This subdirectory contains Android's Vulkan loader, as well as some Vulkan-related tools useful to platform developers.
We follow the Chromium coding style for naming and formatting, except with four-space indentation instead of two spaces. In general, any C++ features supported by the prebuilt platform toolchain are allowed.
Use "clang-format -style=file" to format all C/C++ code, except code imported verbatim from elsewhere. Setting up git-clang-format in your environment is recommended.
We generate several parts of the loader and tools from a Vulkan API description file, stored in api/vulkan.api
. Code generation must be done manually because the generator tools aren't part of the platform toolchain (yet?). Files named foo_gen.*
are generated from the API file and a template file named foo.tmpl
.
To run the generator:
$HOME/lib/go
) for local go sources and binaries and add it to $GOPATH
.$ git clone https://android.googlesource.com/platform/tools/gpu $GOPATH/src/android.googlesource.com/platform/tools/gpu
$ go get android.googlesource.com/platform/tools/gpu/api/...
$GOPATH/bin/apic
. You might want to add $GOPATH/bin
to your $PATH
.To generate libvulkan/dispatch_gen.*
,
$ cd libvulkan
$ apic template ../api/vulkan.api dispatch.tmpl
Similar for nulldrv/null_driver_gen.*
