Message-ID: <20131105143816.GK9944@hansolo.jdub.homelinux.org> Date: Tue, 5 Nov 2013 09:38:16 -0500 From: Josh Boyer <jwboyer@...hat.com> To: Thomas Gleixner <tglx@...utronix.de>, Ingo Molnar <mingo@...hat.com>, "H. Peter Anvin" <hpa@...or.com> Cc: prarit@...hat.com, x86@...nel.org, linux-kernel@...r.kernel.org, Russ Anderson <rja@....com> Subject: [PATCH 2/2] x86: Increase MAXSMP CPU count to 8192 The MAXSMP option is intended to enable silly large numbers of CPUs for testing purposes. The current value of 4096 isn't very silly any longer as there are actual machines that approach 6096 CPUs when taking HT into account. Increase the value to 8192 to account for this and short term future increases.
