Kale - - - - - This file is licensed under the terms of the GNU General Public License - version 2. This program is licensed "as is" without any warranty of any - kind, whether express or implied. - - - - - - - - Introduction - - kgdb is a source level debugger for linux kernel. It is used along - with gdb to debug a linux kernel. The expectation is that gdb can - be used to "break in" to the kernel to inspect memory, variables - and look through a cal stack information similar to what an - application developer would use gdb for. It is possible to place - breakpoints in kernel code and perform some limited execution - stepping. - - - Two machines are required for using kgdb. One of these machines is a - development machine and the other is a test machine. The kernel - to be debugged runs on the test machine. The development machine - runs an instance of gdb against the vmlinux file which contains - the symbols (not boot image such as bzImage, zImage, uImage...). - In gdb the developer specifies the connection parameters and - connects to kgdb. Depending on which kgdb I/O modules exist in - the kernel for a given architecture, it may be possible to debug - the test machine's kernel with the development machine using a - rs232 or ethernet connection. - - - - Compiling a kernel - - To enable CONFIG_KGDB, look under the "Kernel debugging" - and then select "KGDB: kernel debugging with remote gdb". - - - Next you should choose one of more I/O drivers to interconnect debugging - host and debugged target. Early boot debugging requires a KGDB - I/O driver that supports early debugging and the driver must be - built into the kernel directly. Kgdb I/O driver configuration - takes place via kernel or module parameters, see following - chapter. - - - The kgdb test compile options are described in the kgdb test suite chapter. - - - - - Enable kgdb for debugging - - In order to use kgdb you must activate it by passing configuration - information to one of the kgdb I/O drivers. If you do not pass any - configuration information kgdb will not do anything at all. Kgdb - will only actively hook up to the kernel trap hooks if a kgdb I/O - driver is loaded and configured. If you unconfigure a kgdb I/O - driver, kgdb will unregister all the kernel hook points. - - - All drivers can be reconfigured at run time, if - CONFIG_SYSFS and CONFIG_MODULES - are enabled, by echo'ing a new config string to - /sys/module/<driver>/parameter/<option>. - The driver can be unconfigured by passing an empty string. You cannot - change the configuration while the debugger is attached. Make sure - to detach the debugger with the detach command - prior to trying unconfigure a kgdb I/O driver. - - - Kernel parameter: kgdbwait - - The Kernel command line option kgdbwait makes - kgdb wait for a debugger connection during booting of a kernel. You - can only use this option you compiled a kgdb I/O driver into the - kernel and you specified the I/O driver configuration as a kernel - command line option. The kgdbwait parameter should always follow the - configuration parameter for the kgdb I/O driver in the kernel - command line else the I/O driver will not be configured prior to - asking the kernel to use it to wait. - - - The kernel will stop and wait as early as the I/O driver and - architecture will allow when you use this option. If you build the - kgdb I/O driver as a kernel module kgdbwait will not do anything. - - - - Kernel parameter: kgdboc - - The kgdboc driver was originally an abbreviation meant to stand for - "kgdb over console". Kgdboc is designed to work with a single - serial port. It was meant to cover the circumstance - where you wanted to use a serial console as your primary console as - well as using it to perform kernel debugging. Of course you can - also use kgdboc without assigning a console to the same port. - - - Using kgdboc - - You can configure kgdboc via sysfs or a module or kernel boot line - parameter depending on if you build with CONFIG_KGDBOC as a module - or built-in. - - From the module load or build-in - kgdboc=<tty-device>,[baud] - - The example here would be if your console port was typically ttyS0, you would use something like kgdboc=ttyS0,115200 or on the ARM Versatile AB you would likely use kgdboc=ttyAMA0,115200 - - - From sysfs - echo ttyS0 > /sys/module/kgdboc/parameters/kgdboc - - - - - NOTE: Kgdboc does not support interrupting the target via the - gdb remote protocol. You must manually send a sysrq-g unless you - have a proxy that splits console output to a terminal problem and - has a separate port for the debugger to connect to that sends the - sysrq-g for you. - - When