Monado 0.2 (2020-05-29)

• Major changes
  • Add support for a new service process. This process houses the hardware drivers and compositor. In order to do this, a whole new subsection of Monado called ipc was added. It lives in src/xrt/ipc and sits between the state trackers and the service hosting the drivers and compositor. (!295)
  • Support optional systemd socket-activation: if not disabled at configure time, monado-service can be launched by systemd as a service with an associated socket. If the service is launched this way, it will use the systemd-created domain socket instead of creating its own. (If launched manually, it will still create its own as normal.) This allows optional auto-launching of the service when running a client (OpenXR) application. Associated systemd unit files are also included. (!306)
• XRT Interface
  • Add a new settings interface for transporting camera settings, in xrt/xrt_settings.h. (!266)
  • Make it possible to send JSON object to drivers when probing for devices. (!266)
  • Added new xrt_instance object to be root object, a singleton that allows us to better swap out the whole stack underneath the state trackers. This is now implemented by the xrt_prober code and used by the OpenXR state tracker. (!274)
  • Remove the struct timestate argument from the struct xrt_device interface. It should be easy to write a driver and the state tracker should be the one that tracks this state. It was mostly triggered by the out of process compositor work. (!280)
  • Add the new format XRT_FORMAT_UYVY422 to the interface and various parts of the code where it is needed to be supported, like the conversion functions and calibration code. Also rename the XRT_FORMAT_YUV422 to XRT_FORMAT_YUYV422. (!283)
  • Expose manufacturer and serial number in the prober interface, right now only for the video device probing. But this is the only thing that really requires this in order to tell different cameras apart. (!286)
  • Add XRT_CAST_PTR_TO_OXR_HANDLE and XRT_CAST_OXR_HANDLE_TO_PTR macros to perform warning-free conversion between pointers and OpenXR handles, even on 32-bit platforms. They should be used instead of raw casts. (!294)
  • Remove declaration and implementations of xrt_prober_create: the minimal functionality previously performed there should now be moved to xrt_instance_create. (!347)
• State Trackers
  • gui: Fix compilation issue in st/gui when building without OpenCV. (#63, !256)
  • OpenXR: Don't return struct with invalid type from xrEnumerateViewConfigurationViews. (!234)
  • prober: Print more information from the prober when spewing. (!261)
  • gui: Save camera and calibration data using new settings structs and format. (!266)
  • prober: Load tracking config from json and use new settings struct. (!266)
  • gui: Fix name not being shown when video device does not have any modes. (!269)
  • gui: Remove old video test scene, never used and seemed to be broken. (!275)
  • gui: Fix build when OpenCV is not available or disabled. (!292)
  • OpenXR: Fix build when OpenGL is not enabled. (!292)
  • OpenXR: Validate that we support the given XR_ENVIRONMENT_BLEND_MODE as according to the OpenXR spec. And better print the error messages. (!345)
  • OpenXR: Validate given displayTime in xrEndFrame as required by the spec. (!345)
  • OpenXR: Validate internal state that we get from the compositor. (!345)
  • OpenXR: Validate time better in xrConvertTimeToTimespecTimeKHR and add better error print. (!348)
  • OpenXR: Correctly translate the XrSwapchainCreateFlags flags to xrt ones. (!349)
  • OpenXR: In order to be able to correctly validate XrPath ids turn them into a atom and keep all created paths in a array. (!349)
  • OpenXR: Give better error messages on invalid poses in quad layers instead of using the simple macro. (!350)
  • OpenXR: Validate poses for project layer views, using the same expressive error messages as the quad layers. (!350)
  • OpenXR: Translate the swapchain usage bits from OpenXR enums to Monado's internal enums. (!350)
  • OpenXR: Report a spec following amount of maximum layers supported. (!354)
  • OpenXR: Correctly reject invalid times given to xrLocateSpace. (!354)
  • OpenXR: Correctly handle the space relation flag bits, some old hacked up code left over since Monado's first days have been removed. (!356)
• Drivers
  • dd: Add a driver for the Google Daydream View controller. (!242)
  • all: Use new pre-filter and 3-DoF filter in drivers. (!249)
  • arduino: Added a Arduino based flexible input device driver, along with Arduino C++ code for it. (!251)
  • psmv: Use all 6 measurements to compute acceleration bias, and port to new IMU prefilter. (!255)
  • v4l2: Add special tweaks for the ELP camera. (!266)
  • vive: Add basic 3DOF driver for Vive Wand Controller with full input support and Valve Index Controller with partial input support. (!281)
  • psvr: Use a better 3dof fusion for the PSVR when no tracking is available. (!282)
  • psvm: Move the led and rumble updating from the application facing update_inputs function to the internal thread instead. (!287)
  • psmv: Fix failure to build from source on PPC. (!288, #69)
• Compositor
