❌ check-uapi-headers

Root cause: Docker image kmake-image:latest unavailable in CI environment — infrastructure issue, not a patch defect.

Failure details:

Unable to find image 'kmake-image:latest' locally
docker: Error response from daemon: pull access denied for kmake-image, 
  repository does not exist or may require 'docker login': denied: 
  requested access to the resource is denied
cat: uapi_errors.log: No such file or directory
##[error]Process completed with exit code 1.

Analysis:
The check-uapi-headers checker requires the kmake-image Docker container to build the kernel and compare UAPI headers. The CI runner could not pull this image, causing the checker to fail before it could analyze the PR changes. This PR modifies only drivers/media/platform/qcom/iris/ C files — no UAPI headers, sysfs attributes, or module parameters are changed, so the checker would have skipped or passed if the Docker image were available.

Fix: Re-trigger CI after verifying Docker registry access. No patch changes needed.

Reproduce locally:
Not applicable — this is a CI infrastructure issue. If you want to verify UAPI compliance manually:

./scripts/check-uapi.sh -b 3f28a0821dae422e2a380a83c1c5d855480a80c0 \
  -p a350298f0289b9a14c416c20ade1b60ffabf3c11 -l uapi_errors.log

---

❌ check-patch-compliance

Root cause: b4 tool unable to fetch upstream patches from lore.kernel.org — network connectivity or lore archive issue, not a patch defect.

Analysis:
All 4 commits have:

• ✅ Valid BACKPORT: prefix (required for backported patches)
• ✅ Valid Link: trailer pointing to lore.kernel.org
• ✅ Proper lore message-ID format

The checker failed because b4 am could not fetch the patches from lore.kernel.org. This indicates either:

1. Network connectivity issue in the CI environment
2. The lore archive doesn't have these messages yet (patches may be very recent or not yet archived)
3. Transient lore.kernel.org service issue

The Link URLs are correctly formatted and point to a valid v7 patch series (20260512-batch2_features-v7-{1,2,3,4}). The commits are properly attributed with Signed-off-by, Reviewed-by, Tested-by, and upstream maintainer sign-off.

Fix: Re-trigger CI. If the issue persists, verify the patches are archived on lore.kernel.org by visiting the URLs in a browser. No patch changes needed — the commit metadata is correct.

Reproduce locally:

# Test b4 fetch for each commit:
b4 am --single-message -C -l -3 \
  https://lore.kernel.org/linux-arm-msm/20260512-batch2_features-v7-1-4954e3b4df84@oss.qualcomm.com/

# If b4 succeeds, compare the fetched patch to the PR commit:
git format-patch -1 <commit-sha> --stdout > /tmp/pr-commit.patch
diff <(awk '/^diff/,/^--$/' /tmp/pr-commit.patch | grep -E '^[+-][^+-]') \
     <(awk '/^diff/,/^--$/' /tmp/out/*.mbx | grep -E '^[+-][^+-]')

---

✅ tag-check (manual verification)

Status: PASS

Analysis:
The PR targets a branch other than qcom-next or qcom-next-staging (confirmed by CI logs showing non-qcom-next-staging path), so every commit must have a subject-line prefix tag.

All 4 commits have the BACKPORT: prefix:

1. BACKPORT: media: qcom: iris: Add intra refresh support for gen1 encoder
2. BACKPORT: media: qcom: iris: Add Long-Term Reference support for encoder
3. BACKPORT: media: qcom: iris: Add B frames support for encoder
4. BACKPORT: media: qcom: iris: Add hierarchical coding support for encoder

BACKPORT: is a valid prefix for upstream patches that have been backported with modifications. ✅

---

Verdict

2 CI infrastructure failures; 0 patch defects.

The PR is ready to merge from a code quality perspective. Both failures are CI environment issues:

1. check-uapi-headers — Docker image unavailable (infrastructure)
2. check-patch-compliance — b4 unable to fetch from lore.kernel.org (network/archive)

All code-level checkers passed:

• ✅ checkpatch (no style issues)
• ✅ sparse-check (no static analysis warnings)
• ✅ tag-check (all commits have valid BACKPORT: prefix)

Recommended action: Re-trigger CI. If check-patch-compliance continues to fail, manually verify the lore.kernel.org URLs are accessible and the patches match the PR commits.

WangaoW Sorry to hijack this thread. I noticed that the encoder implementation in the downstream video-driver references V4L2_MPEG_VIDEO_HEVC_PROFILE_MAIN_10, but it is not yet present in the upstream Iris driver.

The 10-bit decoding was supported recently. Are there any plans to upstream support for 10-bit encoding (HEVC Main10 / P010) to the new Iris driver? This is very useful for HDR10 encoding use cases.

Yes, we do plan to support HDR10 for encode as well. Immediate plan is to support ROI (patches posted), followed by HDR10+ decode. Next would be HDR10 encode.
Incase you do have any proposal to enable (HDR10 encode) the same at your end, please post the same for reviews. HDR10 encode is indeed very useful and needed feature.

vgarodia Thank you for the reply. Based on my overview of the downstream video-driver, not every platform supports 10-bit encoding (I am unsure whether this is due to hardware limitations or a lack of implementation in the firmware). It would be great to have a feature matrix placed somewhere documenting VPU support for 10-bit encoding and similar codec specs across the various platforms. For example, something like https://developer.nvidia.com/video-encode-decode-support-matrix

My primary use case is FFmpeg, including patching it to use 10-bit support when necessary. I am currently running on the QCS6490 and SC8280XP, and might be able to test on the X1E in the future.
