If a GL function is called w/out a current rendering context, this stub
gets called. It should return 0 so that non-void-valued functions return
0/NULL instead of a random number.
R300_PVS_MAX_CONST_ADDR field holds highest const addr, not
const count.
Fixes missing models and others rendering errors for vertex
program using 256 params.
It may happen that the vertex attribute we were going to stuff
the wpos/fog attrs in was already written by vertex program.
In such cases we need to remove instruction accessing these
attributes, so they don't overwrite the wpos/fog related
instructions.
This fixes non-textured models in many wine games.
We're still abusing the flags by putting them where our driver stores
ctx->NewState changes. Making them into more restricted state change
flags would be a project for later.
Fixes a failure where calling intel_draw_buffer() too often would trip
up Mesa assertions about when Mesa state could get changed, when it hadn't.
Bug #27034.
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.
Fixes progs/demos/singlebuffer.c
This can happen when an X window is destroyed behind our back. We use
DRI2CopyRegion behind the scenes in many places (like flushing the fake
front to the real front) so we have to ignore X errors triggered in that
case.
The glean test cases trigger this consistently as they don't destroy the
GLX drawable nicely, they just destroy the X window.
Flush in middle of rendering in KMS is not allowed because
buffers are discarded in flush.
Fixes crash when emiting split indices with RADEON_DEBUG=all.
Flush after transition would emit wrong state that could cause
wrong state emited for pending rendering operation.
Fixes wan once from extrement tuxracer that is using per vertex
materials.
vbo_split_copy was passing one past the max_index to draw function
which caused _tnl_draw_prims function to read uninitialized values
from copied array.
Bug was spoted in valgrind report of progs/tests/cva_huge.
When running this test case in valgrind report includes read of unitialized
value in _tnl_draw_prims. The bug doesn't cause any vissible errors.
Bug is caused by vbo_split_copy that is calling draw function with max_index
one past the end instead of the end.
The bug is triggered by 41a87a43e1.
glBlitFramebuffer, for example, is an alias to the non-static
glBlitFramebufferEXT. We should define glBlitFramebuffer as an alias to
_dispatch_stub_NNN.
