Revert "Vulkan:Optimize SecondaryCommandBuffers" This reverts commit 2219b18c984ed69251f3db3c7b5fd69a2fa68c77. Reason for revert: Failing to compile on ASAN builders: https://ci.chromium.org/p/chromium/builders/try/linux-libfuzzer-asan-rel/134782 Currently blocking roll. Original change's description: > Vulkan:Optimize SecondaryCommandBuffers > > Optimize performance of SecondaryCommandBuffers and enable them as the > default build option. > To disable this set angle_enable_custom_vulkan_cmd_buffers=false in > your build args. > > This CL enhances the PoolAllocator to have a "fast" mode that can > be enabled at class creation. This mode uses an alignment of 1 byte and > enables a fastAllocation() call that avoids some bookkeeping overhead. > The SecondaryCommandBuffer uses this fastAllocation() function. > Furthermore the fast path of fast allocate, using the current page, > is inlined for maximum speed. > Jamie Madill also updated the SecondaryCommandBuffers to pre-allocate > blocks so that the commands occur linearly in memory. This speeds up > processing with improved cache coherency and minimizes overhead when > recording commands. > Also the core Draw functions and their state updates are all inlined > as well as the common functions to initialize commands and to copy > command pointer data. > > This change also includes some new, custom commands. One is > imageBarrier that is a specialized version of pipelineBarrier that only > performs a single image layout transition. > There are customized versions of various Draw commands to minimize > copying of parameters. > There are also specialized commands to bind[Graphics|Compute]Pipeline > that have the pipeline type built in to the command. > More custom commands and command data size optimizations will be made > in follow-on commits. > > Bug: angleproject:3136 > Change-Id: I35453cc2656bc8c51f0d84d1adef106900aca9a5 > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1497418 > Commit-Queue: Tobin Ehlis <tobine@google.com> > Reviewed-by: Jamie Madill <jmadill@chromium.org> TBR=tobine@google.com,syoussefi@chromium.org,jmadill@chromium.org Change-Id: I1c0bfe864ff343eb8ea6c88556523f8715c981d5 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: angleproject:3136 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1535998 Reviewed-by: Jamie Madill <jmadill@chromium.org> Commit-Queue: Jamie Madill <jmadill@chromium.org>