  • main: Fix XCB memory leaks and correctly use XCB/Xlib interop. (!257)
  • main: Shorten Vulkan initializers. (!259)
  • main: Port XCB and direct mode back ends to plain C. (!262)
  • main: Add support for Vive Pro, Valve Index, Oculus DK1, DK2 and CV1 to NVIDIA direct mode. (!263)
  • client: Make sure that the number of images is decided by the fd compositor. (!270)
  • main: Split RandR and NVIDIA direct mode window back ends. (!271)
  • main: Improve synchronization and remove redundant vkDeviceWaitIdle calls. (!277)
  • main: Delay the destruction of swapchains until a time where it is safe, this allows swapchains to be destroyed from other threads. (!278)
  • client: Propegate the supported formats from the real compositor to the client ones. (!282)
  • renderer: Change the idle images colour from bright white to grey. (!282)
  • main: Add support for multiple projection layers. (!340)
  • main: Implement quad layers. (!340)
  • main: Only allocate one image for static swapchains. (!349)
• Helper Libraries

  • tracking: Improve readability and documentation of IMU fusion class. (!255)
  • u/file: Add file helpers to load files from config directory. (!266)
  • u/json: Add bool getter function. (!266)
  • tracking: Expose save function with none hardcode path for calibration data. (!266)
  • tracking: Remove all path hardcoded calibration data loading and saving functions. (!266)
  • threading: New helper functions and structs for doing threaded work, these are on a higher level then the one in os wrappers. (!278)
  • threading: Fix missing #pragma once in os/os_threading.h. (!282)
  • u/time: Temporarily disable the time skew in time state and used fixed offset instead to fix various time issues in st/oxr. Will be fixed properly later. (!348)
  • math: Correctly validate quaternion using non-squared "length" instead of squared "length", certain combinations of elements would produce valid regular "length" but not valid squared ones. (!350)
• Misc. Features
  • build: Refactor CMake build system to make static (not object) libraries and explicitly describe dependencies. (!233, !237, !238, !240)
  • os/ble: Add utility functionality for accessing Bluetooth Low-Energy (Bluetooth LE or BLE) over D-Bus, in os/os_ble.h and os/os_ble_dbus.c. (!242)
  • util: Add some bit manipulation helper functions in util/u_bitwise.c and util/u_bitwise.c. (!242)
  • tracking: Make stereo_camera_calibration reference counted, and have the prober, not the calibration, call the save function. (!245)
  • math: Expand algebraic math functions in math/m_api.h, math/m_vec3.h and math/m_base.cpp. (!249)
  • math: Add pre-filter and a simple understandable 3-DoF fusion filter. (!249)
  • build: Enable the build system to install monado-cli and monado-gui. (!252)
  • build: Unify inputs for generated files between CMake and Meson builds. (!252)
  • build: Support building with system cJSON instead of bundled copy. (!284, #62)
  • ci: Perform test builds using the Android NDK (for armeabi-v7a and armv8-a). This is not a full Android port (missing a compositor, etc) but it ensures we don't add more Android porting problems. (!292)
• Misc. Fixes
  • os/ble: Check if org.bluez name is available before calling in os/os_ble_dbus.c. (#65, #64, !265)
  • README: Added information to the README containing OpenHMD version requirement and information regarding the requirement of GL_EXT_memory_object_fd and limitations on Monado's compositor. (!4)
  • build: Fix build issues and build warnings when 32-bit. (!230)
  • os/ble: Fix crash due to bad dbus path, triggered by bad return checking when probing for BLE devices. (!247)
  • d/dd: Use the correct time delta in DayDream driver. (!249)
  • doc: Stop changelog snippets from showing up in 'Related Pages' (!253)
  • build: Fix meson warnings, increase compiler warning level. (!258)
  • os/ble: Fix leak in os/os_ble_dbus.c code when failing to find any device. (!264)
  • os/ble: Make ble code check for some error returns in os/os_ble_dbus.c. (!265)
  • u/hashset: Fix warnings in util/u_hashset.h after pedantic warnings were enabled for C++. (!268)
  • build: Fix failure to build from source on ppc64 and s390x. (!284)
  • build: Mark OpenXR runtime target in CMake as a MODULE library, instead of a SHARED library. (!284)
  • windows: Way way back when Gallium was made auxiliary was named aux but then it was ported to Windows and it was renamed to auxiliary since Windows is allergic to filenames that match its device names (e.g., AUX, CON, PRN, etc.). Through the ages, this knowledge was lost and so we find ourselves with the same problem. Although Monado inherited the correct name, the same old mistake was made in docs. (!314)
  • build: For CMake rename (nearly) all build options so they begin with XRT_ and match the defines used in the source. You will probably want to clear your build directory and reconfigure from scratch. (!327)
  • ipc: Correctly set the shared semaphore value when creating it, the wrong value resulted in the client not blocking in xrWaitFrame. (!348)
  • ipc: Previously some arguments where dropped at swapchain creation time, correct pass them between the client and server. (!349)
