(otherwhise auto) 43 * or Bit 12 = 0x01000 = Force PCM bus into master mode. (otherwhise auto) 44 * Bit 13 = spare 45 * Bit 14 = 0x04000 = Use external ram (128K) 46 * Bit 15 = 0x08000 = Use external ram (512K) 47 * Bit 16 = 0x10000 = Use 64 timeslots instead of 32 48 * or Bit 17 = 0x20000 = Use 128 timeslots instead of anything else 49 * Bit 18 = spare 50 * Bit 19 = 0x80000 = Send the Watchdog a Signal (Dual E1 with Watchdog) 51 * (all other bits are reserved and shall be 0) 52 * example: 0x20204 one HFC-4S with dtmf detection and 128 timeslots on PCM 53 * bus (PCM master) 54 * 55 * port: (optional or required for all ports on all installed cards) 56 * HFC-4S/HFC-8S only bits: 57 * Bit 0 = 0x001 = Use master clock for this S/T interface 58 * (ony once per chip). 59 * Bit 1 = 0x002 = transmitter line setup (non capacitive mode) 60 * Don't use this unless you know what you are doing! 61 * Bit 2 = 0x004 = Disable E-channel. (No E-channel processing) 62 * example: 0x0001,0x0000,0x0000,0x0000 one HFC-4S with master clock 63 * received from port 1 64 * 65 * HFC-E1 only bits: 66 * Bit 0 = 0x0001 = interface: 0=copper, 1=optical 67 * Bit 1 = 0x0002 = reserved (later for 32 B-channels transparent mode) 68 * Bit 2 = 0x0004 = Report LOS 69 * Bit 3 = 0x0008 = Report AIS 70 * Bit 4 = 0x0010 = Report SLIP 71 * Bit 5 = 0x0020 = Report RDI 72 * Bit 8 = 0x0100 = Turn off CRC-4 Multiframe Mode, use double frame 73 * mode instead. 74 * Bit 9 = 0x0200 = Force get clock from interface, even in NT mode. 75 * or Bit 10 = 0x0400 = Force put clock to interface, even in TE mode. 76 * Bit 11 = 0x0800 = Use direct RX clock for PCM sync rather than PLL. 77 * (E1 only) 78 * Bit 12-13 = 0xX000 = elastic jitter buffer (1-3), Set both bits to 0 79 * for default. 80 * (all other bits are reserved and shall be 0) 81 * 82 * debug: 83 * NOTE: only one debug value must be given for all cards 84 * enable debugging (see hfc_multi.h for debug options) 85 * 86 * poll: 87 * NOTE: only one poll value must be given for all cards 88 * Give the number of samples for each fifo process. 89 * By default 128 is used. Decrease to reduce delay, increase to 90 * reduce cpu load. If unsure, don't mess with it! 91 * Valid is 8, 16, 32, 64, 128, 256. 92 * 93 * pcm: 94 * NOTE: only one pcm value must be given for every card. 95 * The PCM bus id tells the mISDNdsp module about the connected PCM bus. 96 * By default (0), the PCM bus id is 100 for the card that is PCM master. 97 * If multiple cards are PCM master (because they are not interconnected), 98 * each card with PCM master will have increasing PCM id. 99 * All PCM busses with the same ID are expected to be connected and have 100 * common time slots slots. 101 * Only one chip of the PCM bus must be master, the others slave. 102 * -1 means no support of PCM bus not even. 103 * Omit this value, if all cards are interconnected or none is connected. 104 * If unsure, don't give this parameter. 105 * 106 * dmask and bmask: 107 * NOTE: One dmask value must be given for every HFC-E1 card. 108 * If omitted, the E1 card has D-channel on time slot 16, which is default. 109 * dmask is a 32 bit mask. The bit must be set for an alternate time slot. 110 * If multiple bits are set, multiple virtual card fragments are created. 111 * For each bit set, a bmask value must be given. Each bit on the bmask 112 * value stands for a B-channel. The bmask may not overlap with dmask or 113 * with other bmask values for that card. 114 * Example: dmask=0x00020002 bmask=0x0000fffc,0xfffc0000 115 * This will create one fragment with D-channel on slot 1 with 116 * B-channels on slots 2..15, and a second fragment with D-channel 117 * on slot 17 with B-channels on slot 18..31. Slot 16 is unused. 118 * If bit 0 is set (dmask=0x00000001) the D-channel is on slot 0 and will 119 * not function. 120 * Example: dmask=0x00000001 bmask=0xfffffffe 121 * This will create a port with all 31 usable timeslots as 122 * B-channels. 123 * If no bits are set on bmask, no B-channel is created for that fragment. 124 * Example: dmask=0xfffffffe bmask=0,0,0,0.... (31 0-values for bmask) 125 * This will create 31 ports with one D-channel only. 126 * If you don't know how to use it, you don't need it! 127 * 128 * iomode: 129 * NOTE: only one mode value must be given for every card. 130 * -> See hfc_multi.h for HFC_IO_MODE_* values 131 * By default, the IO mode is pci memory IO (MEMIO). 132 * Some cards require specific IO mode, so it cannot be changed. 133 * It may be useful to set IO mode to register io (REGIO) to solve 134 * PCI bridge problems. 135 * If unsure, don't give this parameter. 136 * 137 * clockdelay_nt: 138 * NOTE: only one clockdelay_nt value must be given once for all cards. 139 * Give the value of the clock control register (A_ST_CLK_DLY) 140 * of the S/T interfaces in NT mode. 141 * This register is needed for the TBR3 certification, so don't change it. 142 * 143 * clockdelay_te: 144 * NOTE: only one clockdelay_te value must be given once 145 * Give the value of the clock control register (A_ST_CLK_DLY) 146 * of the S/T interfaces in TE mode. 147 * This register is needed for the TBR3 certification, so don't change it. 148 * 149 * clock: 150 * NOTE: only one clock value must be given once 151 * Selects interface with clock source for mISDN and applications. 152 * Set to card number starting with 1. Set to -1 to disable. 153 * By default, the first card is used as clock source. 154 * 155 * hwid: 156 * NOTE: only one hwid value must be given once 157 * Enable special embedded devices with XHFC controllers. 158 */ 159 160 /* 161 * debug register access (never use this, it will flood your system log) 162 * #define HFC_REGISTER_DEBUG 163 */ 164 165 #define HFC_MULTI_VERSION "2.03" 166 167 #include <linux/interrupt.h> 168 #include <linux/module.h> 169 #include <linux/slab.h> 170 #include <linux/pci.h> 171 #include <linux/delay.h> 172 #include <linux/mISDNhw.h> 173 #include <linux/mISDNdsp.h> 174 175 /* 176 #define IRQCOUNT_DEBUG 177 #define IRQ_DEBUG 178 */ 179 180 #include "hfc_multi.h" 181 #ifdef ECHOPREP 182 #include "gaintab.h" 183 #endif 184 185 #define MAX_CARDS 8 186 #define MAX_PORTS (8 * MAX_CARDS) 187 #define MAX_FRAGS (32 * MAX_CARDS) 188 189 static LIST_HEAD(HFClist);
