Monado 21.0.0 (2021-01-28)

• Major changes
  • Adds a initial SteamVR driver state tracker and target that produces a SteamVR plugin that enables any Monado hardware driver to be used in SteamVR. This is the initial upstreaming of this code and has some limitations, like only having working input when emulating a Index controller. (!583)
• XRT Interface
  • Add xrt_binding_profile struct, related pair structs and fields on xrt_device to allow to move the static rebinding of inputs and outputs into device drivers. This makes it easier to get a overview in the driver itself which bindings it can bind to. (!587)
  • xrt: Generate bindings for Monado and SteamVR from json. (!638)
  • xrt: Introduce xrt_system_compositor, it is basically a analogous to XrSystemID but instead of being a fully fledged xrt_system this is only the compositor part of it. Also fold the prepare_session function into the create native compositor function to simplify the interface. (!652)
  • Expose more information on the frameservers, like product, manufacturer and serial. (!665)
  • Add XRT_FORMAT_BAYER_GR8 format. (!665)
• State Trackers
  • st/oxr: Add OXR_FRAME_TIMING_SPEW for basic frame timing debug output. (!591)
  • OpenXR: Make sure to restore old EGL display/context/drawables when creating a client EGL compositor. (!602)
  • GUI: Expand with support for controlling the remote driver hand tracking. (!604)
  • st/oxr: Implement XR_KHR_vulkan_enable2 (!633)
  • st/oxr: Add OXR_TRACKING_ORIGIN_OFFSET_{X,Y,Z} env variables as a quick way to tweak 6dof tracking origins. (!634)
  • OpenXR: Be more relaxed with Quat validation, spec says within 1% of unit length, normalize if not within float epsilon. (!659)
• Drivers
  • North Star: Fix memory leak in math code. (!564)
  • psvr: Rename some variables for better readability. (!597)
  • openhmd: Fix viewport calculation of rotated displays. (!600)
  • remote: Add support for simulated hand tracking, this is based on the curl model that is used by the Valve Index Controller. (!604)
  • android: Acquire device display metrics from system. (!611)
  • openhmd: Rotate DK2 display correctly. (!628)
  • d/psmv: The motor on zcmv1 does not rumble at amplitudes < 0.25. Linear rescale amplitude into [0.25, 1] range. (!636)
  • v4l2: Expose more information through new fields in XRT interface. (!665)
  • v4l2: Allocate more buffers when streaming data. (!665)
• IPC
  • ipc: Port IPC to u_logging. (!601)
  • ipc: Make OXR_DEBUG_GUI work with monado-service. (!622)
• Compositor
  • comp: Add basic frame timing information to XRT_COMPOSITOR_LOG=trace. (!591)
  • main: Refactor how the compositor interacts with targets, the goal is to enable the compositor to render to destinations that isn't backed by a VkSwapchain. Introduce comp_target and remove comp_window, also refactor vk_swapchain to be a sub-class of comp_target named comp_target_swapchain, the window backends now sub class comp_target_swapchain. (!599)
  • Implement support for XR_KHR_composition_layer_equirect (equirect1). (!620, !624)
  • comp: Improve thread safety. Resolve issues in mutlithreading CTS. (!645)
  • main: Lower priority on sRGB format. This works around a bug in the OpenXR CTS and mirrors better what at least on other OpenXR runtime does. (!671)
• Helper Libraries
  • os/time: Make timespec argument const. (!597)
  • os/time: Add a Linux specific way to get the realtime clock (for RealSense). (!597)
  • math: Make sure that we do not drop and positions in poses when the other pose has a non-valid position. (!603)
  • aux/vk: vk_create_device now takes in a list of Vulkan device extensions. (!605)
  • Port everything to u_logging. (!627)
  • u/hand_tracking: Tweak finger curl model making it easier to grip ingame objects. (!635)
  • math: Add math_quat_validate_within_1_percent function. (!659)
  • u/sink: Add Bayer format converter. (!665)
  • u/distortion: Improve both Vive and Index distortion by fixing polynomial math. (!666)
  • u/distortion: Improve Index distortion and tidy code. While this touches the Vive distortion code all Vive headsets seems to have the center set to the same for each channel so doesn't help them. And Vive doesn't have the extra coefficient that the Index does so no help there either. (!667)
• Misc. Features
  • Work toward a Win32 port. (!551, !605, !607)
  • Additional improvements to the Android port. (!592, !595, #105)
• Misc. Fixes
  • steamvr: Support HMDs with rotated displays (!600)

