[Mesa-dev] RFC: Increase gallium PIPE_MAX_SHADER_INPUTS/OUTPUTS
PIPE_MAX_SHADER_INPUTS/OUTPUTS are currently set to 16 in p_state.h
That's actually not enough to accomodate OpenGL's needs. For example,
a Mesa vertex shader has these inputs:
typedef enum
{
VERT_ATTRIB_POS = 0,
VERT_ATTRIB_WEIGHT = 1,
VERT_ATTRIB_NORMAL = 2,
VERT_ATTRIB_COLOR0 = 3,
VERT_ATTRIB_COLOR1 = 4,
VERT_ATTRIB_FOG = 5,
VERT_ATTRIB_COLOR_INDEX = 6,
VERT_ATTRIB_POINT_SIZE = 6, /*alias*/
VERT_ATTRIB_EDGEFLAG = 7,
VERT_ATTRIB_TEX0 = 8,
VERT_ATTRIB_TEX1 = 9,
VERT_ATTRIB_TEX2 = 10,
VERT_ATTRIB_TEX3 = 11,
VERT_ATTRIB_TEX4 = 12,
VERT_ATTRIB_TEX5 = 13,
VERT_ATTRIB_TEX6 = 14,
VERT_ATTRIB_TEX7 = 15,
VERT_ATTRIB_GENERIC0 = 16,
VERT_ATTRIB_GENERIC1 = 17,
VERT_ATTRIB_GENERIC2 = 18,
VERT_ATTRIB_GENERIC3 = 19,
VERT_ATTRIB_GENERIC4 = 20,
VERT_ATTRIB_GENERIC5 = 21,
VERT_ATTRIB_GENERIC6 = 22,
VERT_ATTRIB_GENERIC7 = 23,
VERT_ATTRIB_GENERIC8 = 24,
VERT_ATTRIB_GENERIC9 = 25,
VERT_ATTRIB_GENERIC10 = 26,
VERT_ATTRIB_GENERIC11 = 27,
VERT_ATTRIB_GENERIC12 = 28,
VERT_ATTRIB_GENERIC13 = 29,
VERT_ATTRIB_GENERIC14 = 30,
VERT_ATTRIB_GENERIC15 = 31,
VERT_ATTRIB_MAX = 32
} gl_vert_attrib;
With PIPE_MAX_SHADER_INPUTS=16 there's potentially little or no space
left for any user-defined inputs if most of the conventional
attributes are used.
I propose bumping these limits to 32 each. Any concerns?

Sounds good. There's also the confusingly almost related value
"PIPE_MAX_ATTRIBS" which is already 32.

I think the first actually responds to GL_MAX_VARYING_FLOATS * 4, the other to
GL_MAX_VERTEX_ATTRIBS. They're both actually safe minimums, GL says that the
first one needs to be at least 8, the other needs to be at least 16. So our
values just double the minimum. We probably should have hardware queries for
both. Also increasing PIPE_MAX_SHADER_INPUTS to 32 sounds good.

Sounds fine. We probably do need caps.

[Mesa-dev] r300 compiler scheduler fixes
This patch and also http://lists.freedesktop.org/archives/mesa-dev/2010-July/001252.html should fix all the outstanding scheduler bugs. This patch adds a register rename pass that converts the code into quasi-SSA form, which makes it easier for the scheduler to schedule TEX blocks. This fixes: https://bugs.freedesktop.org/show_bug.cgi?id=28606 If there are no major objections to these, I'll push them to master. -Tom ___ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
[Mesa-dev] [PATCH] r300/compiler: Add a register rename pass.
This pass renames register in order to make it easier for the pair
scheduler to group TEX instructions together.
