[PATCH] fbdev: include backlight.h only when KERNEL is defined

2006-08-14T19:54:29+00:00

linux/backlight.h pulls in header files (eg.  ioport.h) that break
compilation of userspace programs.  To solve the problem, only include
backlight.h in fb.h if compiling kernel stuff.

[PATCH] fbdev: statically link the framebuffer notification functions

2006-07-31T20:28:44+00:00

The backlight and lcd subsystems can be notified by the framebuffer layer
of blanking events.  However, these subsystems, as a whole, can function
independently from the framebuffer layer.  But in order to enable to the
lcd and backlight subsystems, the framebuffer has to be compiled also,
effectively sucking in a huge amount of unneeded code.

To prevent dependency problems, separate out the framebuffer notification
mechanism from the framebuffer layer and permanently link it to the kernel.

[PATCH] vt: Remove VT-specific declarations and definitions from tty.h

2006-07-10T20:24:16+00:00

MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a
function of the VT layer than the TTY one.  Moving these to vt.h and vt_kern.h
allows all of the framebuffer and VT console drivers to remove their
dependency on tty.h.

[PATCH] VT binding: Update fbcon to support binding

2006-06-26T16:58:33+00:00

The control for binding/unbinding is moved from fbcon to the console layer.
Thus the fbcon sysfs attributes, attach and detach, are also gone.

    1. Add a notifier event that tells fbcon if a framebuffer driver has been
       unregistered.  If no registered driver remains, fbcon will unregister
       itself from the console layer.

    2. Replaced calls to give_up_console() with unregister_con_driver().

    3. Still use take_over_console() instead of register_con_driver() to
       maintain compatibility

    4. Respect the parameter first_fb_vc and last_fb_vc instead of using 0 and
       MAX_NR_CONSOLES - 1. These parameters are settable by the user.

    5. When fbcon is completely unbound from the console layer, fbcon will
       also release (iow, decrement module reference counts to zero) all fbdev
       drivers. In other words, a bind or unbind request from the console layer
       will propagate down to the framebuffer drivers.

    6. If fbcon is not bound to the console, it will ignore all notifier
       events (except driver registration and unregistration) and all sysfs
       requests.

[PATCH] Detaching fbcon: sdd sysfs class device entry for fbcon

2006-06-26T16:58:32+00:00

In order for this feature to work, an interface will be needed.  The most
appropriate is sysfs.  However, the framebuffer console has no sysfs entry
yet.  This will create a sysfs class device entry for fbcon under
/sys/class/graphics.

Add a class_device entry 'fbcon' under class 'graphics'.  Console-specific
attributes which where previously under class/graphics/fb[x] are moved to
class/graphics/fbcon.  These attributes, 'con_rotate' and 'con_rotate_all',
are also renamed to 'rotate' and 'rotate_all' respectively.

[PATCH] Rewritten backlight infrastructure for portable Apple computers

2006-06-25T17:00:59+00:00

This patch contains a total rewrite of the backlight infrastructure for
portable Apple computers.  Backward compatibility is retained.  A sysfs
interface allows userland to control the brightness with more steps than
before.  Userland is allowed to upload a brightness curve for different
monitors, similar to Mac OS X.

[PATCH] fbcon: Fix big-endian bogosity in slow_imageblit()

2006-03-31T20:19:00+00:00

The monochrome->color expansion routine that handles bitmaps which have
(widths % 8) != 0 (slow_imageblit) produces corrupt characters in big-endian.
This is caused by a bogus bit test in slow_imageblit().

Fix.

This patch may deserve to go to the stable tree.  The code has already been
well tested in little-endian machines.  It's only in big-endian where there is
uncertainty and Herbert confirmed that this is the correct way to go.

It should not introduce regressions.
