This is used to debug crashes that can happen during boot-time. The expected format of a bootconfig is as follows:- dcc_config { link_list_0 { qcom-curr-link-list = qcom-link-list =
, } } Example: dcc_config { link_list_0 { qcom-curr-link-list = 6 qcom-link-list = R_0x1781005c_1_apb, R_0x1782005c_1_apb } link_list_1 { qcom-curr-link-list = 5 qcom-link-list = R_0x1784005c_1_apb } } 2.QAD QAD can be enabled as a part of debugfs file under each individual list folder. QAD is used to specify the access control for DCC configurations, on enabling it the access control to dcc configuration space is restricted. 3.CTI-trigger CTI trigger is used to enable the Cross trigger interface for DCC. On enabling CTI trigger the dcc software trigger can be done by writing to CTI trig-out. Also the hwtrigger debugfs file is created which needs to be disabled for enabling CTI-trigger.
