Roll third_party/dawn/ (1684 commits) and clean up WGPU_BREAKING_CHANGEs With this roll, Dawn has completed the WGPU_BREAKING_CHANGE_* changes, so the old paths are no longer used. The roll: https://dawn.googlesource.com/dawn.git/+log/7a8946456d49..d85fc050fef7 Created with: roll-dep third_party/dawn Bug: chromium:427242889 Change-Id: Ia17fbc1447944e7bcea20d5004367d94cf7be10e Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/6729918 Commit-Queue: Geoff Lang <geofflang@chromium.org> Auto-Submit: Kai Ninomiya <kainino@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org>
This folder contains shared back-end-specific implementation files. The classes
and types in renderer are not specified by GLES. They instead are common to
all the various ANGLE implementations.
See renderer_utils.h for various cross back-end utilties.
The ANGLE format class, angle::Format, works as a union
between GLES and all the various back-end formats. It can represent any type
of format in ANGLE. e.g. Formats in Vulkan that don’t exist in GLES, or DXGI
formats that don’t exist in GLES, or Windows/Android surface configs that
don’t exist anywhere else.
The glInternalFormat member of angle::Format represents the “closest” GL
format for an ANGLE format. For formats that don’t exist in GLES this will
not be exactly what the format represents.
The back-ends also define their own format tables. See the Vulkan Format table docs and the [D3D11 format table docs][D23D11FormatDocs].
DXGI formats are used in both the GL and D3D11 back-end. Therefore the generated info table lives in this common shared location.
The DXGI info table is generated by gen_dxgi_format_table.py
and sources data from dxgi_format_data.json. The
main purpose of the table is to convert from a DXGI format to an ANGLE
format, where the ANGLE format should have all the necessary information.
