## 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](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/426),
[!428](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- Make `xrt_compositor::create_swapchain` return xrt_result_t instead of the
swapchain, this makes the methods on `xrt_compositor` more uniform.
([!444](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- Make `xrt_swapchain_create_flags` swapchain static image bit match OpenXR.
([!454](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/459))
- Remove the `flip_y` parameter to the creation of the native compositor, this
is
now a per layer thing.
([!461](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/461))
- Add defines for underlying handle types.
([!469](https://gitlab.freedesktop.org/monado/monado/merge_requests/469))
- Add a native handle type for graphics sync primitives (currently file
descriptors on all platforms).
([!469](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/478))
- Re-arrange and document `xrt_image_native`, making the `size` field optional.
([!493](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/536))
- Add a simple curl value based finger tracking model and use it for vive and
survive controllers.
([!555](https://gitlab.freedesktop.org/monado/monado/merge_requests/555))
- State Trackers
- OpenXR: Add support for attaching Quad layers to action sapces.
([!437](https://gitlab.freedesktop.org/monado/monado/merge_requests/437))
- OpenXR: Use initial head pose as origin for local space.
([!443](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/448))
- OpenXR: Make the `xrGetCurrentInteractionProfile` conformance tests pass,
needed
to implement better error checking as well as generating
`XrEventDataInteractionProfileChanged` events to the client.
([!448](https://gitlab.freedesktop.org/monado/monado/merge_requests/448))
- OpenXR: Centralize all sub-action path iteration in some x-macros.
([!449](https://gitlab.freedesktop.org/monado/monado/merge_requests/449),
[!456](https://gitlab.freedesktop.org/monado/monado/merge_requests/456))
- OpenXR: Improve the validation in the API function for
`xrGetInputSourceLocalizedName`.
([!451](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/451))
- OpenXR: Properly handle more than one input source being bound to the same
action
according to the combination rules of the specification.
([!452](https://gitlab.freedesktop.org/monado/monado/merge_requests/452))
- OpenXR: Fix multiplicity of bounds paths per action - there's one per
input/output.
([!456](https://gitlab.freedesktop.org/monado/monado/merge_requests/456))
- OpenXR: Implement the MND_swapchain_usage_input_attachment_bit extension.
([!459](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/461))
- OpenXR: Implement action set priorities and fix remaining action conformance
tests.
([!462](https://gitlab.freedesktop.org/monado/monado/merge_requests/462))
- st/oxr: Fix crash when calling `xrPollEvents` when headless mode is selected.
([!475](https://gitlab.freedesktop.org/monado/monado/merge_requests/475))
- OpenXR: Add stub functions and support plumbing for a lot of layer extensions.
([!476](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/481))
- OpenXR: Update to 1.0.11 and start returning the new
`XR_ERROR_GRAPHICS_REQUIREMENTS_CALL_MISSING` code added in this release.
([!482](https://gitlab.freedesktop.org/monado/monado/merge_requests/482))
- OpenXR: Enable the `XR_KHR_android_create_instance` extension.
([!492](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/510))
- OpenXR: More correctly implement `xrGetInputSourceLocalizedName` allowing apps
to more accurently tell the user which input to use.
([!532](https://gitlab.freedesktop.org/monado/monado/merge_requests/532))
- OpenXR: Pass through equirect layer data to the compositor.
([!566](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/486))
- survive: Add lighthouse tracking system type
hydra: Add lighthouse tracking
system type
([!489](https://gitlab.freedesktop.org/monado/monado/merge_requests/489))
- rs: Add slam tracking system type
northstar: Use tracking system from tracker
(e.g. rs) if available.
([!494](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/509))
- survive: Implement haptic feedback.
([!557](https://gitlab.freedesktop.org/monado/monado/merge_requests/557))
- dummy: Tidy the code a bit and switch over to the new
logging API.
([!572](https://gitlab.freedesktop.org/monado/monado/merge_requests/572),
[!573](https://gitlab.freedesktop.org/monado/monado/merge_requests/573))
- psvr: Switch to the new logging API.
([!573](https://gitlab.freedesktop.org/monado/monado/merge_requests/573))
- Add initial "Cardboard" phone-holder driver for Android.
([!581](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/413),
[!427](https://gitlab.freedesktop.org/monado/monado/merge_requests/427))
- generation: Fix handling 'in_handle' by adding a extra sync round-trip, this
might be solvable by using `SOCK_SEQPACKET`.
