Stack from ghstack (oldest at bottom):

This adds fine-grained ET_EVENT_TRACER profiling blocks to the Vulkan backend's execute() method in VulkanBackend.cpp. Previously, only GPU shader timestamps were logged. Now the following phases are individually traced: ETVK_COPY_INPUTS (host-to-GPU input transfer), ETVK_RESIZE (graph resize propagation), ETVK_COMPUTE_GRAPH_EXECUTE (GPU compute dispatch), ETVK_COPY_OUTPUTS (GPU-to-host output transfer), and ETVK_EXECUTE (overall delegate execution). The GPU shader timestamp extraction is also moved to occur right after execute() completes rather than at the end of the function, so it falls within the ETVK_EXECUTE span.

[ET-VK][profiling] Add additional profiling blocks
b3e835e 
Pull Request resolved: #17394

This adds fine-grained ET_EVENT_TRACER profiling blocks to the Vulkan backend's execute() method in VulkanBackend.cpp. Previously, only GPU shader timestamps were logged. Now the following phases are individually traced: ETVK_COPY_INPUTS (host-to-GPU input transfer), ETVK_RESIZE (graph resize propagation), ETVK_COMPUTE_GRAPH_EXECUTE (GPU compute dispatch), ETVK_COPY_OUTPUTS (GPU-to-host output transfer), and ETVK_EXECUTE (overall delegate execution). The GPU shader timestamp extraction is also moved to occur right after execute() completes rather than at the end of the function, so it falls within the ETVK_EXECUTE span.
