Antonino A. Daplas 22d832edca savagefb: VGA state save and restore
Allow the saving and restoration of VGA text mode.  The state is saved on the
first open and restored on the last close. Because of the VGA registers are
linearly mapped to the MMIO space, MMIO access is used which is not limited to
X86 platforms nor to the primary display device.

Antonino A. Daplas 70802c6037 fbdev: don't show logo if driver or fbcon are modular
It was always intended for the logo to be drawn only if both fbcon and the
driver that is mapped to it are both compiled statically.  Currently, if fbcon
is loaded prior to the driver, the logo is not shown.  Reverse the order, and
the code may attempt to draw the logo which is __initdata.  By accident, this
bug is rarely seen because this method of loading the modules is not common
and secondly, a code in fb_prepare_logo() that checks the height of the logo
(now a random value) rarely succeeds.

Fix by drawing the logo only if both fbcon and the driver are statically
compiled.

found in CRTC0's registers that panel size is 1920x1200 (Windows also agree
that 1920x1200 is primary monitor, and 1920x1080i secondary one).

When I applied attached patch then my monitor became as happy as it was

Jaya Kumar 60b59beafb fbdev: mm: Deferred IO support
This implements deferred IO support in fbdev.  Deferred IO is a way to delay
and repurpose IO.  This implementation is done using mm's page_mkwrite and
page_mkclean hooks in order to detect, delay and then rewrite IO.  This
functionality is used by hecubafb.

[adaplas]
This is useful for graphics hardware with no directly addressable/mappable
framebuffer. Implementing this will allow the "framebuffer" to be accesible
from user space via mmap().

apps may not.

Antonino A. Daplas 464bdd33e9 fbdev: ignore VESA modes if framebuffer is disabled
If the option vga=<VESA graphics mode> is added to the boot parameter, it will
activate graphics mode, but without any framebuffer support, the user is left
with an unusable display.

Change the behavior such that the user is instead prompted for another mode
(ala vga=ask).

NOTE: People can always use vbetool to set a graphics mode if this is really
desired, but the number of people doing this approaches zero.

Antonino A. Daplas 66fd14120e nvidiafb: bring back generic ddc reading
Make nvidiafb use fb_ddc_read().  This patch was submitted before but was
reverted due to problems in a non-x86 platform.  This includes a fix for that
where ddc reading is bypassed if there is no DDC bus (duh).

Orczykowski, Juergen 71c6efd993 intelfb: fix ring space calculation
If there is less than RING_MIN_FREE available in the ring buffer,
dinfo->ring_space is set to a big value forcing wait_ring to return.

Fix by making ring space = 0 if ring space < RING_MIN_FREE.

Antonino A. Daplas 33a9f640a2 fbdev: add Ultrasharp UXGA to broken monitor database
This particular monitor does not have a limits block and has only one set of
monitor timings.  Fix by adding a limits block to the EDID and extend the
horizontal sync frequency range to 30 kHz and 75 Khz.