Monado 0.4.1 (2020-11-04)

• State Trackers
  • st/oxr: Fix for new conformance tests for xrWaitFrame, xrBeginFrame, xrEndFrame call order. Also fix OpenXR state transition logic depending on a synchronized frame loop. (!589, !590)

Monado 0.4.0 (2020-11-02)

• XRT Interface

  • add xrt_device_type to xrt_device to differentiate handed controllers from controllers that can be held in either hand. (!412)

  • Rename functions and types that assumed the native graphics buffer handle type was an FD: in auxiliary/vk/vk_helpers.{h,c} vk_create_image_from_fd -> vk_create_image_from_native, in the XRT headers struct xrt_compositor_fd -> xrt_compositor_native (and method name changes from xrt_comp_fd_... -> xrt_comp_native_...), struct xrt_swapchain_fd -> struct xrt_swapchain_native, struct xrt_image_fd -> struct xrt_image_native, and corresponding parameter/member/variable name changes (e.g. struct xrt_swapchain_fd *xscfd becomes struct xrt_swapchain_native *xscn). (!426, !428)

  • Make some fields on xrt_gl_swapchain and xrt_vk_swapchain private moving them into the client compositor code instead of exposing them. (!444)

  • Make xrt_compositor::create_swapchain return xrt_result_t instead of the swapchain, this makes the methods on xrt_compositor more uniform. (!444)

  • Add the method xrt_compositor::import_swapchain allowing a state tracker to create a swapchain from a set of pre-allocated images. Uses the same xrt_swapchain_create_info as xrt_compositor::create_swapchain. (!444)

  • Make xrt_swapchain_create_flags swapchain static image bit match OpenXR. (!454)

  • Add XRT_SWAPCHAIN_USAGE_INPUT_ATTACHMENT flag to xrt_swapchain_usage_bits so that a client can create a Vulkan swapchain that can be used as input attachment. (!459)

  • Remove the flip_y parameter to the creation of the native compositor, this is now a per layer thing. (!461)

  • Add xrt_compositor_info struct that allows the compositor carry information to about it's capbilities and it's recommended values. Not everything is hooked up at the moment. (!461)

  • Add defines for underlying handle types. (!469)

  • Add a native handle type for graphics sync primitives (currently file descriptors on all platforms). (!469)

  • Add a whole bunch of structs and functions for all of the different layers in OpenXR. The depth layer information only applies to the stereo projection so make a special stereo projection with depth layer. (!476)

  • Add xrt_image_native_allocator as a friend to the compositor interface. This simple interface is intended to be used by the IPC interface to allocate xrt_image_native on the client side and send those to the service. (!478)

  • Re-arrange and document xrt_image_native, making the size field optional. (!493)

  • Add const to all compositor arguments that are info structs, making the interface safer and more clear. Also add max_layers field to the xrt_compositor_info struct. (!501)

  • Add xrt_space_graph struct for calculating space relations. This struct and accompanying makes it easier to reason about space relations than just functions operating directly on xrt_space_relation. The code base is changed to use these new functions. (!519)

  • Remove the linear_acceleration and angular_acceleration fields from the xrt_space_relation struct, these were not used in the codebase and are not exposed in the OpenXR API. They can easily be added back should they be required again by code or a future feature. Drivers are free to retain this information internally, but no longer expose it. (!519)

  • Remove the out_timestamp argument to the xrt_device::get_tracked_pose function, it's not needed anymore and the devices can do prediction better as it knows more about it's tracking system the the state tracker. (!521)

  • Replace mesh generator with compute_distortion function on xrt_device. This is used to both make it possible to use mesh shaders for devices and to provide compatibility with SteamVR which requires a compute_distortion function as well.

