So other directory can share it.
Also remove the libllvmpipe.a dependency from test
programs. It is not needed any more.

We shouldn't try to clear a non-existant z/stencil buffer, so there's
probably a bug elsewhere. Disable the assertion for now to allow things
to at least run.
We weren't saving the per-scene texture references at the right point.
Fixes piglit cubemap segfault. The segfault resulted from referencing
texture memory which was prematurely freed because of a missed reference
count.
Fixes fd.o bug 27276.
The triangle rasterizer sets this field to indicate front/back-facing.
It gets passed into the generated fragment code as another parameter.
Used now for stencil front/back selection but will also be used for
fragment shaders in general (see TGSI_SEMANTIC_FACE).
With this commit two-sided stenciling mostly works but there's
still a bug or two...
Most stencil demos look OK (modulo some unrelated rendering glitches).
Only single-sided stencil test works at this point.
There are probably some bugs to be found...
The llvm wrapper wasn't really an OS thing.
Use lp_bld.h for now but we eventually should rename/re-prefix all the
files/functions in the gallivm/ directory.
Now that transfers are context objects their sideeffects must happen in
order when used by the state tracker, but that synchronization must be
bypassed when used inside the driver, or it would cause infinite
recursion.
The stride depends on the mipmap level. Rename to row_stride to
distinguish from img_stride for 3D textures.
Fixes incorrect texel addressing in small mipmap levels.
There was very little use for this beyond permitting the
pipe_context::tex_transfer_destroy() function to omit the pipe_context
argument.
This change adds the pipe_context argument into tex_transfer_destroy()
so that it looks like other pipe_context functions, and removes the
pipe_context pointer from pipe_transfer.

glx: permit building with older protocol headers
I'd like to be able to build mesa on current distro releases without
having to upgrade from the standard dri2proto and glproto headers. With
this change I'm able to build on ancient releases such as Ubuntu 9-10...
In general, it would be nice to be able to build-test mesa to check for
unintended breakages without having to follow the external dependencies
of every group working on the codebase.

gallium: New pipe_screen::context_create callback.
CSO can often be null.
For example:
1. at initialization
2. using an util module (u_blit) right after initialization (it will push
state and pop the previous null state)
3. at shutdown time (state shouldn't be bound when being destroyed)
Glean was hitting 2.
Several software rasterizers can make use of this winsys, but there
isn't any reason why the winsys itself should know about them.
This change moves that information into the libgl-xlib target.
Need to fix up other targets making use of this winsys.
While this c99 feature should work with most compilers, valgrind doesn't
really like it, and this only really saves some memory, we don't do this
in similar occasions (like the blend state) neither.

No longer needed, except for nouveau and egl/xll/native_ximage.c.
Fix for nouveau is to keep the call, but move it to an internal

Fix for that egl/x11 relies on gallium-sw-api branch or its successor.

