Hi all, Sorry for the bunch of emails, I'm working on some new stuff and running into issues. For CONFIG_BOOKE it appears that DBCR0_ACTIVE_EVENTS includes DBCR0_ICMP but not DBCR0_BRT. Is that just because none of the code paths currently using DBCR0_ACTIVE_EVENTS need to check DBCR0_BT? Also, in sys_debug_setcontext() why does SIG_DBG_BRANCH_TRACING return -EINVAL if CONFIG_PPC_ADV_DEBUG_REGS is set? Would it not be possible to use DBCR0_BRT?