    The compositor uses this function automatically to create a mesh and uses mesh distortion for all drivers. The function compute_distortion default implementations for none, panotools and vive distortion models are provided in util. (!536)

  • Add a simple curl value based finger tracking model and use it for vive and survive controllers. (!555)

• State Trackers
  • OpenXR: Add support for attaching Quad layers to action sapces. (!437)
  • OpenXR: Use initial head pose as origin for local space. (!443)
  • OpenXR: Minor fixes for various bits of code: copy-typo in device assignment code; better stub for the unimplemented function xrEnumerateBoundSourcesForAction; better error message on internal error in xrGetCurrentInteractionProfile. (!448)
  • OpenXR: Make the xrGetCurrentInteractionProfile conformance tests pass, needed to implement better error checking as well as generating XrEventDataInteractionProfileChanged events to the client. (!448)
  • OpenXR: Centralize all sub-action path iteration in some x-macros. (!449, !456)
  • OpenXR: Improve the validation in the API function for xrGetInputSourceLocalizedName. (!451)
  • OpenXR: Implement the function xrEnumerateBoundSourcesForAction, currently we only bind one input per top level user path and it's easy to track this. (!451)
  • OpenXR: Properly handle more than one input source being bound to the same action according to the combination rules of the specification. (!452)
  • OpenXR: Fix multiplicity of bounds paths per action - there's one per input/output. (!456)
  • OpenXR: Implement the MND_swapchain_usage_input_attachment_bit extension. (!459)
  • OpenXR: Refactor the native compositor handling a bit, this creates the compositor earlier then before. This allows us to get the viewport information from it. (!461)
  • OpenXR: Implement action set priorities and fix remaining action conformance tests. (!462)
  • st/oxr: Fix crash when calling xrPollEvents when headless mode is selected. (!475)
  • OpenXR: Add stub functions and support plumbing for a lot of layer extensions. (!476)
  • OpenXR: Be sure to return XR_ERROR_FEATURE_UNSUPPORTED if the protected content bit is set and the compositor does not support it. (!481)
  • OpenXR: Update to 1.0.11 and start returning the new XR_ERROR_GRAPHICS_REQUIREMENTS_CALL_MISSING code added in this release. (!482)
  • OpenXR: Enable the XR_KHR_android_create_instance extension. (!492)
  • OpenXR: Add support for creating swapchains with depth formats and submitting depth layers. The depth layers are passed through to the compositor, but are not used yet. (!498)
  • OpenXR: For pose actions the any path (XR_NULL_PATH) needs to be special cased, essentially turning into a separate action sub path, that is assigned at binding time. (!510)
  • OpenXR: More correctly implement xrGetInputSourceLocalizedName allowing apps to more accurently tell the user which input to use. (!532)
  • OpenXR: Pass through equirect layer data to the compositor. (!566)
• Drivers
  • psvr: We were sending in the wrong type of time to the 3DOF fusion code, switch to nanoseconds instead of fractions of seconds. (!474)
  • rs: Make the pose getting from the T265 be threaded. Before we where getting the pose from the update input function, this would cause some the main thread to block and would therefore cause jitter in the rendering. (!486)
  • survive: Add lighthouse tracking system type hydra: Add lighthouse tracking system type (!489)
  • rs: Add slam tracking system type northstar: Use tracking system from tracker (e.g. rs) if available. (!494)
  • psmv: Introduce proper grip and aim poses, correctly rotate the grip pose to follow the spec more closely. The aim poses replaces the previous ball tip pose that was used before for aim. (!509)
  • survive: Implement haptic feedback. (!557)
  • dummy: Tidy the code a bit and switch over to the new logging API. (!572, !573)
