# Defconfig : build with default flags

# Perf      : Using appropriate msmXXXX-perf_defconfig

#

# Shipment builds (user variants) should not have any debug feature

# enabled. This is identified using 'TARGET_BUILD_VARIANT'. Slub builds

# are identified using the CONFIG_SLUB_DEBUG_ON configuration. Since

# there is no other way to identify defconfig builds, QTI internal

# representation of perf builds (identified using the string 'perf'),

# is used to identify if the build is a slub or defconfig one. This

# way no critical debug feature will be enabled for perf and shipment

# builds. Other OEMs are also protected using the TARGET_BUILD_VARIANT

# config.
