FROMLIST: arm64: dts: qcom: shikra: Remove cdsp compute-cb@9

[Anandu Krishnan E (quic-anane)]

Remove the context bank compute-cb@9 as it is a secure context bank used for secure use cases. Secure use case support is not currently implemented upstream, and allowing other use cases to be offloaded onto this context bank results in an SMMU fault.

Commit	Community Verdict
arm64: dts: qcom: shikra: Remove cdsp compute-cb@9	⏳ Decision Pending — Reviewed-by: Konrad Dybcio on 2026-09-29; no merge confirmation yet

Issues

• Context offset: The PR applies the patch at line 2895, while the lore patch targets line 1948. This is a 947-line difference, indicating the PR's base tree has significantly more content in shikra.dtsi than the upstream tree the lore patch was based on. The code change itself (removing compute-cb@9 node) is identical.
• Vendor metadata: PR adds CRs-Fixed: 4635461 which is not in the lore patch. This is acceptable vendor-specific metadata.

Verdict

The patch content is faithful to the lore source. The subject correctly uses FROMLIST: prefix since the patch has been posted to the mailing list but not yet merged upstream. The commit message body, Fixes tag, and authorship are all correct. The diff shows a large context offset (947 lines) but the actual code change is identical. The patch has received Reviewed-by: from Konrad Dybcio but has not been merged into mainline yet.

Recommendation: Merge with awareness that this is ahead of upstream acceptance. The large context offset suggests the vendor tree has additional content not yet upstream.

Root cause: The Fixes: tag references commit 8b6f81f7801a which is not present in the checked-out tree at the time of validation.

Failure details:

WARNING: Unknown commit id '8b6f81f7801a', maybe rebased or not pulled?
#11: 
Fixes: 8b6f81f7801a ("arm64: dts: qcom: shikra: Add CDSP, LPAICP, MPSS remoteproc PAS nodes")

c28211ce6dab471f7343c1dcde520551af8f95d9 total: 0 errors, 1 warnings, 0 checks, 12 lines checked

Commit c28211ce6dab ("FROMLIST: arm64: dts: qcom: shikra: Remove cdsp compute-cb@9") has style problems, please review.

Analysis:

This is a WARNING (not an ERROR), meaning it's advisory rather than blocking. The warning occurs because checkpatch cannot find commit 8b6f81f7801a in the current git history. This can happen for several reasons:

1. The commit exists in a different branch or remote that wasn't fetched during CI
2. The commit was rebased/rewritten with a different SHA
3. The commit is in the upstream tree but not in the base branch being checked

Fix:

Verify the Fixes tag references the correct commit:

# Search for the commit in the full tree
git log --all --oneline --grep="Add CDSP, LPAICP, MPSS remoteproc PAS nodes" | grep shikra

# If found with a different SHA, update the Fixes tag:
git rebase -i <base_sha>   # mark commit as 'edit'
# Update the commit message with the correct SHA
git commit --amend
git rebase --continue

If the commit truly exists in the target branch history, this warning can be safely ignored as a CI environment limitation (the base tree may not have had all refs fetched).

Reproduce locally:

./scripts/checkpatch.pl --strict --ignore FILE_PATH_CHANGES --git ab439ff21547145a1b6b13bc471f4383ac7e9b66..c28211ce6dab471f7343c1dcde520551af8f95d9

Verdict

1 non-blocking warning to review before merge.

The checkpatch warning about the unknown commit ID in the Fixes: tag should be verified:

• If commit 8b6f81f7801a exists in the target branch, the warning is a false positive due to CI fetch limitations and can be ignored.
• If the commit SHA is incorrect or the commit was rebased, update the Fixes: tag with the correct SHA.

All other checkers passed or were correctly skipped. The patch is otherwise compliant with kernel coding standards and has proper upstream attribution (FROMLIST: prefix + Link: tag).