drm_api: wrap comment
Change the texture data_ptr from just a single image pointer to an
array of image pointers, indexed by mipmap level.
We'll use this for mipmap filtering.
For now, the mipmap level is hard-coded to zero.
Promote the llvmpipe winsys more or less unchanged to
state_trackers/sw_winsys.h.
Some minor breakages:
- softpipe::texture_blanket is broken, but scheduled for removal anyway.
- haven't fixed up g3vdl yet.
Move transfer creation and mapping to the "scene" object, and out of
the rasterizer. The rasterizer operates on already-mapped
framebuffers only, and no longer needs a screen or context pointer.
The scene object has access to a pipe_context, and this reorg prepares
for moving transfer functionality from the screen to the context.
Introduce a new shared usage and rename primary to scanout.
The display target usage is more of a windows concept and
doesn't mean the same thing as shared. Display target means
that the surface should be presentable, for softpipe this
means that it should be backed by a hardware buffer.
Should work correctly for all pixel formats except SRGB formats.
Generated code made much simpler by defining the pixel format as
a C structure. For example this is the generated structure for
PIPE_FORMAT_B6UG5SR5S_NORM:
union util_format_b6ug5sr5s_norm {
uint16_t value;
struct {
int r:5;
int g:5;
unsigned b:6;
} chan;
};
Not used everywhere yet because it seems compiled code is slower than
bitshift arithmetic by some misterious reason. So we should generate
bitshift arithmetic at least for the simple UNORM pixel formats.
Due to the u_format.csv changes the unrolled code generator was being used
for formats it didn't support.
Bring some bugfixes from u_format_access.py too.
Need to compute two masks here for full and partial 16x16 blocks.
Gives a further good improvement for isosurf particularly:
isosurf 97 -> 108
gears 597 -> 611
with mutable vars we don't need to follow the phi nodes. meaning that
control flow becomes trivial as we don't have scan the rest of the tgsi
to figure out the variable usage anymore. futhermore the memory2register
pass promotes alloca/store/load to registers while inserting the right phi
nodes. so we get simplicity and performance.
the llvmpipe tgsi translation is a lot more complete than what was in
gallivm so replacing the latter with the former. this is needed since
the draw llvm paths will use the same code. effectively the proven
llvmpipe code becomes gallivm.

trace: expose the wrapped context's priv data
If we are going to keep this priv idea, really want an accessor
function for it so that trace and other drivers can wrap that.

glx: permit building with older protocol headers
I'd like to be able to build mesa on current distro releases without
having to upgrade from the standard dri2proto and glproto headers. With
this change I'm able to build on ancient releases such as Ubuntu 9-10...
In general, it would be nice to be able to build-test mesa to check for
unintended breakages without having to follow the external dependencies
of every group working on the codebase.

