[EXP][usm p2p] Add test for ur_exp_usm_p2p and impl for hip #1369

JackAKirk · 2024-02-21T17:32:15Z

Adds USM_P2P impl for hip backend.
Introduces UR_USM_P2P_EXTENSION_STRING_EXP macro to the spec which is used to check for usm_p2p experimental extension support in UR.
The existing supported backend for this extension (CUDA) now correctly returns this device value string.
This device value string is used in the new test that is introduced to check the basic extension behavior for all implementations.

This PR matches the precedent set in #1089 for experimental extension conformance testing.

Uses the latest non deprecated hip APIs. fully tested and passing via DPC++ using Crusher. Signed-off-by: JackAKirk <[email protected]>

I'd replace one of the twowhichs with that.

Minor change to above that you may simply ignore

Programming models like SYCL or OpenMP aim to support several important projects that utilise fine-grained peer-to-peer memory access controls. This experimental extension to the Unified-Runtime API aims to offer a portable interface capable of invoking relevant driver functions to query about and control peer memory access across various adapters, including CUDA, HIP, and Level Zero.

I'll switch the first sentence, I think this is an improvement. I think the second one is not as good as the original though.

not sure if that should be revision 2.0?

I'm following other extensions that iterate through 1.1,1.2 etc. This is a minor change to the spec.

Please merge in the main branch so we have up to date test runs, it should also have an intel/llvm PR for testing.

I didn't add a intel/llvm PR for testing here because it doesn't affect any intel/llvm code at all. The only code anywhere that this uses is in the test that is added.
I can merge ur if you want but FYI the situation here is basically the same: no existing tests are affected by the code change.