  • psvr: Switch to the new logging API. (!573)
  • Add initial "Cardboard" phone-holder driver for Android. (!581)
• IPC
  • Generalize handling of native-platform handles in IPC code, allow bi- directional handle transfer, and de-duplicate code between server and client. (!413, !427)
  • generation: Fix handling 'in_handle' by adding a extra sync round-trip, this might be solvable by using SOCK_SEQPACKET. (!444)
  • Implement the xrt_compositor::import_swapchain function, uses the earlier in_handle work. (!444)
  • proto: Transport the xrt_compositor_info over the wire so that the client can get the needed information. (!461)
  • client: Implement the usage of the xrt_image_native_allocator, currently not used. But it is needed for platforms where for various reasons the allocation must happen on the client side. (!478)
  • client: Add a "loopback" image allocator, this code allocates a swapchain from the service then imports that back to the service as if it was imported. This tests both the import code and the image allocator code. (!478)
  • ipc: Allow sending zero handles as a reply, at least the Linux fd handling code allows this. (!491)
  • Use a native AHardwareBuffer allocator on the client side when building for recent-enough Android. (!493)
  • ipc: Add functionality to disable a device input via the monado-ctl utility, this allows us to pass the conformance tests that requires the runtime to turn off a device. (!511)
• Compositor
  • compositor: Add support for alpha blending with premultiplied alpha. (!425)
  • compositor: Implement subimage rectangle rendering for quad layers. (!433)
  • compositor: Enable subimage rectangle rendering for projection layers. (!436)
  • compositor: Fix printing of current connected displays on nvidia when no whitelisted display is found. (!477)
  • compositor: Add env var to temporarily add display string to nvidia whitelist. (!477)
  • compositor and clients: Use a generic typedef to represent the platform- specific graphics buffer, allowing use of AHardwareBuffer on recent Android. (!479)
  • compositor: Check the protected content bit, and return a non-success code if it's set. Supporting this is optional in OpenXR, but lack of support must be reported to the application. (!481)
  • compositor: Implement cylinder layers. (!495)
  • main: Set the maximum layers supported to 16, we technically support more than 16, but things get out of hand if multiple clients are running and all are using max layers. (!501)
  • main: Add code to check that a format is supported by the GPU before exposing. (!502)
  • compositor: Remove panotools and vive shaders from compositor. (!538)
  • Initial work on a port of the compositor to Android. (!547)
  • render: Implement equirect layer rendering. (!566)
  • main: Fix leaks of sampler objects that was introduced in !566. (!571)
• Helper Libraries
  • u/vk: Remove unused vk_image struct, this is later recreated for the image allocator code. (!444)
  • u/vk: Add a new image allocate helper, this is used by the main compositor to create, export and import swapchain images. (!444)
  • u/vk: Rename vk_create_semaphore_from_fd to vk_create_semaphore_from_native (!469)
  • aux/android: New Android utility library added. (!493, !547, !581)
  • aux/ogl: Add a function to compute the texture target and binding enum for a given swapchain image creation info. (!493)
  • util: Tidy hand tracking header. (!574)
  • math: Fix doxygen warnings in vector headers. (!574)
• Misc. Features
  • Support building in-process Monado with meson. (!421)
  • Allow building some components without Vulkan. Vulkan is still required for the compositor and therefore the OpenXR runtime target. (!429)
  • Add an OpenXR Android target: an APK which provides an "About" activity and eventually, an OpenXR runtime. (!574, !581)
• Misc. Fixes
  • No significant changes

