  42. # Shipment builds (user variants) should not have any debug feature
  43. # enabled. This is identified using 'TARGET_BUILD_VARIANT'. Slub builds
  44. # are identified using the CONFIG_SLUB_DEBUG_ON configuration. Since
  45. # there is no other way to identify defconfig builds, QTI internal
  46. # representation of perf builds (identified using the string 'perf'),
  47. # is used to identify if the build is a slub or defconfig one. This
  48. # way no critical debug feature will be enabled for perf and shipment
  49. # builds. Other OEMs are also protected using the TARGET_BUILD_VARIANT
  50. # config.
