+
+1 INTRODUCTION
+
+The async_tx API provides methods for describing a chain of asynchronous
+bulk memory transfers/transforms with support for inter-transactional
+dependencies. It is implemented as a dmaengine client that smooths over
+the details of different hardware offload engine implementations. Code
+that is written to the API can optimize for asynchronous operation and
+the API will fit the chain of operations to the available offload
+resources.
+
+2 GENEALOGY
+
+The API was initially designed to offload the memory copy and
+xor-parity-calculations of the md-raid5 driver using the offload engines
+present in the Intel(R) Xscale series of I/O processors. It also built
+on the 'dmaengine' layer developed for offloading memory copies in the
+network stack using Intel(R) I/OAT engines. The following design
+features surfaced as a result:
+1/ implicit synchronous path: users of the API do not need to know if
+ the platform they are running on has offload capabilities. The
+ operation will be offloaded when an engine is available and carried out
+ in software otherwise.
+2/ cross channel dependency chains: the API allows a chain of dependent
+ operations to be submitted, like xor->copy->xor in the raid5 case. The
+ API automatically handles cases where the transition from one operation
+ to another implies a hardware channel switch.
+3/ dmaengine extensions to support multiple clients and operation types
+ beyond 'memcpy'
+
+3 USAGE
+
+3.1 General format of the API:
+struct dma_async_tx_descriptor *
+async_<operation>(<op specific parameters>,
+ enum async_tx_flags flags,
+ struct dma_async_tx_descriptor *dependency,
+ dma_async_tx_callback callback_routine,
+ void *callback_parameter);
+
+3.2 Supported operations:
+memcpy - memory copy between a source and a destination buffer
+memset - fill a destination buffer with a byte value
+xor - xor a series of source buffers and write the result to a
+ destination buffer
+xor_zero_sum - xor a series of source buffers and set a flag if the
+ result is zero. The implementation attempts to prevent
+ writes to memory
+
+3.3 Descriptor management:
+The return value is non-NULL and points to a 'descriptor' when the operation
+has been queued to execute asynchronously. Descriptors are recycled
+resources, under control of the offload engine driver, to be reused as
+operations complete. When an application needs to submit a chain of
+operations it must guarantee that the descriptor is not automatically recycled
+before the dependency is submitted. This requires that all descriptors be
+acknowledged by the application before the offload engine driver is allowed to
+recycle (or free) the descriptor. A descriptor can be acked by one of the
+following methods:
+1/ setting the ASYNC_TX_ACK flag if no child operations are to be submitted
+2/ setting the ASYNC_TX_DEP_ACK flag to acknowledge the parent
+ descriptor of a new operation.
+3/ calling async_tx_ack() on the descriptor.
+
+3.4 When does the operation execute?
+Operations do not immediately issue after return from the
+async_<operation> call. Offload engine drivers batch operations to
+improve performance by reducing the number of mmio cycles needed to
+manage the channel. Once a driver-specific threshold is met the driver
+automatically issues pending operations. An application can force this
+event by calling async_tx_issue_pending_all(). This operates on all
+channels since the application has no knowledge of channel to operation
+mapping.
+
+3.5 When does the operation complete?
+There are two methods for an application to learn about the completion
+of an operation.
+1/ Call dma_wait_for_async_tx(). This call causes the CPU to spin while
+ it polls for the completion of the operation. It handles dependency
+ chains and issuing pending operations.
+2/ Specify a completion callback. The callback routine runs in tasklet
+ context if the offload engine driver supports interrupts, or it is
+ called in application context if the operation is carried out
+ synchronously in software. The callback can be set in the call to
+ async_<operation>, or when the application needs to submit a chain of
+ unknown length it can use the async_trigger_callback() routine to set a
+ completion interrupt/callback at the end of the chain.
+
+3.6 Constraints:
+1/ Calls to async_<operation> are not permitted in IRQ context. Other
+ contexts are permitted provided constraint #2 is not violated.
+2/ Completion callback routines cannot submit new operations. This
+ results in recursion in the synchronous case and spin_locks being
+ acquired twice in the asynchronous case.
