The offset of each register within that space is specified * by symbols defined below. The address space is mapped to virtual memory * space in ipa_mem_init(). All IPA registers are 32 bits wide. * * Certain 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. For such registers, the offset is * computed by a function-like macro that takes a parameter used in the * computation. * * Some register offsets depend on execution environment. For these an "ee" * parameter is supplied to the offset macro. The "ee" value is a member of * the gsi_ee enumerated type. * * The offset of a register dependent on endpoint id is computed by a macro * that is supplied a parameter "ep". The "ep" value is assumed to be less * than the maximum endpoint value for the current hardware, and that will * not exceed IPA_ENDPOINT_MAX. * * The offset of registers related to filter and route tables is computed * by a macro that is supplied a parameter "er". The "er" represents an * endpoint ID for filters, or a route ID for routes. For filters, the * endpoint ID must be less than IPA_ENDPOINT_MAX, but is further restricted * because not all endpoints support filtering. For routes, the route ID * must be less than IPA_ROUTE_MAX. * * The offset of registers related to resource types is computed by a macro * that is supplied a parameter "rt". The "rt" represents a resource type, * which is is a member of the ipa_resource_type_src enumerated type for * source endpoint resources or the ipa_resource_type_dst enumerated type * for destination endpoint resources. * * Some registers encode multiple fields within them. For these, each field * has a symbol below defining a field mask that encodes both the position * and width of the field within its register. * * In some cases, different versions of IPA hardware use different offset or * field mask values. In such cases an inline_function(ipa) is used rather * than a MACRO to define the offset or field mask to use. * * Finally, some registers hold bitmasks representing endpoints. In such * cases the @available field in the @ipa structure defines the "full" set * of valid bits for the register. */ #define IPA_REG_ENABLED_PIPES_OFFSET 0x00000038 #define IPA_REG_COMP_CFG_OFFSET
