16 * DOC: IPA Registers
17 *
18 * IPA registers are located within the "ipa-reg" address space defined by
19 * Device Tree. Each register has a specified offset within that space,
20 * which is mapped into virtual memory space in ipa_mem_init(). Each
21 * has a unique identifer, taken from the ipa_reg_id enumerated type.
22 * All IPA registers are 32 bits wide.
23 *
24 * Certain "parameterized" register types are duplicated for a number of
25 * instances of something. For example, each IPA endpoint has an set of
26 * registers defining its configuration. The offset to an endpoint's set
27 * of registers is computed based on an "base" offset, plus an endpoint's
28 * ID multiplied and a "stride" value for the register. Similarly, some
29 * registers have an offset that depends on execution environment. In
30 * this case, the stride is multiplied by a member of the gsi_ee_id
31 * enumerated type.
32 *
33 * Each version of IPA implements an array of ipa_reg structures indexed
34 * by register ID. Each entry in the array specifies the base offset and
35 * (for parameterized registers) a non-zero stride value. Not all versions
36 * of IPA define all registers. The offset for a register is returned by
37 * reg_offset() when the register's ipa_reg structure is supplied;
38 * zero is returned for an undefined register (this should never happen).
39 *
40 * Some registers encode multiple fields within them. Each field in
41 * such a register has a unique identifier (from an enumerated type).
42 * The position and width of the fields in a register are defined by
43 * an array of field masks, indexed by field ID. Two functions are
44 * used to access register fields; both take an ipa_reg structure as
45 * argument. To encode a value to be represented in a register field,
46 * the value and field ID are passed to reg_encode(). To extract
47 * a value encoded in a register field, the field ID is passed to
48 * reg_decode(). In addition, for single-bit fields, reg_bit()
49 * can be used to either encode the bit value, or to generate a mask
50 * used to extract the bit value.
