- bench.sh's pin_freqs writes /proc/ppm and /proc/gpufreq, which exist on neither 35d0befa
(SM8750) nor 3B159D009VZ00000 (MT6993 dropped both for /proc/gpufreqv2); the guard the
PROFILE_VERIFIED key exists for was about to be defeated on the device its own comment
guessed was safe
- pin_device.sh pins big/little/GPU through the nodes each device actually has (Xiaomi:
policy6 1958400 / policy0 1555200 / kgsl pwrlevel 0; Oppo: policy4 2000000 + policy7
2000000 / policy0 1600000 / gpufreqv2 fix_target_opp_index 0), checks only against its own
pins because ColorOS moves stock maxima by itself, and refuses to call a zero-key read a verdict
- both profiles are PROFILE_VERIFIED=1 on 30 s pinned windows with zero drift; the evidence and
the two things not verified (Oppo GPU held at DVFS-request level only, no full bench window)
are in docs/Disaggregated/devices/pin-verification-2026-09-07.md
- format_benchmark printed a p50 taken with the nearest-rank rule beside a medianFrameCpuMs the
device computes as the average of the two middle frames, and documented the two as one rule; on
an even window they differ (the pre-flight printed p50=8.261ms next to medianCpuMs=271.766).
p50 now goes through series_median, which is SummarizeSeries' rule transcribed; p95 and p99 stay
nearest rank, which is the device's rule for p95 and the honest extension of it for the p99 the
device does not compute at all
- require_verified_profile treated a profile that simply omits PROFILE_VERIFIED as verified, which
is the fail-open default a profile written by copying another one inherits - exactly the case the
guard exists for. It defaults to unverified now, odinlite.env carries PROFILE_VERIFIED=1
explicitly (it is the one profile that earned it), and the refusal says "says 0, or says nothing"
- the two new profiles claimed profile.sh refuses an unverified profile; it has no such check and
needs none - it records a simpleperf profile and pins nothing. The claim is corrected in both
profiles and in the README rather than a guard added where there is nothing to guard
- the handle-ABA / CSO control step in test.yml set only MOBILEGL_ITEST_REQUIRE_GPU while its
sibling verify step sets the three MOBILEGL_MAGMA_* fixes and arms core dumps. It runs the same
DirectVulkan binary on the same runner, so a crash there left no core; it now carries both
- DriverBenchStateToggle runs mc_state_toggle as its own ctest entry. The case has been in
kBenchCases since P0 and nothing executed it, so nothing would have noticed it rotting - and it
is the exact enable/draw/disable/draw shape the microbenchmark P2 owes the GO/NO-GO measures.
About 1.2 s inside an existing three-minute job.
- scripts/g7_negative_control.sh breaks the pipeline/dynamic split on purpose: it inserts two
boundaries so ColorMasks becomes a dynamic chunk of its own, which keeps the partition sorted,
non-overlapping and complete - so it still COMPILES - while making glColorMask bump
m_pipelineStateVersion without moving the pipeline-subset hash. A non-zero ctest is the pass.
- Everything that could make that control lie is refused rather than reported: a missing
SetterConsistency test exits 2 instead of reading "no tests matched" as a failure; a tree that
is already red or already broken exits 2; a patched table that does not compile exits 2, since
a build break would prove the static_asserts work rather than that the test still checks; and
the restore is from byte-for-byte copies (never from git, so a dirty tree is given back
intact), followed by a rebuild and a re-run that must be green. --verify-patch-only exercises
the mechanism where the test does not exist yet and says explicitly that it is not a pass.
- Profiles for the two campaign devices, and the guard that stops them being trusted early. Both
carry PROFILE_VERIFIED=0 and every device-specific field is TODO_VERIFY_ON_DEVICE rather than a
guess: the harness pins through MediaTek nodes and 35d0befa is a Qualcomm part, where
`su -c 'echo ... > /proc/ppm/...'` fails with a zero exit and the run would report numbers it
believes were pinned. bench.sh and session.sh now refuse an unverified profile unless
--allow-unverified-profile is passed, which warns that the run is not comparable with a pinned
one. The README records what earns PROFILE_VERIFIED=1.
