The non-KMS interface is to blame here. In theory, a proper fix
could be produced that works for the KMS interface only, but it
require cleaning a lot of mess. Easier to just do it right in r300g.

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.

|
If we deleted a currently bound texture, we were always reverting the texture
binding to the default 1D texture rather than the proper default texture.
|
|
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).

The parameter is a bitmask.

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.
|
|
Previously, we were doing it in the midst of the pipeline run, which gave
an opportunity to enable/disable fallbacks, which is certainly the wrong
time to be doing so. This manifested itself in a NULL dereference for PutRow
after transitioning out of a fallback during a run_pipeline in glean glsl1.
|
|
This reverts commit e7044d552c6d16389447880b8744a51de1cf0199. It
prevented the driver from ever recovering from a software fallback due
to a program error. The original bug it claimed to fix doesn't appear to
exist post-revert.
|
|
Previously, we'd go trashing the heap.
|
|
It's misleading to report things like the program having too many native
instructions as a Mesa implementation error, when the program may just be
too big for the hardware.

lim x->0 log(x) = -inf so -FLT_MAX is a better approximation than 0
for LG2(0).