([!444](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- Implement the `xrt_compositor::import_swapchain` function, uses the earlier
`in_handle` work.
([!444](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- proto: Transport the `xrt_compositor_info` over the wire so that the client can
get the needed information.
([!461](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/478))
- ipc: Allow sending zero handles as a reply, at least the Linux fd handling code
allows this.
([!491](https://gitlab.freedesktop.org/monado/monado/merge_requests/491))
- Use a native AHardwareBuffer allocator on the client side when building for
recent-enough Android.
([!493](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/511))
- Compositor
- compositor: Add support for alpha blending with premultiplied alpha.
([!425](https://gitlab.freedesktop.org/monado/monado/merge_requests/425))
- compositor: Implement subimage rectangle rendering for quad layers.
([!433](https://gitlab.freedesktop.org/monado/monado/merge_requests/433))
- compositor: Enable subimage rectangle rendering for projection layers.
([!436](https://gitlab.freedesktop.org/monado/monado/merge_requests/436))
- compositor: Fix printing of current connected displays on nvidia when no
whitelisted display is found.
([!477](https://gitlab.freedesktop.org/monado/monado/merge_requests/477))
- compositor: Add env var to temporarily add display string to nvidia whitelist.
([!477](https://gitlab.freedesktop.org/monado/monado/merge_requests/477))
- compositor and clients: Use a generic typedef to represent the platform-
specific graphics buffer, allowing use of `AHardwareBuffer` on recent Android.
([!479](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/481))
- compositor: Implement cylinder layers.
([!495](https://gitlab.freedesktop.org/monado/monado/merge_requests/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](https://gitlab.freedesktop.org/monado/monado/merge_requests/501))
- main: Add code to check that a format is supported by the GPU before exposing.
([!502](https://gitlab.freedesktop.org/monado/monado/merge_requests/502))
- compositor: Remove panotools and vive shaders from compositor.
([!538](https://gitlab.freedesktop.org/monado/monado/merge_requests/538))
- Initial work on a port of the compositor to Android.
([!547](https://gitlab.freedesktop.org/monado/monado/merge_requests/547))
- render: Implement equirect layer rendering.
([!566](https://gitlab.freedesktop.org/monado/monado/merge_requests/566))
- main: Fix leaks of sampler objects that was introduced in !566.
([!571](https://gitlab.freedesktop.org/monado/monado/merge_requests/571))
- Helper Libraries
- u/vk: Remove unused vk_image struct, this is later recreated for the image
allocator code.
([!444](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- u/vk: Add a new image allocate helper, this is used by the main compositor to
create, export and import swapchain images.
([!444](https://gitlab.freedesktop.org/monado/monado/merge_requests/444))
- u/vk: Rename `vk_create_semaphore_from_fd` to `vk_create_semaphore_from_native`
([!469](https://gitlab.freedesktop.org/monado/monado/merge_requests/469))
- aux/android: New Android utility library added.
([!493](https://gitlab.freedesktop.org/monado/monado/merge_requests/493),
[!547](https://gitlab.freedesktop.org/monado/monado/merge_requests/547),
[!581](https://gitlab.freedesktop.org/monado/monado/merge_requests/581))
- aux/ogl: Add a function to compute the texture target and binding enum for a
given swapchain image creation info.
([!493](https://gitlab.freedesktop.org/monado/monado/merge_requests/493))
- util: Tidy hand tracking header.
([!574](https://gitlab.freedesktop.org/monado/monado/merge_requests/574))
- math: Fix doxygen warnings in vector headers.
([!574](https://gitlab.freedesktop.org/monado/monado/merge_requests/574))
- Misc. Features
- Support building in-process Monado with meson.
([!421](https://gitlab.freedesktop.org/monado/monado/merge_requests/421))
- Allow building some components without Vulkan. Vulkan is still required for the
compositor and therefore the OpenXR runtime target.
([!429](https://gitlab.freedesktop.org/monado/monado/merge_requests/429))
- Add an OpenXR Android target: an APK which provides an "About" activity and
eventually, an OpenXR runtime.
([!574](https://gitlab.freedesktop.org/monado/monado/merge_requests/574),
[!581](https://gitlab.freedesktop.org/monado/monado/merge_requests/581))
- Misc. Fixes
- No significant changes
## Monado 0.3.0 (2020-07-10)
- Major changes
