chances of the Vulkan driver supporting a reasonable set of usage flags
for the formats.

Ryan Pavlik 9087d1c7a9 xrt: Use our generic graphics buffer typedefs all over.

Christoph Haag 026cc64681 comp: make nvidia display selectable with XRT_COMPOSITOR_FORCE_NVIDIA_DISPLAY 
Allows temporarily adding a nvidia display name string to the whitelist without recompiling.
 2020-08-11 00:44:31 +02:00

Jakob Bornecrantz ca786df18c xrt: Make xrt_swapchain_create_info argument const 2020-08-07 19:15:18 +01:00
Christoph Haag e48c748a57 xrt: suggest correct GPU in xrGetVulkanGraphicsDevice() 
As before, on the service side the GPU index the compositor runs on can be selected with
* XRT_COMPOSITOR_FORCE_GPU_INDEX=INDEX1

By default xrGetVulkanGraphicsDevice() will suggest the same GPU the compositor runs on.

It is also possible to override the GPU index suggested to applications with
* XRT_COMPOSITOR_FORCE_CLIENT_GPU_INDEX=INDEX2

The reason this is both done on the service side is that if compositor and client run
on different GPUs, the swapchains use linear tiling instead of optimal tiling.

To make chosen GPUs comparable across the compositor's and the client's vulkan instance,
VkPhysicalDeviceIDProperties.deviceUUID is used.

Christoph Haag 4ec6f46717 comp/gl: hack: glFlush() before committing a layer 
This works around corruption in layers on several drivers caused by
writes to the OpenGL textures not having finished when used by the
compositor.

This should be properly fixed with external semaphores later.

Lubosz Sarnecki db3a721946 comp/shaders: Remove has_sub option. 
As we have subimage rects for all layers now.

Lubosz Sarnecki 2472deb95a comp/layers: Remove layer type from constructor. 
The value was not used anyway as it is not set at creation time, but
every frame. This avoids some confusion.
 2020-07-16 19:08:10 +02:00
Lubosz Sarnecki 6222de38c9 comp/shaders: Rename quad shaders to layer. 
As the shader is used for all layers we have, the generic name fits
better.
 2020-07-16 19:08:10 +02:00
Lubosz Sarnecki a27164ab43 comp/renderer: Render subimage properties in layer shader. 
This patch passes the offset and extent properties to the layer shader
by extending the uniform. The fragment shader stage now also receives
the transformation uniform, which contains a has_sub boolean to
distinguish if the properties are set, so between projection and quad layers.

To avoid color bleeding the subimage sampling happens on a global pixel
coordinates basis as ivec2 using the GLSL texelFetch function.
Projection layers will be sampled as before.
 2020-07-16 19:08:10 +02:00
Ryan Pavlik 1aa2cdb89a build: Move determination of Vulkan usage to build system. 
Vulkan is still required for most actual uses of Monado, but this
makes the coupling weaker.

Lubosz Sarnecki b1d39e7f07 xrt: Move layer enum to xrt namespace. 2020-06-09 19:04:47 +00:00
Christoph Haag cc9b415a8f xrt: Add xrt_result_t return type to many functions 
Many functions returned void and were assumed to always succeed, and some functions
returned only a bool to indicate vague success/failure.

Now that these functions get piped over IPC all of them have to be able to indicate
an IPC failure like for example an unreachable service.

With the xrt_result_t return type they now have the opportunity to report various
types of failures.

Ryan Pavlik bc6cc85e7d xrt: Improve doxygen documentation. 2020-06-03 16:28:18 -05:00
Lubosz Sarnecki 435d5a9b9e c/comp: Remove internal Vulkan validation init. 
Instead of maintaining this chunk of code and build options, the Vulkan
loader can be used to load up validation. This has the advantage that no
layer name needs to be hard coded inside Monado, which was subject of
change recently.

Instead of using our own environment variable we can easily set the one
from the loader, e.g. `VK_INSTANCE_LAYERS=VK_LAYER_KHRONOS_validation`.
 2020-06-03 11:17:51 +00:00

Lubosz Sarnecki 7186bddf60 c/comp+ipc: Use array indices again. 
This fixes a regression introduced by the IPC and layer rendering
patchsets and passes the array_index to the correct places, so the
correct VkImageView is used instead of the one with index 0.

Lubosz Sarnecki d0539161dc c/renderer+ipc: Use layer renderer. 
Make the renderer and IPC aware of multiple projection and quad layers
using the layer renderer.

Remove redundant code related to idle images and imported buffers and
command buffer rebuild, since we now always just display the layer
renderer's frame buffer.

Get view and projection properties from xrt_device.

Ryan Pavlik 233c63a773 comp: Fix Wint-to-pointer-cast warnings on 32-bit. 
Culprit is a Vulkan non-dispatchable handle:
Fix is simpler than for OpenXR because we aren't a Vulkan

Don't wait on device idle multiple times in resize.

Validation on NVIDA and AMD is happy when only keeping
the two idles when resizing and destroying the swapchain.

Lubosz Sarnecki bda1cdaee1 c/renderer: Use only one buffer counter cache. 
Use the same counter for frame and command buffers, as their number is
equal, which is retrieved from swapchain.image_count.
Use the struct member num_buffers in favor of passing it as parameter.
Reuse some command buffer functions.

Lubosz Sarnecki ddc7ceb214 c/renderer: Don't wait on device idle after acquiring swapchain image. 
vkAcquireNextImageKHR is synchronized with the present_complete
semaphore.

Lubosz Sarnecki 7da70568be c/direct_mode: Use VkDisplayModeParametersKHR. 
In favor of own struct to determine best available mode.
The loop now also starts as one, as we do not need compare the 0th mode
it itself and returns if there is only one mode.

Lubosz Sarnecki 7afb012544 c/direct_mode: Check if NVIDIA path found any displays. 
This helps failing earlier with an NVIDIA Optimus setup, which currently
is not supported.

Lubosz Sarnecki b399960f67 c/direct_mode: Cast display int only for comparision with size(). 
It is clearer to leave `int display` from settings as signed integer and
cast only for the comparision with the unsigned vector size.

Lubosz Sarnecki 865b668ee7 c/xcb: Port to plain C. 
The code was already essentialy C, just needed to replace the pairs with
structs and the vector with an array, it was fixed length anyway.

The code feels more natural in C.
