160 G3 and G4 processors have an on-chip temperature sensor called the
161 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die
162 temperature within 2-4 degrees Celsius. This option shows the current
163 on-die temperature in /proc/cpuinfo if the cpu supports it.
164
165 Unfortunately, on some chip revisions, this sensor is very inaccurate
166 and in some cases, does not work at all, so don't assume the cpu
167 temp is actually what /proc/cpuinfo says it is.

169config TAU_INT

172 ---help---
173 The TAU supports an interrupt driven mode which causes an interrupt
174 whenever the temperature goes out of range. This is the fastest way
175 to get notified the temp has exceeded a range. With this option off,
176 a timer is used to re-check the temperature periodically.
177
178 However, on some cpus it appears that the TAU interrupt hardware
179 is buggy and can cause a situation which would lead unexplained hard
180 lockups.
181
182 Unless you are extending the TAU driver, or enjoy kernel/hardware
183 debugging, leave this option off.
184
185config TAU_AVERAGE
186 bool "Average high and low temp"

188 ---help---
189 The TAU hardware can compare the temperature to an upper and lower
190 bound. The default behavior is to show both the upper and lower
191 bound in /proc/cpuinfo. If the range is large, the temperature is
192 either changing a lot, or the TAU hardware is broken (likely on some
193 G4's). If the range is small (around 4 degrees), the temperature is
194 relatively stable. If you say Y here, a single temperature value,
195 halfway between the upper and lower bounds, will be reported in
196 /proc/cpuinfo.

204 Some PowerPC chips designed for embedded applications do not have
205 a floating-point unit and therefore do not implement the
206 floating-point instructions in the PowerPC instruction set. If you
207 say Y here, the kernel will include code to emulate a floating-point
208 unit, which will allow programs that use floating-point
209 instructions to run.

212 or any machine with a 6xx, 7xx or 7xxx series processor, say N

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

Matt LaPlante1f1332f2006-06-29 01:32:47 -0400222 but it is independent of the system firmware. And like a reboot
Eric W. Biederman70765aa2005-06-25 14:58:07 -0700223 you can start any kernel with it, not just Linux.
224
Matt LaPlante1f1332f2006-06-29 01:32:47 -0400225 The name comes from the similarity to the exec system call.
Eric W. Biederman70765aa2005-06-25 14:58:07 -0700226
227 It is an ongoing process to be certain the hardware in a machine
228 is properly shutdown, so do not be surprised if this code does not
229 initially work for you. It may help to enable device hotplugging
230 support. As of this writing the exact hardware interface is
231 strongly in flux, so no good recommendation can be made.

233 In the GameCube implementation, kexec allows you to load and
234 run DOL files, including kernel and homebrew DOLs.

891 This enables support for systems with more than one CPU. If you have
892 a system with only one CPU, say N. If you have a system with more
893 than one CPU, say Y. Note that the kernel does not currently
894 support SMP machines with 603/603e/603ev or PPC750 ("G3") processors
895 since they have inadequate hardware support for multiprocessor
896 operation.

899 machines, but will use only one CPU of a multiprocessor machine. If
