| * | x86, UV: Fix RTC latency bug by reading replicated cachelines | Dimitri Sivanich | 2010-01-27 | 1 | -7/+11 |
| | | | | | | | | | | | | For SGI UV node controllers (HUB) rev 2.0 or greater, use replicated cachelines to read the RTC timer. This optimization allows faster simulataneous reads from a given socket.
