+OpenVR SDK
+---
+
+OpenVR is an API and runtime that allows access to VR hardware from multiple
+vendors without requiring that applications have specific knowledge of the
+hardware they are targeting. This repository is an SDK that contains the API
+and samples. The runtime is under SteamVR in Tools on Steam.
+
+### Documentation
+
+Documentation for the API is available on the [Github Wiki](https://github.com/ValveSoftware/openvr/wiki/API-Documentation)
+
+More information on OpenVR and SteamVR can be found on http://steamvr.com

+This directory contains files from the OpenVR SDK, version 1.11.11.
+
+This SDK contains the OpenVR API interface headers and functions to load the
+OpenVR runtime libraries which actually implement the functionality. The
+loading functions parse a .json file in a pre-defined location on the
+end-user's machine to get details used to bind the correct runtime library.
+The OpenVR implementation ensures forward and backwards compatibility as of
+the current version.
+
+Updated versions of the OpenVR SDK are available on Github:
+
+https://github.com/ValveSoftware/openvr
+
+
+We only use some files from the SDK:
+
+- We strip out files such as C# headers, plain C API versions, and files
+ needed only when implementing OpenVR drivers.
+
+- CMake related files, such as CMakeLists.txt are skipped as we use moz.build
+ files to configure the library.
+
+- The "src/jsoncpp.cpp" file and the "src/json" directory can be skipped. OpenVR
+ uses the jsoncpp library, which we have already imported elsewhere. If
+ warnings about using deprecated jsoncpp classes show up during compilation
+ you might need to reapply the patch in bug 1598288. It replaces uses of the
+ `Json::Reader` and `Json::StyledWriter` classes with the more modern
+ `Json::CharReaderBuilder` and `Json::StreamWriterBuilder`.
+
+
+Steps to update the library:
+
+- Copy "README.md" from the root of the openvr repo to the "gfx/vr/service/openvr"
+ directory.
+
+- Copy "headers/openvr.h" to "gfx/vr/service/openvr/headers" directory. The other files
+ in this directory can be ignored.
+
+- The rest of the files in the "src" directory and the "src/vrcommon" are copied
+ to the "gfx/vr/service/openvr/src" directory.
+
+- Update "gfx/vr/service/openvr/moz.build" when files are added or removed.
+
+- Update the "strtools_public.h" and "strtools_public.cpp" files, commenting out
+ the "Uint64ToString", "wcsncpy_s", and "strncpy_s" functions.
+ The "Uint64ToString" function name conflicts with another used in Gecko and
+ the "errno_t" return type returned by the other functions is not defined in
+ Mozilla's macOS continuous integration build environments. Fortunately, the
+ OpenVR SDK does not use these functions.
+
+- Replace the #define VR_INTERFACE in openvr.h to avoid extern'ing the functions.
+ Unlike the usual OpenVR API builds, we are not building a separate dll.
+
+- Add explicit in CVRSettingHelper constructor.
+
+- In strtools_public.cpp/.h, ensure that UTF16to8 and UTF8to16 are only
+ compiled under
+ #if defined( _WIN32 )
+ and redefine those functions to use ::WideCharToMultiByte and
+ MultiByteToWideChar, respectively. These are modified because the original
+ implementations contain unsupported try-catch.
+
+- In strtools_public.cpp, remove the definition of convert_type.
+
+- In strtools_public.cpp, remove the include of <codecvt>, as this causes
+ problems in compiling on Linux.
+
+- In pathtools_public.cpp/.h, comment out Path_UrlToFilePath and
+ Path_FilePathToUrl to avoid a compile error because 'alloca' isn't defined.
+
+- In vrpathregistry_public.cpp, CVRPathRegistry_Public::BLoadFromFile contains
+ a try-catch, which is not permitted. This code is simply commented out, but
+ Bug 1640068 - OpenVR code can fail JSON parsing and raise exceptions
+ is filed to address a safe fallback in the error condition.
+
+- Update this README.mozilla file with the new OpenVR SDK version and any
+ additional steps needed for newer versions.
+
+- Ensure that any changes made within the OpenVR files have comments including
+ the string "Mozilla" and reference this file for easy identification.

+This is the source code for the OpenVR API client binding library which connects
+OpenVR applications to the SteamVR runtime, taking into account the version
+of the OpenVR interface they were compiled against.
+
+The client binding library - openvr_api.dll on Windows, openvr_api.so on
+Linux, and openvr_api.dylib or OpenVR.framework on macOS - knows how to find
+and read the SteamVR runtime installation information which allows it to
+find and dynamically connect to the installed runtime. In combination with the
+interface version identifiers from /include/openvr.h which are baked
+into applications at the time they are built, the OpenVR API client
+binding library captures and conveys to the SteamVR runtime the version
+of the OpenVR API interface behavior that the application expects.
+
+Applications carry with them a private/local copy of the client binding
+library when they ship, and they should install it locally to their
+application. Applications should not install the client binding library
+globally or attempt to link to a globally installed client binding library.
+Doing so negates at least part of the ability for the client binding library
+to accurately reflect the version of the OpenVR API that the application
+was built against, and so hinders compatibility support in the face of
+API changes.
+
+Most applications should simply link to and redistribute with their application
+the pre-built client binding library found in the /bin directory of this
+repository. Some small number of applications which have specific requirements
+around redistributing only binaries they build themselves should build
+the client library from this source and either statically link it into
+their application or redistribute the binary they build.
+
+This is a cmake project, to build it use the version of cmake appropriate
+for your platform. For example, to build on a POSIX system simply perform
+
+ cd src; mkdir _build; cd _build; cmake ..; make
+
+and you will end up with the static library /src/bin/<arch>/libopenvr_api.a
+
+To build a shared library, pass -DBUILD_SHARED=1 to cmake.
+To build as a framework on apple platforms, pass -DBUILD_FRAMEWORK=1 to cmake.
+To see a complete list of configurable build options, use `cmake -LAH`
