46 The drivers/isdn/hysdn subdir contains a driver for HYPERCOPEs active
47 PCI isdn cards Champ, Ergo and Metro. To enable support for this cards
48 enable ISDN support in the kernel config and support for HYSDN cards in
49 the active cards submenu. The driver may only be compiled and used if
50 support for loadable modules and the process filesystem have been enabled.
52 These cards provide two different interfaces to the kernel. Without the
53 optional CAPI 2.0 support, they register as ethernet card. IP-routing
54 to a ISDN-destination is performed on the card itself. All necessary
55 handlers for various protocols like ppp and others as well as config info
56 and firmware may be fetched from Hypercopes WWW-Site www.hypercope.de.
58 With CAPI 2.0 support enabled, the card can also be used as a CAPI 2.0
59 compliant devices with either CAPI 2.0 applications
60 (check isdn4k-utils) or -using the capidrv module- as a regular
61 isdn4linux device. This is done via the same mechanism as with the
62 active AVM cards and in fact uses the same module.
65 2. Loading/Unloading the driver
66 ===============================
68 The module has no command line parameters and auto detects up to 10 cards
70 If a loaded driver shall be unloaded all open files in the /proc/net/hysdn
71 subdir need to be closed and all ethernet interfaces allocated by this
72 driver must be shut down. Otherwise the module counter will avoid a module
75 If you are using the CAPI 2.0-interface, make sure to load/modprobe the
76 kernelcapi-module first.
78 If you plan to use the capidrv-link to isdn4linux, make sure to load
79 capidrv.o after all modules using this driver (i.e. after hysdn and
80 any avm-specific modules).
82 3. Entries in the /proc filesystem
83 ==================================
85 When the module has been loaded it adds the directory hysdn in the
86 /proc/net tree. This directory contains exactly 2 file entries for each
87 card. One is called cardconfX and the other cardlogX, where X is the
88 card id number from 0 to 9.
89 The cards are numbered in the order found in the PCI config data.
91 4. The /proc/net/hysdn/cardconfX file
92 =====================================
94 This file may be read to get by everyone to get info about the cards type,
95 actual state, available features and used resources.
96 The first 3 entries (id, bus and slot) are PCI info fields, the following
97 type field gives the information about the cards type:
99 - 4 -> Ergo card (server card with 2 b-chans)
100 - 5 -> Metro card (server card with 4 or 8 b-chans)
101 - 6 -> Champ card (client card with 2 b-chans)
103 The following 3 fields show the hardware assignments for irq, iobase and the
104 dual ported memory (dp-mem).
106 The fields b-chans and fax-chans announce the available card resources of
107 this types for the user.
109 The state variable indicates the actual drivers state for this card with the
110 following assignments.
112 - 0 -> card has not been booted since driver load
113 - 1 -> card booting is actually in progess
114 - 2 -> card is in an error state due to a previous boot failure
115 - 3 -> card is booted and active
117 And the last field (device) shows the name of the ethernet device assigned
118 to this card. Up to the first successful boot this field only shows a -
119 to tell that no net device has been allocated up to now. Once a net device
120 has been allocated it remains assigned to this card, even if a card is
121 rebooted and an boot error occurs.
123 Writing to the cardconfX file boots the card or transfers config lines to
124 the cards firmware. The type of data is automatically detected when the
125 first data is written. Only root has write access to this file.
126 The firmware boot files are normally called hyclient.pof for client cards
127 and hyserver.pof for server cards.
128 After successfully writing the boot file, complete config files or single
129 config lines may be copied to this file.
130 If an error occurs the return value given to the writing process has the
131 following additional codes (decimal):
133 ==== ============================================
134 1000 Another process is currently bootng the card
135 1001 Invalid firmware header
136 1002 Boards dual-port RAM test failed
137 1003 Internal firmware handler error
138 1004 Boot image size invalid
139 1005 First boot stage (bootstrap loader) failed
140 1006 Second boot stage failure
141 1007 Timeout waiting for card ready during boot
142 1008 Operation only allowed in booted state
143 1009 Config line too long
144 1010 Invalid channel number
145 1011 Timeout sending config data
146 ==== ============================================
148 Additional info about error reasons may be fetched from the log output.
150 5. The /proc/net/hysdn/cardlogX file
151 ====================================
153 The cardlogX file entry may be opened multiple for reading by everyone to
154 get the cards and drivers log data. Card messages always start with the
155 keyword LOG. All other lines are output from the driver.
156 The driver log data may be redirected to the syslog by selecting the
157 appropriate bitmask. The cards log messages will always be send to this
158 interface but never to the syslog.
160 A root user may write a decimal or hex (with 0x) value t this file to select
161 desired output options. As mentioned above the cards log dat is always
162 written to the cardlog file independent of the following options only used
163 to check and debug the driver itself:
167 echo "0x34560078" > /proc/net/hysdn/cardlog0
169 to output the hex log mask 34560078 for card 0.
171 The written value is regarded as an unsigned 32-Bit value, bit ored for
172 desired output. The following bits are already assigned:
174 ========== ============================================================
175 0x80000000 All driver log data is alternatively via syslog
176 0x00000001 Log memory allocation errors
177 0x00000010 Firmware load start and close are logged
178 0x00000020 Log firmware record parser
179 0x00000040 Log every firmware write actions
180 0x00000080 Log all card related boot messages
181 0x00000100 Output all config data sent for debugging purposes
182 0x00000200 Only non comment config lines are shown wth channel
183 0x00000400 Additional conf log output
184 0x00001000 Log the asynchronous scheduler actions (config and log)
185 0x00100000 Log all open and close actions to /proc/net/hysdn/card files
186 0x00200000 Log all actions from /proc file entries
187 0x00010000 Log network interface init and deinit
