Previously this was only available as a build options, making it
difficult to get user feedback when NDOF events didn't work as expected.
Now logging can be enabled with:

DDS files coming through OIIO needed a similar treatment as TGA in
T99565; just for DDS OIIO just never set the "unassociated alpha"
attribute. Fixes T101850.

- Use `_` suffix for private members.
- Use `wl_` prefix for Wayland native types to help distinguish
them from local types.
- Replace single character names `d` & `w` with `display` `window`.
- Rename `selection` to `clipboard`. Using the primary selection as a
clipboard is a separate and as yet unsupported feature.
These functions are almost identical, the main difference being
BLI_join_dirfile didn't trim existing slashes when joining paths
however this isn't an important difference that warrants a separate
function.
Using varargs had the disadvantages, replace with a macro which has
some advantages.
- Arguments are type checked.
- Less verbose.
- Unintended NULL arguments would silently terminate joining paths.
- Passing in a NULL argument warns with GCC.
This was a floating point precision issue - or, to be more precise,
an issue with how Cycles split floats into the integer and fractional
parts for Perlin noise.
For coordinates below -2^24, the integer could be wrong, leading to
the fractional part being outside of 0-1 range, which breaks all sorts
of other things. 2^24 sounds like a lot, but due to how the detail
octaves work, it's not that hard to reach when combined with a large
scale.
Since this code is originally based on OSL, I checked if they changed
it in the meantime, and sure enough, there's a fix for it:
https://github.com/OpenImageIO/oiio/commit/5c9dc68391e9
So, this basically just ports over that change to Cycles.
The original code mentions being faster, but as pointed out in the
linked commit, the performance impact is actually irrelevant.
I also checked in a simple scene with eight Noise textures at
detail 15 (with >90% of render time being spent on the noise), and
the render time went from 13.06sec to 13.05sec. So, yeah, no issue.
Test kernel will now test functionalities related to kernel execution
with USM memory allocations instead of with SYCL buffers and accessors
as these aren't currently used in the backend.
This change removes CMake code for automatic calculation of the number
of offline device compiler instances, to hand over control to developers
instead as it incurs a rather large memory usage with around 8GB per
instance at peak.
Use SYCL_OFFLINE_COMPILER_PARALLEL_JOBS CMake variable to configure it.
Currently Cycles uses zero as a default radius when no "radius"
attribute exists. This is more confusing than helpful. Instead,
use the same default radius as EEVEE and Workbench.
This patch enables MNEE on macOS >= 13. There was an inefficiency in the calculation of spill requirements, fixed as of macOS 13. This patch also adds a temporary inlining workaround for a Metal compiler bug which causes `mnee_compute_constraint_derivatives` to behave incorrectly.

