with major 203 and minors 0 to 31 for /dev/cpu/0/cpuid to
/dev/cpu/31/cpuid.
CONFIG_NR_CPUS
This allows you to specify the maximum number of CPUs which this
kernel will support. The maximum supported value is 32 and the
minimum value which makes sense is 2.
This is purely to save memory - each supported CPU adds
approximately eight kilobytes to the kernel image.
CONFIG_PREEMPT
This option reduces the latency of the kernel when reacting to
real-time or interactive events by allowing a low priority process to
......@@ -487,10 +495,6 @@ CONFIG_CHECKING
Enables some internal consistency checks for kernel debugging.
You should normally say N.
CONFIG_SIMNOW
Disable some time consuming optional things for slow CPU simulators.
Say N unless you're running on a slow simulator like Simics or SimNow.
CONFIG_EARLY_PRINTK
Write kernel log output directly into the VGA buffer. This is useful
for kernel debugging when your machine crashes very early before

klogd/syslogd or the X server.You should normally N here, unless
you want to debug such a crash.
CONFIG_X86_MCE_NONFATAL
Enabling this feature starts a timer that triggers every 5 seconds which
will look at the machine check registers to see if anything happened.
Non-fatal problems automatically get corrected (but still logged).
Disable this if you don't want to see these messages.
Seeing the messages this option prints out may be indicative of dying hardware,
or out-of-spec (ie, overclocked) hardware.
This option only does something on hardware with Intel P6 style MCE.
(Pentium Pro and above, AMD Athlon/Duron)
CONFIG_KALLSYMS
Say Y here to let the kernel print out symbolic crash information and
symbolic stack backtraces. This increases the size of the kernel
somewhat, as all symbols have to be loaded into the kernel image.
CONFIG_INIT_DEBUG
Fill __init and __initdata at the end of boot. This is only for debugging.
CONFIG_IA32_EMULATION
Include code to run 32bit programs under an 64bit kernel. You should likely
turn this on, unless you're 100% sure that you don't have any 32bit programs
left.
CONFIG_GART_IOMMU
Support the K8 IOMMU. Needed to run systems with more than 4GB of memory
properly with 32bit devices. You should probably turn this on.
The iommu can be turned off at runtime with the iommu=off parameter.
CONFIG_DUMMY_IOMMU
Don't use IOMMU code. This will cause problems when you have more than 4GB
of memory and any 32bit devices. Don't turn on unless you know what you
are doing.

/* This needs more work before we can enable it. Unfortunately
* because of the fancy asynchronous way URB status/error is written
* back to userspace, we'll need to fiddle with USB devio internals
* and/or reimplement entirely the frontend of it ourselves. -DaveM
*
* The issue is:
*
* When an URB is submitted via usbdevicefs it is put onto an
* asynchronous queue. When the URB completes, it may be reaped
* via another ioctl. During this reaping the status is written
* back to userspace along with the length of the transfer.
*
* We must translate into 64-bit kernel types so we pass in a kernel
* space copy of the usbdevfs_urb structure. This would mean that we
* must do something to deal with the async entry reaping. First we
* have to deal somehow with this transitory memory we've allocated.
* This is problematic since there are many call sites from which the
* async entries can be destroyed (and thus when we'd need to free up
* this kernel memory). One of which is the close() op of usbdevicefs.
* To handle that we'd need to make our own file_operations struct which
* overrides usbdevicefs's release op with our own which runs usbdevicefs's
* real release op then frees up the kernel memory.
*
* But how to keep track of these kernel buffers? We'd need to either
* keep track of them in some table _or_ know about usbdevicefs internals
* (ie. the exact layout of it's file private, which is actually defined
* in linux/usbdevice_fs.h, the layout of the async queues are private to
* devio.c)
*
* There is one possible other solution I considered, also involving knowledge
* of usbdevicefs internals:
*
* After an URB is submitted, we "fix up" the address back to the user
* space one. This would work if the status/length fields written back
* by the async URB completion lines up perfectly in the 32-bit type with
* the 64-bit kernel type. Unfortunately, it does not because the iso
* frame descriptors, at the end of the struct, can be written back.
*
* I think we'll just need to simply duplicate the devio URB engine here.
