Description
Data Cache Data. QWORD data to read from or write to the cache line buffer. The buffer
is filled from the cache data array on a read to DC_TAG_MSR (MSR 00001892h) or
DC_TAG_I_MSR (MSR 00001893h), and the buffer is written to the cache data array on
a write to DC_TAG_MSR or DC_TAG_I_MSR MSRs. The DC_DSEL field in the
DC_INDEX_MSR (MSR 00001890h[17:16]) selects which QWORD in the buffer is
accessed by DC_DATA, and each access to DC_DATA increments DC_DSEL.
