| H A D | dawr-power9.rst | diff 26b78c81e84c5133b299fb11bf17ec1a3d2ad217 Tue May 03 12:01:52 CDT 2022 Reza Arbab <arbab@linux.ibm.com> powerpc: Enable the DAWR on POWER9 DD2.3 and above
The hardware bug in POWER9 preventing use of the DAWR was fixed in
DD2.3. Set the CPU_FTR_DAWR feature bit on these newer systems to start
using it again, and update the documentation accordingly.
The CPU features for DD2.3 are currently determined by "DD2.2 or later"
logic. In adding DD2.3 as a discrete case for the first time here, I'm
carrying the quirks of DD2.2 forward to keep all behavior outside of
this DAWR change the same. This leaves the assessment and potential
removal of those quirks on DD2.3 for later.
