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).

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.
