It no longer inverts * outputs on those cards by default as it didn't make much sense. If * you require the outputs to be inverted on those cards for legacy * reasons, set the module parameter "legacy_invert_outputs=true" when * loading the module, or set "ni_65xx.legacy_invert_outputs=true" on * the kernel command line if the driver is built in to the kernel. */ /* * Manuals (available from ftp://ftp.natinst.com/support/manuals) * * 370106b.pdf 6514 Register Level Programmer Manual */ #include <linux/module.h> #include <linux/interrupt.h> #include <linux/comedi/comedi_pci.h> /* * PCI BAR1 Register Map */ /* Non-recurring Registers (8-bit except where noted) */ #define NI_65XX_ID_REG … #define NI_65XX_CLR_REG … #define NI_65XX_CLR_WDOG_INT … #define NI_65XX_CLR_WDOG_PING … #define NI_65XX_CLR_WDOG_EXP … #define NI_65XX_CLR_EDGE_INT … #define NI_65XX_CLR_OVERFLOW_INT … #define NI_65XX_STATUS_REG … #define NI_65XX_STATUS_WDOG_INT … #define NI_65XX_STATUS_FALL_EDGE … #define NI_65XX_STATUS_RISE_EDGE … #define NI_65XX_STATUS_INT … #define NI_65XX_STATUS_OVERFLOW_INT … #define NI_65XX_STATUS_EDGE_INT … #define NI_65XX_CTRL_REG … #define NI_65XX_CTRL_WDOG_ENA … #define NI_65XX_CTRL_FALL_EDGE_ENA … #define NI_65XX_CTRL_RISE_EDGE_ENA … #define NI_65XX_CTRL_INT_ENA … #define NI_65XX_CTRL_OVERFLOW_ENA … #define NI_65XX_CTRL_EDGE_ENA … #define NI_65XX_REV_REG … #define NI_65XX_FILTER_REG … #define NI_65XX_RTSI_ROUTE_REG … #define NI_65XX_RTSI_EDGE_REG … #define NI_65XX_RTSI_WDOG_REG … #define NI_65XX_RTSI_TRIG_REG … #define NI_65XX_AUTO_CLK_SEL_REG … #define NI_65XX_AUTO_CLK_SEL_STATUS … #define NI_65XX_AUTO_CLK_SEL_DISABLE … #define NI_65XX_WDOG_CTRL_REG … #define NI_65XX_WDOG_CTRL_ENA … #define NI_65XX_RTSI_CFG_REG … #define NI_65XX_RTSI_CFG_RISE_SENSE … #define NI_65XX_RTSI_CFG_FALL_SENSE … #define NI_65XX_RTSI_CFG_SYNC_DETECT … #define NI_65XX_WDOG_STATUS_REG … #define NI_65XX_WDOG_STATUS_EXP … #define NI_65XX_WDOG_INTERVAL_REG … /* Recurring port registers (8-bit) */ #define NI_65XX_PORT(x) … #define NI_65XX_IO_DATA_REG(x) … #define NI_65XX_IO_SEL_REG(x) … #define NI_65XX_IO_SEL_OUTPUT … #define NI_65XX_IO_SEL_INPUT … #define NI_65XX_RISE_EDGE_ENA_REG(x) … #define NI_65XX_FALL_EDGE_ENA_REG(x) … #define NI_65XX_FILTER_ENA(x) … #define NI_65XX_WDOG_HIZ_REG(x) … #define NI_65XX_WDOG_ENA(x) … #define NI_65XX_WDOG_HI_LO_REG(x) … #define NI_65XX_RTSI_ENA(x) … #define NI_65XX_PORT_TO_CHAN(x) … #define NI_65XX_CHAN_TO_PORT(x) … #define NI_65XX_CHAN_TO_MASK(x) … enum ni_65xx_boardid { … }; struct ni_65xx_board { … }; static const struct ni_65xx_board ni_65xx_boards[] = …; static bool ni_65xx_legacy_invert_outputs; module_param_named(legacy_invert_outputs, ni_65xx_legacy_invert_outputs, bool, 0444); MODULE_PARM_DESC(…) …; static unsigned int ni_65xx_num_ports(struct comedi_device *dev) { … } static void ni_65xx_disable_input_filters(struct comedi_device *dev) { … } /* updates edge detection for base_chan to base_chan+31 */ static void ni_65xx_update_edge_detection(struct comedi_device *dev, unsigned int base_chan, unsigned int rising, unsigned int falling) { … } static void ni_65xx_disable_edge_detection(struct comedi_device *dev) { … } static int ni_65xx_dio_insn_config(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static int ni_65xx_dio_insn_bits(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static irqreturn_t ni_65xx_interrupt(int irq, void *d) { … } static int ni_65xx_intr_cmdtest(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_cmd *cmd) { … } static int ni_65xx_intr_cmd(struct comedi_device *dev, struct comedi_subdevice *s) { … } static int ni_65xx_intr_cancel(struct comedi_device *dev, struct comedi_subdevice *s) { … } static int ni_65xx_intr_insn_bits(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } static int ni_65xx_intr_insn_config(struct comedi_device *dev, struct comedi_subdevice *s, struct comedi_insn *insn, unsigned int *data) { … } /* ripped from mite.h and mite_setup2() to avoid mite dependency */ #define MITE_IODWBSR … #define WENAB … static int ni_65xx_mite_init(struct pci_dev *pcidev) { … } static int ni_65xx_auto_attach(struct comedi_device *dev, unsigned long context) { … } static void ni_65xx_detach(struct comedi_device *dev) { … } static struct comedi_driver ni_65xx_driver = …; static int ni_65xx_pci_probe(struct pci_dev *dev, const struct pci_device_id *id) { … } static const struct pci_device_id ni_65xx_pci_table[] = …; MODULE_DEVICE_TABLE(pci, ni_65xx_pci_table); static struct pci_driver ni_65xx_pci_driver = …; module_comedi_pci_driver(…); MODULE_AUTHOR(…) …; MODULE_DESCRIPTION(…) …; MODULE_LICENSE(…) …;
