Each register has a specified offset within that space, * which is mapped into virtual memory space in ipa_mem_init(). Each * has a unique identifer, taken from the ipa_reg_id enumerated type. * All IPA registers are 32 bits wide. * * Certain "parameterized" register types are duplicated for a number of * instances of something. For example, each IPA endpoint has an set of * registers defining its configuration. The offset to an endpoint's set * of registers is computed based on an "base" offset, plus an endpoint's * ID multiplied and a "stride" value for the register. Similarly, some * registers have an offset that depends on execution environment. In * this case, the stride is multiplied by a member of the gsi_ee_id * enumerated type. * * Each version of IPA implements an array of ipa_reg structures indexed * by register ID. Each entry in the array specifies the base offset and * (for parameterized registers) a non-zero stride value. Not all versions * of IPA define all registers. The offset for a register is returned by * reg_offset() when the register's ipa_reg structure is supplied; * zero is returned for an undefined register (this should never happen). * * Some registers encode multiple fields within them. Each field in * such a register has a unique identifier (from an enumerated type). * The position and width of the fields in a register are defined by * an array of field masks, indexed by field ID. Two functions are * used to access register fields; both take an ipa_reg structure as * argument. To encode a value to be represented in a register field, * the value and field ID are passed to reg_encode(). To extract * a value encoded in a register field, the field ID is passed to * reg_decode(). In addition, for single-bit fields, reg_bit() * can be used to either encode the bit value, or to generate a mask * used to extract the bit value. */ /* enum ipa_reg_id - IPA register IDs */ enum ipa_reg_id { COMP_CFG, CLKON_CFG, ROUTE, SHARED_MEM_SIZE, QSB_MAX_WRITES, QSB_MAX_READS, FILT_ROUT_HASH_EN, /* IPA v4.2 */ FILT_ROUT_HASH_FLUSH, /* Not IPA v4.2 nor IPA v5.0+ */ FILT_ROUT_CACHE_FLUSH, /* IPA v5.0+ */ STATE_AGGR_ACTIVE, IPA_BCR, /* Not IPA v4.5+ */ LOCAL_PKT_PROC_CNTXT, AGGR_FORCE_CLOSE, COUNTER_CFG, /* Not IPA v4.5+ */ IPA_TX_CFG, /* IPA v3.5+ */ FLAVOR_0, /* IPA v3.5+ */ IDLE_INDICATION_CFG, /* IPA v3.5+ */ QTIME_TIMESTAMP_CFG, /* IPA v4.5+ */ TIMERS_XO_CLK_DIV_CFG, /* IPA v4.5+ */ TIMERS_PULSE_GRAN_CFG, /* IPA v4.5+ */ SRC_RSRC_GRP_01_RSRC_TYPE, SRC_RSRC_GRP_23_RSRC_TYPE, SRC_RSRC_GRP_45_RSRC_TYPE, /* Not IPA v3.5+;
