76 * Reserved Page provided by SAL. 71 * the reserved page
72 *
73 * SAL reserves one page of memory per partition for XPC. Though a full page
74 * in length (16384 bytes), its starting address is not page aligned, but it
75 * is cacheline aligned. The reserved page consists of the following:
76 *
77 * reserved page header
78 *
79 * The first cacheline of the reserved page contains the header
80 * (struct xpc_rsvd_page). Before SAL initialization has completed,
81 * SAL has set up the following fields of the reserved page header:
82 * SAL_signature, SAL_version, partid, and nasids_size. The other
83 * fields are set up by XPC. (xpc_rsvd_page points to the local
84 * partition's reserved page.)
77 * 85 *
78 * SAL provides one page per partition of reserved memory. When SAL 86 * part_nasids mask
79 * initialization is complete, SAL_signature, SAL_version, partid, 87 * mach_nasids mask
80 * part_nasids, and mach_nasids are set. 88 *
89 * SAL also sets up two bitmaps (or masks), one that reflects the actual
90 * nasids in this partition (part_nasids), and the other that reflects
91 * the actual nasids in the entire machine (mach_nasids). We're only
92 * interested in the even numbered nasids (which contain the processors
93 * and/or memory), so we only need half as many bits to represent the
94 * nasids. The part_nasids mask is located starting at the first cacheline
95 * following the reserved page header. The mach_nasids mask follows right
96 * after the part_nasids mask. The size in bytes of each mask is reflected
97 * by the reserved page header field 'nasids_size'. (Local partition's
98 * mask pointers are xpc_part_nasids and xpc_mach_nasids.)
99 *
100 * vars
101 * vars part
102 *
103 * Immediately following the mach_nasids mask are the XPC variables
104 * required by other partitions. First are those that are generic to all
105 * partitions (vars), followed on the next available cacheline by those
106 * which are partition specific (vars part). These are setup by XPC.
107 * (Local partition's vars pointers are xpc_vars and xpc_vars_part.)
81 * 108 *
82 * Note: Until vars_pa is set, the partition XPC code has not been initialized. 109 * Note: Until vars_pa is set, the partition XPC code has not been initialized.
