      G2D: Hardware acceleration for XCopyArea (initially 32bpp only) · ecfeb4aa
      Siarhei Siamashka authored 
      

Wrap CreateGC function to add a hook for CopyArea operation, which
can be accelerated using G2D for the buffers inside of the visible
part of the framebuffer. In the future we may try to also ensure
that DRI2 buffers are copied using G2D instead of CPU in the case
if we hit the fallback path and can't avoid this copy.

Benchmark using "x11perf -scroll500 -copywinwin500":

      Add support for hardware ARGB cursors up to 32x32 size · 06ae9b68
      Siarhei Siamashka authored 
      

Actually they are converted to 32x32 with 256 color palette. In the
case if we have more than 256 unique colors, the color components
of the pixels are reduced from 8-bit to 7-bit, then to 6-bit if
necessary and so on (until we reduce the number of unique colors
so that they can fit the palette). In the worst case we may
theoretically end up with just 2 bits per A, R, G and B channels,
but in practice 7 or 6 bits seem to be enough.

      Disable hardware layers when software ARGB cursor is used · 0ab0a9e8
      Siarhei Siamashka authored 
      

The modern desktops may use ARGB cursors. As the current
sunxi display controller support code can't handle this
type of cursor yet, the X server fallbacks to a software
cursor which is not visible under layers and ruining user
experience.

This patch adds empty implementations for "UseHWCursorARGB"
and "LoadCursorARGB" functions which just return error for
now (so that the X server still fallbacks to software cursor).
However we also introduce callback functions responsible for
notifying the DRI2 code about enabling/disabling the use of
hardware cursor. So that now hardware overlays are disabled
when switching to software cursor and re-enabled again when
switching back to hardware cursor.

      Support for sunxi hardware cursor · 64d51c0f
      Siarhei Siamashka authored 
      Hardware cursor is necessary because it is also visible on
top of sunxi disp layers, while software cursor is not.

FIXME: there is one minor problem with negative cursor
positions. The hardware does not support them, so such
positions are just set to 0 for now. In the future this
can be solved better by changing the cursor picture and
showing only the parts which are visible on screen.

      Added supplementary wrapper functions for sunxi display controller ioctls · bf7c7a6c
      Siarhei Siamashka authored 
      Note: the header file "sunxi_disp_ioctl.h" is GPL licensed. So until
it is gets a MIT/X11 replacement, the DDX driver is GPL licensed as
a whole. The individual source files still have their own license.
Also in order to avoid any possible confusion, the MIT/X11 license
header from COPYING has been added to "fbdev.c" and "fbdev_priv.h".

      Rename "fbdev" -> "sunxifb" and update man page · 703aea28
      Siarhei Siamashka authored 
      As there is no way for the hardware specific bits to be accepted
in xf86-video-fbdev, we need a new driver with its own name.
