It's bound to be useful elsewhere.

Two integers were being operated on as
a vector of floats in draw_llvm_generate().
This bug got uncovered by fixing this bug:

Assert that "first" is always smaller than "count" and add reasoning.
It would be better to simply fix trim(), but it is used in tight loops
right now.
|
|
Some primitives with adjacency have their "incr" wrong.
|
|
642d5ba79abc6a231a5fdabb3454b9b082b0d7f8 removed flags masking for
vertices other than the first one. Add assertions to be on the safe
side.
|
|
Do not expand LOCAL_VARS to void expression. Otherwise, declarations
and code will be mixed when more variables are declared in FUNC_ENTER.
This fixes fdo bug #29416.

Vertex flags are a contract between vcache and the pipeline. They are
set only for the first vertex of a primitive.
|
|
This fixes out-of-bound access to the vertices.
|
|
Use draw_decompose_tmp.h to replace pipeline primitive decomposer.
|
|
Use draw_decompose_tmp.h to replace stream out primitive decomposer.
|
|
Use draw_decompose_tmp.h to replace GS primitive decomposer.
|
|
Use draw_decompose_tmp.h to replace vcache primitive decomposer. As the
new decomposer supports primitives with adjacency, vcache_triangle_adj
and vcache_line_adj (and their variants that have flags) are added.
|
|
Including draw_decompose_tmp.h defines a primitive decomposer. It is
intended to replace the existing vcache/so/gs/pipe decomposers.
This is based on draw_pt_vcache_tmp.h.

This implements fast Z clear, Z compression, and HiZ support for r300->r500
GPUs.
It also allows cbzb clears when fast Z clears are being used for the ZB.
It requires a kernel with hyper-z support.
Thanks to Marek Olšák <maraeo@gmail.com>, who started this off, and Alex Deucher at AMD for providing lots of hints.
v2:
squashed zmask ram size fix]
squashed r300g/blitter: fix Z readback when compressed]
v3:
rebase around texture changes in master - .1 fix more bits
v4:
migrated to using u_mm in r300_texture to manage hiz/zmask rams consistently
disabled HiZ when using OQ
flush z-cache before turning hyper-z off
update hyper-z state on dsa state change
store depthclearvalue across cbzb clears and replace it afterwards.

Fixes typo from commit b609cfc7c9c38f26e7e6d6f7dd5dd6d38f4ed209.

This bug can be triggered by rendering polygons with
glProvokingVertexEXT(GL_FIRST_VERTEX_CONVENTION_EXT);
glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);

When we have instance divisors we don't really know which vertex
elements we'll be fetching ahead of time.
This fixes a bug in instanced drawing which was exposed by the new
draw_vbo() code because of max_index not being ~0 as often as it used
to be. The test for max_index >= DRAW_PIPE_MAX_VERTICES often hid
this problem before.
|
|
Plus more debug code and do clamping in generic_run().

Apparently, we must always use integers to perform calculations,
otherwise the results won't match D3D's CxV8U8 definition.
|
|
Not sure if this will actually fix the issue, but it fixes the warning.
|
|
we just have nothing to do in it right now
|
|
|
|
|
|
Keep min_index and max_index at their defaults (0 and ~0).
|
|
|
|
|
|
Make sure that all the element indexes actually lie inside the vertex
buffer.
Also, rename pipe_run() to pipe_run_elts() to be more specific.
And assert/check the vertex count for the non-indexed case.
|
|
|
|
Plumb the constant buffer sizes down into the tgsi interpreter where
we can do bounds checking. Optional debug code warns upon out-of-bounds
reading. Plus add a few other assertions in the TGSI interpreter.

This reverts commit 5f90e76c54bbf4456c977b3cbca450d7a570179e.
Bad cherry-pick.
|
|
If y==NULL and y_stride==NULL it means the texture is 1D. Return
zero for out_i and the offset instead of garbage.
|
|
Useful for packing mask values.
|
|
Less susceptible to be broken.