+
+3.7 Example:
+Perform a xor->copy->xor operation where each operation depends on the
+result from the previous operation:
+
+void complete_xor_copy_xor(void *param)
+{
+ printk("complete\n");
+}
+
+int run_xor_copy_xor(struct page **xor_srcs,
+ int xor_src_cnt,
+ struct page *xor_dest,
+ size_t xor_len,
+ struct page *copy_src,
+ struct page *copy_dest,
+ size_t copy_len)
+{
+ struct dma_async_tx_descriptor *tx;
+
+ tx = async_xor(xor_dest, xor_srcs, 0, xor_src_cnt, xor_len,
+ ASYNC_TX_XOR_DROP_DST, NULL, NULL, NULL);
+ tx = async_memcpy(copy_dest, copy_src, 0, 0, copy_len,
+ ASYNC_TX_DEP_ACK, tx, NULL, NULL);
+ tx = async_xor(xor_dest, xor_srcs, 0, xor_src_cnt, xor_len,
+ ASYNC_TX_XOR_DROP_DST | ASYNC_TX_DEP_ACK | ASYNC_TX_ACK,
+ tx, complete_xor_copy_xor, NULL);
+
+ async_tx_issue_pending_all();
+}
+
+See include/linux/async_tx.h for more information on the flags. See the
+ops_run_* and ops_complete_* routines in drivers/md/raid5.c for more
+implementation examples.
+
+4 DRIVER DEVELOPMENT NOTES
+4.1 Conformance points:
+There are a few conformance points required in dmaengine drivers to
+accommodate assumptions made by applications using the async_tx API:
+1/ Completion callbacks are expected to happen in tasklet context
+2/ dma_async_tx_descriptor fields are never manipulated in IRQ context
+3/ Use async_tx_run_dependencies() in the descriptor clean up path to
+ handle submission of dependent operations
+
+4.2 "My application needs finer control of hardware channels"
+This requirement seems to arise from cases where a DMA engine driver is
+trying to support device-to-memory DMA. The dmaengine and async_tx
+implementations were designed for offloading memory-to-memory
+operations; however, there are some capabilities of the dmaengine layer
+that can be used for platform-specific channel management.
+Platform-specific constraints can be handled by registering the
+application as a 'dma_client' and implementing a 'dma_event_callback' to
+apply a filter to the available channels in the system. Before showing
+how to implement a custom dma_event callback some background of
+dmaengine's client support is required.
+
+The following routines in dmaengine support multiple clients requesting
+use of a channel:
+- dma_async_client_register(struct dma_client *client)
+- dma_async_client_chan_request(struct dma_client *client)
+
+dma_async_client_register takes a pointer to an initialized dma_client
+structure. It expects that the 'event_callback' and 'cap_mask' fields
+are already initialized.
+
+dma_async_client_chan_request triggers dmaengine to notify the client of
+all channels that satisfy the capability mask. It is up to the client's
+event_callback routine to track how many channels the client needs and
+how many it is currently using. The dma_event_callback routine returns a
+dma_state_client code to let dmaengine know the status of the
+allocation.
+
+Below is the example of how to extend this functionality for
+platform-specific filtering of the available channels beyond the
+standard capability mask:
+
+static enum dma_state_client
+my_dma_client_callback(struct dma_client *client,
+ struct dma_chan *chan, enum dma_state state)
+{
+ struct dma_device *dma_dev;
+ struct my_platform_specific_dma *plat_dma_dev;
+
+ dma_dev = chan->device;
+ plat_dma_dev = container_of(dma_dev,
+ struct my_platform_specific_dma,
+ dma_dev);
+
+ if (!plat_dma_dev->platform_specific_capability)
+ return DMA_DUP;
+
+ . . .
+}

+** Introduction
+This document describes what I managed to discover about the protocol used to
+specify force effects to I-Force 2.0 devices. None of this information comes
+from Immerse. That's why you should not trust what is written in this
+document. This document is intended to help understanding the protocol.
+This is not a reference. Comments and corrections are welcome. To contact me,
+send an email to: deneux@ifrance.com
+
+** WARNING **
+I may not be held responsible for any dammage or harm caused if you try to
+send data to your I-Force device based on what you read in this document.
+
+** Preliminary Notes:
+All values are hexadecimal with big-endian encoding (msb on the left). Beware,
+values inside packets are encoded using little-endian. Bytes whose roles are
+unknown are marked ??? Information that needs deeper inspection is marked (?)
+
+** General form of a packet **
+This is how packets look when the device uses the rs232 to communicate.
+2B OP LEN DATA CS
+CS is the checksum. It is equal to the exclusive or of all bytes.
+
+When using USB:
+OP DATA
+The 2B, LEN and CS fields have disappeared, probably because USB handles frames and
+data corruption is handled or unsignificant.
