The offset of each register within that space is specified by 18 * symbols defined below. The GSI address space is mapped to virtual memory 19 * space in gsi_init(). All GSI registers are 32 bits wide. 20 * 21 * Each register type is duplicated for a number of instances of something. 22 * For example, each GSI channel has its own set of registers defining its 23 * configuration. The offset to a channel's set of registers is computed 24 * based on a "base" offset plus an additional "stride" amount computed 25 * from the channel's ID. For such registers, the offset is computed by a 26 * function-like macro that takes a parameter used in the computation. 27 * 28 * The offset of a register dependent on execution environment is computed 29 * by a macro that is supplied a parameter "ee". The "ee" value is a member 30 * of the gsi_ee_id enumerated type. 31 * 32 * The offset of a channel register is computed by a macro that is supplied a 33 * parameter "ch". The "ch" value is a channel id whose maximum value is 30 34 * (though the actual limit is hardware-dependent). 35 * 36 * The offset of an event register is computed by a macro that is supplied a 37 * parameter "ev". The "ev" value is an event id whose maximum value is 15 38 * (though the actual limit is hardware-dependent). 39 */ 40 41 /* GSI EE registers as a group are shifted downward by a fixed constant amount 42 * for IPA versions 4.5 and beyond. This applies to all GSI registers we use 43 * *except* the ones that disable inter-EE interrupts for channels and event 44 * channels. 45 * 46 * The "raw" (not adjusted) GSI register range is mapped, and a pointer to 47 * the mapped range is held in gsi->virt_raw. The inter-EE interrupt 48 * registers are accessed using that pointer. 49 * 50 * Most registers are accessed using gsi->virt, which is a copy of the "raw" 51 * pointer, adjusted downward by the fixed amount. 52 */ 53 #define GSI_EE_REG_ADJUST 0x0000d000 /* IPA v4.5+ */ 54 55 /* The inter-EE IRQ registers are relative to gsi->virt_raw (IPA v3.5+) */ 56 57 #define GSI_INTER_EE_SRC_CH_IRQ_MSK_OFFSET \ 58 GSI_INTER_EE_N_SRC_CH_IRQ_MSK_OFFSET(GSI_EE_AP) 59 #define GSI_INTER_EE_N_SRC_CH_IRQ_MSK_OFFSET(ee) \ 60 (0x0000c020 + 0x1000 * (ee)) 61 62 #define GSI_INTER_EE_SRC_EV_CH_IRQ_MSK_OFFSET \ 63 GSI_INTER_EE_N_SRC_EV_CH_IRQ_MSK_OFFSET(GSI_EE_AP) 64 #define GSI_INTER_EE_N_SRC_EV_CH_IRQ_MSK_OFFSET(ee) \ 65 (0x0000c024 + 0x1000 * (ee)) 66 67 /* All other register offsets are relative to gsi->virt */ 68 69 /** enum gsi_channel_type - CHTYPE_PROTOCOL field values in CH_C_CNTXT_0 */ 70 enum gsi_channel_type { 71 GSI_CHANNEL_TYPE_MHI = 0x0, 72 GSI_CHANNEL_TYPE_XHCI = 0x1, 73 GSI_CHANNEL_TYPE_GPI = 0x2, 74 GSI_CHANNEL_TYPE_XDCI = 0x3, 75 GSI_CHANNEL_TYPE_WDI2 = 0x4, 76 GSI_CHANNEL_TYPE_GCI = 0x5, 77 GSI_CHANNEL_TYPE_WDI3 = 0x6, 78 GSI_CHANNEL_TYPE_MHIP = 0x7, 79 GSI_CHANNEL_TYPE_AQC = 0x8, 80 GSI_CHANNEL_TYPE_11AD = 0x9, 81 };
