From: Animesh Manna <[email protected]> For dgfx, DSB should use local memory instead of system memory. Using local memory surely brings performance improvement as local memory is close to gpu. Also want to avoid multiple gpu using system memory.
Use LMEM API to create gem object needed for DSB command buffer.