+
+First, I describe effects that are sent by the device to the computer
+
+** Device input state
+This packet is used to indicate the state of each button and the value of each
+axis
+OP= 01 for a joystick, 03 for a wheel
+LEN= Varies from device to device
+00 X-Axis lsb
+01 X-Axis msb
+02 Y-Axis lsb, or gas pedal for a wheel
+03 Y-Axis msb, or brake pedal for a wheel
+04 Throttle
+05 Buttons
+06 Lower 4 bits: Buttons
+ Upper 4 bits: Hat
+07 Rudder
+
+** Device effects states
+OP= 02
+LEN= Varies
+00 ? Bit 1 (Value 2) is the value of the deadman switch
+01 Bit 8 is set if the effect is playing. Bits 0 to 7 are the effect id.
+02 ??
+03 Address of parameter block changed (lsb)
+04 Address of parameter block changed (msb)
+05 Address of second parameter block changed (lsb)
+... depending on the number of parameter blocks updated
+
+** Force effect **
+OP= 01
+LEN= 0e
+00 Channel (when playing several effects at the same time, each must be assigned a channel)

+ Val 23 Sawtooth up
+ Val 24 Sawtooth down
+ Val 40 Spring (Force = f(pos))
+ Val 41 Friction (Force = f(velocity)) and Inertia (Force = f(acceleration))
+
+
+02 Axes affected and trigger
+ Bits 4-7: Val 2 = effect along one axis. Byte 05 indicates direction
+ Val 4 = X axis only. Byte 05 must contain 5a
+ Val 8 = Y axis only. Byte 05 must contain b4
+ Val c = X and Y axes. Bytes 05 must contain 60
+ Bits 0-3: Val 0 = No trigger
+ Val x+1 = Button x triggers the effect
+ When the whole byte is 0, cancel the previously set trigger
+
+03-04 Duration of effect (little endian encoding, in ms)
+
+05 Direction of effect, if applicable. Else, see 02 for value to assign.
+
+06-07 Minimum time between triggering.

+LOCK STATISTICS
+
+- WHAT
+
+As the name suggests, it provides statistics on locks.
+
+- WHY
+
+Because things like lock contention can severely impact performance.
+
+- HOW
+
+Lockdep already has hooks in the lock functions and maps lock instances to
+lock classes. We build on that. The graph below shows the relation between
+the lock functions and the various hooks therein.
+
+ __acquire
+ |
+ lock _____
+ | \
+ | __contended
+ | |
+ | <wait>
+ | _______/
+ |/
+ |
+ __acquired
+ |
+ .
+ <hold>
+ .
+ |
+ __release
+ |
+ unlock
+
+lock, unlock - the regular lock functions
+__* - the hooks
+<> - states
+
+With these hooks we provide the following statistics:
+
+ con-bounces - number of lock contention that involved x-cpu data
+ contentions - number of lock acquisitions that had to wait
+ wait time min - shortest (non-0) time we ever had to wait for a lock
+ max - longest time we ever had to wait for a lock
+ total - total time we spend waiting on this lock
+ acq-bounces - number of lock acquisitions that involved x-cpu data
+ acquisitions - number of times we took the lock
+ hold time min - shortest (non-0) time we ever held the lock
+ max - longest time we ever held the lock
+ total - total time this lock was held
+
+From these number various other statistics can be derived, such as:
+
+ hold time average = hold time total / acquisitions
+
+These numbers are gathered per lock class, per read/write state (when
+applicable).
+
+It also tracks 4 contention points per class. A contention point is a call site
+that had to wait on lock acquisition.
+
+ - USAGE
+
+Look at the current lock statistics:

+
+This excerpt shows the first two lock class statistics. Line 01 shows the
+output version - each time the format changes this will be updated. Line 02-04
+show the header with column descriptions. Lines 05-10 and 13-18 show the actual
+statistics. These statistics come in two parts; the actual stats separated by a
+short separator (line 08, 14) from the contention points.
+
+The first lock (05-10) is a read/write lock, and shows two lines above the
+short separator. The contention points don't match the column descriptors,
+they have two: contentions and [<IP>] symbol.

+===========================================================================
+
+
+1 Overview
+===========
+
+The sk98lin driver supports the Marvell Yukon and SysKonnect
+SK-98xx/SK-95xx compliant Gigabit Ethernet Adapter on Linux. It has
+been tested with Linux on Intel/x86 machines.
