| # As per target team, build is done as follows: |

| # CONFIG_SLUB_DEBUG_ON := y + CONFIG_PAGE_POISONING := y |
| # 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. |
