      viafb: add X server compatibility mode · 2946294f
      由 Florian Tobias Schandinat 提交于 
      This patch adds a config option to be compatible with X servers like
OpenChrome. This is required as for example the X server does not
handle things like disabled IGAs/PLLs resulting in a potential
freeze on X startup. With this option disabled we can provide some
nice features like power management and not reinitializing the
hardware on every mode switch (taking long time, causing flickering).

      s3fb: add DDC support · 86c0f043
      由 Ondrej Zary 提交于 
      Add I2C support for the DDC bus and also default mode initialization by
reading monitor EDID to the s3fb driver.

Tested on Trio64V+ (2 cards), Trio64V2/DX, Virge (3 cards),
Virge/DX (3 cards), Virge/GX2, Trio3D/2X (4 cards), Trio3D.

Will probably not work on Trio32 - my 2 cards have DDC support in BIOS that
looks different from the other cards but the DDC pins on the VGA connector
are not connected.

      video: Add i.MX23/28 framebuffer driver · f0a523b5
      由 Sascha Hauer 提交于 
      changes since v2:

- use v3 and v4 for specifying the ip version instead of i.MX23/28.
  This is a better namespace when future versions are added.
- rename mach/fb.h to mach/mxsfb.h

changes since v1:
- Add a LCDC_ prefix to the register names.
- use set/clear registers where appropriate
- protect call to mxsfb_disable_controller() in mxsfb_remove()
  with a (host->enabled) as suggested by Lothar Wassmann

      kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT · 6a108a14
      由 David Rientjes 提交于 
      The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel.  A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

      video: Fix the HGA framebuffer driver · 529ed806
      由 Brent Cook 提交于 
      Resurrected some old hardware and fixed up the hgafb driver to work
again. Only tested with fbcon, since most fbdev-based software appears
to only support 12bpp and up. It does not appear that this driver has
worked for at least the entire 2.6.x series, perhaps since 2002.

Hercules graphics hardware uses packed pixels horizontally, but rows are
not linear. In other words, the pixels are not packed vertically. This
means that custom imageblit, fillrect and copyarea need to be written
specific to the hardware.

 * Removed the experimental acceleration option, since it is required
   for the hardware to work.
 * Fixed imageblit to work with fb_image's wider than 8 pixels.
 * Updated configuration text (HGA hardware is from 1984)

      video: add driver for PXA3xx 2D graphics accelerator · 364dbdf3
      由 Daniel Mack 提交于 
      This adds a driver for the the 2D graphics accelerator found on PXA3xx
processors. Only resource mapping, interrupt handling and a simple ioctl
handler is done by the kernel part, the rest of the logic is implemented
in DirectFB userspace.

Graphic applications greatly benefit for line drawing, blend, and
rectangle and triangle filling operations.

Benchmarks done on a PXA303 using the df_dok benchmarking tool follow,
where the value in square brackets show the CPU usage during that test.

Without accelerator (benchmarking 256x252 on 480x262 RGB16 (16bit)):

      viafb: make procfs entries optional

This patch adds a config option to enable procfs entries for direct
hardware access. This was the old behaviour but the option defaults
to no as this is really ugly and should not be needed if the driver
works correct (and if it doesn't, it needs to be fixed).
That stuff is really something that should
- not be needed at all (the driver should be capable of doing it)
- not be there (debugfs would be better for such things)
So add this option just for backwards compatiblity.

      viafb: add a driver for GPIO lines · 7e0de022

      This is a simple gpiolib driver giving access to the GPIO lines in the
VIA framebuffer system.  A simple mechanism exists for switching lines
between GPIO and I2C, but it's only compile-time for now.
