Where to get additional info and help 39 40 411. About the driver 42 43 The drivers/isdn/hysdn subdir contains a driver for HYPERCOPEs active 44 PCI isdn cards Champ, Ergo and Metro. To enable support for this cards 45 enable ISDN support in the kernel config and support for HYSDN cards in 46 the active cards submenu. The driver may only be compiled and used if 47 support for loadable modules and the process filesystem have been enabled. 48 49 These cards provide two different interfaces to the kernel. Without the 50 optional CAPI 2.0 support, they register as ethernet card. IP-routing 51 to a ISDN-destination is performed on the card itself. All necessary 52 handlers for various protocols like ppp and others as well as config info 53 and firmware may be fetched from Hypercopes WWW-Site www.hypercope.de. 54 55 With CAPI 2.0 support enabled, the card can also be used as a CAPI 2.0 56 compliant devices with either CAPI 2.0 applications 57 (check isdn4k-utils) or -using the capidrv module- as a regular 58 isdn4linux device. This is done via the same mechanism as with the 59 active AVM cards and in fact uses the same module. 60 61 622. Loading/Unloading the driver 63 64 The module has no command line parameters and auto detects up to 10 cards 65 in the id-range 0-9. 66 If a loaded driver shall be unloaded all open files in the /proc/net/hysdn 67 subdir need to be closed and all ethernet interfaces allocated by this 68 driver must be shut down. Otherwise the module counter will avoid a module 69 unload. 70 71 If you are using the CAPI 2.0-interface, make sure to load/modprobe the 72 kernelcapi-module first. 73 74 If you plan to use the capidrv-link to isdn4linux, make sure to load 75 capidrv.o after all modules using this driver (i.e. after hysdn and 76 any avm-specific modules). 77 783. Entries in the /proc filesystem 79 80 When the module has been loaded it adds the directory hysdn in the 81 /proc/net tree. This directory contains exactly 2 file entries for each 82 card. One is called cardconfX and the other cardlogX, where X is the 83 card id number from 0 to 9. 84 The cards are numbered in the order found in the PCI config data. 85 864. The /proc/net/hysdn/cardconfX file 87 88 This file may be read to get by everyone to get info about the cards type, 89 actual state, available features and used resources. 90 The first 3 entries (id, bus and slot) are PCI info fields, the following 91 type field gives the information about the cards type: 92 93 4 -> Ergo card (server card with 2 b-chans) 94 5 -> Metro card (server card with 4 or 8 b-chans) 95 6 -> Champ card (client card with 2 b-chans) 96 97 The following 3 fields show the hardware assignments for irq, iobase and the 98 dual ported memory (dp-mem). 99 The fields b-chans and fax-chans announce the available card resources of 100 this types for the user. 101 The state variable indicates the actual drivers state for this card with the 102 following assignments. 103 104 0 -> card has not been booted since driver load 105 1 -> card booting is actually in progess 106 2 -> card is in an error state due to a previous boot failure 107 3 -> card is booted and active 108 109 And the last field (device) shows the name of the ethernet device assigned 110 to this card. Up to the first successful boot this field only shows a - 111 to tell that no net device has been allocated up to now. Once a net device 112 has been allocated it remains assigned to this card, even if a card is 113 rebooted and an boot error occurs. 114 115 Writing to the cardconfX file boots the card or transfers config lines to 116 the cards firmware. The type of data is automatically detected when the 117 first data is written. Only root has write access to this file. 118 The firmware boot files are normally called hyclient.pof for client cards 119 and hyserver.pof for server cards. 120 After successfully writing the boot file, complete config files or single 121 config lines may be copied to this file. 122 If an error occurs the return value given to the writing process has the 123 following additional codes (decimal): 124 125 1000 Another process is currently bootng the card 126 1001 Invalid firmware header 127 1002 Boards dual-port RAM test failed 128 1003 Internal firmware handler error 129 1004 Boot image size invalid 130 1005 First boot stage (bootstrap loader) failed 131 1006 Second boot stage failure 132 1007 Timeout waiting for card ready during boot 133 1008 Operation only allowed in booted state 134 1009 Config line too long 135 1010 Invalid channel number 136 1011 Timeout sending config data 137 138 Additional info about error reasons may be fetched from the log output. 139 1405. The /proc/net/hysdn/cardlogX file 141 142 The cardlogX file entry may be opened multiple for reading by everyone to 143 get the cards and drivers log data. Card messages always start with the 144 keyword LOG. All other lines are output from the driver. 145 The driver log data may be redirected to the syslog by selecting the 146 appropriate bitmask. The cards log messages will always be send to this 147 interface but never to the syslog. 148 149 A root user may write a decimal or hex (with 0x) value t this file to select 150 desired output options. As mentioned above the cards log dat is always 151 written to the cardlog file independent of the following options only used 152 to check and debug the driver itself: 153 154 For example: 155 echo "0x34560078" > /proc/net/hysdn/cardlog0 156 to output the hex log mask 34560078 for card 0. 157 158 The written value is regarded as an unsigned 32-Bit value, bit ored for 159 desired output. The following bits are already assigned: 160 161 0x80000000 All driver log data is alternatively via syslog 162 0x00000001 Log memory allocation errors 163 0x00000010 Firmware load start and close are logged 164 0x00000020 Log firmware record parser 165 0x00000040 Log every firmware write actions 166 0x00000080 Log all card related boot messages 167 0x00000100 Output all config data sent for debugging purposes 168 0x00000200 Only non comment config lines are shown wth channel 169 0x00000400 Additional conf log output 170 0x00001000 Log the asynchronous scheduler actions (config and log) 171 0x00100000 Log all open and close actions to /proc/net/hysdn/card files 172 0x00200000 Log all actions from /proc file entries 173 0x00010000 Log network interface init and deinit 174 1756.