+***
+
+
+2 Required Files
+=================
+
+The linux kernel source.
+No additional files required.
+***
+
+
+3 Installation
+===============
+
+It is recommended to download the latest version of the driver from the
+SysKonnect web site www.syskonnect.com. If you have downloaded the latest
+driver, the Linux kernel has to be patched before the driver can be
+installed. For details on how to patch a Linux kernel, refer to the
+patch.txt file.
+
+3.1 Driver Installation
+------------------------
+
+The following steps describe the actions that are required to install
+the driver and to start it manually. These steps should be carried
+out for the initial driver setup. Once confirmed to be ok, they can
+be included in the system start.
+
+NOTE 1: To perform the following tasks you need 'root' access.
+
+NOTE 2: In case of problems, please read the section "Troubleshooting"
+ below.
+
+The driver can either be integrated into the kernel or it can be compiled
+as a module. Select the appropriate option during the kernel
+configuration.
+
+Compile/use the driver as a module
+----------------------------------
+To compile the driver, go to the directory /usr/src/linux and
+execute the command "make menuconfig" or "make xconfig" and proceed as
+follows:
+
+To integrate the driver permanently into the kernel, proceed as follows:
+
+1. Select the menu "Network device support" and then "Ethernet(1000Mbit)"
+2. Mark "Marvell Yukon Chipset / SysKonnect SK-98xx family support"
+ with (*)
+3. Build a new kernel when the configuration of the above options is
+ finished.
+4. Install the new kernel.
+5. Reboot your system.
+
+To use the driver as a module, proceed as follows:
+
+1. Enable 'loadable module support' in the kernel.
+2. For automatic driver start, enable the 'Kernel module loader'.
+3. Select the menu "Network device support" and then "Ethernet(1000Mbit)"
+4. Mark "Marvell Yukon Chipset / SysKonnect SK-98xx family support"
+ with (M)
+5. Execute the command "make modules".
+6. Execute the command "make modules_install".
+ The appropriate modules will be installed.
+7. Reboot your system.
+
+
+Load the module manually
+------------------------
+To load the module manually, proceed as follows:
+
+1. Enter "modprobe sk98lin".
+2. If a Marvell Yukon or SysKonnect SK-98xx adapter is installed in
+ your computer and you have a /proc file system, execute the command:
+ "ls /proc/net/sk98lin/"
+ This should produce an output containing a line with the following
+ format:
+ eth0 eth1 ...
+ which indicates that your adapter has been found and initialized.
+
+ NOTE 1: If you have more than one Marvell Yukon or SysKonnect SK-98xx
+ adapter installed, the adapters will be listed as 'eth0',
+ 'eth1', 'eth2', etc.
+ For each adapter, repeat steps 3 and 4 below.
+
+ NOTE 2: If you have other Ethernet adapters installed, your Marvell
+ Yukon or SysKonnect SK-98xx adapter will be mapped to the
+ next available number, e.g. 'eth1'. The mapping is executed
+ automatically.
+ The module installation message (displayed either in a system
+ log file or on the console) prints a line for each adapter
+ found containing the corresponding 'ethX'.
+
+3. Select an IP address and assign it to the respective adapter by
+ entering:
+ ifconfig eth0 <ip-address>
+ With this command, the adapter is connected to the Ethernet.
+
+ SK-98xx Gigabit Ethernet Server Adapters: The yellow LED on the adapter
+ is now active, the link status LED of the primary port is active and
+ the link status LED of the secondary port (on dual port adapters) is
+ blinking (if the ports are connected to a switch or hub).
+ SK-98xx V2.0 Gigabit Ethernet Adapters: The link status LED is active.
+ In addition, you will receive a status message on the console stating
+ "ethX: network connection up using port Y" and showing the selected
+ connection parameters (x stands for the ethernet device number
+ (0,1,2, etc), y stands for the port name (A or B)).
+
+ NOTE: If you are in doubt about IP addresses, ask your network
+ administrator for assistance.
+
+4. Your adapter should now be fully operational.
+ Use 'ping <otherstation>' to verify the connection to other computers
+ on your network.
+5. To check the adapter configuration view /proc/net/sk98lin/[devicename].
+ For example by executing:
+ "cat /proc/net/sk98lin/eth0"
+
+Unload the module
+-----------------
+To stop and unload the driver modules, proceed as follows:
+
+1. Execute the command "ifconfig eth0 down".
