don't enable APPLE_client_storage, TDFX_texture_compression_FXT1,
EXT_cull_vertex, NV_vertex_program, NV_vertex_program1_1 -
the latter two might work somewhat with some luck.
Also don't enable ARB_imaging.
We could use single 1 bit conditions for scalar masks, but a lot of code
expects masks. The compiler easily optimzes away masks
extensions/truncations so consistency is preferable.
We can revisit this when LLVM backends have more support for vector
conditions.
Extensions were enabled in both st/mesa and st/dri, with st/dri completely
overriding the decisions of st/mesa and exposing even the extensions claimed
to be unsupported by a pipe driver.
This commit moves the differences between the two to st/mesa and removes
the responsibilty of advertising extensions from st/dri.
The new lp_build_sample_general() function will handle all sampling
modes for all texture types. Still incomplete, but a few additional
sampling modes are now supported.
1D textures should work and most of the code for 3D textures is in place.
No support for cube maps yet. No support for different min/mag filters.
Reemitting dirty states on flush causes problems if the GL context
isn't fully consistent when we get to it. It didn't serve any specific
purpose, so, use nouveau_bo_state_emit instead.
Saves an instruction in PINTERP, LINTERP, and PIXEL_W from
brw_wm_glsl.c For non-GLSL it isn't used yet because the deltas have
to be laid out differently.
Otherwise we use glRead/DrawPixels to copy the off-screen FBO image
into the window.
Looks like NVIDIA's broken when using -c (the image is upside down),
but OK with -c -t.
NVIDIA's driver requires that the texture that we're going to render into
be complete. Need to set min/mag filters to non-mipmap modes.
Plus added other error/debug checks.
The bad response length would hang the GPU with a masked sample in a
shader using control flow. For 8-wide, the response length is always
4, and masked slots are just not written to. brw_wm_glsl.c already
allocates registers in the right locations.
Fixes piglit glsl-fs-bug25902 (fd.o bug #25902).
