…net#25643) * [build] Add build timing report and dependency analysis tools Add three scripts for build performance instrumentation: - scripts/build-timing-report.sh: Parse per-package timing from build logs (HEADER/FOOTER timestamps), generate sorted duration table, phase breakdown, parallelism timeline, and CSV export. - scripts/build-dep-graph.py: Parse rules/*.mk dependency graph, compute critical path, fan-out/fan-in bottleneck analysis, and generate DOT/JSON output for visualization. - scripts/build-resource-monitor.sh: Sample CPU, memory, disk I/O, and Docker container count during builds for resource utilization analysis. Add "make build-report" target to slave.mk that runs the timing report and dependency analysis after a build completes. Example output from a VS build on 24-core/30GB machine: - 210 packages built in 53m wall time (173m CPU) - Max concurrency: 5 (with SONIC_CONFIG_BUILD_JOBS=4) - Critical path: 14 packages deep (libnl -> libswsscommon -> utilities) - Top bottleneck: LIBSWSSCOMMON with 48 downstream dependents Signed-off-by: Rustiqly <[email protected]> * Address Copilot review: fix 17 bugs in build analysis scripts - Use free -m with division instead of free -g to avoid rounding (#1) - Add = and ?= to Makefile dependency regex patterns (sonic-net#2, sonic-net#7) - CPU calculation now uses /proc/stat delta (two reads) (sonic-net#3, sonic-net#14) - Fix misleading 'critical path estimate' comment (sonic-net#4) - Fix parallelism timeline comment (60s not 10s) (sonic-net#5) - Include after-relationship packages in fan stats (sonic-net#6) - Guard disk I/O division by zero when INTERVAL<=1 (sonic-net#8) - Remove unused elapsed_line variable (sonic-net#9) - Remove redundant LIBSWSSCOMMON_DBG check (sonic-net#10) - Remove active_make_jobs from CSV header comment (sonic-net#11) - Wire up _RDEPENDS parsing to build reverse deps (sonic-net#12) - Remove unnecessary 'if v' filter on rdeps JSON (sonic-net#13) - Remove unused REPORT_FORMAT parameter (sonic-net#15) - Add cycle detection to critical path algorithm (sonic-net#16) - Add execute permission check for companion scripts (sonic-net#17) Signed-off-by: Rustiqly <[email protected]> --------- Signed-off-by: Rustiqly <[email protected]> Co-authored-by: Rustiqly <[email protected]>