+2. Execute the command "rmmod sk98lin".
+
+3.2 Inclusion of adapter at system start
+-----------------------------------------
+
+Since a large number of different Linux distributions are
+available, we are unable to describe a general installation procedure
+for the driver module.
+Because the driver is now integrated in the kernel, installation should
+be easy, using the standard mechanism of your distribution.
+Refer to the distribution's manual for installation of ethernet adapters.
+
+***
+
+4 Driver Parameters
+====================
+
+Parameters can be set at the command line after the module has been
+loaded with the command 'modprobe'.
+In some distributions, the configuration tools are able to pass parameters
+to the driver module.
+
+If you use the kernel module loader, you can set driver parameters
+in the file /etc/modprobe.conf (or /etc/modules.conf in 2.4 or earlier).
+To set the driver parameters in this file, proceed as follows:
+
+1. Insert a line of the form :
+ options sk98lin ...
+ For "...", the same syntax is required as described for the command
+ line parameters of modprobe below.
+2. To activate the new parameters, either reboot your computer
+ or
+ unload and reload the driver.
+ The syntax of the driver parameters is:
+
+ modprobe sk98lin parameter=value1[,value2[,value3...]]
+
+ where value1 refers to the first adapter, value2 to the second etc.
+
+NOTE: All parameters are case sensitive. Write them exactly as shown
+ below.
+
+Example:
+Suppose you have two adapters. You want to set auto-negotiation
+on the first adapter to ON and on the second adapter to OFF.
+You also want to set DuplexCapabilities on the first adapter
+to FULL, and on the second adapter to HALF.
+Then, you must enter:
+
+ modprobe sk98lin AutoNeg_A=On,Off DupCap_A=Full,Half
+
+NOTE: The number of adapters that can be configured this way is
+ limited in the driver (file skge.c, constant SK_MAX_CARD_PARAM).
+ The current limit is 16. If you happen to install
+ more adapters, adjust this and recompile.
+
+
+4.1 Per-Port Parameters
+------------------------
+
+These settings are available for each port on the adapter.
+In the following description, '?' stands for the port for
+which you set the parameter (A or B).
+
+Speed
+-----
+Parameter: Speed_?
+Values: 10, 100, 1000, Auto
+Default: Auto
+
+This parameter is used to set the speed capabilities. It is only valid
+for the SK-98xx V2.0 copper adapters.
+Usually, the speed is negotiated between the two ports during link
+establishment. If this fails, a port can be forced to a specific setting
+with this parameter.
+
+Auto-Negotiation
+----------------
+Parameter: AutoNeg_?
+Values: On, Off, Sense
+Default: On
+
+The "Sense"-mode automatically detects whether the link partner supports
+auto-negotiation or not.
+
+Duplex Capabilities
+-------------------
+Parameter: DupCap_?
+Values: Half, Full, Both
+Default: Both
+
+This parameters is only relevant if auto-negotiation for this port is
+not set to "Sense". If auto-negotiation is set to "On", all three values
+are possible. If it is set to "Off", only "Full" and "Half" are allowed.
+This parameter is useful if your link partner does not support all
+possible combinations.
+
+Flow Control
+------------
+Parameter: FlowCtrl_?
+Values: Sym, SymOrRem, LocSend, None
+Default: SymOrRem
+
+This parameter can be used to set the flow control capabilities the
+port reports during auto-negotiation. It can be set for each port
+individually.
+Possible modes:
+ -- Sym = Symmetric: both link partners are allowed to send
+ PAUSE frames
+ -- SymOrRem = SymmetricOrRemote: both or only remote partner
+ are allowed to send PAUSE frames
+ -- LocSend = LocalSend: only local link partner is allowed
+ to send PAUSE frames
+ -- None = no link partner is allowed to send PAUSE frames
+
+NOTE: This parameter is ignored if auto-negotiation is set to "Off".
+
+Role in Master-Slave-Negotiation (1000Base-T only)
+--------------------------------------------------
+Parameter: Role_?
+Values: Auto, Master, Slave
+Default: Auto
+
+This parameter is only valid for the SK-9821 and SK-9822 adapters.
+For two 1000Base-T ports to communicate, one must take the role of the
+master (providing timing information), while the other must be the
+slave. Usually, this is negotiated between the two ports during link
+establishment. If this fails, a port can be forced to a specific setting
+with this parameter.
