Initially all the generated code was per generation. Eventually we grouped it into a single file to reuse as much as possible equation code (this reduce binary size by a factor). So many equations are just the same from generation to generation. But this generated file is 200k lines long... This change puts all the equations into a single file, so that we reuse as much code as possible, and then breaks down the metric sets & register configurations into per generation files. v2: Split registers away from the metric set descriptions Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> --- lib/i915/perf-configs/codegen.py | 320 ++++++++ lib/i915/perf-configs/perf-codegen.py | 716 ------------------ .../perf-configs/perf-equations-codegen.py | 289 +++++++ .../perf-configs/perf-metricset-codegen.py | 238 ++++++ .../perf-configs/perf-registers-codegen.py | 159 ++++ lib/i915/perf.c | 18 +- lib/meson.build | 33 +- 7 files changed, 1053 insertions(+), 720 deletions(-) delete mode 100755 lib/i915/perf-configs/perf-codegen.py create mode 100644 lib/i915/perf-configs/perf-equations-codegen.py create mode 100644 lib/i915/perf-configs/perf-metricset-codegen.py create mode 100644 lib/i915/perf-configs/perf-registers-codegen.py
