Aidan Thornton 3485babd71 comp: rotate the compute compositor's distortion texture 
Some devices like Android smartphones have displays which are
rotated, meaning the compositor needs to rotate its output.

Add support for this to the compute compositor by rotating the
contents of the textures it uses for distortion lookups. This
requires postponing the calculation of that texture and adding
code to recreate it if the rotation changes (which is allowed,
but unlikely to happen in practice.)

Christoph Haag c24e482e5e st/oxr: Make OpenXR timestamps relative to service startup 
This solves a problem where OpenXR timestamps could become invalid
(negative) in certain circumstances:

The timestamps that the OpenXR state tracker returned were offset such
that they appeared to start at OpenXR application startup time.

However monado-service is a long running service using system timestamps.
Because of this, if monado-service started work using a system timestamp
acquired before an OpenXR application started, then this system timestamp
could not be converted into an OpenXR without becoming invalid.

With this change, the OpenXR timestamps for OpenXR applications are offset
such that they appear to start at monado-service startup time instead.

As a side effect, all OpenXR applications connected to the same
monado-service instance will receive timestamps from the same domain.

Mateo de Mayo 6e16959098 d/vive: Add vive_source to convert v4l2 timestamps into monotonic clock 
Use a sink in the middle of the stream to correct for v4l2 timestamps with
hardware timestamps to monotonic clock.

This sink, together with other utilities related to data streaming, lives in a
new vive_source entity, with similar functionality to wmr_source or rs_source.

The vive_source lifetime is managed by the builder xfctx, which prevents
deallocation dependencies between vive_device and the v4l2_fs to cause segfaults.

bjorn 6275c4de10 c/main: comp_renderer uses queue from vk bundle; 
The vk bundle currently creates a single queue, calls vkGetDeviceQueue,
and stores it in the bundle.  There's only ever 1 queue from 1 queue
family right now, even when using the compute compositor.

It doesn't really make sense for the renderer to re-request this queue
instead of using the one in the bundle.  If we wanted to store a local
version to it, it should probably be assigned directly (i.e. r->queue =
vk->queue) to ensure that it's the same.  If we decide we want multiple
queues later, that would be a good time to add this sort of thing back.

bjorn 128ea42915 c/render: inline vk_command_buffer helper; 
It's not really abstracting much anymore, and makes it more difficult to
see what's going on.
 2022-07-01 22:01:32 +00:00
bjorn 4c09d20f80 c/render: render_resources has its own command pool; 
Currently, there is a single command pool in the vk bundle, shared by
everyone.  Since command pools (and command buffers allocated from those
pools) can only be used on one thread at a time, this requires locking.
However, the main point of having these annoying command pool things in
the first place is that you can use one for each thread/lifetime/area in
the app and avoid the overhead of the locks (both computational and
cognitive).

In this change I have given the rendering bits of the compositor its own
command pool.  Instead of allocating and freeing a command buffer every
frame, a single command buffer is allocated from the pool during
initialization, and the pool is reset at the beginning of each frame.
Normally, multiple pools would need to be used, but this is not
necessary in monado because frames are serialized. The `TRANSIENT` and
`ONE_TIME_SUBMIT` flags have been added, which can allow for some driver
optimizations.  The render code no longer takes out the command pool
mutex.  The shared command pool is still there for a few remaining
places where vulkan work needs to be done outside the compositor.

I used the command buffer vulkan helpers when possible, but I would
maybe propose the idea of removing them, since they aren't really
wrapping much at this point.  The `C` macro helps a lot and it's a bit
easier to see the Vulkan details in front of you instead of needing to
switch back and forth between the helper.

Later, I think it would be cool to apply and document some constraints
like "the queue is only accessed in functions XYZ, the render_resources
command pool must only be accessed in layer_commit from 1 thread" etc.

Mateo de Mayo 008ba2433b d/wmr: Refactor how precomputed transforms work 
Hopefully this is an improvement and not just a rewrite. Some ideas were:
1. Keep poses in WMR space as much as possible.
2. Add an explicit function that precomputes a handful of transforms that allow
   converting between WMR and OpenXR coordinates.
3. Make naming of variables in line with a relatively common T_A_B notation.
4. I wasn't able to figure out why `wmr_config_compute_pose` worked before,
   in any case, hopefully the new notation convention helps understanding
   why P_oxr_{acc,gyr} work.

Campbell Suter bb414f7d39 d/qwerty: Fix the aim pose not being HMD-relative 
Commit e41cc1eec3 added support for the XRT_INPUT_SIMPLE_AIM_POSE pose
input in the QWERTY driver. Unfortunately it didn't change the code that
identifies whether the pose for a controller or HMD is being read.

In the QWERTY driver, the hands are positioned relative to the HMD, so
if you move or rotate the HMD the hands stay in the same place
on-screen. Whether a pose lookup is multiplied by the HMD transform
depends on whether the pose being looked up is that of a controller.

Thus the aim pose would not be positioned relative to the HMD.

Campbell Suter 45703f0952 d/remote: Mark pose as invalid when deactivated 
Previously the pose on the remote driver controllers would always have
the set pose and the valid-tracking flags set. Leaving the pose set
makes sense (you might want to track how your game behaves when a
controller looses tracking but still has a pose set, for example
tracking issues caused by occlusion) but it wasn't possible to test with
the pose marked as not being tracked.

Therefore this patch deactivates the tracking flags when the controller
is not marked as active.

Mateo de Mayo 2785c6bcfa d/wmr: Wait until first IMU sample to send frames 
In an Odyssey+, it seems that before the first IMU sample the frame timestamps
do not make sense and thus can make the SLAM system crash.

Also, this commit enables SLAM submission from start unless specified.
SLAM for WMR headsets now works "out of the box" :)

Mateo de Mayo 05b8e320a5 a/math: Add multiple isometry-related matrix functions 
An isometry is a rigid body transform. In this context I'm using the term to
refer to 4x4 homogeneous matrices in SE(3). I.e., matrices comprised of a
3x3 rotation, a 3x1 translation, and a [0,0,0,1] last row.
This matrix represent both rigid body transforms.

Mateo de Mayo 8b2fa955b9 a/math: Fix matrix identities and use isometry 
Isometry3f is a 4x4 matrix transform that performs only rotation and translation
(an SE(3) matrix). Its inverse can be computed trivially by Eigen compared to a
regular 4x4 transform.

bjorn d3a0f10acb c/client: rm client swapchain layout transition; 
This was only there to satisfy a validation layer bug, which appears
to have since been fixed.  It doesn't make sense to transition an XR
swapchain image to PRESENT_SRC, and the client transitions from
UNDEFINED anyway when acquiring the image.

This also fixes a case where monado violates the OpenXR specification:

> The list of OpenXR functions where the OpenXR runtime may access the
> VkQueue are:
> - xrBeginFrame
> - xrEndFrame
> - xrAcquireSwapchainImage
> - xrReleaseSwapchainImage
> The runtime must not access the VkQueue in any OpenXR function that is
> not listed above or in an extension definition.

bjorn 2d954d84af c/render: Fix invalid synchronization when uploading images; 
`queue_upload_for_first_level_and_layer` uploads pixels to an image.

It performs a layout transition, does the copy, and does another layout
transition.  There is an execution dependency between the the copy and
the second layout transition, but the memory dependency was missing.

Caught/tested via enabling synchronization validation.
