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.
2022-12-02render/vulkan: make shm/dmabuf split clearer in wlr_vk_format_propsSimon Ser
struct wlr_vk_format_props contains a mix of properties for shm and dmabuf, and it's not immediately clear which fields are for which kind of buffer. Use a nested struct to group the fields.
2022-12-02render/vulkan: make vulkan_format_props_find_modifier() return value constSimon Ser
2022-12-02render/vulkan: drop "_format" in wlr_vk_format fieldsSimon Ser
"format" is already in the name, no need to repeat ourselves. `format->vk_format` sounds a bit redundant.
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.
2022-11-28render/vulkan: release stage buffers after command buffer completesSimon Ser
We need to wait for the pending command buffer to complete before re-using stage buffers. Otherwise we'll overwrite the stage buffer with new contents before the texture is fully uploaded.
2022-11-28render/vulkan: destroy textures after command buffer completesSimon Ser
We need to wait for any pending command buffer to complete before we're able to fully destroy a struct wlr_vk_texture: the Vulkan spec requires the VkDescriptorSet to be kept alive. So far we've done this in vulkan_end(), after blocking until the command buffer completes. We'll soon stop blocking, so move this logic in get_command_buffer(), where we check which commands buffers have completed in a non-blocking fashion.
2022-11-28render/vulkan: drop unused fields from wlr_vk_format_modifier_propsSimon Ser
export_imported is never used, and dmabuf_flags is already checked in query_modifier_support().
2022-11-25render/vulkan: align staging buffers for texture uploadManuel Stoeckl
vkCmdCopyBufferToImage requires that the buffer offset be a multiple of the texel block size, which for single plane uncompressed formats is the same as the number of bytes per pixel. This commit adds an alignment parameter to vulkan_get_stage_span which ensures that the provided span (and the sequence of image copy operations derived which use it) have this alignment.
2022-11-25render/vulkan: add support for RGB565 texture formatManuel Stoeckl
Since this does not have a matching _SRGB-type vulkan format, add a new shader variant/pipeline to perform the sRGB->linear texture conversion.
2022-11-15render/vulkan: add wlr_vk_texture_has_alphazccrs
Allow to get whether has alpha channel of the VkImage, it can help an optimization to disable blending when the texture doesn't have alpha. Because the VkFormat isn't enough because it's always set to VK_FORMAT_B8G8R8A8_SRGB or VK_FORMAT_R8G8B8A8_SRGB.
2022-11-11render/vulkan: always wait for last stage to complete before renderingSimon Ser
When we have multiple command buffers in flight, we need to make sure we don't start rendering before the previous texture uploads are complete.
2022-11-11render/vulkan: use command buffer pool for stageSimon Ser
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.

2022-11-07render/vulkan: use wl_array for wlr_vk_shared_buffer.allocsSimon Ser
Avoids the need to open-code the realloc() logic.
2022-11-07render/vulkan: fix and add missing wl_list commentsSimon Ser
In wlroots we add comments near struct wl_list members to indicate which type it's linked to. The Vulkan renderer had some comments with mistakes, and some members without a comment.
2022-11-04render/vulkan: drop outdated commentsSimon Ser
2022-11-04render/vulkan: remove exts arg from vulkan_instance_create()Simon Ser
2022-11-04render/vulkan: add caching to vulkan_read_pixelsDavid96
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.
2022-09-30render/vulkan: use addon for wlr_vk_textureSimon Ser
Avoids having to walk the list of all textures.
2022-09-30render/vulkan: use addon for wlr_vk_render_bufferSimon Ser
Avoids having to walk the list containing all of the render buffers.
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.
2021-11-17Remove support for DMA-BUF flagsSimon Ser
They are never used in practice, which makes all of our flag handling effectively dead code. Also, APIs such as KMS don't provide a good way to deal with the flags. Let's just fail the DMA-BUF import when clients provide flags.
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.