+
+
+4.2 Adapter Parameters
+-----------------------
+
+Connection Type (SK-98xx V2.0 copper adapters only)
+---------------
+Parameter: ConType
+Values: Auto, 100FD, 100HD, 10FD, 10HD
+Default: Auto
+
+The parameter 'ConType' is a combination of all five per-port parameters
+within one single parameter. This simplifies the configuration of both ports
+of an adapter card! The different values of this variable reflect the most
+meaningful combinations of port parameters.
+
+The following table shows the values of 'ConType' and the corresponding
+combinations of the per-port parameters:
+
+ ConType | DupCap AutoNeg FlowCtrl Role Speed
+ ----------+------------------------------------------------------
+ Auto | Both On SymOrRem Auto Auto
+ 100FD | Full Off None Auto (ignored) 100
+ 100HD | Half Off None Auto (ignored) 100
+ 10FD | Full Off None Auto (ignored) 10
+ 10HD | Half Off None Auto (ignored) 10
+
+Stating any other port parameter together with this 'ConType' variable
+will result in a merged configuration of those settings. This due to
+the fact, that the per-port parameters (e.g. Speed_? ) have a higher
+priority than the combined variable 'ConType'.
+
+NOTE: This parameter is always used on both ports of the adapter card.
+
+Interrupt Moderation
+--------------------
+Parameter: Moderation
+Values: None, Static, Dynamic
+Default: None
+
+Interrupt moderation is employed to limit the maximum number of interrupts
+the driver has to serve. That is, one or more interrupts (which indicate any
+transmit or receive packet to be processed) are queued until the driver
+processes them. When queued interrupts are to be served, is determined by the
+'IntsPerSec' parameter, which is explained later below.
+
+Possible modes:
+
+ -- None - No interrupt moderation is applied on the adapter card.
+ Therefore, each transmit or receive interrupt is served immediately
+ as soon as it appears on the interrupt line of the adapter card.
+
+ -- Static - Interrupt moderation is applied on the adapter card.
+ All transmit and receive interrupts are queued until a complete
+ moderation interval ends. If such a moderation interval ends, all
+ queued interrupts are processed in one big bunch without any delay.
+ The term 'static' reflects the fact, that interrupt moderation is
+ always enabled, regardless how much network load is currently
+ passing via a particular interface. In addition, the duration of
+ the moderation interval has a fixed length that never changes while
+ the driver is operational.
+
+ -- Dynamic - Interrupt moderation might be applied on the adapter card,
+ depending on the load of the system. If the driver detects that the
+ system load is too high, the driver tries to shield the system against
+ too much network load by enabling interrupt moderation. If - at a later
+ time - the CPU utilization decreases again (or if the network load is
+ negligible) the interrupt moderation will automatically be disabled.
+
+Interrupt moderation should be used when the driver has to handle one or more
+interfaces with a high network load, which - as a consequence - leads also to a
+high CPU utilization. When moderation is applied in such high network load
+situations, CPU load might be reduced by 20-30%.
+
+NOTE: The drawback of using interrupt moderation is an increase of the round-
+trip-time (RTT), due to the queueing and serving of interrupts at dedicated
+moderation times.
+
+Interrupts per second
+---------------------
+Parameter: IntsPerSec
+Values: 30...40000 (interrupts per second)
+Default: 2000
+
+This parameter is only used if either static or dynamic interrupt moderation
+is used on a network adapter card. Using this parameter if no moderation is
+applied will lead to no action performed.
+
+This parameter determines the length of any interrupt moderation interval.
+Assuming that static interrupt moderation is to be used, an 'IntsPerSec'
+parameter value of 2000 will lead to an interrupt moderation interval of
+500 microseconds.
+
+NOTE: The duration of the moderation interval is to be chosen with care.
+At first glance, selecting a very long duration (e.g. only 100 interrupts per
+second) seems to be meaningful, but the increase of packet-processing delay
+is tremendous. On the other hand, selecting a very short moderation time might
+compensate the use of any moderation being applied.
+
+
+Preferred Port
+--------------
+Parameter: PrefPort
+Values: A, B
+Default: A
+
+This is used to force the preferred port to A or B (on dual-port network
+adapters). The preferred port is the one that is used if both are detected
+as fully functional.
+
+RLMT Mode (Redundant Link Management Technology)
+------------------------------------------------
+Parameter: RlmtMode
+Values: CheckLinkState,CheckLocalPort, CheckSeg, DualNet
+Default: CheckLinkState
+
+RLMT monitors the status of the port. If the link of the active port
+fails, RLMT switches immediately to the standby link. The virtual link is
+maintained as long as at least one 'physical' link is up.
