[maksimsab]

This patch has the following changes:

• --param enable_new_offload_model is added to SYCL E2E LIT test configuration
• NewOffloadModel mode run is added to sycl-linux-precommit
• NewOffloadModel mode run is added to sycl-nightly for linux and windows.

Hi @sarnex

Could you please help with reviewing this change or recommend somebody for that?

[sarnex]

I can review, thanks

[sarnex]

High level question, do we think changes that break the new offload model but nothing else are common enough to justify precommit testing? Last I heard we were only going to do nightly testing

[maksimsab]

I was also considering that aspect. To being able to check E2E tests for changes related to new model we need either precommit functionality or some workflow other that sycl-nightly that we would run manually every time in PR. Perhaps, we could introduce some PR label "new-offload-model" that could enable this branch in precommit.

I'm happy to have it in pre or postcommit if you guys ( @YuriPlyakhin / @intel/dpcpp-tools-reviewers ) think there is a decent likelihood that some PR passes all other CI but fails on the new offload model. If we think that is pretty rare I would recommend we do nightly-only testing, if you want to manually test new offload stuff in a PR you can run the nightly explicitly though the github UI

If you decide to go with the label, then

llvm/.github/workflows/sycl-linux-precommit.yml

Lines 239 to 248 in 26e4c60

	test-perf:
	needs: [build, detect_changes]
	permissions:
	contents: write
	packages: read
	if: |
	!cancelled()
	&& needs.build.outputs.build_conclusion == 'success'
	&& (contains(github.event.pull_request.labels.*.name, 'run-perf-tests')
	|| contains(needs.detect_changes.outputs.filters, 'perf-tests'))

might be useful to look at. I don't remember why I decided to keep that as a separate job instead of extending regular matrix though.

permissions:
contents: write
packages: read

should work hopefully

[maksimsab]

llvm/.github/workflows/sycl-windows-run-tests.yml

Line 80 in 26e4c60

permissions: read-all

For some reason, sycl-windows-run-tests.yml requires many permissions.

[sarnex]

I think we just didn't restrict the permissions on that one, did you try restricting them and it failed?

[sarnex]

Also you might want to rebase this PR against HEAD if you're going to run the nightly, I merged a fix today that should fix the AOT failures, they're unrelated to this PR.
