8 years agonouveau: Fix non-1x post-scale factor with DOT3 combiner
Ian Romanick [Thu, 18 Aug 2016 09:57:44 +0000 (10:57 +0100)]
nouveau: Fix non-1x post-scale factor with DOT3 combiner

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.

8 years agor600: increase performance for DRI PRIME offloading if 2nd GPU is Evergreen+
Mario Kleiner [Fri, 26 Aug 2016 16:59:05 +0000 (18:59 +0200)]
r600: increase performance for DRI PRIME offloading if 2nd GPU is Evergreen+

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.

radeonsi: increase performance for DRI PRIME offloading if 2nd GPU is CIK or VI

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.

i965: Embrace "unlimited" GTT mmap support

From about kernel 4.9, GTT mmaps are virtually unlimited. A new
parameter, I915_PARAM_MMAP_GTT_VERSION, is added to advertise the
feature so query it and use it to avoid limiting tiled allocations to
only fit within the mappable aperture.

A couple of caveats:

 - fence support is still limited by stride to 262144 and the stride
needs to be a multiple of tile_width (as before, and same limitation as
the current 3D pipeline in hardware)

 - the max_gtt_map_object_size forcing untiled may be hiding a few bugs
in handling of large objects, though none were spotted in piglits.

See kernel commit 4cc6907501ed ("drm/i915: Add I915_PARAM_MMAP_GTT_VERSION

glsl: Add a lowering pass to handle advanced blending modes.

Many GPUs cannot handle GL_KHR_blend_equation_advanced natively, and
need to emulate it in the pixel shader.  This lowering pass implements
all the necessary math for advanced blending.  It fetches the existing
framebuffer value using the MESA_shader_framebuffer_fetch built-in
variables, and the previous commit's state var uniform to select
which equation to use.

This is done at the GLSL IR level to make it easy for all drivers to
implement the GL_KHR_blend_equation_advanced extension and share code.

Drivers need to hook up MESA_shader_framebuffer_fetch functionality:
1. Hook up the fb_fetch_output variable
2. Implement BlendBarrier()

Then to get KHR_blend_equation_advanced, they simply need to:
3. Disable hardware blending based on ctx->Color._AdvancedBlendEnabled
4. Call this lowering pass.

Very little driver specific code should be required.

i965: Safely iterate the predecessors of the end block.

We want to insert code in each of the predecessors of the end block.
This code includes a nir_if, which would split the block, altering
the set.  To avoid that, I emitted a dead constant at the end of each
block before splitting it, so that the set of predecessors remained
unchanged.  This was admittedly ugly.

Connor suggested instead saving a copy of the set, so we can iterate
it safely.  This is also a little ugly, but a much better plan.

Jason suggested adding an assert(function->impl) here.  All callers
of this function actually want ->impl, so I decided just to change
the API.

We also change the nir_lower_io_to_temporaries API here.  All but one
caller passed nir_shader_get_entrypoint(), and with the previous commit,
it now uses a nir_function_impl internally.  Folding this change in
avoids the need to change it and change it back.

v2: Fix one call I missed in ir3_compiler (caught by Eric).

The reason why it was safe for the scheduler to ignore the side
effects of framebuffer write instructions was that its side effects
couldn't have had any influence on any other instruction in the

writes were always non-overlapping.  We need actual memory dependency
