-APIC and IO-APIC Support on Uniprocessors
+IO-APIC Support on Uniprocessors
CONFIG_X86_UP_IOAPIC
- APIC (Advanced Programmable Interrupt Controller) is a scheme for
- delivering hardware interrupt requests to the CPU. It is commonly
- used on systems with several CPU's. If you have a single-CPU system
- which uses APIC, you can say Y here to use it. If you say Y here
- even though your machine doesn't have APIC, then the kernel will
- still run with no slowdown at all.
-
- If you have system with several CPU's, you do not need to say Y
- here: APIC will be used automatically.
+ An IO-APIC (I/O Advanced Programmable Interrupt Controller) is an
+ SMP-capable replacement for PC-style interrupt controllers. Most
+ SMP systems and a small number of uniprocessor systems have one.
+ If you have a single-CPU system with an IO-APIC, you can say Y here
+ to use it. If you say Y here even though your machine doesn't have
+ an IO-APIC, then the kernel will still run with no slowdown at all.
+
+ If you have a system with several CPUs, you do not need to say Y
+ here: the IO-APIC will be used automatically.
+
+Local APIC Support on Uniprocessors
+CONFIG_X86_UP_APIC
+ A local APIC (Advanced Programmable Interrupt Controller) is an
+ integrated interrupt controller in the CPU. If you have a single-CPU
+ system which has a processor with a local APIC, you can say Y here to
+ enable and use it. If you say Y here even though your machine doesn't
+ have a local APIC, then the kernel will still run with no slowdown at
+ all. The local APIC supports CPU-generated self-interrupts (timer,
+ performance counters), and the NMI watchdog which detects hard lockups.
+
+ If you have a system with several CPUs, you do not need to say Y
+ here: the local APIC will be used automatically.

+Tainted kernels:
+
+Some oops reports contain the string 'Tainted: ' after the program
+counter, this indicates that the kernel has been tainted by some
+mechanism. The string is followed by a series of position sensitive
+characters, each representing a particular tainted value.
+
+ 1: 'G' if all modules loaded have a GPL or compatible license, 'P' if
+ any proprietary module has been loaded. Modules without a
+ MODULE_LICENSE or with a MODULE_LICENSE that is not recognised by
+ insmod as GPL compatible are assumed to be proprietary.
+
+ 2: 'F' if any module was force loaded by insmod -f, ' ' if all
+ modules were loaded normally.
+
+The primary reason for the 'Tainted: ' string is to tell kernel
+debuggers if this is a clean kernel or if anything unusual has
+occurred. Tainting is permanent, even if an offending module is
+unloading the tainted value remains to indicate that the kernel is not
+trustworthy.

--- /dev/null
+Module options
+--------------
+
+The mwave module takes the following options. Note that these options
+are not saved by the BIOS and so do not persist after unload and reload.
+
+ mwave_debug=value, where value is bitwise OR of trace flags:
+ 0x0001 mwavedd api tracing
+ 0x0002 smapi api tracing
+ 0x0004 3780i tracing
+ 0x0008 tp3780i tracing
+
+ Tracing only occurs if the driver has been compiled with the
+ MW_TRACE macro #defined (i.e. let EXTRA_CFLAGS += -DMW_TRACE
+ in the Makefile).
+
+ mwave_3780i_irq=5/7/10/11/15
+ If the dsp irq has not been setup and stored in bios by the
+ thinkpad configuration utility then this parameter allows the
+ irq used by the dsp to be configured.
+
+ mwave_3780i_io=0x130/0x350/0x0070/0xDB0
+ If the dsp io range has not been setup and stored in bios by the
+ thinkpad configuration utility then this parameter allows the
+ io range used by the dsp to be configured.
+
+ mwave_uart_irq=3/4
+ If the mwave's uart irq has not been setup and stored in bios by the
+ thinkpad configuration utility then this parameter allows the
+ irq used by the mwave uart to be configured.
+
+ mwave_uart_io=0x3f8/0x2f8/0x3E8/0x2E8
+ If the uart io range has not been setup and stored in bios by the
+ thinkpad configuration utility then this parameter allows the
+ io range used by the mwave uart to be configured.
+
+Example to enable the 3780i DSP using ttyS1 resources:
+
+ insmod mwave mwave_3780i_irq=10 mwave_3780i_io=0x0130 mwave_uart_irq=3 mwave_uart_io=0x2f8
+
+Accessing the driver
+--------------------
+
+You must also create a node for the driver. Without devfs:
+ mkdir -p /dev/modems
+ mknod --mode=660 /dev/modems/mwave c 10 219
+With devfs:
+ mkdir -p /dev/modems
+ ln -s ../misc/mwave /dev/modems/mwave

