The previous behaviour was incorrect, and resulted in EXT_tfp being broken
for DDX drivers that implement the correct behaviour (intel/radeon/nouveau).
In the cases where a fake front buffer is required, the X server will
return one when requesting __DRI_BUFFER_FRONT_LEFT.
The Xorg state tracker (aka modesetting_drv) is likely broken now until
it's modified to match the other drivers.

This ensures that an assertion like
assert(expensive_test());
won't have any penalty on release builds. It also implies that no vital
code should be in assert expressions.

This is just a temporary change until we code generate the tile read/write
functions in runtime. The new code avoids an extra memcpy that exists in
u_tile.c functions, from which lp_tile_soa.c was originally based.
This achieves up to 5% improvement, particularly in frames with
little geometry overlap.

Loop building will be rewritten.

We support array layout too -- if it has a single channel.
|
|
We now have 48 GLX visuals. Pretty soon, we'll have 90+ visuals,
only five of which ever get tested. :3

intel_pixel_read.c: In function ‘do_blit_readpixels’:
intel_pixel_read.c:221: warning: cast from pointer to integer of
different size
Cast via an intermediate (GLintptr) instead and hope the result fits
within GLuint... [It should as we simply do not support textures *that*
large!]

This should catch the common programming error where we attempt to
emit a relocation to beyond the end of the target buffer.

Same as in src/gallium/winsys/drm/intel/xorg/Makefile
Thanks MrCooper for explanations on IRC
[ Summary amended by Michel Dänzer to clarify that this is related to the xorg
state tracker ]

Fixes crash with compiz magnifier plugin.

This ensures the driver won't map the wrong set of textures.

Besides from being necessary to use that extension, it also fixes a crash
when deleting the currently bound vertex array object.

This fixes the glxgears bug, among other things.

If the src renderbuffer is actually a texture, we can directly use that
texture as the src and avoid a copy.

Combined with the previous fix, it takes cairo-gl firefox-talos-gfx time
from 120 seconds to 90 seconds on my GM45.

This reverts commit df058298e1570eea8712f9bb051f674fab2eaf24. It didn't
explain why it was required, doesnt appear to be required, and is a
significant performance penalty for cairo-gl firefox.

no longer used now that the hw supports this natively.
Also, clean up some formatting.
|
|
Currently using max_slots > 1 will cause synchronous rendering
if the driver flushes its command buffers between one bitmap and the
next.
Need to improve buffer_write to allow NO_WAIT (as well as no_flush)
updates to buffers where we know there is no conflict with previous
data.
|
|
Propagate NULL return value.
This also allows removing the DRM_MODE_FEATURE_DIRTYFB specific pixmap
management hacks.
|
|
Asks the driver to map the texture storage directly or return NULL if that's
not possible.
|
|
Always test for PIPE_TRANSFER_READ/WRITE using the bit-wise and operator, and
add a pipe_transfer_buffer_flags() helper for getting the buffer usage flags
corresponding to them.
|
|
Need to check if we'll take the software path so which requires mapping the
src texture image.
Fixes crash in piglit gen-compressed-teximage, bug 24219. However, the
test still does not pass (it may never have).

Interface is pipe_video_context::set_csc_matrix().
vl_csc.h defines some helpers to generate CSC matrices based on one of
the color standard and a user defined ProcAmp (brightness, contrast,
saturation, hue).

This is useful for enabling our GLSL testcases using the 2.0 entrypoints
even though we don't have full GL 2.0.
|
|
Other vendors have enabled ARB_fragment_shader as part of OpenGL 2.0
enablement even on hardware like the 915 with no dynamic branching or
dFdx/dFdy support. But for now we'll leave it disabled because we don't
do any flattening of ifs or loops, which is rather restrictive.
This support is not complete, and may be unstable depending on your shaders.
It passes 10/15 of the piglit glsl tests, but hangs on glean glsl1.

Since the TNL is all done in software anyway, it should be the same to
the user who's probably using ARB_vertex_program otherwise, but gives them
a nicer programming environment.
|
|
This fixes potential heap trashing if the program of choice exceeds limits,
and fixes the native instructions limit being lower than what can be
used by valid programs.
