Enable the Vulkan backend when building Dawn with
the Chromium build system for Fuchsia. To make this
work properly the following is required:
- Modify VulkanInfo.cpp and BackendVk.cpp to correctly probe
the Fuchsia swapchain layer and its layer extension, as well
as enabling them when creating a new VkInstance.
- Modify VulkanFunctions.cpp to load the Fuchsia swapchain
related extension for this platform only.
- Provide a small mock GLFW library for Fuchsia under
src/utils/Glfw3Fuchsia.cpp, since the upstream project
does not support this platform at all. Its purpose is
only to allow the creation of the right VulkanBinding
instance, which depends on the creation of a display
surface for latter swapchain creation.
- Add //third_party/fuchsia-sdk:vulkan_base and
//third_party/fuchsia-sdk:vulkan_validation as
data_deps of the libdawn_native_sources target in
order to ensure that the Fuchsia package created by
the build system will include the correct Vulkan
libraries (loader and validation layers).
This builds correctly, and both dawn_unittests and
dawn_end2end_tests will run on a real Fuchsia device
or inside the Fuchsia emulator, using either GPU
virtualization or a software-based renderer.
Note: dawn_unittests will also run inside QEMU, but
not dawn_end2end_tests, since the latter requires
proper GPU emulation which is not available in this
environment.
NOTE: All end2end tests pass using a device with
an "Intel HD Graphics 615 (Kaby Lake GT2)"
adapter. However:
- For some reason, a single test takes up
to 129 seconds to pass
(BufferSetSubDataTests.ManySetSubData/Vulkan).
- The test process crashes inside VkDestroyInstance(),
apparently inside the Fuchsia-specific imagepipe
layer (which implements swapchain support).
This is likely a bug in the layer itself, and
not Dawn.
Also, may end2end tests will crash when run inside
the Fuchsia emulator (which uses GPU virtualization
to talk to the host GPU). The crashes happen inside
libvulkan-goldfish.so, the emulator-specific Vulkan
ICD on this sytem. Not a Dawn bug either.

As part of enabling WebGPU on Chrome OS, we would like to run the Dawn

the GLFW dependency because Chrome OS does not support GLFW.
The GLFWwindow is only used to create swap chains for the various
backends, but these swap chains are not actually used in the tests
(the e2e tests render to textures instead). The swap chains are only
referenced as part of an unused debugging function:
SwapBuffersForCapture which we can safely remove as per my discussions
with kainino@ and enga@.
We still need GLFW for OpenGL, so we conditionally include it on
platforms that enable the OpenGL backend (which Chrome OS is not).
Note: enga@ suggested to create a VulkanWindowlessBinding that has an
empty GetSwapChainImplementation, but after exploring the option, it
seems like a bit too many ifdefs. In the end, I think it's cleaner to
just remove the *Binding classes entirely.

Metal uses a physical addressing mode and buffers are just pointers in
GPU memory that don't have a size. This prevents implementing
OpArrayLength without any additional information. When a shader uses
OpArrayLength on unsized arrays, SPIRV-Cross requires an extra buffer
argument that gets the length of the buffers.
Use that workaround mechanism in the Metal backend by keeping track of
the storage buffer sizes and applying the extra "buffer length buffer"
when a pipeline requires it.
Also adds tests that OpArraySize works in all shader stages.

This is needed for two reasons:
- TextureBase and TextureViewBase stored Formats by value which isn't too
much overhead at this time but will get bigger in the future.
- The OpenGL backends needs its own GLFormat structure to store data about
each format which will eventually contain complicated logic to detect
support in the GL driver so it shouldn't be duplicated in Textures.
The computations of the information about Format is moved from being done
whenever they are needed to being precomputed at DeviceBase initialization.
This makes each format have a constant "index" in that can be used in the
backends to address their own structure, for example a GLFormat table.
Also some DeviceBase pointers were made const for validation.

Ensure that //src/common exports the appropriate config settings

at once:
- A target that depends on //src/common and wants to find
"common/vulkan_platform.h" needs to have "${dawn_root}/src"
in its include_dir.
- Same target needs to have DAWN_ENABLE_VULKAN macro to avoid
a compile #error message when including "common/vulkan_platform.h"
- Same target needs to be able to find <vulkan/vulkan.h> which
is included by "common/vulkan_platform.h".
This is achieved by ensuring that the "dawn_internal" config,
is provided as a public_config by the GN ":common" target.
And by adding third_party/vulkan_headers as a public_deps
if |dawn_enable_vulkan| is true.
Note that "dawn_internal" is used by several other targets
in Dawn BUILD.gn files, hence why it was not renamed to something
else like "dawn_common_config" here.
+ Simplify targets that currently depend on ":common" so they
no longer need to add vulkan_headers as an explicit dependency.

This patch supports BC5 formats on Vulkan backends and adds related
Dawn end2end tests.
For the textures with BC formats, they could have non-multiple-of-4
sizes on the non-zero mipmap levels in sampling, but we are still
required to provide texture data in complete 4x4 blocks in texture
copies because that is the size of which they are stored in GPU memory.
In this patch, we refer the term "physical memory size" as the memory
size of the texture subresource in GPU memory, and the term "virtual
memory size" as the size used in texture sampling. As Dawn requires
the Extent3D in texture copies must fit in the physical memory size,
while Vulkan requires it must fit in the virtual memory size, this
patch recalculates the imageExtent to ensure it always follow this
Vulkan validation rules.
For Dawn end2end tests, note that we use pure green and pure red for
the textures because BC5 does not support SRGB formats. Furthermore,
"CopyPartofTextureSubResourceIntoNonZeroMipmapLevel" is skipped in
this patch because there is an issue on the T2T copies from a region
within the virtual size of one texture to another one that exceeds

required in Vulkan (and RG8UnormSrgb is in fact not supported on the

repo to remove the from the initial list of formats.
The RG11B10Float and RGB10A2Unorm formats of WebGPU are replaced with
B10GR11Float and A2RGB10Unorm that are the formats exposed by Vulkan. It
is likely that all APIs implement them with components stored in that
order.
Each format except depth-stencil ones is tested by uploading some
interesting texel data and checking that sampling from the texture
produces correct results. The goal is to make sure that backends don't
make a mistake in the giant switch statements. There was no effort made
to check the hardware implementation of the formats.
Tests will later be extended to cover rendering and clearing operations
as well as multisample resolve.
It isn't clear if depth-stencil format will support TRANSFER operations
in WebGPU so these are left untested for now.

This move all the OpenGL-specific code for swapchain handling in a new
NativeSwapChainImpl in the OpenGL backend so no code outside of
dawn_native needs OpenGL.

This makes the OpenGL entry points loaded at Adapter creation from the
getProcAddress passed in the DiscoveryOptions and update all GL calls in
the backend to go through the new OpenGLFunctions object.
A code generator is added that generates the function loader and list of
GL procs from Khronos' gl.xml file but we can't get rid of glad yet
because it is used to have the PROC typedefs and enum values.

This prevents dirty textures to be used when memory is recycled
while destroying/creating textures. If a texture is not cleared at load,
it will be cleared to 0 before it is used.

This merges all the files for main.py together again except
generator_lib.py because there doesn't seeem to be a good way to
separate the pure dawn.json generators and the dawn wire generator.
Also updates the GN templates to make it easier to define new generators
based on generator_lib, and move the Jinja2 template "stdlib" to
generator_lib.py
