same time.

I think we clearly want to fix the fbdev regression you found, and
maybe bisect the atomic64_test as well to see if that was caused by
a recent patch to get it into a working state again.

Regarding whether to continue build testing: if every kernel build
warns about a missing syscall for almost four years (clone3 was
added in 5.3 and requires a minimal review to hook it up to asm
code), it shows that the architecture is seriously neglected
already.

[PATCH v3 18/19] arch/sparc: Implement <asm/fb.h> with generic helpers

[Thomas Zimmermann]

Replace sparc64's fb_pgprotect() with the generic one
from <asm-generic/fb.h>. On sparc, pgprot_writecombine() and
pgprot_noncached() are the same; hence no functional changes

v3:
	* use default implementation for fb_pgprotect() on
	  sparc64 (Arnd)
v2:
	* restore the original fb_pgprotect()

[PATCH v3 19/19] arch/x86: Implement <asm/fb.h> with generic helpers

[Thomas Zimmermann]

Include <asm-generic/fb.h> and set the required preprocessor tokens
correctly. x86 now implements its own set of fb helpers, but still
follows the overall pattern of the other <asm/fb.h> files.

Thanks a lot. I know that Helge wants to test the PARISC changes, so 
I'll keep this series pending for a bit longer. I'd like to merge the 
patches through the DRM tree, if no one objects.
