This might technically not always be correct, because va_copy might
be a function, or a system might not have va_copy, and not work with
assignment.
Hopefully this is never the case.
Without configure tests, it doesn't seem possible to do better.

This commit adds the ability to produce a log file containing all
reference count changes, and object creation/destruction, on Gallium
objects.
The data allows to answer these crucial questions:
1. This app is exhausting all my memory due to a resource leak: where
is the bug?
2. Which resources is this app using at a given moment? Which parts of
the code created them?
3. What kinds of resources does this app use?
4. How fast does this app create and destroy resources? Which parts of
the code create resources fast?
The output is compatible with the one produced by the similar facility
in Mozilla Firefox, allowing to use Mozilla's tools to analyze the data.
To get the log file:
export GALLIUM_REFCNT_LOG=<file>
To get function names and source lines in the log file:
tools/addr2line.sh <file>
To process the log file, see:

Without this, any form of logging that dumps stack traces continuously
will spend a lot of time resolving symbol names.

It is needed to support calling eglGetProcAddress before eglInitialize.

Currently Gallium internals always use PIPE_TEXTURE_2D and normalized
coordinates to access textures.
However, PIPE_TEXTURE_2D is not always supported for NPOT textures,
and PIPE_TEXTURE_RECT requires unnormalized coordinates.
Hence, this change adds support for both kinds of normalization.
|
|
|
|
This seems to make sense, although I suspect the semantics of
TGSI_TEXTURE_RECT need to be closely reviewed.
|
|
Searched for them with:
git grep -E '[!=]=.*PIPE_TEXTURE_2D|PIPE_TEXTURE_2D.*[!=]=|case.*PIPE_TEXTURE_2D'
Behavior hasn't been changed.
|
|
This allows to properly support OpenGL rectangle textures in a well
defined way, especially on drivers that don't expose
PIPE_CAP_NPOT_TEXTURES.

According to Vinson, enabling it causes no regressions

To my knowledge, there is no way to flush zmask and thus write the clear
value.
This fixes zbuffer reads, among other things.

Not sure whether it works now (it is still disabled).

|

Add new source files to SConscripts.

This pretty much ports the code from r600c, however it doesn't
always seem to work quite perfectly, but I can't find anything in this
code that is wrong. I'm guessing either literal input or constants
aren't working always.

Doesn't fix anything, as those indices were both always 0.
|
|
the first two are straight op2's and the DDX/DDY are taken from r600c.
|
|
fixes fp-set-01 and glsl-fs-step
|
|
fixes biased texturing tests
|
|
Don't do perspective for TEX, and also copy input to a temporary for TEX
also add tex opcode names
|
|
makes glsl-fs-log2 and glsl1-integer division with uniform var pass
|
|
fixes piglit pointAtten and point-sprite tests
|
|
This still needs work, passes tex3d, fbo-scissor-bitmap, scissor-bitmap
|
|
We were putting the source pointer in a register used as a temporary,
breaking all paths that don't read the data in a single instruction.
|
|
h needs to be rounded up, this probably needs revisiting when we get
to tiling etc.
fixes fbo-generatemipmap-npot
