The offset of each register within that space is specified 20 * by symbols defined below. The address space is mapped to virtual memory 21 * space in ipa_mem_init(). All IPA registers are 32 bits wide. 22 * 23 * Certain register types are duplicated for a number of instances of 24 * something. For example, each IPA endpoint has an set of registers 25 * defining its configuration. The offset to an endpoint's set of registers 26 * is computed based on an "base" offset, plus an endpoint's ID multiplied 27 * and a "stride" value for the register. For such registers, the offset is 28 * computed by a function-like macro that takes a parameter used in the 29 * computation. 30 * 31 * Some register offsets depend on execution environment. For these an "ee" 32 * parameter is supplied to the offset macro. The "ee" value is a member of 33 * the gsi_ee enumerated type. 34 * 35 * The offset of a register dependent on endpoint ID is computed by a macro 36 * that is supplied a parameter "ep", "txep", or "rxep". A register with an 37 * "ep" parameter is valid for any endpoint; a register with a "txep" or 38 * "rxep" parameter is valid only for TX or RX endpoints, respectively. The 39 * "*ep" value is assumed to be less than the maximum valid endpoint ID 40 * for the current hardware, and that will not exceed IPA_ENDPOINT_MAX. 41 * 42 * The offset of registers related to filter and route tables is computed 43 * by a macro that is supplied a parameter "er". The "er" represents an 44 * endpoint ID for filters, or a route ID for routes. For filters, the 45 * endpoint ID must be less than IPA_ENDPOINT_MAX, but is further restricted 46 * because not all endpoints support filtering. For routes, the route ID 47 * must be less than IPA_ROUTE_MAX. 48 * 49 * The offset of registers related to resource types is computed by a macro 50 * that is supplied a parameter "rt". The "rt" represents a resource type, 51 * which is is a member of the ipa_resource_type_src enumerated type for 52 * source endpoint resources or the ipa_resource_type_dst enumerated type 53 * for destination endpoint resources. 54 * 55 * Some registers encode multiple fields within them. For these, each field 56 * has a symbol below defining a field mask that encodes both the position 57 * and width of the field within its register. 58 * 59 * In some cases, different versions of IPA hardware use different offset or 60 * field mask values. In such cases an inline_function(ipa) is used rather 61 * than a MACRO to define the offset or field mask to use. 62 * 63 * Finally, some registers hold bitmasks representing endpoints. In such 64 * cases the @available field in the @ipa structure defines the "full" set 65 * of valid bits for the register. 