- 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.

# Device profile: Xiaomi, Snapdragon 8 Elite (Adreno 830), adb serial 35d0befa.
|
|
#
|
|
# One of the two devices the disaggregation campaign is measured on (the other is
|
|
# devices/oppo-mali.env). It exists so that the pinning and thermal protocol the campaign
|
|
# actually runs is written down in the repository instead of living in one operator's shell
|
|
# history, and so that a `--device` argument names something reviewable.
|
|
#
|
|
# ============================ NOT YET DEVICE-VERIFIED ============================
|
|
# PROFILE_VERIFIED=0 below, and bench.sh / session.sh / profile.sh REFUSE to run against a
|
|
# profile that says so unless --allow-unverified-profile is passed. Two of the values here are
|
|
# protocol constants that are known (the campaign pins big 1.96 GHz / little 1.55 GHz and gates
|
|
# at 40 C), but the sysfs node names and the exact available OPPs are NOT: this is a Qualcomm
|
|
# part and the harness was written against MediaTek, where the pin goes through
|
|
# /proc/ppm/policy/hard_userlimit_* and the GPU through /proc/gpufreq/gpufreq_opp_freq. Neither
|
|
# path exists on this SoC - Adreno pins through /sys/class/kgsl/kgsl-3d0/devfreq/{min,max}_freq
|
|
# and its cpufreq policies are not policy6/policy0.
|
|
#
|
|
# A profile that quietly wrote MediaTek paths on this device would be the worst outcome
|
|
# available: `su -c 'echo ... > /proc/ppm/...'` fails silently, bench.sh would report a run it
|
|
# believes was pinned, and the pin-integrity fields it samples at window end would be the only
|
|
# clue. So the unknown fields are left EMPTY and marked, rather than guessed, and the refusal is
|
|
# the mechanism that keeps them from being used before somebody has read them off the device.
|
|
#
|
|
# To promote this profile: fill in the four TODO fields from the device
|
|
# (`cat /sys/devices/system/cpu/cpufreq/policy*/scaling_available_frequencies`,
|
|
# `ls /sys/class/kgsl/kgsl-3d0/devfreq/`, `for tz in /sys/class/thermal/thermal_zone*; do
|
|
# echo "$tz $(cat $tz/type)"; done`), teach bench.sh the Qualcomm pin path, run one pinned
|
|
# window, check big_cur/little_cur/gpu_cur_khz in the result JSON against the pins, and only
|
|
# then set PROFILE_VERIFIED=1 in the same commit as the bench.sh change.
