Gawain doesn't include Blender's cross-platform "inline" definition. This change slipped in as part of D2697.

UNIFORM_NONE should never match a valid uniform (builtin or custom).
The logic for UNIFORM_CUSTOM was just wrong, since it returned the first custom uniform. This function should only accept builtin (non-custom) uniforms.
|
|
Quick hash rejection instead of string comparison. Uniform lookups already work this way. I don't expect a major overall speedup since attributes are looked up less frequently than uniforms.

The issue was caused by usage of address of dupli-object (which will vary
from iteration process to iteration process) as something denoting whether
we've got the data synchronized to Cycles or not.
For now solved by using address of original object (the one DupliObject
points to) as a pointer for the map.
Need to do more thoughts about this.

This commit extends the work from Dalai made around scene iterators to
support iterating into objects from dupli-lists.
Changes can be summarized as:
- Depsgraph iterator will hold pointer to an object which created current
duplilist. It is available via `dupli_parent` field of the iterator.
It is only set when duplilist is not NULL and guaranteed to be NULL
for all other cases.
- Introduced new depsgraph.duplis collection which gives a more extended
information about depsgraph iterator. It is basically a collection on top
of DEGObjectsIteratorData.
It is used to provide access to such data as persistent ID, generated space
and so on.
Things which still needs to be done/finished/clarified:
- Need to introduce some sort of `is_instance` boolean property which will
indicate Python and C++ RNA that we are inside of dupli-list.
- Introduce a way to skip dupli-list for particular objects.
So, for example, if we are culling object due to distance we can skip all
objects it was duplicating.
- Introduce a way to skip particular duplicators.
So we can skip iterating into particle system.
- Introduce some cleaner API for C side of operators to access all data such as
persistent ID and friends.
This way we wouldn't need de-reference iterator and could keep access to such
data really abstract. Who knows how we'll be storing internal state of the
operator in the future.
While there is still stuff to do, current state works and moves us in the proper
direction.

Before this change Gawain was doing list lookup twice,
doing string comparison of every and each input which
is not efficient and not friendly for CPUs with small
cache size.
Now we store hash of input name together with actual
name and compare hashes first. Additionally, we do
everything in a single pass which is much better from
cache coherency point of view.
This brings Eevee cache population time from 80ms to
60ms on my desktop and from 800ms to 400ms for Clement
when navigating in a file from T50027.

Denoising was setting session parameters for every frame, which was detected as
a change and therefore caused a resync.
Since the parameter modification change is only needed for viewport rendering
(which doesn't support denoising anyways) and resyncing after a frame change
(which isn't affected by denoising settings), an easy fix is to just ignore
the denoising parameters like it's currently done with the samples.

Follow up to 9f044cb422c1fc9ad79278092445f612342abb59
These comments described the difference between Microsoft & MinGW's struct definition. Now that we dropped MinGW we don't need to go into these details.

Was a mistake in previous changes.
Weirdly enough, frame reading assumes cache_key is always non-NULL..

The Issue
=======
For a long time now MinGW has been unsupported and unmaintained and at this point,
it looks like something that we should just leave behind and move on.
Why Remove
==========
One of the big motivations for MinGW back in the day is that it was free compared to MSVC which was licensed based.
However, now that this is no longer true we have basically stopped updating the need CMake files.
Along with the CMake files, there are several patches to the extern libs needed to make this work. For example, see:
https://developer.blender.org/diffusion/B/browse/master/extern/carve/patches/mingw_w64.patch
If we wanted to keep MinGW then we would need to make more custom patches to the external libs and
this is not something our platform maintainers are willing to do.
For example, here is the patches needed to build python: https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-python3
Fixes T51301

This feature got lost with new auto-track API,
Added it back by extending frame accessor class. This isn't really
a frame thing, but we don't have other type of accessor here.
Surely, we can use old-style API here and pass mask via region
tracker options for this particular case, but then it becomes much
less obvious how real auto-tracker will access this mask with old
style API.
So seems we do need an accessor for such data, just matter of
finding better place than frame accessor.

Not as if i'm totally fine with such style, but i'd better be consistent
with whatever the project is using.

This function is not performance critical, but I prefer the branch-free code and no hack needed to appease gcc.

Seems re-loading module invalidates memory pointers by the looks of it,
which gives an error on the next kernel call.
Not sure how to move memory pointer from one CUDA module to another one,
so for now simply disabling kernel re-load for CUDA devices. Not ideal,
but better than failing render.
Feature-selective option for CUDA is not an official feature anyway.

Goal is to make most of the API independent of OpenGL, Vulkan, any other backend.
Able to remove default case from ElementList_size because IndexType only covers index types. Not that and *everything else* like GLenum.

@fclem does this work for you?

Modern GL's glMapBufferRange works the same on all platforms.

This format is part of OpenGL 3.3, and one of the reasons for choosing 3.3 over 3.2.
Instead of checking #if USE_10_10_10 just use it wherever needed.

Volume shaders without anything connected to the surface output are treated
as if they had a transparent BSDF as the surface shader in Cycles, so the
denoiser should skip feature pass writing for them just as it does with an
actual transparent BSDF.
|
|
If the central pixel is an outlier, the denoiser is supposed to predict its
value from the surrounding pixels. However, in some cases the confidence
interval test would reject every single surrounding pixel, which leaves the
model fitting with no data to work with.

- Some arguments were inapproriatry tagged as unused
using (void)foo semantic.
Only use such semantic in tricky casses, when something
needs to be ignored in release builds or something is
dependent on tricky ifndef policy.
For rest of the cases just use void foo(int /bar*/)
semantic, which ensures variable is not used. Solves
confusion and code running out of sync with later
development.
- Used proper unused semantic to some arguments.
- Added braces to make code easier to follow, tricky
indentation with ifdef, uh.

Use to avoid accidental missing break statements,
use ATTR_FALLTHROUGH to suppress.
