    • Vulkan: Don't detach separable shaders in Program::detachShader() · 4db77367
      Tim Van Patten authored 
      To support Program Pipeline Objects, we need to hold on to the shaders
in separable programs, rather than detaching them during
glDetachShader()/glCreateShaderProgramv(). This is necessary due to
requiring the shader information for validating shader interfaces,
varyings, etc.

Instead, a new ShaderMap of bools will be stored in
ProgramState::mAttachedShadersMarkedForDetach to track when a caller
attempts to detach a shader from a separable Program. Later, when a new
shader is attached, we will first validate that the old shader is marked
to be detached, and if so, release it then.

    • Vulkan: Enable CPU only buffers for PBOs · 745e0712
      Mohan Maiya authored 
      Add support for a CPU only buffer for PBOs that serve as
the destination for all host operations like MapBuffer*.
This removes the latency caused by waiting for the in-flight
GPU commands to be complete before handing over the buffer
to the app.

This change removes a ~6ms wait/sleep on the first call to
MapBuffer* in each frame of Manhattan
