the DM tag machine.
0: Disable.
1: Enable. (Default)
Reserved. (Default = 0)
Number of Outstanding Write-Serialized Requests. The system must be able to
accept WSREQ+1 cacheline + 2-4 QWORD writes without backing up the bus controller
to prevent a lockup condition in the event of an inbound snoop hit.
000: Unlimited. (Default)
001-111: Binary value.
Reserved. (Default = 0)
Write-Combine Timeout. Flushes write-combinable entry from write buffer if it has not
been written for the specified number of clocks.
000: Disable timeout. (Default)
001-111: 2**(4 + WCTO) clocks (32, 64, ..., 2048).
Reserved. (Default = 0)
Write-Burst Timeout. Flushes write-burstable entry from write buffer if it has not been
written for the specified number of clocks.
000: Disable timeout. (Default)
001-111: 2**(4 + WBTO) clocks (32, 64, ..., 2048).
