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". The "ep" value is assumed to be less 37 * than the maximum endpoint value for the current hardware, and that will 38 * not exceed IPA_ENDPOINT_MAX. 39 * 40 * The offset of registers related to filter and route tables is computed 41 * by a macro that is supplied a parameter "er". The "er" represents an 42 * endpoint ID for filters, or a route ID for routes. For filters, the 43 * endpoint ID must be less than IPA_ENDPOINT_MAX, but is further restricted 44 * because not all endpoints support filtering. For routes, the route ID 45 * must be less than IPA_ROUTE_MAX. 46 * 47 * The offset of registers related to resource types is computed by a macro 48 * that is supplied a parameter "rt". The "rt" represents a resource type, 49 * which is is a member of the ipa_resource_type_src enumerated type for 50 * source endpoint resources or the ipa_resource_type_dst enumerated type 51 * for destination endpoint resources. 52 * 53 * Some registers encode multiple fields within them. For these, each field 54 * has a symbol below defining a field mask that encodes both the position 55 * and width of the field within its register. 56 * 57 * In some cases, different versions of IPA hardware use different offset or 58 * field mask values. In such cases an inline_function(ipa) is used rather 59 * than a MACRO to define the offset or field mask to use. 60 * 61 * Finally, some registers hold bitmasks representing endpoints. In such 62 * cases the @available field in the @ipa structure defines the "full" set 63 * of valid bits for the register. 64 */ 65 66 #define IPA_REG_ENABLED_PIPES_OFFSET 0x00000038 67 68 #define