66 */ 67 68 #define IPA_REG_ENABLED_PIPES_OFFSET 0x00000038 69 70 #define IPA_REG_COMP_CFG_OFFSET 0x0000003c 71 #define ENABLE_FMASK GENMASK(0, 0) 72 #define GSI_SNOC_BYPASS_DIS_FMASK GENMASK(1, 1) 73 #define GEN_QMB_0_SNOC_BYPASS_DIS_FMASK GENMASK(2, 2) 74 #define GEN_QMB_1_SNOC_BYPASS_DIS_FMASK GENMASK(3, 3) 75 #define IPA_DCMP_FAST_CLK_EN_FMASK GENMASK(4, 4) 76 #define IPA_QMB_SELECT_CONS_EN_FMASK GENMASK(5, 5) 77 #define IPA_QMB_SELECT_PROD_EN_FMASK GENMASK(6, 6) 78 #define GSI_MULTI_INORDER_RD_DIS_FMASK GENMASK(7, 7) 79 #define GSI_MULTI_INORDER_WR_DIS_FMASK GENMASK(8, 8) 80 #define GEN_QMB_0_MULTI_INORDER_RD_DIS_FMASK GENMASK(9, 9) 81 #define GEN_QMB_1_MULTI_INORDER_RD_DIS_FMASK GENMASK(10, 10) 82 #define GEN_QMB_0_MULTI_INORDER_WR_DIS_FMASK GENMASK(11, 11) 83 #define GEN_QMB_1_MULTI_INORDER_WR_DIS_FMASK GENMASK(12, 12) 84 #define GEN_QMB_0_SNOC_CNOC_LOOP_PROT_DIS_FMASK GENMASK(13, 13) 85 #define GSI_SNOC_CNOC_LOOP_PROT_DISABLE_FMASK GENMASK(14, 14) 86 #define GSI_MULTI_AXI_MASTERS_DIS_FMASK GENMASK(15, 15) 87 #define IPA_QMB_SELECT_GLOBAL_EN_FMASK GENMASK(16, 16) 88 #define IPA_ATOMIC_FETCHER_ARB_LOCK_DIS_FMASK GENMASK(20, 17) 89 90 #define IPA_REG_CLKON_CFG_OFFSET 0x00000044 91 #define RX_FMASK GENMASK(0, 0) 92 #define PROC_FMASK GENMASK(1, 1) 93 #define TX_WRAPPER_FMASK GENMASK(2, 2) 94 #define MISC_FMASK GENMASK(3, 3) 95 #define RAM_ARB_FMASK GENMASK(4, 4) 96 #define FTCH_HPS_FMASK GENMASK(5, 5) 97 #define FTCH_DPS_FMASK GENMASK(6, 6) 98 #define HPS_FMASK GENMASK(7, 7) 99 #define DPS_FMASK GENMASK(8, 8) 100 #define RX_HPS_CMDQS_FMASK GENMASK(9, 9) 101 #define HPS_DPS_CMDQS_FMASK GENMASK(10, 10) 102 #define DPS_TX_CMDQS_FMASK GENMASK(11, 11) 103 #define RSRC_MNGR_FMASK GENMASK(12, 12) 104 #define CTX_HANDLER_FMASK GENMASK(13, 13) 105 #define ACK_MNGR_FMASK GENMASK(14, 14) 106 #define D_DCPH_FMASK GENMASK(15, 15) 107 #define H_DCPH_FMASK GENMASK(16, 16) 108 #define DCMP_FMASK GENMASK(17, 17) 109 #define NTF_TX_CMDQS_FMASK GENMASK(18, 18) 110 #define TX_0_FMASK GENMASK(19, 19) 111 #define TX_1_FMASK GENMASK(20, 20) 112 #define FNR_FMASK GENMASK(21, 21) 113 #define QSB2AXI_CMDQ_L_FMASK GENMASK(22, 22) 114 #define AGGR_WRAPPER_FMASK GENMASK(23, 23) 115 #define RAM_SLAVEWAY_FMASK GENMASK(24, 24) 116 #define QMB_FMASK GENMASK(25, 25) 117 #define WEIGHT_ARB_FMASK GENMASK(26, 26) 118 #define GSI_IF_FMASK GENMASK(27, 27) 119 #define GLOBAL_FMASK GENMASK(28, 28) 120 #define GLOBAL_2X_CLK_FMASK GENMASK(29, 29) 121 122 #define IPA_REG_ROUTE_OFFSET 0x00000048 123 #define ROUTE_DIS_FMASK GENMASK(0, 0) 124 #define ROUTE_DEF_PIPE_FMASK GENMASK(5, 1) 125 #define ROUTE_DEF_HDR_TABLE_FMASK GENMASK(6, 6) 126 #define ROUTE_DEF_HDR_OFST_FMASK GENMASK(16, 7) 127 #define ROUTE_FRAG_DEF_PIPE_FMASK GENMASK(21, 17) 128 #define ROUTE_DEF_RETAIN_HDR_FMASK GENMASK(24, 24) 129 130 #define IPA_REG_SHARED_MEM_SIZE_OFFSET 0x00000054 131 #define SHARED_MEM_SIZE_FMASK GENMASK(15, 0) 132 #define SHARED_MEM_BADDR_FMASK GENMASK(31, 16) 133 134 #define IPA_REG_QSB_MAX_WRITES_OFFSET 0x00000074 135 #define GEN_QMB_0_MAX_WRITES_FMASK GENMASK(3, 0) 136 #define GEN_QMB_1_MAX_WRITES_FMASK GENMASK(7, 4) 137 138 #define IPA_REG_QSB_MAX_READS_OFFSET 0x00000078 139 #define GEN_QMB_0_MAX_READS_FMASK GENMASK(3, 0) 140 #define GEN_QMB_1_MAX_READS_FMASK GENMASK(7, 4) 141 /* The next two fields are present for IPA v4.0 and above */ 142 #define GEN_QMB_0_MAX_READS_BEATS_FMASK GENMASK(23, 16) 143 #define GEN_QMB_1_MAX_READS_BEATS_FMASK GENMASK(31, 24) 144 145 static inline u32 ipa_reg_state_aggr_active_offset(enum ipa_version version) 146 { 147 if (version == IPA_VERSION_3_5_1) 148 return 0x0000010c;
