Where to get additional info and help - - -1. About the driver - - The drivers/isdn/hysdn subdir contains a driver for HYPERCOPEs active - PCI isdn cards Champ, Ergo and Metro. To enable support for this cards - enable ISDN support in the kernel config and support for HYSDN cards in - the active cards submenu. The driver may only be compiled and used if - support for loadable modules and the process filesystem have been enabled. - - These cards provide two different interfaces to the kernel. Without the - optional CAPI 2.0 support, they register as ethernet card. IP-routing - to a ISDN-destination is performed on the card itself. All necessary - handlers for various protocols like ppp and others as well as config info - and firmware may be fetched from Hypercopes WWW-Site www.hypercope.de. - - With CAPI 2.0 support enabled, the card can also be used as a CAPI 2.0 - compliant devices with either CAPI 2.0 applications - (check isdn4k-utils) or -using the capidrv module- as a regular - isdn4linux device. This is done via the same mechanism as with the - active AVM cards and in fact uses the same module. - - -2. Loading/Unloading the driver - - The module has no command line parameters and auto detects up to 10 cards - in the id-range 0-9. - If a loaded driver shall be unloaded all open files in the /proc/net/hysdn - subdir need to be closed and all ethernet interfaces allocated by this - driver must be shut down. Otherwise the module counter will avoid a module - unload. - - If you are using the CAPI 2.0-interface, make sure to load/modprobe the - kernelcapi-module first. - - If you plan to use the capidrv-link to isdn4linux, make sure to load - capidrv.o after all modules using this driver (i.e. after hysdn and - any avm-specific modules). - -3. Entries in the /proc filesystem - - When the module has been loaded it adds the directory hysdn in the - /proc/net tree. This directory contains exactly 2 file entries for each - card. One is called cardconfX and the other cardlogX, where X is the - card id number from 0 to 9. - The cards are numbered in the order found in the PCI config data. - -4. The /proc/net/hysdn/cardconfX file - - This file may be read to get by everyone to get info about the cards type, - actual state, available features and used resources. - The first 3 entries (id, bus and slot) are PCI info fields, the following - type field gives the information about the cards type: - - 4 -> Ergo card (server card with 2 b-chans) - 5 -> Metro card (server card with 4 or 8 b-chans) - 6 -> Champ card (client card with 2 b-chans) - - The following 3 fields show the hardware assignments for irq, iobase and the - dual ported memory (dp-mem). - The fields b-chans and fax-chans announce the available card resources of - this types for the user. - The state variable indicates the actual drivers state for this card with the - following assignments. - - 0 -> card has not been booted since driver load - 1 -> card booting is actually in progess - 2 -> card is in an error state due to a previous boot failure - 3 -> card is booted and active - - And the last field (device) shows the name of the ethernet device assigned - to this card. Up to the first successful boot this field only shows a - - to tell that no net device has been allocated up to now. Once a net device - has been allocated it remains assigned to this card, even if a card is - rebooted and an boot error occurs. - - Writing to the cardconfX file boots the card or transfers config lines to - the cards firmware. The type of data is automatically detected when the - first data is written. Only root has write access to this file. - The firmware boot files are normally called hyclient.pof for client cards - and hyserver.pof for server cards. - After successfully writing the boot file, complete config files or single - config lines may be copied to this file. - If an error occurs the return value given to the writing process has the - following additional codes (decimal): - - 1000 Another process is currently bootng the card - 1001 Invalid firmware header - 1002 Boards dual-port RAM test failed - 1003 Internal firmware handler error - 1004 Boot image size invalid - 1005 First boot stage (bootstrap loader) failed - 1006 Second boot stage failure - 1007 Timeout waiting for card ready during boot - 1008 Operation only allowed in booted state - 1009 Config line too long - 1010 Invalid channel number - 1011 Timeout sending config data - - Additional info about error reasons may be fetched from the log output. - -5. The /proc/net/hysdn/cardlogX file - - The cardlogX file entry may be opened multiple for reading by everyone to - get the cards and drivers log data. Card messages always start with the - keyword LOG. All other lines are output from the driver. - The driver log data may be redirected to the syslog by selecting the - appropriate bitmask. The cards log messages will always be send to this - interface but never to the syslog. - - A root user may write a decimal or hex (with 0x) value t this file to select - desired output options. As mentioned above the cards log dat is always - written to the cardlog file independent of the following options only used - to check and debug the driver itself: - - For example: - echo "0x34560078" > /proc/net/hysdn/cardlog0 - to output the hex log mask 34560078 for card 0. - - The written value is regarded as an unsigned 32-Bit value, bit ored for - desired output. The following bits are already assigned: - - 0x80000000 All driver log data is alternatively via syslog - 0x00000001 Log memory allocation errors - 0x00000010 Firmware load start and close are logged - 0x00000020 Log firmware record parser - 0x00000040 Log every firmware write actions - 0x00000080 Log all card related boot messages - 0x00000100 Output all config data sent for debugging purposes - 0x00000200 Only non comment config lines are shown wth channel - 0x00000400 Additional conf log output - 0x00001000 Log the asynchronous scheduler actions (config and log) - 0x00100000 Log all open and close actions to /proc/net/hysdn/card files - 0x00200000 Log all actions from /proc file entries - 0x00010000 Log network interface init and deinit - -6.
