eglplatform.h pulls in Xlib.h on X11 platforms. Likewise, the egl glx
driver and egl programs needs to link to libX11. Make sure we use the
locations the user told us about.

The variable X_LIBS from AC_PATH_XTRA contains only the -L searchdir
parameter and not the -lX11 to link to Xlib. Use X11 prefixed build vars
for linking with Xlib to avoid the conflict.

This can break on systems that don't have a system X installation.

When points or lines are decomposed into triangles, we need to be sure
to disable polygon culling, stippling, "un-filled" modes, etc.
This patch sets the rasterization state to disable those things prior to
drawing points/lines with triangles, then restores the previous state
afterward.
The new piglit point-no-line-cull test checks this problem & solution.
|
|
This can be triggered by running the cairo tests using the gl backend
and softpipe.

Need to check pipe_blend_state::independent_blend_enable to determine
which render target/index to use when checking blend enable and colormask
state.
This is part of the fix for piglit/fbo-drawbuffers

This fixes the "no rule to make target -lm" error on darwin, reported by
Jeremy Huddleston.

This was missed in commit f7cbaae13d67c55abe81ac230de37f564365099f.

We had fast paths for PIPE_FUNC_LESS and LEQUAL before. To satisfy
OpenGL invariance rules, all depth compare modes should produce the
same fragment Z values.
Fixes progs/demos/singlebuffer.c

This is a back-port of commit ef2664da6c4db1b52ef351641e3ee949b87f9c7b
from master.
|
|
Fixing RGBA 4ub vertex colors.
|
|
With this feature, we get OpenGL version 2.0 and the progs/glsl/
demos run as-is.
|
|
This fixes a regression from commit a84575cdc0c8193b2c7858734e2ec6b1ec4511b2
which changed the depth/stencil format we were trying to use.
|
|
|
|
Allows compiz to work in depth 16.
The DRI2 getBuffersWithFormat hook is only required for 16/32 bit depth
buffers, for colour buffers the only requirement is that the format matches
the drawable depth, which we can't check here.

Could result in use of freed memory and consequently random crashes, e.g. on
screen resize.

Before, we only cleared the flags for the active tiles (the ones inside
the framebuffer bound). The problem is if we later bound a different,
larger surface to the tile cache we'd have some stale clear-flags still
set (and mistakenly clear some tiles in the new surface).
Fixes fd.o bug 26932.

When the paint is color, paint_bind_samplers binds a dummy sampler
without a texture. It causes demos requiring a sampler (those use a
mask or an image) to crash.

Wait for threads to exit before cleaning up per-thread data.

Note that only the PIPE_TEX_WRAP_CLAMP,CLAMP_TO_EDGE,CLAMP_TO_BORDER
modes work with non-normalized texcoords.
|
|
CLAMP_TO_BORDER and CLAMP_TO_EDGE were doing the same thing.

These extensions are not quite useful until the client APIs gain support
for the respective EGLImage extensions.

get_param can be used to query the parameters of a native display.
There is only NATIVE_PARAM_USE_NATIVE_BUFFER right now. It queries
whether the window/pixmap surfaces use the native buffers instead of
private buffers.
|
|
native.h is getting more and more complex. Move the independent modeset
interface to native_modeset.h to simplify native.h a little.
|
|
There is only invalid_surface event right now. When EGL receives the
event, it sets the force_validate flag of the context binding to the
surface. This helps skip an unnecessary check.

The progs/test/texwrap demo looks pretty good, but there are still some
tiny differences from softpipe. There may be a sub-pixel texcoord
interpolation error somewhere.
There's some room for optimization. Many of the wrap modes compute
intermediate values that are constant for the texture size (see the
min/max values). These could be computed earlier and stored somewhere
for later use.

Wine tends to pessimistically use ~0 for its max index, but r300s
only can go up to 2^24-1, causing the kernel checker to freak out.
Civ4 is marginally improved now. Still crashes, but not as bad.
|
|
All the texture wrap modes are now implemented for linear and nearest
sampling.
However, texture border color is not yet supported so some wrap modes
will produce int coords outside the texture bounds. We'll get garbage
values insted of the texture border color for now.
