Austin Eng f35dcfe60a Implement ErrorScopes for synchronous errors
This patch implements Push/PopErrorScope except for asynchronous
or GPU commands. These commands, such as Queue::Submit will need
to hold onto the ErrorScope until GPU execution is complete.

David 'Digit' Turner fa00c69506 [fuchsia] Implement external semaphore and memory support.
This CL adds Fuchsia-specific implementations to the following
classes:

  dawn_native::vulkan::external_memory::Service
  dawn_native::vulkan::external_semaphore::Service

The implementation is based on two Fuchsia Vulkan extensions
that are provides by the vulkan_fuchsia_extras.h header (i.e.
are not upstreamed to Khronos yet, but used/provided by the
Fuchsia platform):

  VK_FUCHSIA_external_memory
  VK_FUCHSIA_external_semaphore

Their details are similar to VK_KHR_external_XXXX_fd, but
uses Zircon handles instead of file decriptors.

David 'Digit' Turner b749d07ac9 Enable Vulkan for Chromium Fuchsia build.
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.

Brian Ho 2fb628da46 Remove GLFW dependency for non-GL tests
As part of enabling WebGPU on Chrome OS, we would like to run the Dawn
unit and e2e tests as part of the Chrome OS test suite. This CL removes
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.

Corentin Wallez bfc9cee5d3 Implement OpArrayLength on Metal
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.

 - 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.

David 'Digit' Turner 56a21a6151 Make GN //src/common target easier to use when Vulkan is enabled.
Ensure that //src/common exports the appropriate config settings
when vulkan is enabled. This CL tries to address several issues
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.

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
the virtual size of another texture in Vulkan SPEC.

Corentin Wallez 431d618961 Add most WebGPU texture formats on Vulkan
This adds the formats to dawn.json, implements support in the Vulkan
backend and adds tests performing basic sampling checks for all formats.

The R8UnormSrgb and RG8UnormSrgb formats skipped because they are not
required in Vulkan (and RG8UnormSrgb is in fact not supported on the
machine used for developing this CL). A PR will be sent to the WebGPU
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.

Yan, Shaobo 34f2fe8a52 Dynamic Buffer Offset : Metal Backend
In a typical application, most draws will use different uniforms values for
things like the world position and orientation. In the current state of WebGPU
this means that a new bind group needs to be created for each draw to set the
right uniforms. Bind group creation is expected to be more expensive than
recording draws because they incur an allocation.

This feature is to reduce the number of bind groups that need to be
created.

The patch implemented dynamic buffer offset on metal backend.

Jiawei Shao 15d4c2e63b Emulate store and multisample resolve on Metal
This patch implements "store and MSAA resolve" store operation on Metal
drivers that don't support MTLStoreActionStoreAndMultisampleResolve with
a workaround that does MSAA resolve in another render pass.

Driver workaround is one type of Dawn Toggles. Dawn Toggles will include
other optional optimizations and features that can be configured to use
or not when we create Dawn Devices.

As all Metal try bots don't need this toggle, to better test this
patch on the try bots:
1. We add the support of forcing enabling a workaround when starting an
   Dawn end2end test so that we can test the workaround on the platforms
   where the workaround is disabled.
2. We add an optional parameter DeviceDescriptor to CreateDevice() so
   that we can custom the toggles the Dawn device should use.

This patch also adds the support of querying toggle details from Instance
and the names of the toggles in use from Device. These APIs are tested in
the Dawn unittests added in this patch.

fix.

This patch also fix a bug when clearing depth stencil attachments on

enable depth stencil writing by properly setting depth and stencil
masks. We do not need to set the depth and stencil masks back because
they will be set again when applying the render pipeline. The newly

Reason for revert:
Fixed test failure by submitting basic render pass to clear out texture
before running the tests.

The test was failing previously because the texture pixel color was not
cleared before running the tests, causing unexpected
pixel colors to be compared. Creating a basic render pass clears
the texture, but since the first test fails on submit expectedly,
the pixel is never cleared.

The *_export.h files are modified to noop when *_SHARED_LIBRARY is not

A dawn_library_combo is introduced in BUILD.gn that factors out all the
logic needed to produce shared libraries and handle the _EXPORT macros.

Also contains a fix to dawncpp to export only the methods that aren't

New objects are introduced to control what happens before device

 - Instance: a connection from the application to dawn_native that is
used for dependency injection and to discover adapters.
 - Adapters: represents the possibility of device creation for a specific
(GPU, backend) pair.
 - BackendConnection: an internal object that standardizes the interface
between the frontend and backends.

