Provides basic window system integration behind a simple interface,
allowing tests to be written without dependency on either the driver
or window system.
With a lot of work, could turn into something like glut for gallium.

Thanks to Nicolai Hähnle for explaining this register!

We really need to get these into bug reports.

This was missed in commit f7cbaae13d67c55abe81ac230de37f564365099f.

FDO bug #27338.

Kind of surprised that this was as little as it took. Worrying.

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

This reverts commit cba6430524198a1bdcdeada03cbe946a454f3935.
Breaks celestia with a hardlock. :T
We really need to sit down and study texture stuffing further.

Fixes for instance noise with material shaders in FlightGear.

Needed for i915g, also fixed swizzle in draw_vs_aos_io.

Since the winsys isn't shared with i965 and never will be

This reverts commit a9063cad0f0190ff88cd20fbad5aa87bf1a943f6.
Not too surprisingly, this change caused some regressions.
Revert it for the time being.
See fd.o bug 27320.

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.

Jose should probably review this since he wrote the original code.

Avoid emitting fences when not needed.
Speeds up glReadPixels quite a bit when reading image row by row.

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.

On some systems, putting vertex and index buffers in VRAM instead of GART
memory eliminates massive graphics corruption which is otherwise present,
due to unclear causes.
This patch adds an environment variable that does that, along with helpful
messages.
It turns it on by default on G7x, as it is what I am seeing corruption
on and some other reports also seemed to pinpoint these cards.

Currently we allocate buffers in GART or VRAM at creation time.
However, when using swtnl, this results in reads from uncached
memory, which drastically impair performance.
So, for now, cause nouveau_screen.c to not pass any placement flags
to buffer creation, so that the buffers are moved later.
Previously libdrm itself did this, but was changed to not to do it.
This may introduce an extra copy in normal usage, but this currently
does not seem to introduce significant performance degradation.
This will be revisited when pipebuffer is integrated.
Note that for AGP systems, properly solving this may be complex
since currently there is no fast way of reading from GART/VRAM.
We will probably need to try mapping AGP as writethrough and, in
addition, make buffer creation more aware of future buffer usage.

We had fast paths for PIPE_FUNC_LESS and LEQUAL before. To satisfy
OpenGL invariance rules, all depth compare modes should produce the
same fragment Z values.

Currently we are continuously spewing messages about these variables
since we call debug_get_bool_option everytime we want to check their value.
This is annoying, slows things down due to terminal rerendering
and obscures useful messages.
This patch only calls debug_get_bool_option once and caches the result in a
static variable.

This patch re-emits the viewport state on framebuffer or rasterizer
change.
This seems to be necessary on nv3x, but the reason is not fully
understood.
It is quite likely that this isn't really the correct fix, but seems
to work, and makes nv3x much better.

Those paths aren't important anymore, and a debugging warning won't stop
a hardlock anyway.
|

The code was half converted, resulting in texturing being totally broken.

It requires DRM 2.1.0 (e.g. kernel 2.6.34) and is disabled on older ones.
Finally, the texture tiling implementation is now complete. Uff.

There's still no hint of optimization in the shaders, but
we support conditionals, loops and even integer opcodes so
it isn't that big a lie.
|
|
The vertex elements and buffers might not be valid anymore.
|
|
Relocations of per-screen buffers are now emitted directly,
and include the necessary method to get changes in constbuf
addresses committed to the hw.
It should also be a bit cheaper than the way stateobjs emit
relocation markers, use a little less pushbuf space.
|
|
Not sure, but judging by softpipe, this hook was forgotten.
