From d3b8c489a11b92e9d67019c3764a3f51b3f7a6f6 Mon Sep 17 00:00:00 2001 From: Peng Huang Date: Wed, 18 Jan 2023 14:40:07 +0000 Subject: [PATCH] Merge two queue submissions in Queue::SubmitImpl() Currently Queue::SubmitImpl() may cause two queue submissions, one is because of Tick() call which will submit pending commands if there are. The other one is after converting frontend commands to backend command buffer. Queue::SubmitImpl() will submit converted commands. However usually queue submissions are expensive, so merge those two queue submissions into one by not calling Tick() before converting frontend commands, so pending commands and recorded commands can be submitted together. After that, we call Tick() to resolve callbacks and perform bookkeeping operations (deallocating memory for passed operations, etc).
