Enable support for ARB_texture_env_crossbar in the master extension
list instead of in every single device-specific list.
|

|
|
This patch is a straightforward duplication of the R200 SetTexOffset code,
except that there is no big-endian tx_table[] array.
|
|
|
|
Share almost all code with r500_fragprog now.
This also fixes Piglit's texrect-many test, which means that the compiz
bicubic plugin should work with hardware acceleration now.
|
|
This just makes the use of mklib more consistent throughout Mesa where
we always want to pass the linker and LDFLAGS when we might be making a
shared library.
|
|
Respect the user's choice of shell when running mklib rather than always
using /bin/sh.

When an input is marked in gl_program.InputsRead but is not actually read
in the final program (due to dead-code elimination or whatever), the order
of input registers must still match gl_program.InputsRead. This is done
even more explicitly now.
|
|
This fixes the last r500 bug related to glean/fragProg1.
|
|
Use an abstracted instruction scheduling and register allocation algorithm
that we will be able to share with r300_fragprog.
Unlike the original emit code, this code tries to pair instructions that
only use the RGB part of the ALU with instructions that only use the alpha
part. However, the pairing algorithm still has some shortcomings;
for example, it doesn't generate optimal code for the emulation of LIT.

|
In addition, this pass fixes non-native swizzles.

Currently the installation directories for libraries and headers are
resolved within the install commands. For instance, the libraries will
be installed to $(INSTALL_DIR)/$(LIB_DIR). This limits the flexibility
of the installation, such as when the libraries should be installed to a
subdirectory like /usr/lib/tls.
This adds the make variables $(INSTALL_LIB_DIR) and $(INSTALL_INC_DIR)
to define the locations that the libraries and headers are installed.
For the static configs, this resolves exactly as before to
$(INSTALL_DIR)/include and $(INSTALL_DIR)/$(LIB_DIR). For autoconf, they
are derived directly from the --libdir and --includedir settings.

This fixes a regression introduced by dea8719f0...
|
|
Use the common facilities to convert non-native instructions into native ones.
Worked hard to make the code easier to read (hopefully), by using helper
functions instead of direct manipulation of the machine code.
Fixes two bugs related to FLR and XPD.

Missed the homogenous divide of R by Q before...

multisample enable is enabled by default, however gl mandates multisample
rendering rules only apply if there's also a multisampled buffer.
|
|
This disallows vertex shader texture sampling. See bugs 16157, 13838.
|
|
Since GL_ARB_vertex_buffer_object protocol isn't supported yet, these
changes are innocuous.
|
|
These asserts are of questionable use at the moment with things in flux.

first level of the mipmap. fix #16210
|

This isn't complete yet. It does cover the two most common usage cases,
though, and at least the third one (POINT_DISTANCE_ATTENUATION) is possible,
so I'll do that later.

. There is both a per-texture unit and a per-texture object (at least for
OpenGL 1.4); this should now be supported properly.
. The LOD bias calculation in r300_state has been simplified and corrected
(need to multiply by 32 instead of 31, and ensure clamping)
. do not clamp LOD bias in TexEnv, as that behaviour conflicts with what
the spec says
. set Const.MaxTextureLodBias properly
. remove the no_neg_lod_bias property; if somebody can explain what
it's good for, we can add it back in, but according to Google, nobody
seems to use it
. removed some dead code and unused variables
|

Okay, this time it's for real, and for good. This should be a perma-fix.

Since the gl pkg-config file doesn't convey any specifics about the
backend in use, this adds a new pkg-config file for when DRI is in use.
This can be used by the xserver build to determine if the DRI and/or
GLX extensions are appropriate.

Nothing would get drawn as the negative coordinates broke the rectangle
intersection code that used unsigned ints. Tested with copypix demo and
sliding the copy to the upper left.
|
|
This disables the textured copy implementation on 965, which didn't appear
to work (mesa copypix demo, disable the blit path, move so that regions don't
overlap and textured is used, and you get garbage). If we resurrect this for
i965, I'd rather it used the 915-style metaops instead. Current metaops code
left in place so that whoever picks it up has a reference.

Mesa demos tend to leave blending on but in GL_ONE/GL_ZERO, or
GL_SRC_ALPHA/GL_ONE_MINUS_SRC_ALPHA with a source alpha of 1.0.
|
|
Both had some useful bits for the other.
