You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.

@hongxiayang after merging this PR, is there any plan to expedite the checking of existing AITER kernels and fixes for them to work on this new AITER commit? and especially the MLA V1.

For documentation purposes: I have quoted the AITER commit mentioned in previous PR (#17864)
AITER commit used here is : c1debd87ce0391aa27438d9e07e76e4fea7c4b70

I'm able to run deepseekV2-lite-chat on NVIDIA GPUs in V0 mode on this branch. So we just need to verify AMD side.

Validated the PR, it works.

Moreover, at this point in time, the integrated AITER kernels are working with this new AITER commit. The ones that have issues in new AITER commits are:

• HipLoad fmoe_fp8_g1u1_subGU_512_silu_tkw1.co
• AITER MLA V1

Looks good.
