Chapter 1 Installing Software From the Solaris CD 11
The code sequence that exploits the problem is very unusual, and is not likely to be
generated by a compiler. Assembler code had to be specifically written to
demonstrate the problem. It is highly unlikely that a legitimate handwritten
assembler routine would use this code sequence.
Users willing to assume the risk that a user might accidentally or deliberately run a
program that was designed to cause a processor to stall may choose to run the
Solaris 64-bit kernel on these systems.
You can determine the speed of your processor(s) by typing:
You can change the default kernel from 32-bit on a system by modifying the
boot
policy file. Edit the
/platform/
platform-name
/boot.conf
file so that it contains an
uncommented line with the variable named
ALLOW_64BIT_KERNEL_ON_UltraSPARC_1_CPU
set to the value
true
as shown
in the example that follows:
ALLOW_64BIT_KERNEL_ON_UltraSPARC_1_CPU=true
See
boot
(1M) for more information about changing the default kernel.
You may also purchase an upgrade to your system, contact your Sun representative
for details.