+
+Possible modes:
+
+ -- CheckLinkState - Check link state only: RLMT uses the link state
+ reported by the adapter hardware for each individual port to
+ determine whether a port can be used for all network traffic or
+ not.
+
+ -- CheckLocalPort - In this mode, RLMT monitors the network path
+ between the two ports of an adapter by regularly exchanging packets
+ between them. This mode requires a network configuration in which
+ the two ports are able to "see" each other (i.e. there must not be
+ any router between the ports).
+
+ -- CheckSeg - Check local port and segmentation: This mode supports the
+ same functions as the CheckLocalPort mode and additionally checks
+ network segmentation between the ports. Therefore, this mode is only
+ to be used if Gigabit Ethernet switches are installed on the network
+ that have been configured to use the Spanning Tree protocol.
+
+ -- DualNet - In this mode, ports A and B are used as separate devices.
+ If you have a dual port adapter, port A will be configured as eth0
+ and port B as eth1. Both ports can be used independently with
+ distinct IP addresses. The preferred port setting is not used.
+ RLMT is turned off.
+
+NOTE: RLMT modes CLP and CLPSS are designed to operate in configurations
+ where a network path between the ports on one adapter exists.
+ Moreover, they are not designed to work where adapters are connected
+ back-to-back.
+***
+
+
+5 Large Frame Support
+======================
+
+The driver supports large frames (also called jumbo frames). Using large
+frames can result in an improved throughput if transferring large amounts
+of data.
+To enable large frames, set the MTU (maximum transfer unit) of the
+interface to the desired value (up to 9000), execute the following
+command:
+ ifconfig eth0 mtu 9000
+This will only work if you have two adapters connected back-to-back
+or if you use a switch that supports large frames. When using a switch,
+it should be configured to allow large frames and auto-negotiation should
+be set to OFF. The setting must be configured on all adapters that can be
+reached by the large frames. If one adapter is not set to receive large
+frames, it will simply drop them.
+
+You can switch back to the standard ethernet frame size by executing the
+following command:
+ ifconfig eth0 mtu 1500
+
+To permanently configure this setting, add a script with the 'ifconfig'
+line to the system startup sequence (named something like "S99sk98lin"
+in /etc/rc.d/rc2.d).
+***
+
+
+6 VLAN and Link Aggregation Support (IEEE 802.1, 802.1q, 802.3ad)
+==================================================================
+
+The Marvell Yukon/SysKonnect Linux drivers are able to support VLAN and
+Link Aggregation according to IEEE standards 802.1, 802.1q, and 802.3ad.
+These features are only available after installation of open source
+modules available on the Internet:
+For VLAN go to: http://www.candelatech.com/~greear/vlan.html
+For Link Aggregation go to: http://www.st.rim.or.jp/~yumo
+
+NOTE: SysKonnect GmbH does not offer any support for these open source
+ modules and does not take the responsibility for any kind of
+ failures or problems arising in connection with these modules.
+
+NOTE: Configuring Link Aggregation on a SysKonnect dual link adapter may
+ cause problems when unloading the driver.
+
+
+7 Troubleshooting
+==================
+
+If any problems occur during the installation process, check the
+following list:
+
+
+Problem: The SK-98xx adapter cannot be found by the driver.
+Solution: In /proc/pci search for the following entry:
+ 'Ethernet controller: SysKonnect SK-98xx ...'
+ If this entry exists, the SK-98xx or SK-98xx V2.0 adapter has
+ been found by the system and should be operational.
+ If this entry does not exist or if the file '/proc/pci' is not
+ found, there may be a hardware problem or the PCI support may
+ not be enabled in your kernel.
+ The adapter can be checked using the diagnostics program which
+ is available on the SysKonnect web site:
+ www.syskonnect.com
+
+ Some COMPAQ machines have problems dealing with PCI under Linux.
+ This problem is described in the 'PCI howto' document
+ (included in some distributions or available from the
+ web, e.g. at 'www.linux.org').
+
+
+Problem: Programs such as 'ifconfig' or 'route' cannot be found or the
+ error message 'Operation not permitted' is displayed.
+Reason: You are not logged in as user 'root'.
+Solution: Logout and login as 'root' or change to 'root' via 'su'.