The BackendConnection interface is implemented for the Null backend and
stubbed out in other backends. This allows this change to port the
ValidationTests to use the new Instance and Adapters concept and deal

Ryan Harrison 9854295ff6 Add fuzzers for SPIRV-Cross
This CL adds in fuzzers for SPIRV-Cross for HLSL, GLSL, and MSL
outputs. These fuzzers live in Dawn because there is not appropriate
location in the Chromium source repo for them and it is unlikely they
would be land-able in the SPIRV-Cross repo, because it is not coupled
with Chromium's build system and thus Clusterfuzz so would be
effectively dead code. Dawn depends on this code, but it is also
integrated into the Chromium build system, so this was the best place
I could find for them

The code under fuzz unfortunately uses exceptions/aborting as its
error reporting mechanism. This is an acknowledge short coming and
there are efforts to remove this behaviour. To work around this and
reduce the number of false positives found by the fuzzers, a signal
trap has been implemented which will be removed once the code under
fuzz has been updated.

The trap replaces the existing signal handler and silencing signals
while running the code under test. This allows the code under test to
call abort() and not crash the fuzzing process. Theoretically, only
SIGABRT should need to be trapped, but something is causing the signal
from abort() to be converted to SIGSEGV when running under ASAN.

This signal trap has been tested with the fuzzing/sanitizers by
intentionally inserting bad calls that will occur after a few thousand
test cases. It was confirmed that the fuzzer detected the issue and
stops fuzzing.

The alternate to implementing this signal trap would be to turn on
exceptions for the fuzzer. This was attempted, but proved to be
fruitless due to what was reported as an ODR issue, but couldn't
couldn't be silenced. The likely underlying issue was a pre-built
library or other object being built without exceptions was causing
different versions of symbols or the exception version of the standard
library not being instrumented by ASAN. Given the majority of Chromium
eco-system turns off exceptions, fixing this issue would not be
helpful to the larger community and was looking like it would require
significant effort.

Corentin Wallez 82fbccbd78 Introduce [Render|Compute]PassEncoder.
This splits off part of CommandBufferBuilder in separate
RenderPassEncoder and ComputePassEncoder objects. To match the WebGPU
IDL and factor some code, both these encoders inherit from
ProgrammablePassEncoder.

These encoders are pure frontend objects and record into the
CommandBufferBuilder command allocator objects, so no changes to the
backends were needed.

Error handling is still ew, because the "builder" mechanism we had
doesn't allow for "split builders". Nicer error handling will have to
wait on Dawn matching WebGPU.

All the tests and samples were updated to the new structure.

d3d12.dll. Instead we dynamically load functions pointers from these
DLLs at d3d12::Device startup.

Corentin Wallez 59e7fad99b BUILD.gn: Remove use of exec_script
Chromium's BUILD files try to avoid uses of exec_script when possible
because they slow down every GN invocation. In preparation for building
Dawn inside Chromium, the calls to exec_script for the code generator
are removed.

In GN, the generator now outputs a "JSON tarball", a dictionnary mapping
filenames to content. This allows us to use the "depfile" feature of GN
to avoid the exec_script call to gather the script's inputs.

Outputs of the generator are now listed in the BUILD.gn files. To keep
it in sync with the generator, GN outputs a file containing "expected
outputs" that is checked by the code generator.

Finally the dawn_generator GN template doesn't create a target anymore,
but users are expected to gather outputs using get_target_outputs.

Corentin Wallez 5b61abce09 Fix Windows compilation using GN and clang-cl.
This includes a bunch of fixes for clang warnings in Windows specific
code that was only compiled by MSVC previously. This also tidies up some
BUILD.gn issues on Windows.

Corentin Wallez 3bb0bb940e Generator,BUILD.gn: add optional python path, use it for Jinja2
This makes the Jinja2 (and MarkupSafe) installation hermetic by
adding it to the DEPS and making the code generator add them in the
first spot of the python path.

Corentin Wallez d2969a7d3d Make Dawn "gn check" by default (except SPIRV-Tools)
This required adding some missing dependencies, splitting public headers
of libdawn_[native|wire] so they aren't hidden in the
libdawn_[native|wire]_sources targets, and making unittests depend on
sources directly instead of static libraries (which is almost equivalent).

As a byproduct, Empty.cpp is no longer needed and is removed.

Corentin Wallez c0494762b7 Speed up the code generator for exec_script.
The code generator doesn't need to load the JSON file to compute the
dependencies our outputs for a codegen target. To better integrate in
noop builds, the lazy-write of generated file is removed because it led
to the code generator running even in noop build (the timestamp of
generated file not being updated).

Also document what could be done to avoid exec_script calls for the Dawn
code generator.
