Eric Anholt c7ac485a59 Remove the default case from fbcompose.c switches which should cover all cases. 
Instead, stick the NULL return default case afterwards, so that the compiler can
warn us when we've got unimplemented cases.  Removes some unimplemented and
unused 8bpp, depth 4 picture format names.

Ian Romanick 383c2e1e9e Include fbmmx.h in fb/fbwindow.c when USE_MMX is defined. Fixes build 
problem on x86-64 resulting from fbHaveMMX being a macro instead of a
    function on that platform.

Søren Sandmann Pedersen 5449634e3c Wed Mar 22 16:28:46 2006 Søren Sandmann <sandmann@redhat.com> 
Use inline assembly for copy area, since gcc doesn't generate movq
    instructions.

Søren Sandmann Pedersen 5b3084c64f Wed Mar 22 16:05:09 2006 Søren Sandmann <sandmann@redhat.com>

    instructions.

Benjamin Herrenschmidt 049dca0f43 Remove useless line of code that contained a bug and triggered a gcc 
warning. This variable will be overriden before being used anyway.

Alan Coopersmith a2a5254675 Add <string.h>, <stdlib.h>, and <stdio.h> to clear undefined function 
warnings after the removal of libcwrapper headers.
 2006-02-11 19:16:51 +00:00
Eric Anholt c3d1403672 Remove libcwrapper usage from xorg server modules. The libcwrapper is only 
of (marginal) use in the drivers, and that usage remains.
 2006-02-10 22:00:30 +00:00
Adam Jackson 1c3f8727b2 More kdrive merge, fast path fbBlt to use memcpy() when possible. Good for 
-5% to 60% speedup on XGetImage, and 0% to 10% speedup on copies within
    host memory. Based on work by Jaymz Julian.

Dave Airlie 8ccf4f2b8f This is a fix from David Reveman from the xserver tree, Make fbPadPixmap 
work with negative stride

Kevin E Martin 89c661d61f Only use fbCopyAreammx if planemask is FB_ALLONES (fixes XTS5 XCopyArea 
tests 22 and 23).
 2005-11-04 21:37:32 +00:00
Kristian Høgsberg dc6ac8e46f Add DGA configure option and add various files that we should be dist'ing. 
Simplify xf86DefModeSet.c rule a bit.
 2005-10-05 21:38:40 +00:00
Eric Anholt b2e451b93c Correct the test for whether projective transform is necessary. Also, use 
"affine" to describe the variable (universally) on suggestion from
    vektor. Corrects a rendercheck failure.
 2005-10-04 03:44:14 +00:00
Adam Jackson d51962378e Bug #3781: Only use fbCopyAreammx when alu == GXcopy. Originally Gentoo bug 
#96053, patch by bartron@gmx.net.

Eric Anholt 84141fc299 Merge r1.36 of fbcompose.c from xserver CVS: Special case projective 
transforms so we can avoid doing the expensive
64-bit math. Unroll the bilinear interpolation loops for an extra boost. I
    tested this with the up/downscaling cairo-benchmarks with Xvfb and saw
    a 12% +/- 4% decrease in time taken to run them.
 2005-10-03 11:43:55 +00:00
Eric Anholt c024262eae Merge r1.2 of fbedge.c from xserver CVS: Optimize spans where the same 
value is being added to multiple pixels. This improves the speed of
    rendering wide trapezoids. I tested this with a small set of xlibs
    cairo-benchmarks with Xvfb and saw a 4% decrease in time taken to run
    them.

Eric Anholt ecaa46380e Bugzilla #4616: 
- Merge various fb/ bits of COMPOSITE support from xserver, which weren't
    necessary before due to cw hiding the issues. Fixes offset calculations
    for a number of operations, and may pull some fixes that cairo has
    wanted for XAA as well.
- Add a new call, miDisableCompositeWrapper(), which a DDX can call to keep
    cw from getting initialized from the damage code. While it would be
    cleaner to have each DDX initialize it if it needs it, we don't have
    control over all of them (e.g. nvidia).
- Use the miDisableCompositeWrapper() to keep cw from getting set up for
    screens using EXA, because EXA is already aware of composite. Avoiding
    cw improved performance 0-35% on operations tested by ajax in x11perf.

    modified at points where we access external variables. (Bug 4269).

Daniel Stone c3d6799cee Bug #594: CAN-2005-2495: Fix exploitable integer overflow in pixmap 
creation, where we could create a far smaller pixmap than we thought,
    allowing changes to arbitrary chunks of memory. (Søren Sandmann
    Pedersen)

Søren Sandmann Pedersen bed3235d22 Thu Aug 18 17:27:09 2005 Søren Sandmann <sandmann@redhat.com> 
Move fbmmx to a convenience library since the mmx flags may be harmful when
    applied to non-mmx code.
