[PATCH] vesafb: Drop blank hook

2006-01-10T16:01:42+00:00

From: Bugzilla Bug 5351

"After resuming from S3 (suspended while in X), the LCD panel stays black .
 However, the laptop is up again, and I can SSH into it from another
machine.

I can get the panel working again, when I first direct video output to the
CRT output of the laptop, and then back to LCD (done by repeatedly hitting
Fn+F5 buttons on the Toshiba, which directs output to either LCD, CRT or
TV) None of this ever happened with older kernels."

This bug is due to the recently added vesafb_blank() method in vesafb.  It
works with CRT displays, but has a high incidence of problems in laptop
users.  Since CRT users don't really get that much benefit from hardware
blanking, drop support for this.

[DRIVER MODEL] Convert platform drivers to use struct platform_driver

2005-11-09T22:32:44+00:00

This allows us to eliminate the casts in the drivers, and eventually
remove the use of the device_driver function pointer methods for
platform device drivers.

[PATCH] vesafb: Disable mtrr as the default

2005-11-07T15:53:52+00:00

vesafb occassionally gets the size wrong when setting the mtrr.  When X or DRI
attempts to set the mtrr, it will fail due to range overlap significantly
affecting their performance.  Disable mtrr and let the user explicitly enable
it with the mtrr:n option.

[PATCH] vesafb: Fix color palette handling

2005-11-07T15:53:51+00:00

Fix out-of-bounds bug.  The pseudopalette has room only for 16 entries, thus,
write only the first 16 entries to the pseudopalette.

[PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbcon

2005-11-07T15:53:50+00:00

According to Jon Smirl, filling in the field fb_cursor with soft_cursor for
drivers that do not support hardware cursors is redundant.  The soft_cursor
function is usable by all drivers because it is just a wrapper around
fb_imageblit.  And because soft_cursor is an fbcon-specific hook, the file is
moved to the console directory.

Thus, drivers that do not support hardware cursors can leave the fb_cursor
field blank.  For drivers that do, they can fill up this field with their own
version.

The end result is a smaller code size.  And if the framebuffer console is not
loaded, module/kernel size is also reduced because the soft_cursor module will
also not be loaded.

[PATCH] vesafb: Fix display corruption on display blank

2005-10-18T15:43:29+00:00

Reported by: Bob Tracy 

 "...I've got a Toshiba notebook (730XCDT -- Pentium 150MMX) for which
  I'm using the Vesa FB driver.  When the machine has been idle for some
  time and the driver attempts to powerdown the display, rather than the
  display going blank, it goes gray with several strange lines.  When I
  hit the "shift" key or other-wise wake up the display, the old video
  state is not fully restored..."

vesafb recently added a blank method which has only 2 states, powerup and
powerdown.  The powerdown state is used for all blanking levels, but in his
case, powerdown does not work correctly for higher levels of display
powersaving. Thus, for intermediate power levels, use software blanking,
and use only hardware blanking for an explicit powerdown.
