Subject: broken maxcpus in 2.4.24
Date: Mon, 02 Feb 2004 15:37:14 -0800 [thread overview]
Message-ID: <1075765034.17943.79.camel@reactor.us.proofpoint.com> (raw)
I compiled a vanilla 2.4.24 for a 2 processor Xeon.
I set CONFIG_NR_CPUS to 4 (2 CPUs x 2 hyperthreads each).
When I boot the kernel, /proc/cpuinfo only shows 2 cpus (0-1) and
performance is bad.
I reconfigure CONFIG_NR_CPUS back to 32. Now it shows 4 cpus (0-3) and
performance is normal.
Is this a bug or am misunderstanding how to set this configuration
variable?
