From 8456ac6fa9dadadca0b69ee0a0b02e60fbd45427 Mon Sep 17 00:00:00 2001 From: Simon Ser Date: Fri, 2 Dec 2022 19:15:16 +0100 Subject: render/vulkan: wait for DMA-BUF fences 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. --- include/render/vulkan.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'include/render') diff --git a/include/render/vulkan.h b/include/render/vulkan.h index 42b79bbd..66739c40 100644 --- a/include/render/vulkan.h +++ b/include/render/vulkan.h @@ -49,6 +49,7 @@ struct wlr_vk_device { PFN_vkWaitSemaphoresKHR waitSemaphoresKHR; PFN_vkGetSemaphoreCounterValueKHR getSemaphoreCounterValueKHR; PFN_vkGetSemaphoreFdKHR getSemaphoreFdKHR; + PFN_vkImportSemaphoreFdKHR importSemaphoreFdKHR; } api; uint32_t format_prop_count; @@ -280,6 +281,8 @@ struct wlr_vk_texture { // If imported from a wlr_buffer struct wlr_buffer *buffer; struct wlr_addon buffer_addon; + // For DMA-BUF implicit sync interop + VkSemaphore foreign_semaphores[WLR_DMABUF_MAX_PLANES]; }; struct wlr_vk_texture *vulkan_get_texture(struct wlr_texture *wlr_texture); -- cgit v1.2.3
