(otherwise auto) * or Bit 12 = 0x01000 = Force PCM bus into master mode. (otherwise auto) * Bit 13 = spare * Bit 14 = 0x04000 = Use external ram (128K) * Bit 15 = 0x08000 = Use external ram (512K) * Bit 16 = 0x10000 = Use 64 timeslots instead of 32 * or Bit 17 = 0x20000 = Use 128 timeslots instead of anything else * Bit 18 = spare * Bit 19 = 0x80000 = Send the Watchdog a Signal (Dual E1 with Watchdog) * (all other bits are reserved and shall be 0) * example: 0x20204 one HFC-4S with dtmf detection and 128 timeslots on PCM * bus (PCM master) * * port: (optional or required for all ports on all installed cards) * HFC-4S/HFC-8S only bits: * Bit 0 = 0x001 = Use master clock for this S/T interface * (only once per chip). * Bit 1 = 0x002 = transmitter line setup (non capacitive mode) * Don't use this unless you know what you are doing! * Bit 2 = 0x004 = Disable E-channel. (No E-channel processing) * example: 0x0001,0x0000,0x0000,0x0000 one HFC-4S with master clock * received from port 1 * * HFC-E1 only bits: * Bit 0 = 0x0001 = interface: 0=copper, 1=optical * Bit 1 = 0x0002 = reserved (later for 32 B-channels transparent mode) * Bit 2 = 0x0004 = Report LOS * Bit 3 = 0x0008 = Report AIS * Bit 4 = 0x0010 = Report SLIP * Bit 5 = 0x0020 = Report RDI * Bit 8 = 0x0100 = Turn off CRC-4 Multiframe Mode, use double frame * mode instead. * Bit 9 = 0x0200 = Force get clock from interface, even in NT mode. * or Bit 10 = 0x0400 = Force put clock to interface, even in TE mode. * Bit 11 = 0x0800 = Use direct RX clock for PCM sync rather than PLL. * (E1 only) * Bit 12-13 = 0xX000 = elastic jitter buffer (1-3), Set both bits to 0 * for default. * (all other bits are reserved and shall be 0) * * debug: * NOTE: only one debug value must be given for all cards * enable debugging (see hfc_multi.h for debug options) * * poll: * NOTE: only one poll value must be given for all cards * Give the number of samples for each fifo process. * By default 128 is used. Decrease to reduce delay, increase to * reduce cpu load. If unsure, don't mess with it! * Valid is 8, 16, 32, 64, 128, 256. * * pcm: * NOTE: only one pcm value must be given for every card. * The PCM bus id tells the mISDNdsp module about the connected PCM bus. * By default (0), the PCM bus id is 100 for the card that is PCM master. * If multiple cards are PCM master (because they are not interconnected), * each card with PCM master will have increasing PCM id. * All PCM buses with the same ID are expected to be connected and have * common time slots slots. * Only one chip of the PCM bus must be master, the others slave. * -1 means no support of PCM bus not even. * Omit this value, if all cards are interconnected or none is connected. * If unsure, don't give this parameter. * * dmask and bmask: * NOTE: One dmask value must be given for every HFC-E1 card. * If omitted, the E1 card has D-channel on time slot 16, which is default. * dmask is a 32 bit mask. The bit must be set for an alternate time slot. * If multiple bits are set, multiple virtual card fragments are created. * For each bit set, a bmask value must be given. Each bit on the bmask * value stands for a B-channel. The bmask may not overlap with dmask or * with other bmask values for that card. * Example: dmask=0x00020002 bmask=0x0000fffc,0xfffc0000 * This will create one fragment with D-channel on slot 1 with * B-channels on slots 2..15, and a second fragment with D-channel * on slot 17 with B-channels on slot 18..31. Slot 16 is unused. * If bit 0 is set (dmask=0x00000001) the D-channel is on slot 0 and will * not function. * Example: dmask=0x00000001 bmask=0xfffffffe * This will create a port with all 31 usable timeslots as * B-channels. * If no bits are set on bmask, no B-channel is created for that fragment. * Example: dmask=0xfffffffe bmask=0,0,0,0.... (31 0-values for bmask) * This will create 31 ports with one D-channel only. * If you don't know how to use it, you don't need it! * * iomode: * NOTE: only one mode value must be given for every card. * -> See hfc_multi.h for HFC_IO_MODE_* values * By default, the IO mode is pci memory IO (MEMIO). * Some cards require specific IO mode, so it cannot be changed. * It may be useful to set IO mode to register io (REGIO) to solve * PCI bridge problems. * If unsure, don't give this parameter. * * clockdelay_nt: * NOTE: only one clockdelay_nt value must be given once for all cards. * Give the value of the clock control register (A_ST_CLK_DLY) * of the S/T interfaces in NT mode. * This register is needed for the TBR3 certification, so don't change it. * * clockdelay_te: * NOTE: only one clockdelay_te value must be given once * Give the value of the clock control register (A_ST_CLK_DLY) * of the S/T interfaces in TE mode. * This register is needed for the TBR3 certification, so don't change it. * * clock: * NOTE: only one clock value must be given once * Selects interface with clock source for mISDN and applications. * Set to card number starting with 1. Set to -1 to disable. * By default, the first card is used as clock source. * * hwid: * NOTE: only one hwid value must be given once * Enable special embedded devices with XHFC controllers. */ /* * debug register access (never use this, it will flood your system log) * #define HFC_REGISTER_DEBUG */ #define HFC_MULTI_VERSION "2.03" #include <linux/interrupt.h> #include <linux/module.h> #include <linux/slab.h> #include <linux/pci.h> #include <linux/delay.h> #include <linux/mISDNhw.h> #include <linux/mISDNdsp.h> /* #define IRQCOUNT_DEBUG #define IRQ_DEBUG */ #include "hfc_multi.h" #ifdef ECHOPREP #include "gaintab.h" #endif #define MAX_CARDS 8 #define MAX_PORTS (8 * MAX_CARDS) #define MAX_FRAGS (32 * MAX_CARDS) static LIST_HEAD(HFClist);
