2022-12-06render/vulkan: wait for DMA-BUF fencesSimon Ser
The Vulkan spec doesn't guarantee that the driver will wait for implicitly synchronized client buffers before texturing from them. radv happens to perform the wait, but anv doesn't. Fix this by extracting implicit fences from DMA-BUFs, importing them into Vulkan as a VkSemaphore objects, and make the render pass wait on these VkSemaphores.
2022-11-28render/vulkan: import semaphore to DMA-BUF instead of blockingSimon Ser
Right now the Vulkan renderer blocks until the frame is complete after rendering. This is necessary because Vulkan doesn't interoperate well with implicit sync we use everywhere else. Use the new kernel API to import a sync_file into a DMA-BUF to avoid blocking.
2022-11-24render: stop pulling <wlr/backend.h>Simon Ser
Let's just forward-declare struct wlr_backend instead. We need to fixup the Vulkan renderer: it needs makedev(), which got included by chance via <wlr/backend.h> → <wlr/backend/session.h> → <libudev.h>.
2022-11-11render/vulkan: remove hardcoded validation layersSimon Zeni
Users should use the VK_INSTANCE_LAYERS env var to set layers at runtime
2022-11-11render/vulkan: add a command buffer poolSimon Ser
Before re-using a VkCommandBuffer, we need to wait for its operations to complete. Right now we unconditionally wait for rendering to complete in vulkan_end(), however we have plans to fix this [1]. To fully avoid blocking, we need to handle multiple command buffers in flight at the same time (e.g. for multi-output, or for rendering followed by texture uploads). Implement a pool of command buffers. When we need to render, we pick a command buffer from the pool which has completed its operations. If we don't find one, try to allocate a new command buffer. If we don't have slots in the pool anymore, block like we did before. [1]: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/3574
2022-11-11render/vulkan: switch to timeline semaphoresSimon Ser
Up until now we were using a VkFence for GPU-to-CPU synchronization. This has some limitations that become a blocker when trying to have multiple command buffers in flight at once (e.g. for multi-output). It's desirable to implement a command buffer pool [1], but VkFence cannot be used to track command buffer completion for individual subpasses. Let's just switch to timeline semaphores [2], which fix this issue, make synchronization a lot more ergonomic and are a core Vulkan 1.2 feature.

2022-11-11render/vulkan: add helper to load command function pointerSimon Ser
If NULL is returned by vkGetDeviceProcAddr(), either the driver is buggy, either the wlroots code is buggy. For a valid device and command name, drivers are not allowed to return NULL per the spec. This mirrors what the GLES2 renderer does in load_gl_proc().
2022-11-06render/vulkan: use struct initializersSimon Ser
Instead of filling the fields one by one, use a struct initializer. This avoids repeating the name of the variable and is more consistent with the wlroots code style.
2022-11-06render/vulkan: simplify extension checksSimon Ser
find_extensions() is clunky to use when checking only a single extension, and it's surprising that it returns NULL on success. Simplify by replacing it with a check_extension() function which just checks whether a single extension is in the list.
2022-11-04render/vulkan: remove exts arg from vulkan_instance_create()Simon Ser
2022-10-11Fixed false allocation failedGentaiii
2022-10-10render/vulkan: drop wlr_vk_instance.extensionsSimon Ser
This was unused. Even if it was, it'd be better to have bool fields instead.
2022-09-14render/vulkan: improve format loggingSimon Ser
2022-09-07render/vulkan: drop wlr_vk_device.extensionsSimon Ser
We don't need to store the list of enabled extensions. While at it, rename variables to be less confusing.
2022-09-07render/vulkan: drop ext params from vulkan_device_create()Simon Ser
These are unused.
2022-01-19render/vulkan: log physical device driver nameSimon Ser
This can be useful to figure out why a required feature is missing, e.g. as in [1]. We check VK_EXT_physical_device_drm availability after printing the driver name. [1]: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3358
2021-10-18render/vulkan: add Vulkan renderernyorain
This new renderer is implemented with the existing wlr_renderer API (which is known to be sub-optimal for some operations). It's not used by default, but users can opt-in by setting WLR_RENDERER=vulkan. The renderer depends on VK_EXT_image_drm_format_modifier and VK_EXT_physical_device_drm.
