+## Notes
+
+Currently, there is no lower-level GPU IR like NVVM available for the Intel GPU compiler toolchain. XeGPU dialect uses LLVM or SPIRV intrinsic to access advanced intel GPU instructions. When the lower-level software changes, we expect XeGPU lowering passes to change accordingly.  


For people not familar with NVVM, it may be better to give more detail on how the low level dialect looks like.
"GPU IR like NVVM available for the Intel GPU compiler toolchain" ->
"dialect for the Intel GPU compiler tool chain to represent GPU ops with values based on LLVM data types such as NVVM dialect for the Nvidia GPU compiler toolchain"
