[SYCL][Graph] L0 Backend support for SYCL Graphs (2/4) by Bensuo · Pull Request #9992 · intel/llvm

Level Zero Backend Support for SYCL Graphs

This is the second patch of a series that adds support for an experimental command graph extension

A snapshot of the complete work can be seen in draft PR #9375 which has support all the specification defined ways of
adding nodes and edges to the graph, including both Explicit and Record & Replay graph construction. The two types of nodes currently implemented are kernel execution and memcpy commands.

See https://github.com/reble/llvm#implementation-status for the status of our total work.

Scope

This second patch focuses on the required PI/UR support for the experimental command-buffer feature in the Level Zero adapter:

PI stubs for all adapters to enable compilation, no functionality.
Command-buffer implementation for the Level Zero UR adapter.
Stubs for the CUDA UR adapter to enable compilation, no functionality.

Following Split PRs

Future follow-up PRs with the remainder of our work on the extension will include:

Hooking up backend to graphs runtime, bugfixes and other feature additions, will add symbols but not break the ABI. (3/4)
Add end-to-end tests for SYCL Graph extension. (4/4)
NFC changes - Design doc and codeowner update.

I didn't go deep into the code, so just some style comments.

Hi @bso-intel, would you be able to review this on behalf of @intel/llvm-reviewers-runtime.

Could someone from @intel/dpcpp-esimd-reviewers please also review this PR.