+
+
+Problem: Upon use of the command 'ping <address>' the message
+ "ping: sendto: Network is unreachable" is displayed.
+Reason: Your route is not set correctly.
+Solution: If you are using RedHat, you probably forgot to set up the
+ route in the 'network configuration'.
+ Check the existing routes with the 'route' command and check
+ if an entry for 'eth0' exists, and if so, if it is set correctly.
+
+
+Problem: The driver can be started, the adapter is connected to the
+ network, but you cannot receive or transmit any packets;
+ e.g. 'ping' does not work.
+Reason: There is an incorrect route in your routing table.
+Solution: Check the routing table with the command 'route' and read the
+ manual help pages dealing with routes (enter 'man route').
+
+NOTE: Although the 2.2.x kernel versions generate the routing entry
+ automatically, problems of this kind may occur here as well. We've
+ come across a situation in which the driver started correctly at
+ system start, but after the driver has been removed and reloaded,
+ the route of the adapter's network pointed to the 'dummy0'device
+ and had to be corrected manually.
+
+
+Problem: Your computer should act as a router between multiple
+ IP subnetworks (using multiple adapters), but computers in
+ other subnetworks cannot be reached.
+Reason: Either the router's kernel is not configured for IP forwarding
+ or the routing table and gateway configuration of at least one
+ computer is not working.
+
+Problem: Upon driver start, the following error message is displayed:
+ "eth0: -- ERROR --
+ Class: internal Software error
+ Nr: 0xcc
+ Msg: SkGeInitPort() cannot init running ports"
+Reason: You are using a driver compiled for single processor machines
+ on a multiprocessor machine with SMP (Symmetric MultiProcessor)
+ kernel.
+Solution: Configure your kernel appropriately and recompile the kernel or
+ the modules.
+
+
+
+If your problem is not listed here, please contact SysKonnect's technical
+support for help (linux@syskonnect.de).
+When contacting our technical support, please ensure that the following
+information is available:
+- System Manufacturer and HW Informations (CPU, Memory... )
+- PCI-Boards in your system
+- Distribution
+- Kernel version
+- Driver version

Non hot-key ACPI HKEY event map:
0x5001 Lid closed
0x5002 Lid opened
0x7000 Radio Switch may have changed state
+The above events are not propagated by the driver, except for legacy
+compatibility purposes when hotkey_report_mode is set to 1.
+
+Compatibility notes:
+
+ibm-acpi and thinkpad-acpi 0.15 (mainline kernels before 2.6.23) never
+supported the input layer, and sent events over the procfs ACPI event
+interface.
+
+To avoid sending duplicate events over the input layer and the ACPI
+event interface, thinkpad-acpi 0.16 implements a module parameter
+(hotkey_report_mode), and also a sysfs device attribute with the same
+name.
+
+Make no mistake here: userspace is expected to switch to using the input
+layer interface of thinkpad-acpi, together with the ACPI netlink event
+interface in kernels 2.6.23 and later, or with the ACPI procfs event
+interface in kernels 2.6.22 and earlier.
+
+If no hotkey_report_mode module parameter is specified (or it is set to
+zero), the driver defaults to mode 1 (see below), and on kernels 2.6.22
+and earlier, also allows one to change the hotkey_report_mode through
+sysfs. In kernels 2.6.23 and later, where the netlink ACPI event
+interface is available, hotkey_report_mode cannot be changed through
+sysfs (it is read-only).
+
+If the hotkey_report_mode module parameter is set to 1 or 2, it cannot
+be changed later through sysfs (any writes will return -EPERM to signal
+that hotkey_report_mode was locked. On 2.6.23 and later, where
+hotkey_report_mode cannot be changed at all, writes will return -EACES).
+
+hotkey_report_mode set to 1 makes the driver export through the procfs
+ACPI event interface all hot key presses (which are *also* sent to the
+input layer). This is a legacy compatibility behaviour, and it is also
+the default mode of operation for the driver.
+
+hotkey_report_mode set to 2 makes the driver filter out the hot key
+presses from the procfs ACPI event interface, so these events will only
+be sent through the input layer. Userspace that has been updated to use
+the thinkpad-acpi input layer interface should set hotkey_report_mode to
+2.
+
+Hot key press events are never sent to the ACPI netlink event interface.
+Really up-to-date userspace under kernel 2.6.23 and later is to use the
+netlink interface and the input layer interface, and don't bother at all
+with hotkey_report_mode.
