From eb5601c57b7797c7d36498c0a228da52f7cf33d6 Mon Sep 17 00:00:00 2001 From: Eitan Adler <eadler@FreeBSD.org> Date: Sun, 19 May 2013 01:02:30 +0000 Subject: [PATCH] Improve the smp-support question wording for the modern era. Indicate that certain ARM cpus may have issues. This is based on information and wording from gavin. --- en_US.ISO8859-1/books/faq/book.xml | 17 +++++++---------- 1 file changed, 7 insertions(+), 10 deletions(-) diff --git a/en_US.ISO8859-1/books/faq/book.xml b/en_US.ISO8859-1/books/faq/book.xml index ea7f0a7ce8..8a5674349f 100644 --- a/en_US.ISO8859-1/books/faq/book.xml +++ b/en_US.ISO8859-1/books/faq/book.xml @@ -1680,16 +1680,13 @@ </question> <answer> - <para>Symmetric multi-processor (SMP) systems are generally - supported by &os;, although in some cases, BIOS or - motherboard bugs may generate some problems.</para> - - <para>&os; will take advantage of HyperThreading (HTT) - support on &intel; CPUs that support this feature.