using kgdboc with no debugger proxy, you can end up - connecting the debugger for one of two entry points. If an - exception occurs after you have loaded kgdboc a message should print - on the console stating it is waiting for the debugger. In case you - disconnect your terminal program and then connect the debugger in - its place. If you want to interrupt the target system and forcibly - enter a debug session you have to issue a Sysrq sequence and then - type the letter g. Then you disconnect the - terminal session and connect gdb. Your options if you don't like - this are to hack gdb to send the sysrq-g for you as well as on the - initial connect, or to use a debugger proxy that allows an - unmodified gdb to do the debugging. - - - - - Kernel parameter: kgdbcon - - Kgdb supports using the gdb serial protocol to send console messages - to the debugger when the debugger is connected and running. There - are two ways to activate this feature. - - Activate with the kernel command line option: - kgdbcon - - Use sysfs before configuring an io driver - - echo 1 > /sys/module/kgdb/parameters/kgdb_use_con - - - NOTE: If you do this after you configure the kgdb I/O driver, the - setting will not take effect until the next point the I/O is - reconfigured. - - - - - - IMPORTANT NOTE: Using this option with kgdb over the console - (kgdboc) or kgdb over ethernet (kgdboe) is not supported. - - - - - Connecting gdb - - If you are using kgdboc, you need to have used kgdbwait as a boot - argument, issued a sysrq-g, or the system you are going to debug - has already taken an exception and is waiting for the debugger to - attach before you can connect gdb. - - - If you are not using different kgdb I/O driver other than kgdboc, - you should be able to connect and the target will automatically - respond. - - - Example (using a serial port): - - - % gdb ./vmlinux - (gdb) set remotebaud 115200 - (gdb) target remote /dev/ttyS0 - - - Example (kgdb to a terminal server): - - - % gdb ./vmlinux - (gdb) target remote udp:192.168.2.2:6443 - - - Example (kgdb over ethernet): - - - % gdb ./vmlinux - (gdb) target remote udp:192.168.2.2:6443 - - - Once connected, you can debug a kernel the way you would debug an - application program. - - - If you are having problems connecting or something is going - seriously wrong while debugging, it will most often be the case - that you want to enable gdb to be verbose about its target - communications. You do this prior to issuing the target - remote command by typing in: set remote debug 1 - - - - kgdb Test Suite - - When kgdb is enabled in the kernel config you can also elect to - enable the config parameter KGDB_TESTS. Turning this on will - enable a special kgdb I/O module which is designed to test the - kgdb internal functions. - - - The kgdb tests are mainly intended for developers to test the kgdb - internals as well as a tool for developing a new kgdb architecture - specific implementation. These tests are not really for end users - of the Linux kernel. The primary source of documentation would be - to look in the drivers/misc/kgdbts.c file. - - - The kgdb test suite can also be configured at compile time to run - the core set of tests by setting the kernel config parameter - KGDB_TESTS_ON_BOOT. This particular option is aimed at automated - regression testing and does not require modifying the kernel boot - config arguments. If this is turned on, the kgdb test suite can - be disabled by specifying "kgdbts=" as a kernel boot argument. - - - - KGDB Internals - - Architecture Specifics - - Kgdb is organized into three basic components: - - kgdb core - - The kgdb core is found in kernel/kgdb.c. It contains: - - All the logic to implement the gdb serial protocol - A generic OS exception handler which includes sync'ing the processors into a stopped state on an multi cpu system. - The API to talk to the kgdb I/O drivers - The API to make calls to the arch specific kgdb implementation - The logic to perform safe memory reads and writes to memory while using the debugger - A full implementation for software breakpoints unless overridden by the arch - - - - kgdb arch specific implementation - - This implementation is generally found in arch/*/kernel/kgdb.c. - As an example, arch/x86/kernel/kgdb.c contains the specifics to - implement HW breakpoint as well as the initialization to - dynamically register and unregister for the trap handlers on - this architecture. The arch specific portion implements: - - contains an arch specific trap catcher which - invokes kgdb_handle_exception() to start kgdb about doing its - work - translation to and from gdb specific packet