linux-toradex.git/drivers/char/uv_mmtimer.c, branch v2.6.34 Linux kernel for Apalis and Colibri modules x86, UV: Fix RTC latency bug by reading replicated cachelines 2010-01-27T10:33:53+00:00 Dimitri Sivanich sivanich@sgi.com 2010-01-22T15:41:40+00:00 aca3bb5910119d4cf6c28568a642582efb4cc14a 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.
