synchronization validation failure related to dynamic descriptor set

[cclao]

Describe the Issue
synchronization validation failure related to dynamic descriptor set

Valid Usage ID
This is found with ANGLE. ANGLE is OpenGLES implementation on top of vulkan. We recently implemented buffer sub-allocation from VkBuffer and run into syncval failure. The failure goes away if I disable the use of VK_DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC. My guess is that when dynamic uniform buffer is used, the actual buffer range been used for uniform buffer maybe not been calculated properly, which result in false hazard detection.

Environment:

• OS:
• GPU:
• SDK or header version if building from repo:
• Options enabled (synchronization, best practices, etc.):

sorry for the late reply. @cclao is there any more information about this issue, an api dump or something to help reproduce?

[ianelliottus]

@spencer-lunarg both @mark-lunarg and @mikes-lunarg know how to build ANGLE. I will ask @cclao to coordinate with them.

Hi Spencer, to reproduce, you need to build ANGLE.

1. Remove these lines of code that skip the specific VVL error described here.
   https://chromium.googlesource.com/angle/angle/+/refs/heads/main/src/libANGLE/renderer/vulkan/RendererVk.cpp#406
   to line 424
2. Build and install ANGLE, and run all tests we have. Or the alternative way is try to run in ANGLE CI bots and some tests will fail and you can start from that.
   There are more information in this bug as well

@cclao I commented out the 4 errors from the file (under http://anglebug.com/6725) and built ANGLE (release, hope that wouldn't matter) and ran

angle/out/Release/bin$ ./run_angle_deqp_gles31_tests --use-angle=swiftshader --gtest_filter=functional.draw_indirect.compute_interop.separate.* --verbose --local-output --verbose-logging

and it passed the tests, am I missing something obvious here?

@spencer-lunarg, DM'd you some hints.
