  28. # enabled. This is identified using 'TARGET_BUILD_VARIANT'. Slub builds
  29. # are identified using the CONFIG_SLUB_DEBUG_ON configuration. Since
  30. # there is no other way to identify defconfig builds, QTI internal
  31. # representation of perf builds (identified using the string 'perf'),
  32. # is used to identify if the build is a slub or defconfig one. This
  33. # way no critical debug feature will be enabled for perf and shipment
  34. # builds. Other OEMs are also protected using the TARGET_BUILD_VARIANT
  35. # config.
