Looks like OSX changed the default format of its locale, which is not
valid anymore for gettext/boost::locale.
Solution based on investigations and patch by Kieun Mun (@kieuns), with
some further tweaks by Ankit Meel (@ankitm), many thanks.
Also add an exception catcher on `std::runtime_error` in
`bl_locale_set()`, since in OSX catching the ancestor `std::exception`
does not work with `boost::locale::conv::conversion_error` and the like
for some reasons.

Just disable these tests on macOS for now as fixing seems hard, and we want to
be able to cross-compile and test x86_64 on Arm machines on the buildbot.

This is required for Cycles to report a meaningful error message when it fails to load a PTX module
created with a newer CUDA toolkit version than the driver supports.

This fixes a performance regression on Ampere cards, on specific scenes like
classroom. For cycles-x there is little difference, but this is still helpful
for LTS releases, and we need to upgrade at some point anyway.

Something in this update broke the floor() function in CUDA, instead use
floorf() like we do everywhere else in the kernel code. Thanks to Ray
Molenkamp for identifying the solution.

With this patch the build system checks whether the "CUDA10_NVCC_EXECUTABLE" CMake
variable is set and if so will use that to build sm_30 kernels. Similarily for sm_8x kernels it
checks "CUDA11_NVCC_EXECUTABLE". All other kernels are built using the default CUDA
toolkit. This makes it possible to use either the CUDA 10 or CUDA 11 toolkit by default and
only selectively use the other for the kernels where its a hard requirement.

Running Blender on Ampere cards was already possible with ptx, this fix is
needed to support building CUDA binaries.
Note the CUDA version used for official Blender builds is still 10, this is
merely the change to make it possible for those using CUDA 11 and specifying
the sm_8x kernels to be compiled.

The OptiX kernels are compiled for target "compute_sm_52", which is only available on second
generation Maxwell GPUs, so disable support for older ones.

This patch changes the discovery of pre-compiled kernels, to look for any PTX, even if
it does not match the current architecture version exactly. It works because the driver can
JIT-compile PTX generated for architectures less than or equal to the current one.
This e.g. makes it possible to render on a new GPU architecture even if no pre-compiled
binary kernel was distributed for it as part of the Blender installation.

On user level this fixes dead-lock of OpenCL render on Intel Iris GPUs.
Note that this patch does not include change in the logic which allows
or disallows OpenCL platforms to be used, that will happen after the
kernel fix is known to be fine for the currently officially supported
platforms.
The dead-lock was caused by wrong usage of memory barriers: as per the
OpenCL specification the barrier is to be executed by the entire work
group. This means, that the following code is invalid:
void foo() {
if (some_condition) {
return;
}
barrier(CLK_LOCAL_MEM_FENCE);
}
void bar() {
foo();
}
The Cycles code was mentioning this as an invalid code on CPU, while in
fact this is invalid as per specification. From the implementation side
this change removes the ifdefs around the CPU-only barrier logic, and
is implementing similar logic in the shader setup kernel.
Tested on NUC8i7HVK NUC.
The root cause of the dead-lock was identified by Max Dmitrichenko.
There is no measurable difference in performance of currently supported
OpenCL platforms.

In scenes such as Cosmos Laundromat, there were memory allocations bigger than
2GB which would overflow.
Problem and solution found by AMD, thanks!

When Blender is started in fullscreen mode from the command line,
or if the fullscreen state is saved in the startup file, all temporary windows
will also open in fullscreen mode. When closing the fullscreen File Browser,
Blender would either crash or parent window becomes black.
This does not happen if the Blender switches to full screen manually.
`NSWindowCollectionBehaviorFullScreenPrimary` should be set for windows that
can enter full-screen mode. Otherwise macOS will turn the wrong window into
full-screen.

Steam just released a SteamVR update with OpenXR Developer Preview
support:
https://steamcommunity.com/games/250820/announcements/detail/2396425843528787270.
Once SteamVR is set up for OpenXR (see link above), it works with
Blender "out of the box", thanks to OpenXR!
We have to apply the sRGB transform workaround for SteamVR though,
otherwise it renders way too dark. Done in the next commit.
Note that AMD users may still only see a pink screen, because the
OpenGL-DirectX compatibility fails. I will check on a fix again.
For SteamVR on Linux we may have to wait for until it supports OpenGL
rendering for OpenXR. Alternatively, we *could* add initial Vulkan
support at Ghost level and use Vulkan<->OpenGL interoperability
extensions, Monado uses these as well.

Caused by c7aa0f9d743ee9cafe91b4a51d9f1ecc5e437d71.
Since above commit, BKE_image_user_frame_calc requires an image (not
just the iuser) to get the framenumber.
Cycles used to call this with NULL image (in `image_user_file_path` and
`image_user_frame_number`), now pass the image as well.

Windows only workaround. I'll have to investigate Linux separately.
Steam's OpenGL compatibility is still new and doesn't work for us yet
(neither does it for standard OpenXR examples from what I've heard and
seen myself). We can work around that by falling back to our DirectX
compatibility layer.
Note that this DirectX compatibility still doesn't work for some
systems, see T76082.
Implementation note: Since the graphics binding extensions have to be
enabled before we can find out which runtime is in use (e.g. SteamVR vs.
Oculus, etc), we can now enable multiple graphics binding extensions but
settle for a single one to use later.
Once the SteamVR OpenGL backend works, we can remove this workaround
again.
Fixes T78267.

Latest SteamVR OpenXR updates brought OpenGL support, but only with sRGB
buffers. I think for DirectX it's the same now.
It's not a big issue for us to use sRGB buffers, so that's what I will
do for now. That way we shouldn't need hardcoded exceptions for specific
runtimes that don't transform linear buffers correctly.

Fix several issues in CLOG code:
* In `clg_str_reserve`, allocated memory may be bigger than requested
one, do not assign the latter back to `cstr->len_alloc`.
* `clg_str_vappendf` was mis-interpreting returned value from
`vsnprintf`, and completely mixing total allocated memory and extra
needed amount of memory to allocate...
Simplified code of `clg_str_vappendf` to only have allocating code
handled in one place, makes things easier to follow too.
Think this should also be beckported to 2.83.

Apply the workaround only for known problematic drivers. The latest pro driver
appears to work correctly, hopefully the regular driver will as well once it
is updated to the same OpenCL driver version (3075.13).

Don't access evaluated mesh data after freeing Blender depsgraph.
Potentially related to T77954.
|

The code to implement the newer closure in terms of the old one got lost in
the removal of our stdosl.h copy. Now implement it as a builtin closure.
|
|
Since the sampling and evaluation functions handle both cases anyways,
there's not really a point for keeping the distinction in the kernel,
so we might as well cut down the number of CLOSURE_BSDF_MICROFACETs a bit.

When closing the File Browser window after making it fullscreen, Blender would
either crash or all windows would disappear, with no obvious way to bring them
back.
The "fix" is to not allow fullscreen for File Browsers (or any future "dialog"
windows), but only maximizing. From what I can tell that's how secondary
windows are supposed to work on macOS. What we previously did seemed like
something macOS doesn't handle cleanly, and I didn't find a simple way to do so
on our side.

The input data to the OptiX denoiser was clamped to 0..10000 as required, but it could easily
exceed that range with a high number of samples (since the data contains the overall sum). To
fix that, divide by the number of samples first and multiply it back in after the denoiser ran.

The problem was that Cycles would store a pointer to an object in
`DEGObjectIterData->templ_dupli_object`. This pointer was then accessed
when the iterator was already freed.
