4.2.12 Integrated Memory Controller Error Injection Registers
Complete address match (Addr[45:3]) and mask is supported for all Home Agent
writes. Error injection does not use the response logic triggers and uses the match
mask logic output to determine which writes need to get error injection. Users can
program up to two x4 device masks (8-bits per chunk - 64 bits per cacheline).
4.2.12.1 PXPENHCAP—PCI Express* Capability Register
This field points to the next Capability in extended configuration space.
4.2.12.2 RIRWAYNESSLIMIT_[0:4]—RIR Range Wayness and
Limit Register
There are total of 5 RIR ranges (represents how many rank interleave ranges supported
to cover customer DIMM configuration.).

RIR_LIMIT
RIR[5:0].LIMIT[38:29] == highest address of the range in channel address space,
192 GB in independent channel, 512 MB granularity. M= How many rank
interleave ranges supported to cover customer DIMM configuration. In the
processor M=6.