format to pt_regs - Registration and unregistration of architecture specific trap hooks - Any special exception handling and cleanup - NMI exception handling and cleanup - (optional)HW breakpoints - - - - kgdb I/O driver - - Each kgdb I/O driver has to provide an implemenation for the following: - - configuration via builtin or module - dynamic configuration and kgdb hook registration calls - read and write character interface - A cleanup handler for unconfiguring from the kgdb core - (optional) Early debug methodology - - Any given kgdb I/O driver has to operate very closely with the - hardware and must do it in such a way that does not enable - interrupts or change other parts of the system context without - completely restoring them. The kgdb core will repeatedly "poll" - a kgdb I/O driver for characters when it needs input. The I/O - driver is expected to return immediately if there is no data - available. Doing so allows for the future possibility to touch - watch dog hardware in such a way as to have a target system not - reset when these are enabled. - - - - - - If you are intent on adding kgdb architecture specific support - for a new architecture, the architecture should define - HAVE_ARCH_KGDB in the architecture specific - Kconfig file. This will enable kgdb for the architecture, and - at that point you must create an architecture specific kgdb - implementation. - - - There are a few flags which must be set on every architecture in - their <asm/kgdb.h> file. These are: - - - - NUMREGBYTES: The size in bytes of all of the registers, so - that we can ensure they will all fit into a packet. - - - BUFMAX: The size in bytes of the buffer GDB will read into. - This must be larger than NUMREGBYTES. - - - CACHE_FLUSH_IS_SAFE: Set to 1 if it is always safe to call - flush_cache_range or flush_icache_range. On some architectures, - these functions may not be safe to call on SMP since we keep other - CPUs in a holding pattern. - - - - - - There are also the following functions for the common backend, - found in kernel/kgdb.c, that must be supplied by the - architecture-specific backend unless marked as (optional), in - which case a default function maybe used if the architecture - does not need to provide a specific implementation. - -!Iinclude/linux/kgdb.h - - - kgdboc internals - - The kgdboc driver is actually a very thin driver that relies on the - underlying low level to the hardware driver having "polling hooks" - which the to which the tty driver is attached. In the initial - implementation of kgdboc it the serial_core was changed to expose a - low level uart hook for doing polled mode reading and writing of a - single character while in an atomic context. When kgdb makes an I/O - request to the debugger, kgdboc invokes a call back in the serial - core which in turn uses the call back in the uart driver. It is - certainly possible to extend kgdboc to work with non-uart based - consoles in the future. - - - When using kgdboc with a uart, the uart driver must implement two callbacks in the struct uart_ops. Example from drivers/8250.c: -#ifdef CONFIG_CONSOLE_POLL - .poll_get_char = serial8250_get_poll_char, - .poll_put_char = serial8250_put_poll_char, -#endif - - Any implementation specifics around creating a polling driver use the - #ifdef CONFIG_CONSOLE_POLL, as shown above. - Keep in mind that polling hooks have to be implemented in such a way - that they can be called from an atomic context and have to restore - the state of the uart chip on return such that the system can return - to normal when the debugger detaches. You need to be very careful - with any kind of lock you consider, because failing here is most - going to mean pressing the reset button. - - - - - Credits - - The following people have contributed to this document: - - Amit Kaleamitkale@linsyssoft.com - Tom Rinitrini@kernel.crashing.org - - In March 2008 this document was completely rewritten by: - - Jason Wesseljason.wessel@windriver.com - - - - - diff --git a/trunk/Documentation/SubmittingPatches b/trunk/Documentation/SubmittingPatches index 1fc4e7144dce..08a1ed1cb5d8 100644 --- a/trunk/Documentation/SubmittingPatches +++ b/trunk/Documentation/SubmittingPatches @@ -328,7 +328,7 @@ now, but you can do this to mark internal company procedures or just point out some special detail about the sign-off. -13) When to use Acked-by: and Cc: +13) When to use Acked-by: The Signed-off-by: tag indicates that the signer was involved in the development of the patch, or that he/she was in the patch's delivery path. @@ -349,59 +349,11 @@ Acked-by: does not necessarily indicate acknowledgement of the entire patch.

