I had to google the subject to find what e-mail you were talking about -- it was posted a year ago: http://marc.info/?l=linuxppc-embedded&m=136572252330650&w=2 Next time please quote the e-mail if you're trying to revive a thread, and keep the original poster on CC. I've quoted it here: > 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? Perhaps it was just an oversight. I've CCed Dave Kleikamp and Torez Smith, who added DBCR0_ACTIVE_EVENTS. > Also, in sys_debug_setcontext() why does SIG_DBG_BRANCH_TRACING return > -EINVAL if CONFIG_PPC_ADV_DEBUG_REGS is set?

Either nobody has gotten around to implementing it, or the semantics are different in some way (if the semantics are even defined anywhere -- I couldn't find any documentation). -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
