It - also has a tone generator. Output data for LPC are written to the - LPC port, and output data for the other modes are written to the - TTS port. - - Two kinds of data can be read from the DoubleTalk: status - information (in response to the "\001?" interrogation command) is - read from the TTS port, and index markers (which mark the progress - of the speech) are read from the LPC port. Not all models of the - DoubleTalk PC implement index markers. Both the TTS and LPC ports - can also display status flags. - - The DoubleTalk PC generates no interrupts. - - These characteristics are mapped into the Unix stream I/O model as - follows: - - "write" sends bytes to the TTS port. It is the responsibility of - the user program to switch modes among TTS, PCM/ADPCM, and CVSD. - This driver was written for use with the text-to-speech - synthesizer. If LPC output is needed some day, other minor device - numbers can be used to select among output modes. - - "read" gets index markers from the LPC port. If the device does - not implement index markers, the read will fail with error EINVAL. - - Status information is available using the DTLK_INTERROGATE ioctl. - - */ - -#include - -#define KERNEL -#include -#include -#include -#include /* for -EBUSY */ -#include /* for request_region */ -#include /* for loops_per_jiffy */ -#include -#include -#include /* for inb_p, outb_p, inb, outb, etc. */ -#include /* for get_user, etc. */ -#include /* for wait_queue */ -#include /* for __init, module_{init,exit} */ -#include /* for EPOLLIN, etc. */ -#include /* local header file for DoubleTalk values */ - -#ifdef TRACING -#define TRACE_TEXT(str) printk(str); -#define TRACE_RET printk(")") -#else /* !TRACING */ -#define TRACE_TEXT(str) ((void) 0) -#define TRACE_RET ((void) 0) -#endif /* TRACING */ - -static DEFINE_MUTEX(dtlk_mutex); -static void dtlk_timer_tick(struct timer_list *unused); - -static int dtlk_major; -static int dtlk_port_lpc; -static int dtlk_port_tts; -static int dtlk_busy; -static int dtlk_has_indexing; -static unsigned int dtlk_portlist[] = -{0x25e, 0x29e, 0x2de, 0x31e, 0x35e, 0x39e, 0}; -static wait_queue_head_t dtlk_process_list; -static DEFINE_TIMER(dtlk_timer, dtlk_timer_tick); - -/* prototypes for file_operations struct */ -static ssize_t dtlk_read(struct file *, char __user *, - size_t nbytes, loff_t * ppos); -static ssize_t dtlk_write(struct file *, const char __user *, - size_t nbytes, loff_t * ppos); -static __poll_t dtlk_poll(struct file *, poll_table *); -static int dtlk_open(struct inode *, struct file *); -static int dtlk_release(struct inode *, struct file *); -static long dtlk_ioctl(struct file *file, - unsigned int cmd, unsigned long arg); - -static const struct file_operations dtlk_fops = -{ - .owner = THIS_MODULE, - .read = dtlk_read, - .write = dtlk_write, - .poll = dtlk_poll, - .unlocked_ioctl = dtlk_ioctl, - .open = dtlk_open, - .release = dtlk_release, -}; - -/* local prototypes */ -static int dtlk_dev_probe(void); -static struct dtlk_settings *dtlk_interrogate(void); -static int dtlk_readable(void); -static char dtlk_read_lpc(void); -static char dtlk_read_tts(void); -static int dtlk_writeable(void); -static char dtlk_write_bytes(const char *buf, int n); -static char dtlk_write_tts(char); -/* - static void dtlk_handle_error(char, char, unsigned int); - */ - -static ssize_t dtlk_read(struct file *file, char __user *buf, - size_t count, loff_t * ppos) -{ - unsigned int minor = iminor(file_inode(file)); - char ch; - int i = 0, retries; - - TRACE_TEXT("(dtlk_read"); - /* printk("DoubleTalk PC - dtlk_read()\n"); */ - - if (minor != DTLK_MINOR || !dtlk_has_indexing) - return -EINVAL; - - for (retries = 0; retries < loops_per_jiffy; retries++) { - while (i < count && dtlk_readable()) { - ch = dtlk_read_lpc(); - /* printk("dtlk_read() reads 0x%02x\n", ch); */ - if (put_user(ch, buf++)) - return -EFAULT; - i++; - } - if (i) - return i; - if (file->f_flags & O_NONBLOCK) - break; - msleep_interruptible(100); - } - if (retries == loops_per_jiffy) - printk(KERN_ERR "dtlk_read times out\n"); - TRACE_RET; - return -EAGAIN; -} - -static ssize_t dtlk_write(struct file *file, const char __user *buf, - size_t count, loff_t * ppos) -{ - int i = 0, retries = 0, ch; - - TRACE_TEXT("(dtlk_write"); -#ifdef TRACING - printk(" \""); - { - int i, ch; - for (i = 0; i < count; i++) { - if (get_user(ch, buf + i)) - return -EFAULT; - if (' ' <= ch && ch <= '~') - printk("%c", ch); - else - printk("\\%03o", ch); - } - printk("\""); - } -#endif - - if (iminor(file_inode(file)) != DTLK_MINOR) - return -EINVAL; - - while (1) { - while (i < count && !get_user(ch, buf) && - (ch == DTLK_CLEAR || dtlk_writeable())) { - dtlk_write_tts(ch); - buf++; - i++; - if (i % 5 == 0) - /* We yield our time until scheduled - again.
