From 86297c41a26f18d924e64fc93321c59cbc4c48dd Mon Sep 17 00:00:00 2001 From: Thomas Bushnell Date: Mon, 26 Apr 1999 05:58:44 +0000 Subject: 1998-11-30 OKUJI Yoshinori Clean up linux emulation code to make it architecture-independent as much as possible. * linux: Renamed from linuxdev. * Makefile.in (objfiles): Add linux.o instead of linuxdev.o. (MAKE): New variable. Used for the linux.o target. * configure.in: Add AC_CHECK_TOOL(MAKE, make). * i386/i386/spl.h: Include , for compatibility with OSF Mach 3.0. Suggested by Elgin Lee . * linux/src: Renamed from linux/linux. * linux/dev: Renamed from linux/mach. * linux/Drivers.in (AC_INIT): Use dev/include/linux/autoconf.h, instead of mach/include/linux/autoconf.h. * Makefile.in (all): Target ../linux.o instead of ../linuxdev.o. * linux/dev/drivers/block/genhd.c: Include instead of . * linux/dev/drivers/net/auto_irq.c: Remove unneeded header files, and . * linux/dev/init/main.c: Many i386-dependent codes moved to ... * linux/dev/arch/i386/irq.c: ... here. * linux/dev/arch/i386/setup.c: New file. * linux/dev/arch/i386/linux_emul.h: Likewise. * linux/dev/arch/i386/glue/timer.c: Merged into sched.c. * linux/dev/arch/i386/glue/sched.c: Include instead of , and moved to ... * linux/dev/kernel/sched.c: ... here. * linux/dev/arch/i386/glue/block.c: Include and , instead of i386-dependent header files, and moved to ... * linux/dev/glue/blocl.c: ... here. * linux/dev/arch/i386/glue/net.c: Include and , instead of i386-dependent header files, and moved to ... * linux/dev/glue/net.c: ... here. * linux/dev/arch/i386/glue/misc.c: Remove `x86' and moved to ... * linux/dev/glue/misc.c: ... here. * linux/dev/arch/i386/glue/kmem.c: Moved to ... * linux/dev/glue/kmem.c: ... here. --- linux/src/drivers/scsi/eata_pio_proc.c | 135 +++++++++++++++++++++++++++++++++ 1 file changed, 135 insertions(+) create mode 100644 linux/src/drivers/scsi/eata_pio_proc.c (limited to 'linux/src/drivers/scsi/eata_pio_proc.c') diff --git a/linux/src/drivers/scsi/eata_pio_proc.c b/linux/src/drivers/scsi/eata_pio_proc.c new file mode 100644 index 0000000..54783f2 --- /dev/null +++ b/linux/src/drivers/scsi/eata_pio_proc.c @@ -0,0 +1,135 @@ + +/* + * eata_set_info + * buffer : pointer to the data that has been written to the hostfile + * length : number of bytes written to the hostfile + * HBA_ptr: pointer to the Scsi_Host struct + */ +int eata_pio_set_info(char *buffer, int length, struct Scsi_Host *HBA_ptr) +{ + DBG(DBG_PROC_WRITE, printk("%s\n", buffer)); + return(-ENOSYS); /* Currently this is a no-op */ +} + +/* + * eata_proc_info + * inout : decides on the direction of the dataflow and the meaning of the + * variables + * buffer: If inout==FALSE data is being written to it else read from it + * *start: If inout==FALSE start of the valid data in the buffer + * offset: If inout==FALSE offset from the beginning of the imaginary file + * from which we start writing into the buffer + * length: If inout==FALSE max number of bytes to be written into the buffer + * else number of bytes in the buffer + */ +int eata_pio_proc_info(char *buffer, char **start, off_t offset, int length, + int hostno, int inout) +{ + + Scsi_Device *scd; + struct Scsi_Host *HBA_ptr; + static u8 buff[512]; + int i; + int size, len = 0; + off_t begin = 0; + off_t pos = 0; + + HBA_ptr = first_HBA; + for (i = 1; i <= registered_HBAs; i++) { + if (HBA_ptr->host_no == hostno) + break; + HBA_ptr = SD(HBA_ptr)->next; + } + + if(inout == TRUE) /* Has data been written to the file ?