- * An IUCV frame consists of one or more packets preceded by a 16-bit
- * header. The header contains the offset to the next packet header,
- * measured from the beginning of the _frame_. If zero, there are no more
- * packets in the frame. Consider a frame which contains a 10-byte packet
- * followed by a 20-byte packet:
- * +-----+----------------+--------------------------------+-----+
- * |h'12'| 10-byte packet |h'34'| 20-byte packet |h'00'|
- * +-----+----------------+-----+--------------------------+-----+
- * Offset: 0 2 12 14 34
+ * You should have received a copy of the GNU General Public License
+ * along with this program; if not, write to the Free Software
+ * Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
*
- * This means that each header will always have a larger value than the
- * previous one (except for the final zero header, of course).
- *
- * For outbound packets, we send ONE frame per packet. So, our frame is:
- * AL2(packet length+2), packet, AL2(0)
- * The maximum packet size is the MTU, so the maximum IUCV frame we send
- * is MTU+4 bytes.
+ * RELEASE-TAG: IUCV network driver $Revision: 1.11 $
*
- * For inbound frames, we don't care how long the frame is. We tear apart
- * the frame, processing packets up to MTU size in length, until no more
- * packets remain in the frame.
- *
- * --------------------------------------------------------------------------
- * The code uses the 2.3.43 network driver interfaces. If compiled on an
- * an older level of the kernel, the module provides its own macros.
- * Doc is in Linux Weekly News (lwn.net) memo from David Miller, 9 Feb 2000.
- * There are a few other places with 2.3-specific enhancements.

+# 23/09/2001 - Added support for typedefs, structs, enums and unions
+# Support for Context section; can be terminated using empty line
+# Small fixes (like spaces vs. \s in regex)
+# -- Tim Jansen <tim@tjansen.de>
+

# style of gnome comments (+minor extensions - see below).

# etc.
#
-# All descriptions can be multiline, apart from the short function description.
+# Beside functions you can also write documentation for structs, unions,
+# enums and typedefs. Instead of the function name you must write the name
+# of the declaration; the struct/union/enum/typedef must always precede
+# the name. Nesting of declarations is not supported.
+# Use the argument mechanism to document members or constants. In
+# structs and unions you must declare one member per declaration
+# (comma-separated members are not allowed - the parser does not support
+# this).
+# e.g.
+# /**
+# * struct my_struct - short description
+# * @a: first member
+# * @b: second member
+# *
+# * Longer description
+# */
+# struct my_struct {
+# int a;
+# int b;
+# };
+#
+# All descriptions can be multiline, except the short function description.
+#
+# You can also add additional sections. When documenting kernel functions you
+# should document the "Context:" of the function, e.g. whether the functions
+# can be called form interrupts. Unlike other sections you can end it with an
+# empty line.
+# Example-sections should contain the string EXAMPLE so that they are marked
+# appropriately in DocBook.
+#
+# Example:
+# /**
+# * user_function - function that can only be called in user context
+# * @a: some argument
+# * Context: !in_interrupt()
+# *
+# * Some description
+# * Example:
+# * user_function(22);
