Register Description 2.6.7 Device: 0 Function: 1 Offset: 80h, 84h, 88h, 8Ch, 90h, 94h, 98h, 9Ch Access as a Dword 19:6 RW 2:1 RW 0 RW LIMIT DRAM rule top limit address. Must be strictly greater than previous rule, even if - this rule is disabled, unless this rule and all following rules are disabled. Lower limit is the previous rule (or 0 if it is first rule). This field is compared against MA[39:26] in the memory address map. MODE DRAM rule interleave mode. If a DRAM_RULE hits a 3 bit number is used to index into the corresponding interleave_list to determine which package the DRAM belongs to. This mode selects how that number is computed. - 00 = Address bits {8,7,6}. 01 = Address bits {8,7,6} XORed with {18,17,16}. 10 = Address bit {6}, MOD3(Address[39..6]). (Note 6 is the high order bit) 11 = Reserved. ENABLE Enable for DRAM rule. If Enabled Range between this rule and previous rule is 0 Directed to HOME channel (unless overridden by other dedicated address range registers). If disabled, all accesses in this range are directed in MMIO to the IOH. SAD_INTERLEAVE_LIST_0, SAD_INTERLEAVE_LIST_1 SAD_INTERLEAVE_LIST_2, SAD_INTERLEAVE_LIST_3 SAD_INTERLEAVE_LIST_4, SAD_INTERLEAVE_LIST_5 SAD_INTERLEAVE_LIST_6, SAD_INTERLEAVE_LIST_7 This register provides SAD DRAM package assignments. When the corresponding DRAM_RULE hits, a 3-bit number (determined by mode) is used to index into the interleave_list to determine which package is the HOME for this address. 00: IOH 01: Socket 0 10: Socket 1 11: Reserved Device: 0 Function: 1 Offset: C0h, C4h, C8h, CCh, D0h, D4h, D8h, DCh Access as a Dword Bit 29:28 25:24 21:20 17:16 13:12 9:8 5:4 1:0 Type RW RW RW RW RW RW RW RW Reset Value Description - PACKAGE7.
