Processor
"Processor Type"
 * default 6xx


 * Option: 6xx
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "6xx/7xx/74xx/52xx/82xx/83xx"
 * select PPC_FPU
 * There are four types of PowerPC chips supported. The more common types (601, 603, 604, 740, 750, 7400), the Motorola embedded versions (821, 823, 850, 855, 860, 52xx, 82xx, 83xx), the IBM embedded versions (403 and 405) and the high end 64 bit Power processors (POWER 3, POWER4, and IBM 970 also known as G5) Unless you are building a kernel for one of the embedded processor systems, 64 bit IBM RS/6000 or an Apple G5, choose 6xx. Note that the kernel runs in 32-bit mode even on 64-bit chips. Also note that because the 52xx, 82xx, & 83xx family has a 603e core, specific support for that chipset is asked later on.


 * Option: 40x
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "40x"


 * Option: 44x
 * Kernel Versions: 2.6.15.6 ...

 * (on/off) "e500"


 * Option: PPC_FPU
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)


 * Option: BOOKE
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * depends on E200 || E500
 * default y


 * Option: FSL_BOOKE
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * depends on E200 || E500
 * default y


 * Option: PTE_64BIT
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * depends on 44x || E500
 * default y if 44x
 * default y if E500 && PHYS_64BIT


 * Option: PHYS_64BIT
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) 'Large physical address support' if E500
 * depends on 44x || E500
 * default y if 44x
 * This option enables kernel support for larger than 32-bit physical addresses. This features is not be available on all e500 cores.
 * If in doubt, say N here.


 * Option: ALTIVEC
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "AltiVec Support"
 * depends on 6xx || POWER4
 * depends on !8260 && !83xx
 * This option enables kernel support for the Altivec extensions to the PowerPC processor. The kernel currently supports saving and restoring altivec registers, and turning on the 'altivec enable' bit so user processes can execute altivec instructions.
 * This option is only usefully if you have a processor that supports altivec (G4, otherwise known as 74xx series), but does not have any affect on a non-altivec cpu (it does, however add code to the kernel).
 * If in doubt, say Y here.


 * Option: SPE
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "SPE Support"
 * depends on E200 || E500
 * This option enables kernel support for the Signal Processing Extensions (SPE) to the PowerPC processor. The kernel currently supports saving and restoring SPE registers, and turning on the 'spe enable' bit so user processes can execute SPE instructions.
 * This option is only useful if you have a processor that supports SPE (e500, otherwise known as 85xx series), but does not have any effect on a non-spe cpu (it does, however add code to the kernel).
 * If in doubt, say Y here.


 * Option: TAU
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "Thermal Management Support"
 * depends on 6xx && !8260 && !83xx
 * G3 and G4 processors have an on-chip temperature sensor called the 'Thermal Assist Unit (TAU)', which, in theory, can measure the on-die temperature within 2-4 degrees Celsius. This option shows the current on-die temperature in /proc/cpuinfo if the cpu supports it.
 * Unfortunately, on some chip revisions, this sensor is very inaccurate and in some cases, does not work at all, so don't assume the cpu temp is actually what /proc/cpuinfo says it is.


 * Option: TAU_INT
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "Interrupt driven TAU driver (DANGEROUS)"
 * depends on TAU
 * The TAU supports an interrupt driven mode which causes an interrupt whenever the temperature goes out of range. This is the fastest way to get notified the temp has exceeded a range. With this option off, a timer is used to re-check the temperature periodically.
 * However, on some cpus it appears that the TAU interrupt hardware is buggy and can cause a situation which would lead unexplained hard lockups.
 * Unless you are extending the TAU driver, or enjoy kernel/hardware debugging, leave this option off.


 * Option: TAU_AVERAGE
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "Average high and low temp"
 * depends on TAU
 * The TAU hardware can compare the temperature to an upper and lower bound. The default behavior is to show both the upper and lower bound in /proc/cpuinfo. If the range is large, the temperature is either changing a lot, or the TAU hardware is broken (likely on some G4's). If the range is small (around 4 degrees), the temperature is relatively stable.  If you say Y here, a single temperature value, halfway between the upper and lower bounds, will be reported in /proc/cpuinfo.
 * If in doubt, say N here.


 * Option: MATH_EMULATION
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "Math emulation"
 * depends on 4xx || 8xx || E200 || E500
 * Some PowerPC chips designed for embedded applications do not have a floating-point unit and therefore do not implement the floating-point instructions in the PowerPC instruction set. If you say Y here, the kernel will include code to emulate a floating-point unit, which will allow programs that use floating-point instructions to run.
 * If you have an Apple machine or an IBM RS/6000 or pSeries machine, or any machine with a 6xx, 7xx or 7xxx series processor, say N here. Saying Y here will not hurt performance (on any machine) but will increase the size of the kernel.


 * Option: KEXEC
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "kexec system call (EXPERIMENTAL)"
 * depends on EXPERIMENTAL
 * kexec is a system call that implements the ability to shutdown your current kernel, and to start another kernel. It is like a reboot but it is indepedent of the system firmware.   And like a reboot you can start any kernel with it, not just Linux.
 * The name comes from the similiarity to the exec system call.
 * It is an ongoing process to be certain the hardware in a machine is properly shutdown, so do not be surprised if this code does not initially work for you. It may help to enable device hotplugging support.  As of this writing the exact hardware interface is strongly in flux, so no good recommendation can be made.
 * In the GameCube implementation, kexec allows you to load and run DOL files, including kernel and homebrew DOLs.


 * Option: User:ZyMOS/Howto configure the linux kernel/drivers/cpufreq


 * Option: CPU_FREQ_PMAC
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "Support for Apple PowerBooks"
 * depends on CPU_FREQ && ADB_PMU
 * select CPU_FREQ_TABLE
 * This adds support for frequency switching on Apple PowerBooks, this currently includes some models of iBook & Titanium PowerBook.


 * Option: PPC601_SYNC_FIX
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "Workarounds for PPC601 bugs"
 * depends on 6xx && (PPC_PREP || PPC_PMAC)
 * Some versions of the PPC601 (the first PowerPC chip) have bugs which mean that extra synchronization instructions are required near certain instructions, typically those that make major changes to the CPU state. These extra instructions reduce performance slightly. If you say N here, these extra instructions will not be included, resulting in a kernel which will run faster but may not run at all on some systems with the PPC601 chip.
 * If in doubt, say Y here.


 * Option: HOTPLUG_CPU
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) "Support for enabling/disabling CPUs"
 * depends on SMP && HOTPLUG && EXPERIMENTAL && PPC_PMAC
 * Say Y here to be able to disable and re-enable individual CPUs at runtime on SMP machines.
 * Say N if you are unsure.

At a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The ports were connected with 8 pin DIN connectors on the card bracket, for which 8 pin to DB25 adapters were supplied. The card also had jumpers internally to toggle various pinning configurations.
 * This driver can be built as a module; but then "generic_serial" will also be built as a module. This has to be loaded before "ser_a2232". If you want to do this, answer M here.
