w/GL_OES_geometry_shader
Originally this patch added the checks to allow the draw calls with XFB,
but commit 2dabd497 beat me to it.

The checks in _mesa_has_shader_subroutine are slightly different than
_mesa_has_ARB_shader_subroutine, but they're not different in a way
that matters. The only way to have ctx->Version >= 40 is if
ctx->Extensions.ARB_shader_subroutine is set.

GL_DOT3_RGB_EXT and GL_DOT3_RGBA_EXT. are nearly identical to
GL_DOT3_RGB and GL_DOT3_RGBA. The only difference is the _EXT
versions do not apply the post-scale. Just smash logscale to 0 so
that RC_OUT_SCALE_1 is always used.
NOTE: I have not actually tested this.

Fixes long standing bug on NV10 and NV20 where using a non-1x RGB or A
post-scale with GL_DOT3_RGB or GL_DOT3_RGBA texture environment would
not work.
The old combiner math uses HALF_BIAS_NORMAL and HALF_BIAS_NEGATE. The
GL_NV_register_combiners defines these as
HALF_BIAS_NORMAL_NV max(0.0, e) - 0.5
HALF_BIAS_NEGATE_NV -max(0.0, e) + 0.5
In order to get the correct result from the dot-product, the
intermediate dot-product must be multiplied by 4. This is a literal
implementation of the GL_ARB_texture_env_dot3 spec. It also requires
using the register combiner post-scale. As a result, the post-scale
cannot be used for the post-scale set by the application.
The new combiner math uses EXPAND_NORMAL and EXPAND_NEGATE. The
GL_NV_register_combiners defines these as
EXPAND_NORMAL_NV 2.0 * max(0.0, e) - 1.0
EXPAND_NEGATE_NV -2.0 * max(0.0, e) + 1.0
Since this fully expands the value to [-1, 1] range, the intermediate
dot-product result is the desired value. This leaves the register
combiner post-scale available for application use.
NOTE: I have not actually tested this.

This is a direct port of Marek Olšáks patch
"radeonsi: increase performance for DRI PRIME
offloading if 2nd GPU is CIK or VI" to r600.
It uses SDMA for the detiling blit from renderoffload VRAM
to GTT, as SDMA is much faster for tiled->linear blits from
VRAM to GTT.
Testing on a dual Radeon HD-5770 setup reduced the time
for the render offload gpu to get its rendering into
system RAM from approximately 16 msecs for simple rendering
at 1920x1080 pixel 32 bpp to 5 msecs, a > 3x speedup!
This was measured using ftrace to trace the time the radeon kms
driver waited on the dmabuf fence of the renderoffload gpu to
complete.
All in all this brought the time for a flip down from 20 msecs
to 9 msecs, so the prime setup can display at full 60 fps instead
of barely 30 fps vsync'ed.
The current r600 implementation supports SDMA on Evergreen and
later, but not R600/R700 due to some bugs apparently present
in their SDMA implementation.

required for the ARB_stencil_texturing extension. We'll make a copy of
the stencil data into a new texture that we can sample using the

SDMA is much faster for tiled->linear blits from VRAM to GTT.
I have Bonaire in my second PCIe slot.
$ glxinfo | grep OpenGL.renderer
OpenGL renderer string: Gallium 0.4 on AMD TONGA ...
$ DRI_PRIME=1 glxinfo | grep OpenGL.renderer
OpenGL renderer string: Gallium 0.4 on AMD BONAIRE ...
Without SDMA:
$ DRI_PRIME=1 glxgears
8796 frames in 5.0 seconds = 1759.074 FPS
8899 frames in 5.0 seconds = 1779.672 FPS
With SDMA:
$ DRI_PRIME=1 glxgears
12765 frames in 5.0 seconds = 2552.788 FPS
12888 frames in 5.0 seconds = 2577.495 FPS
The 1st GPU is irrelevant. The improvement should be much lower at 60 fps,
but definitely measurable.
SI will get this once we add SDMA blit support for it.
