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 +*** + + + +***End of Readme File*** diff --git a/Documentation/video4linux/cx2341x/fw-encoder-api.txt b/Documentation/video4linux/cx2341x/fw-encoder-api.txt index 5dd3109a8b3f..5a27af2ee1c6 100644 --- a/Documentation/video4linux/cx2341x/fw-encoder-api.txt +++ b/Documentation/video4linux/cx2341x/fw-encoder-api.txt @@ -407,8 +407,10 @@ Description u32 length; // Length of this frame u32 offset_low; // Offset in the file of the u32 offset_high; // start of this frame - u32 mask1; // Bits 0-1 are the type mask: + u32 mask1; // Bits 0-2 are the type mask: // 1=I, 2=P, 4=B + // 0=End of Program Index, other fields + // are invalid. u32 pts; // The PTS of the frame u32 mask2; // Bit 0 is bit 32 of the pts. }; |
