    • Vulkan: optimize image memory barriers · 7dafe3eb
      Shahbaz Youssefi authored 
      Each image was tracking its current layout, but not the pipeline stage
it was used.  Additionally, the barrier access masks were inferred from
the layout.  This incurred two inefficiencies:

- The src pipeline stage mask often included all stages, causing
  unnecessarily heavy barriers.
- The access masks included all possible accesses by a layout, which in
  some cases was overkill, like VK_ACCESS_MEMORY_WRITE_BIT for
  VK_IMAGE_LAYOUT_GENERAL (which will eventually used for compute shader
  output).

This change instead creates an enum where each element represents the
layout, the stage and access masks when transitioning into the layout
and the stage and access masks when transitioning out of that layout.
The image will instead track a value of this enum (instead of
VkImageLayout), which allows it to create the layout transition barriers
as tight as possible, since it includes all the necessary information.

    • Vulkan: Implement GLsync and EGLSync fence syncs · 82fddcb1
      Shahbaz Youssefi authored 
      That is required in GLES 3 for GLsync and EGL_KHR_fence_sync and
EGL_KHR_wait_sync (or EGL 1.5) for EGLSync.

The two constructs (GLsync and EGLSync) have similar semantics and share
the implementation on the Vulkan backend.

The implementation of a fence sync object is achieved through the
combined use of a vkEvent and the implicit vkFence inserted at the end
of every submission.  Imagine the following command buffer:

    glDraw      : Draw
    glCreateSync: Set Event  <-- insertion of fence sync
    glDraw      : Draw
                : Signal Fence <-- implicit fence at the end of submission
    glFlush     : Submit

Assume the serial S is associated to this submission.  The following
hold:

- If event is set, the fence sync is signaled
- If S is already finished, the fence sync is signaled
- If client is waiting on the sync and S is not yet flushed, there will
  be a deadlock (unless multi-threaded and another thread performs the
  flush).

The event is used to implement server waits (glWaitSync), as vkEvent is
the only entity the GPU can signal and wait on within the command
buffer.  The wait is inserted in the command graph without incurring a
flush, i.e. the wait can be within the same command buffer as event set.

The event however does not support CPU waits (glClientWaitSync).
vkFence is the only entity the CPU can wait on.  For client wait
therefore, the following algorithm is used:

- If the event is already set, there's no wait  ->  already signaled
- If timeout is zero, there's no wait  ->  timeout expired
- If S is not flushed, flush it to ensure forward progress.
- Wait until S is finished  ->  condition satisfied / timeout expired.

    • Vulkan: Use glslang's internal BUILD.gn. · 0cb3b0f1
      Jamie Madill authored 
      This retires the ANGLE BUILD.gn file for glslang. Also makes a few more
repos sync from Chromium's copy using build overrides. This should
speed up Chrome checkouts slightly.
