5 years agocompiler/spirv: use 32-bit polynomial approximation for 16-bit asin()
Iago Toral Quiroga [Thu, 31 May 2018 08:34:03 +0000 (10:34 +0200)]
compiler/spirv: use 32-bit polynomial approximation for 16-bit asin()

The 16-bit polynomial execution doesn't meet Khronos precision requirements.
Also, the half-float denorm range starts at 2^(-14) and with asin taking input
values in the range [0, 1], polynomial approximations can lead to flushing
relatively easy.

An alternative is to use the atan2 formula to compute asin, which is the
reference taken by Khronos to determine precision requirements, but that
ends up generating too many additional instructions when compared to the
polynomial approximation. Specifically, for the Intel case, doing this
adds +41 instructions to the program for each asin/acos call, which looks
like an undesirable trade off.

So for now we take the easy way out and fallback to using the 32-bit
polynomial approximation, which is better (faster) than the 16-bit atan2
implementation and gives us better precision that matches Khronos
requirements.

The DDX driver can be notified of adaptive sync suitability by

This property is set on the first swap the application performs
when adaptive_sync is set to true in the drirc.

It's performed here instead of when the loader is initialized for
two reasons:

(1) The window's drawable can be missing during loader init.
    This can be observed during the Unigine Superposition benchmark.

(2) Adaptive sync will only be enabled closer to when the application
    actually begins rendering.

If adaptive_sync is false then the _VARIABLE_REFRESH property
is deleted on loader init.

The property is only managed on the glx DRI3 backend for now. This
should cover most common applications and games on modern hardware.

Vulkan support can be implemented in a similar manner but would likely

5 years agoanv: don't do partial resolve on layer > 0
Lionel Landwerlin [Mon, 3 Dec 2018 18:40:10 +0000 (18:40 +0000)]
anv: don't do partial resolve on layer > 0

We've made the choice not to use fast clears on layer > 0 with
multilayer images. This is partly because we would need to store
multiple clear colors for each layer, making the existing memory
layout, already including aux surfaces, fast clear color, image state,
etc... even more complex.

Partial resolves are the operations transfering the clear colors into
the auxiliary buffers. This operation is currently implemented in
Blorp by loading the clear color from the image's BO, into a shader
that then samples from the auxiliary buffer and writes the color only
if it isn't there already.

The problem here is that because we store only one clear color for all
layers and it is used for partial resolves. If you trigger a partial
clear on a layer > 0, then you're likely to deal with a color that is
not what you actually want. In the particular issues below, we have
multiple layers, each cleared with a different color but the partial
resolve just writes the wrong color into the auxiliary buffers for
layers > 0.
