Driver for the Silicon Motion SM501 multifunction device framebuffer
subsystem.
This driver supports both the CRT and LCD panel heads, with some simple
acceleration for the cursor plotting and support for screen panning. There
is no current support for bitblt/drawing engines, which should be added at
a later date.
This has been tested on a number of configurations, including PCI and
generic-bus, on PPC, ARM and SH4

fb_info->bl_mutex is badly thought out and the backlight class doesn't
need it if the framebuffer/backlight register/unregister order is
consistent, particularly after the backlight locking fixes.
Fix the drivers to use the order:
backlight_device_register()
register_framebuffer()
unregister_framebuffer()
backlight_device_unregister()
and turn bl_mutex into a lock for the bl_curve data only.

The backlight core listens for blanking events and triggers a

Remove uneeded update_status call from chipsfb.c since the
backlight core now receives software blanking notifications
too.
Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
|

The backlight class wants notification whenever the console is blanked
but doesn't get this when hardware blanking fails and software blanking
is used. Changing FB_EVENT_BLANK to report both would be a behaviour
change which could confuse the console layer so add a new event for
software blanking and have the backlight class listen for both.

Convert internal semaphore to a mutex
Signed-off-by: Richard Purdie <rpurdie@rpsys.net>
|
|
backlight_device->sem has a very specific use as documented in the
header file. The external users of this are using it for a different
reason, to serialise access to the update_status() method.
backlight users were supposed to implement their own internal
serialisation of update_status() if needed but everyone is doing
things differently and incorrectly. Therefore add a global mutex to
take care of serialisation for everyone, once and for all.
Locking for get_brightness remains optional since most users don't
need it.
Also update the lcd class in a similar way.

After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there. Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm. I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).

Add the PS3 Virtual Frame Buffer Driver.

fb_videomode_to_var(): reset the virtual screen parameters when converting
from an fb_videomode to an fb_var_screeninfo.
Without this the old virtual screen parameters are kept. Hence you cannot
switch to a video mode with a lower resolution on frame buffer devices that
don't support virtual screens and panning, as values are not supposed to be
rounded down when they don't fit.
I also reordered the assignments to match the order of the individual members.

- has been marked as BROKEN for more than two years and
- is still marked as BROKEN.
Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.
But if anyone wants to ever revive this driver, the code is still
