Matthew Waters	640a65bf96	gst: don't use volatile to mean atomic ... volatile is not sufficient to provide atomic guarantees and real atomics should be used instead. GCC 11 has started warning about using volatile with atomic operations. https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1719 Discovered in https://gitlab.freedesktop.org/gstreamer/gst-plugins-good/-/issues/868 Part-of: <https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/2098>	2021-03-22 14:34:36 +11:00

Matthew Waters	24d096597b	vulkan: implement caching and reuse of a couple of vulkan resources ... Includes a new GstVulkanHandlePool base class for pooling different resources togther. The descriptor cache object is ported to GstVulkanHandlePool with the exact same functionality. A new GstVulkanFenceCache is also implemented for caching fences which is used internally by GstVulkanDevice for creating or reusing fences. The existing GstVulkanTrashFenceList object now caches trash objects.	2019-11-28 23:27:21 +00:00
Matthew Waters	32b3387ae6	vulkan: implement proper descriptor set handling ... The major functionality gain this provides is proper reference counting for a descriptor set. Overall this allows us to create descriptor sets when they are needed (or reused from a cache) without violating any of vulkan's object synchronisation requirements. As there are a fixed number of sets available in a pool, the number of descriptors in elements is currently hardcoded to 32. This can be extended in a future change to create pools on the fly if that limit is ever overrun.	2019-11-07 20:01:57 +00:00
