189 G3 and G4 processors have an on-chip temperature sensor called the
190 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
191 temperature within 2-4 degrees Celsius. This option shows the current
192 on-die temperature in /proc/cpuinfo if the cpu supports it.
193
194 Unfortunately, on some chip revisions, this sensor is very inaccurate

202 The TAU supports an interrupt driven mode which causes an interrupt
203 whenever the temperature goes out of range. This is the fastest way
204 to get notified the temp has exceeded a range. With this option off,
205 a timer is used to re-check the temperature periodically.
206
207 However, on some cpus it appears that the TAU interrupt hardware
208 is buggy and can cause a situation which would lead unexplained hard
209 lockups.

218 The TAU hardware can compare the temperature to an upper and lower

220 bound in /proc/cpuinfo. If the range is large, the temperature is
221 either changing a lot, or the TAU hardware is broken (likely on some
222 G4's). If the range is small (around 4 degrees), the temperature is
223 relatively stable. If you say Y here, a single temperature value,
224 halfway between the upper and lower bounds, will be reported in

235 floating-point instructions in the PowerPC instruction set. If you

249 kexec is a system call that implements the ability to shutdown your

Matt LaPlante1f1332f2006-06-29 01:32:47 -0400251 but it is independent of the system firmware. And like a reboot
Eric W. Biederman70765aa2005-06-25 14:58:07 -0700252 you can start any kernel with it, not just Linux.
253
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400254 The name comes from the similarity to the exec system call.
Eric W. Biederman70765aa2005-06-25 14:58:07 -0700255
256 It is an ongoing process to be certain the hardware in a machine
257 is properly shutdown, so do not be surprised if this code does not
258 initially work for you. It may help to enable device hotplugging
259 support. As of this writing the exact hardware interface is
260 strongly in flux, so no good recommendation can be made.

263 run DOL files, including kernel and homebrew DOLs.