Monado 0.3.0 (2020-07-10)

• Major changes
  • Centralise the logging functionality in Monado to a single util helper. Previously most of our logging was done via fprints and gated behind booleans, now there are common functions to call and a predfined set of levels. (!408, !409)
• XRT Interface
  • compositor: Remove the array_size field from the struct, this was the only state tracker supplied value that was on the struct, only have values that the compositor decides over on the struct. (!359)
  • Improve Doxygen documentation of interfaces. Now the inheritance structure and implementation of interfaces is shown in the docs, and helper functions that call through function pointers are listed as "member functions", to help developers understand the internal structure of Monado better. (!365, !367)
  • xrt: Add xrt_result_t return type to many compositor functions that previously had no way to indicate failure. (!369)
  • compositor: Introduce xrt_swapchain_create_info simplifying the argument passing between various layers of the compositor stack and also simplify future refactoring projects. (!407)
• State Trackers
  • OpenXR: Update headers to 1.0.9. (!358)
  • OpenXR: Verify that the XrViewConfigurationType is supported by the system as required by the OpenXR spec in xrEnumerateEnvironmentBlendModes. (!359)
  • OpenXR: Return the correct error code when verifying the sub action, if it is a valid sub action path but not given at action creation we should return XR_ERROR_PATH_UNSUPPORTED. (!359)
  • OpenXR: Validate the subImage data for both projection and quad layers layers, refactor code out so it can be shared with the different types of layers. Need to track some state on the oxr_swapchain in order to do the checking. (!359)
  • OpenXR: Correct the return error code for action and action set localized name validation. (!359)
  • OpenXR: Correct the error messages on sub action paths errors. (!359)
  • OpenXR: Track the name and localized name for both actions and action sets, that way we can make sure that there are no duplicates. This is required by the spec. (!359)
  • OpenXR: Do better checking if action sets and actions have been attached to the session or not. (!359)
  • OpenXR: Validate the arguments for xrSuggestInteractionProfileBindings better so that it follows the spec better. (!359)
  • OpenXR: Rework the logging formatting of error messages, this makes it easier to read for the application developer. (!359)
  • OpenXR: Correctly ensure that the application has called the required get graphics requirements function when creating a session. (!359)
  • OpenXR: When a XrSession is destroyed purge the event queue of any events that references to it so that no events gets delivered to the applications with stales handles. (!359)
  • OpenXR: Make the event queue thread safe, all done with a simple mutex that is not held for long at all. (!359)
  • OpenXR: A major overhaul of the swapchain acquire, wait and release code. This makes it almost completely conformant with the spec. Tricky parts include that multiple images can be acquired, but only one can be waited on before being released. (!359)
  • OpenXR: Enforce that static swapchains can only be acquired once, this is required by the spec and make sure that a image is only rendered to once, and allows the runtime to perform special optimizations on the image. (!359)
  • OpenXR: Make the function xrGetReferenceSpaceBoundsRect at least conform to the spec without actually implementing it, currently we do not track bounds in Monado. (!359)
  • OpenXR: Make the session state changes obey the specification. The code is fairly hair as is and should be improved at a later time. (!359)
  • OpenXR: Use the correct XrPath for /user/gamepad while it sits in the users hand itsn't /user/hand/gamepad as previously believed. (!359)
  • OpenXR: Where used make sure we verify the view configuration type is a valid enum value, the code is setup so that we in the future can support new values via extensions easily. (!368)
  • OpenXR: More correctly verify the interactive profile binding data, including the given interactive profile is correct and the binding point is valid. (!377)
  • OpenXR: Transform input types in a somewhat flexible, composable way. Also, do conversion at sync time, and use the transformed values to evaluate if the input has changed, per the spec. (!379)
  • OpenXR: Tidy the extensions generated by the script and order them according to extension prefix, starting with KHR, EXT, Vendor, KHRX, EXTX, VendorX. Also rename the MND_ball_on_stick_controller to MNDX_ball_on_a_stick_controller. (!410)
  • OpenXR: Fix overly attached action sets, which would appear to be attached to a session even after the session has been destroyed. Also tidy up comments and other logic surrounding this. (!411)
• Drivers
  • psvr: Normalize the rotation to not trip up the client app when it gives the rotation back to st/oxr again. (!359)
  • vive: Create vive_config module to isolate config code and avoid duplication between controller and headset code. vive: Probe for controllers in vive_proper interface. vive: Fix a bug where using the Vive Pro crashed Monado. vive: Fix a bug where the controller didn't parse JSON vectors correctly. vive: Move missing functions to and use u_json. (!405)
  • vive: Add support for Gen1 and Gen2 Vive Trackers. (!406)
  • vive: Port to new u_logging API. (!417)
  • comp: Set a compositor window title. (!418)
• IPC
  • server: Almost completely overhaul the handling of swapchain life cycle including: correctly track which swapchains are alive; reuse ids; enforce the maximum number of swapchains; and destroy underlying swapchains when they are destroyed by the client. (!359)
  • util: Make sure to not access NULL control messages, say in the case of the server failing to create a swapchain. Also add a whole bunch of paranoia when it comes to the alignment of the control message buffers. (!359)
  • ipc: Return XR_ERROR_INSTANCE_LOST on IPC errors. (!369)
• Compositor
  • main: Include <math.h> in layers renderer for missing tanf function. (!358)
  • swapchain: Give out the oldset image index when a image is acquired. This logic can be made better, but will work for the good case. (!359)
  • swapchain: Close any FDs that are still valid, for instance the ipc server copies the FDs to the client. (!359)
  • client: When we give a image fd to the either OpenGL or Vulkan it is consumed and can not be rused. So make sure that it is set to an invalid fd value on the xrt_image_fd on the owning xrt_swapchain_fd. (!359)
  • main: We were alpha blending all layers previously, but now we support the layer flag that OpenXR gives us. We do this by using different VkImageViews with different component swizzles. (!394)
  • layer_rendering: Use the visibility flags on quad to correctly show the layers in each eye. (!394)
• Helper Libraries
  • os/threading: Include xrt_compiler.h to fix missing stdint types. (!358)
  • util: Add a very simple fifo for indices, this is used to keep track of swapchain in order of age (oldness). (!359)
  • util: Expand u_hashset to be able to automatically allocate a u_hashet_item and insert it. (!359)
• Misc. Features
  • build: Allow enabling inter-procedural optimization in CMake GUIs, if supported by platform and compiler. (!330)
• Misc. Fixes
  • No significant changes

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)

  • 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: Add image undistort/normalize cache mechanism, to avoid needing to remap every frame. (!255)
  • 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 non-hardcoded 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)