gallium: New pipe_screen::context_create callback.
This fixes a regression when the geometry shaders branch was merged
to master with commit 89d8577fb3.
progs/demos/pointblast and progs/redbook/anti work again.
Changes in v3:
- Renumber caps to accomodate caps to add to master in the meantime
- Document caps
- Add unsupported caps to *_screen.c too
Changes in v2:
- Split for properties patch
- Use positive caps instead of negative caps
This adds 4 caps to indicate support of each of the fragment coord
conventions.
All drivers are also modifed to add the appropriate caps.
Some drivers were incorrectly using non-Gallium-default conventions,
and caps for them have them set so that they will behave correctly
after the later state tracker patches.
This drivers are softpipe/llvmpipe (uses integer rather than half
integer) and pre-nv50 Nouveau (uses lower left rather than upper left).
Other drivers might be broken. With this patchset, fixing them is
only a matter of exposing the appropriate caps that match the behavior
of the existing code.
Drivers are encouraged to support all conventions themselves for better
performance, and this feature is added to softpipe in a later patch.
Currently counting number of tris, how many tiles of each size are
fully covered, partially covered or empty, etc.
Set LP_DEBUG=counters to enable. Results are printed upon context
destruction.
The code which converts/copies color tiles to the linear layout has
been rewritten. There's less arithmetic and better loop unrolling,
and possibly a better memory access pattern.
Some demos, like gears, are about 20% faster now.
When we know that a 4x4 pixel block is entirely inside of a triangle
use the jit function which omits the in/out test code.
Results in a few percent speedup in many tests.
The scissor test is implemented as another per-quad operation in
the JIT code. The four scissor box params are passed via the
lp_jit_context. In the JIT code we compare the quad's x/y coords
against the clip bounds and create a new in/out mask that's AND'd
with the main quad mask.
Note: we should also do scissor testing in the triangle setup code
to improve efficiency. That's not done yet.
When a texture is used in the scene we add it to a list of texture
references. The lp_scene_is_textured_referenced() function tells
us if a texture is referenced by the scene.
Adjust definition of empty_bin according to what's actually in empty
bins. We often have a state packet before/after load commands.
Still need to do something about the fence packets.
In some corner cases the right-most / bottom-most vertex can be
right on the edge of the framebuffer. Because the maxx, maxy vals
are computed with a series of float/int, pixel/tile transformations
we can end up with maxx >= scene->x_tiles or maxy >= scene->y_tiles.
This leads to putting data into bins that never get processed, or
reset. This becomes stale data that can lead to segfaults.
Clamping fixes this.
Was previously calculating the intersection of the scissor rectangle
and the framebuffer dimensions. Rendering is already restricted to
framebuffer dimensions by other means, so scissor testing (when
implemented) can just use the scissor state directly.
Explain how to build for windows. Both MSVC 9 and cross MinGW supported.
Stop documenting LLVM 2.5 as supported. It still supported at the moment
but it will soon stop being.
When the incoming c0,c1,c2 values are equal to INT_MIN it means that
all pixels are inside the triangle. Thus we can skip the detailed
pixel inside/outside triangle tests. Use the new lp_build_if()/endif()
functions to generate the branching code.
The code is disabled ATM however because it's actually a little slower
than the original code. A little more tuning may fix that though...
Was used only as a reference, since texture sampling is now code generated.
Already axed in the lp-binning branch too.
This fixes the llvmpipe build after recent sampling changes.
The setup tiling engine is now plugged directly into the draw module
as a rendering backend.
Removed a couple of layering violations such that the setup code no
longer reaches out into the surrounding llvmpipe state or context.
This patch removes PIPE_TEX_FILTER_ANISO.
Anisotropic filtering is enabled if and only if max_anisotropy > 1.0.
Values between 0.0 and 1.0, inclusive, of max_anisotropy are to be
considered equivalent, and meaning to turn off anisotropic filtering.
This approach has the small drawback of eliminating the possibility of
enabling anisotropic filter on either minification or magnification
separately, which Radeon hardware seems to support, is currently
support by Gallium but not exposed to OpenGL. If this is actually
useful it could be handled by splitting max_anisotropy in two values
and adding an appropriate OpenGL extension.
NOTE: some fiddling & reformatting by keithw to get this patch to
apply. Hopefully nothing broken in the process.
Not since 6094e79f4e.
Drivers now need to flush draw module explicitely (which explains why
all those previous commits adding draw_flushes calls were necessary).
This is a good thing, but it's tricky to get this right in face of user buffers
(it's not even clear who has the responsibility to flush when a user buffer
is seen -- statetracker or pipe driver), so just force flush (temporarily)
since it's not a bottleneck now.
That is:
- check for no op
- update/flush draw module
- update bound state and mark it as dirty
In particular flushing the draw module is important since it may contain
unflushed primitives which would otherwise be draw with wrong state.
The test to determine which of the pixels in a 2x2 quad is now done in
the fragment shader rather than in the calling C code. This is a little
faster but there's a few more things to do.
Note that the step[] array elements are in a different order now. Rather
than being in row-major order for the 4x4 grid, they're in "quad-major"
order. The setup of the step arrays is a little more complicated now.
So is the course/intermediate tile test code, but some lookup tables
help with that.
Next steps:
- early-cull 2x2 quads which are totally outside the triangle.
- skip the in/out test for fully contained quads
- make the in/out comparison code tighter/faster.
It was pretty confusing having an entity named "bin" and another named
"bins", not least because sometimes there was a need to talk about >1
of the "bins" objects, which couldn't be pluralized any further...
Scene is a term used in a bunch of places to talk about what a binner
operates on, so it's a decent choice here.
use pointer to union instead of void pointer.
gcc complained a lot, depending what the pointer originally actually was.
Looks like it's in fact maybe legal to cast for instance uint pointers to
union pointers as long as union contains a uint type, hence use this with some
callers, other just use union util_color in the first place.
New lp_bins struct contains all bin information.
More move bin-related code into lp_bin.[ch]
Use new/updated bin-access functions to hide implementation details.
The result is more/cleaner separation between the setup and rast components.
This will make double-buffering of the bins easier, etc.
