14 * DOC: GSI Registers
15 *
16 * GSI registers are located within the "gsi" address space defined by Device
17 * Tree. 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 */

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.
