This forks vbo_get_minmax_index. We need to know the index range when
translating non-native vertices into native ones. There is no other way
around it.

It will use the index buffer soon.

The CS checker doesn't check the regs and the state-tracker-provided values
are not to be trusted.
This also removes the hack for non-zero index bias.
|
|
|
|
| |
It's not really useful to have non-zero there.

Previously we were mapping/unmapping the index buffer each time we
found the restart index in the buffer. This is bad when the restart
index is frequently used. Now just map the index buffer once, scan
it to produce a list of sub-primitives, unmap the buffer, then draw
the sub-primitives.
Also, clean up the logic of testing for indexed primitives and calling
handle_fallback_primitive_restart(). Don't call it for non-indexed
primitives.
v2: per Jose, only map the relevant part of the index buffer with
pipe_buffer_map_range()

Merge may produce incorrect order of operations for r600-eg:
x: inst1 R0.x, ... ; //from current group
...
t: inst0 R0.x, ... ; //from previous group, same destination
Result of inst1 will be lost.
So compare destinations and don't allow this.

Previously a vertex shader that used no samplers would get updated (by
calling the driver's ProgramStringNotify) when a sampler in the
fragment shader was updated. This was discovered while investigating
some spurious code generation for shaders in Cogs. The behavior in
Cogs is especially pessimal because it ping-pongs sampler uniform
settings:
glUniform1i(sampler1, 0);
glUniform1i(sampler2, 1);
draw();
glUniform1i(sampler1, 1);
glUniform1i(sampler2, 0);
draw();
glUniform1i(sampler1, 0);
glUniform1i(sampler2, 1);
draw();
// etc.
ProgramStringNotify is still too big of a hammer. Applications like
Cogs will still defeat the shader cache. A lighter-weight mechanism
that can work with the shader cache is needed. However, this patch at
least restores the previous behavior.

In slow_read_depth_stencil_pixels_separate() we might have separate
depth and stencil buffers or a combined buffer. In the later case,
don't map the buffer twice. This function is used when the depth
scale/bias pixel transfer values are not the defaults.

glspec doesn't say that we should skip the attenuation and spot
calculation for infinite light(Ppli.w == 0). Instead, it gives a same
formula to do the light calculation for both finite light and infinite
light(see page 62 of glspec 2.1.pdf)
Also from the formula (2.4) at page 62 of glspec 2.1.pdf, we can skip
attenuation calculation if Ppli.w == 0.
This would fix all the intel oglc l_sed fail subcases and introduces no
intel oglc regressions.
v2: fix an wrong intendation(comments from Brian).

intelAllocateBuffer() was oblivious to separate stencil buffers. This
patch fixes it to allocate a non-tiled stencil buffer with special pitch,
just as the DDX does.
Without this, any app that attempted to create an EGL surface with stencil
bits would crash. Of course, this affected only environments that used the
builtin DRI2 backend, such as Android and Wayland.
Fixes GLBenchmark2.1 on Android on gen7.
Note: This is a candidate for the 7.11 branch.

I changed the dimensions of the stencil buffer's region, as allocated by
the DDX, at xf86-video-intel commit
commit 3e55f3e88b40471706d5cd45c4df4010f8675c75
dri: Do not tile stencil buffer
But I forgot to make the analogous update to the Intel DRI2 glue in Mesa.
This patch makes that update.
Surprisingly, the mismatch did not cause any bugs. But the mismatch, if
left unfixed, *would* create bugs in the next commit.
Note: This is a candidate for the 7.11 branch.

When calculating the y offset needed for detiling window system stencil
buffers, replace the term
region->height * 2 + region->height % 2 - 1
with
rb->Height - 1 .
The two terms are incidentally equivalent due to some out-of-date,
incorrect code in the Intel DRI2 glue for DDX. (See
intel_process_dri2_buffer_with_separate_stencil(), line ``buffer_height /=
2;``).
Note: This is a candidate for the 7.11 branch (only the intel_span.c hunk).

Don't assert/die if a VBO is too small. Return zero instead. For
debug builds, emit a warning message since this is an unusual situation
that might indicate that there's a bug in the app.
Note that util_draw_max_index() now returns max_index+1 instead of
max_index. This lets us return zero to indicate that one of the VBOs
is too small to draw anything.
Fixes a failure with the new piglit vbo-too-small test.