- Support switching between libdecor and xdg_shell at run-time.
- Require libdecor when using gnome-shell, otherwise use xdg_shell.
- Gnome-shell detection checks for a gtk_shell* interface which
isn't ideal however it's not possible to check server-side-decorations
are supported without first creating a window.
- Unload Wayland libraries when Wayland fails to load.
For some compiler and linker configurations, linking would fail as the
wayland libs were linked at a high level and not at the actual code
where they were needed.
After talking to Campbell, we decided to clean up this part and now
only link both the X11 and Wayland libs where they are used.
Previously only failure to dynamically load libdecor would report a
warning. Now report failure to load all Wayland libraries.
This was done because Wayland libraries (besides libdecor) are likely to
be installed on systems running Wayland. However it makes it difficult
to troubleshoot failure to load Wayland on systems with libdecor.
Only silence Wayland dynamic loading warnings when Wayland isn't running.
The issue here was that PathTraceWork was set up before checking if
any error occurred, and it didn't account for the dummy device so
it called a non-implemented function.
This fix therefore avoids creating PathTraceWork for dummy devices
and checks for device creation errors earlier in the process.
JIT compilation of oneAPI kernels now happens during load stage
and proper message gets shown in the GUI during compilation.
Also, this implementation skips kernels that aren't needed for
the used scene, reducing overall (re)compilation time.
X11 is used as a fallback when libdecor isn't found on the users system.
Now print a warning when Blender falls back to X11 and a missing
libdecor is the only reason wayland could not be used.
Only print this warning when using Wayland so this warning doesn't show
on X11 systems which have Wayland libraries installed.
Addresses T101715.
Show the windowing environment on non MS-Windows/Apple systems,
since X11/WAYLAND are selected startup there was no convenient way
for users to know which back-end was being used.
Include the windowing environment in the About splash & system-info.txt
since it will be useful for handling bug reports.
This commit adds a private API call not intended for general use
as I would like to be able to remove this later and it's only needed
in the specific case of testing if Blender is using WAYLAND or X11
(which maybe be used via XWayland).
Python scripts can already inspect the system to check which windowing
environment used, the API call is mainly useful for troubleshooting.
OSL (like Cycles) has no internal boolean type, instead an integer
input can be flagged to be shown as a boolean in the UI.
Cycles reacts to this by creating a boolean socket on the Blender
side, but as a result incorrectly called the boolean overload of the
set function even though the internal type is an integer.
There's another unrelated crash in the GPU viewport shader code that
appears to apply to every OSL node that outputs a shader, and the file
in T101702 triggers both, so this is only a partial fix for the report.
The attribute node already allows accessing attributes associated
with objects and meshes, which allows changing the behavior of the
same material between different objects or instances. The same idea
can be extended to an even more global level of layers and scenes.
Currently view layers provide an option to replace all materials
with a different one. However, since the same material will be applied
to all objects in the layer, varying the behavior between layers while
preserving distinct materials requires duplicating objects.
Providing access to properties of layers and scenes via the attribute
node enables making materials with built-in switches or settings that
can be controlled globally at the view layer level. This is probably
most useful for complex NPR shading and compositing. Like with objects,
the node can also access built-in scene properties, like render resolution
or FOV of the active camera. Lookup is also attempted in World, similar
to how the Object mode checks the Mesh datablock.
In Cycles this mode is implemented by replacing the attribute node with
the attribute value during sync, allowing constant folding to take the
values into account. This means however that materials that use this
feature have to be re-synced upon any changes to scene, world or camera.
The Eevee version uses a new uniform buffer containing a sorted array
mapping name hashes to values, with binary search lookup. The array
is limited to 512 entries, which is effectively limitless even
considering it is shared by all materials in the scene; it is also
just 16KB of memory so no point trying to optimize further.
The buffer has to be rebuilt when new attributes are detected in a
material, so the draw engine keeps a table of recently seen attribute
names to minimize the chance of extra rebuilds mid-draw.

It fixes SYCL runtime issues in Debug builds that were due to mixing
Release and Debug MSVC runtimes.
This commit also removes specific handling of dpcpp compiler executable
to simplify the CMake implementation. Using it like clang++ works and
clang++ executable is also available from Intel oneAPI DPC++ compiler in
case it doesn't.
This is a minimal set of changes, allowing a lot of cleanup that can
happen afterward as it allows sycl method and objects to be used outside
of kernel.cpp.

GNOME (mutter) intentionally doesn't follow the Wayland spec for the
keyboard_enter events (held keys are always an empty array).
This means we can't know which keys are held on window activation,
making the result of getModifierKeys invalid (in that we don't know
which modifiers are held).
Detect this situation and suppress warnings as the issue has been
reported and it doesn't help for users to see noisy warnings for
a known problem.
Changing volume parameters during rendering could cause a crash
when guiding was enabled. It was due to an unintialized state paramter
at the beginning of the path tracing process.
In addition guiding is disabled when dealing with almost delta volumes
(i.e., g close to 1.0 or -1.0).
The code already had a check for meshes with zero triangles, but it
didn't catch the case where all triangles are flagged as degenerate.
A simple way to reproduce this is to take a mesh and scale it to zero.
After checking the code, it turns out that in this case it's supposed
to just set all tangents to zero, so the fix simply is to detect this
case and skip the computation.
To avoid issues with install_deps. If we more generally switch to using
CMake configs then perhaps this code can be deduplicated again or at
least simplified.
This change speeds up the compilation at the cost of higher memory usage.
CMake implementation checks the amount of available memory to spawn a
reasonable number of parallel compiler jobs.
Rename BKE_appdir_folder_id_version to
BKE_appdir_resource_path_id_with_version because BKE_appdir_folder_id
and BKE_appdir_folder_id_version didn't accept compatible arguments.
Also add notes to GHOST_getSystemDir & GHOST_getUserDir that
BKE_appdir_resource_path_id(..) should be used instead (in most cases).
Previously it would bake viewed from above the surface. The new option can be
useful when the baked result is meant to be viewed from a fixed viewpoint or
with limited camera motion.
Some effort is made to give a continuous reflection on parts of the surface
invisible to the camera, but this is necessarily only a rough approximation.
