DRM: add mode setting support

2008-12-29T07:47:23+00:00

Add mode setting support to the DRM layer.

This is a fairly big chunk of work that allows DRM drivers to provide
full output control and configuration capabilities to userspace.  It was
motivated by several factors:
  - the fb layer's APIs aren't suited for anything but simple
    configurations
  - coordination between the fb layer, DRM layer, and various userspace
    drivers is poor to non-existent (radeonfb excepted)
  - user level mode setting drivers makes displaying panic & oops
    messages more difficult
  - suspend/resume of graphics state is possible in many more
    configurations with kernel level support

This commit just adds the core DRM part of the mode setting APIs.
Driver specific commits using these new structure and APIs will follow.

fbcon: Protect free_irq() by MACH_IS_ATARI check

2008-12-28T19:00:06+00:00

Add missing check for Atari in free_irq() call, which could cause problems on
multi-platform m68k kernels.

fbcon: remove broken mac vbl handler

2008-12-28T19:00:06+00:00

Remove the Mac VBL interrupt code as it doesn't work properly and
doesn't bring any benefit when fixed. Also remove unused
DEFAULT_CURSOR_BLINK_RATE macro and irqres variable.

fbcon: fix workqueue shutdown

2008-12-10T16:01:53+00:00

Add a call to cancel_work_sync() in fbcon_exit() to cancel any pending
work in the fbcon workqueue.

The current implementation of fbcon_exit() sets the fbcon workqueue
function info->queue.func to NULL, but does not assure that there is no
work pending when it does so.  On occasion, depending on system timing,
there will still be pending work in the queue when fbcon_exit() is
called.  This results in a null pointer deference when run_workqueue()
tries to call the queue's work function.

Fixes errors on shutdown similar to these:

  Console: switching to colour dummy device 80x25
  Unable to handle kernel paging request for data at address 0x00000000

fbdev: fix FB console blanking

2008-12-02T03:55:25+00:00

The commit aef7db4bd5a3b6068dfa05919a3d685199eed116 fixed the problem with
recursive locking in fb blanking code if blank is caused by user setting
the /sys/class/graphics/fb*/blank.  However this broke the fbcon timeout
blanking.

If you use a driver that defines ->fb_blank operation and at the same time
that driver relies on other driver (e.g.  backlight or lcd class) to blank
the screen, when the fbcon times out and tries to blank the fb, it will
call only fb driver blanker and won't notify the other driver.  Thus FB
output is disabled, but the screen isn't blanked.

Restore fbcon blanking and at the same time apply the proper fix for the
above problem: if fbcon_blank is called with FBINFO_FLAG_USEREVENT, we are
already called through notification from fb_blank, thus we don't have to
blank the fb again.

fbcon: don't inline updatescrollmode

2008-10-30T18:38:46+00:00

Updatescrollmode is marked inline, but it's big and is called only from
non-critical codepaths (fbcon_resize, fbcon_switch, fbcon_modechanged).
Dropping it saves almost 800 bytes of text size.