The file, when -read, simply produces a set of increasing integer values, one per line. The -sequence will continue until the user loses patience and finds something -better to do. The file is seekable, in that one can do something like the -following: - - dd if=/proc/sequence of=out1 count=1 - dd if=/proc/sequence skip=1 out=out2 count=1 - -Then concatenate the output files out1 and out2 and get the right -result. Yes, it is a thoroughly useless module, but the point is to show -how the mechanism works without getting lost in other details. (Those -wanting to see the full source for this module can find it at -http://lwn.net/Articles/22359/). - - -The iterator interface - -Modules implementing a virtual file with seq_file must implement a simple -iterator object that allows stepping through the data of interest. -Iterators must be able to move to a specific position - like the file they -implement - but the interpretation of that position is up to the iterator -itself. A seq_file implementation that is formatting firewall rules, for -example, could interpret position N as the Nth rule in the chain. -Positioning can thus be done in whatever way makes the most sense for the -generator of the data, which need not be aware of how a position translates -to an offset in the virtual file. The one obvious exception is that a -position of zero should indicate the beginning of the file. - -The /proc/sequence iterator just uses the count of the next number it -will output as its position. - -Four functions must be implemented to make the iterator work. The first, -called start() takes a position as an argument and returns an iterator -which will start reading at that position. For our simple sequence example, -the start() function looks like: - - static void *ct_seq_start(struct seq_file *s, loff_t *pos) - { - loff_t *spos = kmalloc(sizeof(loff_t), GFP_KERNEL); - if (! spos) - return NULL; - *spos = *pos; - return spos; - } - -The entire data structure for this iterator is a single loff_t value -holding the current position. There is no upper bound for the sequence -iterator, but that will not be the case for most other seq_file -implementations; in most cases the start() function should check for a -"past end of file" condition and return NULL if need be. - -For more complicated applications, the private field of the seq_file -structure can be used. There is also a special value which can be returned -by the start() function called SEQ_START_TOKEN; it can be used if you wish -to instruct your show() function (described below) to print a header at the -top of the output. SEQ_START_TOKEN should only be used if the offset is -zero, however. - -The next function to implement is called, amazingly, next(); its job is to -move the iterator forward to the next position in the sequence. The -example module can simply increment the position by one; more useful -modules will do what is needed to step through some data structure. The -next() function returns a new iterator, or NULL if the sequence is -complete. Here's the example version: - - static void *ct_seq_next(struct seq_file *s, void *v, loff_t *pos) - { - loff_t *spos = v; - *pos = ++*spos; - return spos; - } - -The stop() function is called when iteration is complete; its job, of -course, is to clean up. If dynamic memory is allocated for the iterator, -stop() is the place to free it. - - static void ct_seq_stop(struct seq_file *s, void *v) - { - kfree(v); - } - -Finally, the show() function should format the object currently pointed to -by the iterator for output. It should return zero, or an error code if -something goes wrong. The example module's show() function is: - - static int ct_seq_show(struct seq_file *s, void *v) - { - loff_t *spos = v; - seq_printf(s, "%lld\n", (long long)*spos); - return 0; - } - -We will look at seq_printf() in a moment. But first, the definition of the -seq_file iterator is finished by creating a seq_operations structure with -the four functions we have just defined: - - static const struct seq_operations ct_seq_ops = { - .start = ct_seq_start, - .next = ct_seq_next, - .stop = ct_seq_stop, - .show = ct_seq_show - }; - -This structure will be needed to tie our iterator to the /proc file in -a little bit. - -It's worth noting that the iterator value returned by start() and -manipulated by the other functions is considered to be completely opaque by -the seq_file code. It can thus be anything that is useful in stepping -through the data to be output. Counters can be useful, but it could also be -a direct pointer into an array or linked list. Anything goes, as long as -the programmer is aware that things can happen between calls to the -iterator function. However, the seq_file code (by design) will not sleep -between the calls to start() and stop(), so holding a lock during that time -is a reasonable thing to do. The seq_file code will also avoid taking any -other locks while the iterator is active. - - -Formatted output - -The seq_file code manages positioning within the output created by the -iterator and getting it into the user's buffer. But, for that to work, that -output must be passed to the seq_file code. Some utility functions have -been defined which make this task easy. - -Most code will simply use seq_printf(), which works pretty much like -printk(), but which requires the seq_file pointer as an argument. It is -common to ignore the return value from seq_printf(), but a function -producing complicated output may want to check that value and quit if -something non-zero is returned; an error return means that the seq_file -buffer has been filled and further output will be discarded. - -For straight character output, the following functions may be used: - - int seq_putc(struct seq_file *m, char c); - int seq_puts(struct seq_file *m, const char *s); - int seq_escape(struct seq_file *m, const char *s, const char *esc); - -The first two output a single character and a string, just like one would -expect. seq_escape() is like seq_puts(), except that any character in s -which is in the string esc will be represented in octal form in the output. - -There is also a function for printing filenames: - - int seq_path(struct seq_file *m, struct path *path, char *esc); - -Here, path indicates the file of interest, and esc is a set of characters -which should be escaped in the output. - - -Making it all work - -So far, we have a nice set of functions which can produce output within the -seq_file system, but we have not yet turned them into a file that a user -can see. Creating a file within the kernel requires, of course, the -creation of a set of file_operations which implement the operations on that -file. The seq_file interface provides a set of canned operations which do -most of the work. The virtual file author still must implement the open() -method, however, to hook everything up. The open function is often a single -line, as in the example module: - - static int ct_open(struct inode *inode, struct file *file) - { - return seq_open(file, &ct_seq_ops); - } - -Here, the call to seq_open() takes the seq_operations structure we created -before, and gets set up to iterate through the virtual file. - -On a successful open, seq_open() stores the struct seq_file pointer in -file->private_data.

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 + 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 ' 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
