If it returns a null pointer, then the drive - * can't do DMA. Then call wdd_dmainit() to initialize the controller - * and drive. wdd_dmainit should leave PIO modes operational, though - * perhaps with suboptimal performance. - * - * Check the transfer by calling wdd_dmaverify(). The cookie is what - * you got before; vaddr is the virtual address of the buffer to be - * written; len is the length of the buffer; and direction is either - * B_READ or B_WRITE. This function verifies that the DMA hardware is - * capable of handling the request you've made. - * - * Setup the transfer by calling wdd_dmaprep(). This takes the same - * paramaters as wdd_dmaverify(). - * - * Send a read/write DMA command to the drive. - * - * Call wdd_dmastart(). - * - * Wait for an interrupt. Multi-sector transfers will only interrupt - * at the end of the transfer. - * - * Call wdd_dmadone(). It will return the status as defined by the - * WDDS_* constants below. - */ -struct wddma { - void *(*wdd_candma) /* returns a cookie if PCI */ - (int iobase_wd, int ctlr, int unit); - int (*wdd_dmaverify) /* verify that request is DMA-able */ - (void *cookie, char *vaddr, u_long len, int direction); - int (*wdd_dmaprep) /* prepare DMA hardware */ - (void *cookie, char *vaddr, u_long len, int direction); - void (*wdd_dmastart) /* begin DMA transfer */ - (void *cookie); - int (*wdd_dmadone) /* DMA transfer completed */ - (void *cookie); - int (*wdd_dmastatus) /* return status of DMA */ - (void *cookie); - int (*wdd_dmainit) /* initialize controller and drive */ - (void *cookie, - struct wdparams *wp, - int(wdcmd)(int mode, void *wdinfo), - void *wdinfo); - int (*wdd_iobase) /* returns iobase address */ - (void *cookie); - int (*wdd_altiobase) /* returns altiobase address */ - (void *cookie); -}; - -/* logical status bits returned by wdd_dmastatus */ -#define WDDS_ACTIVE 0x0001 -#define WDDS_ERROR 0x0002 -#define WDDS_INTERRUPT 0x0004 - -#define WDDS_BITS "\20\4interrupt\2error\1active" - -/* defines for ATA timing modes */ -#define WDDMA_GRPMASK 0xf8 -#define WDDMA_MODEMASK 0x07 -/* flow-controlled PIO modes */ -#define WDDMA_PIO 0x10 -#define WDDMA_PIO3 0x10 -#define WDDMA_PIO4 0x11 -/* multi-word DMA timing modes */ -#define WDDMA_MDMA 0x20 -#define WDDMA_MDMA0 0x20 -#define WDDMA_MDMA1 0x21 -#define WDDMA_MDMA2 0x22 - -/* Ultra DMA timing modes */ -#define WDDMA_UDMA 0x40 -#define WDDMA_UDMA0 0x40 -#define WDDMA_UDMA1 0x41 -#define WDDMA_UDMA2 0x42 - -#define Q_CMD640B 0x00000001 /* CMD640B quirk: serialize IDE channels */ -void wdc_pci(int quirks); - -extern struct wddma wddma[]; - -void wdintr(void *unit); - -#endif /* _KERNEL */ diff --git a/sys/pc98/pc98/wormio.h b/sys/pc98/pc98/wormio.h deleted file mode 100644 index 4d95d348c14f..000000000000 --- a/sys/pc98/pc98/wormio.h +++ /dev/null @@ -1,117 +0,0 @@ -/* Shared between kernel & process */ -/* $FreeBSD$ */ - -#ifndef _SYS_WORMIO_H_ -#define _SYS_WORMIO_H_ - -#include - -/***************************************************************\ -* Ioctls for the WORM drive * -\***************************************************************/ - - -/* - * Prepare disk-wide parameters. - */ - -struct wormio_prepare_disk -{ - int dummy; /* use dummy writes, laser turned off */ - int speed; /* drive speed selection */ -}; - -#define WORMIOCPREPDISK _IOW('W', 20, struct wormio_prepare_disk) - -/* - * Prepare track-specific parameters. - */ - -struct wormio_prepare_track -{ - int audio; /* audio track (data track if 0) */ - int preemp; /* audio with preemphasis */ -#define BLOCK_RAW 0 /* 2352 bytes, raw data */ -#define BLOCK_RAWPQ 1 /* 2368 bytes, raw data with P and Q subchannels */ -#define BLOCK_RAWPW 2 /* 2448 bytes, raw data with P-W subchannel appended */ -#define BLOCK_MODE_1 8 /* 2048 bytes, mode 1 (ISO/IEC 10149) */ -#define BLOCK_MODE_2 9 /* 2336 bytes, mode 2 (ISO/IEC 10149) */ -#define BLOCK_MODE_2_FORM_1 10 /* 2048 bytes, CD-ROM XA form 1 */ -#define BLOCK_MODE_2_FORM_1b 11 /* 2056 bytes, CD-ROM XA form 1 */ -#define BLOCK_MODE_2_FORM_2 12 /* 2324 bytes, CD-ROM XA form 2 */ -#define BLOCK_MODE_2_FORM_2b 13 /* 2332 bytes, CD-ROM XA form 2 */ - int track_type; /* defines the number of bytes in a block */ -#define COPY_INHIBIT 0 /* no copy allowed */ -#define COPY_PERMITTED 1 /* track can be copied */ -#define COPY_SCMS 2 /* alternate copy */ - int copy_bits; /* define the possibilities for copying */ - int track_number; - char ISRC_country[2]; /* country code (2 chars) */ - char ISRC_owner[3]; /* owner code (3 chars) */ - int ISRC_year; /* year of recording */ - char ISRC_serial[5]; /* serial number */ -}; -#define WORMIOCPREPTRACK _IOW('W', 21, struct wormio_prepare_track) - - -/* - * Fixation: write leadins and leadouts.
