When an app loads libEGL.so dynamically with RTLD_LOCAL, loading DRI
drivers would fail because of missing glapi symbols. This commit makes
egl_dri2 load libglapi.so with RTLD_GLOBAL to export glapi symbols for
future symbol resolutions.
The same trick can be found in GLX. However, egl_dri2 can only do so
when --enable-shared-glapi is given. Because, otherwise, both libGL.so
and libglapi.so define glapi symbols and egl_dri2 cannot tell which
library to load.
When the user sets EGL_DRIVER to egl_dri2 (or egl_glx), make sure the
built-in driver is used. The user might leave the outdated egl_dri2.so
(or egl_glx.so) on the filesystem and we do not want to load it.
makedepend would crash when a source includes a header indirectly, such
as
#define HEADER "some-header.h"
#include HEADER
Do not define HEADER (makedepend would detects this as an incomplete
include) and add the dependency manually in the Makefile.
This should hopefully fix bug #33374.
For 1D/2D texture arrays use the pipe_resource::array_size field.
In OpenGL 1D arrays texture use the height dimension as the array
size and 2D array textures use the depth dimension as the array size.
Gallium uses a special array_size field instead. When setting up
gallium textures or comparing Mesa textures to gallium textures we
need to be extra careful that we're comparing the right fields.
The new st_gl_texture_dims_to_pipe_dims() function maps OpenGL
texture dimensions to gallium texture dimensions and simplifies
this quite a bit.
This reverts commit d3df641f0a.
The original commit had sat unpushed on my machine for months. By the
time I found it again, I had forgotten that we had decided not to use
this change after all, (the relevant test was removed long ago).
The GLSL specification is vague here, (just says "as is standard for
C++"), though the C specifications seem quite clear that this should
be an error.
However, an existing piglit test (CorrectPreprocess11.frag) expects
this to be a warning, not an error, so we change this, and document in
README the deviation from the specification.
So that 'foo' can be found in: OPTION=prefixfoosuffix,foo
Also allow that debug options can be separated by a non-alphanumeric characters
instead of just commas.
This drops the memblock manager for ZMASK. Instead, only one zbuffer can be
compressed at a time. Note that this does not necessarily have to be slower.
When there is a large number of zbuffers, compression might be used more often
than it was before. It's also easier to debug.
How it works:
1) 'clear' turns the compression on.
2) If some other zbuffer is set or the currently-bound zbuffer is used
for texturing, the driver decompresses it and then turns the compression off.
Notes:
- The ZMASK clear has been refactored, so that only one packet3 is used to clear
ZMASK.
- The 8x8 compression mode is disabled. I couldn't make it work without issues.
- Also removed driver-specific stuff from u_blitter.
Driver status:
- RV530 and R580 appear to just work (finally).
- RV570 should work, but there may be an issue that we don't correctly
calculate the number of dwords to clear, resulting in a partially
uninitialized zbuffer.
- RS690 misrenders as if no ZMASK clear happened. No idea what's going on.
- RV350 may even hardlock. This issue was already present and this patch doesn't
fix it.
I think we are still missing some hardware info we need to make the zbuffer
compression work fully.
Note that there is also an issue with HiZ, resulting in a sort of blocky
zigzagged corruption around some objects.
From the AMD_conservative_depth spec:
If gl_FragDepth is redeclared in any fragment shader in a program, it
must be redeclared in all fragment shaders in that program that have
static assignments to gl_FragDepth. All redeclarations of gl_FragDepth in
all fragment shaders in a single program must have the same set of
qualifiers.
When AMD_conservative_depth is enabled:
* Let 'layout' be a token.
* Extend the production rule of layout_qualifier_id to process the tokens:
depth_any
depth_greater
depth_less
depth_unchanged
