driver. * This includes the PCI/EISA/ISA SCSI Disk Array Controllers and the * PCI Fibre Channel Disk Array Controllers. See gdth.h for a complete * list of all controller types. * * If you have one or more GDT3000/3020 EISA controllers with * controller BIOS disabled, you have to set the IRQ values with the * command line option "gdth=irq1,irq2,...", where the irq1,irq2,... are * the IRQ values for the EISA controllers. * * After the optional list of IRQ values, other possible * command line options are: * disable:Y disable driver * disable:N enable driver * reserve_mode:0 reserve no drives for the raw service * reserve_mode:1 reserve all not init., removable drives * reserve_mode:2 reserve all not init. drives * reserve_list:h,b,t,l,h,b,t,l,... reserve particular drive(s) with * h- controller no., b- channel no., * t- target ID, l- LUN * reverse_scan:Y reverse scan order for PCI controllers * reverse_scan:N scan PCI controllers like BIOS * max_ids:x x - target ID count per channel (1..MAXID) * rescan:Y rescan all channels/IDs * rescan:N use all devices found until now * virt_ctr:Y map every channel to a virtual controller * virt_ctr:N use multi channel support * hdr_channel:x x - number of virtual bus for host drives * shared_access:Y disable driver reserve/release protocol to * access a shared resource from several nodes, * appropiate controller firmware required * shared_access:N enable driver reserve/release protocol * * The default values are: "gdth=disable:N,reserve_mode:1,reverse_scan:N, * max_ids:127,rescan:N,virt_ctr:N,hdr_channel:0, * shared_access:Y". * Here is another example: "gdth=reserve_list:0,1,2,0,0,1,3,0,rescan:Y". * * When loading the gdth driver as a module, the same options are available. * You can set the IRQs with "IRQ=...". However, the syntax to specify the * options changes slightly. You must replace all ',' between options * with ' ' and all ':' with '=' and you must use * '1' in place of 'Y' and '0' in place of 'N'. * * Default: "modprobe gdth disable=0 reserve_mode=1 reverse_scan=0 * max_ids=127 rescan=0 virt_ctr=0 hdr_channel=0 shared_access=0" * The other example: "modprobe gdth reserve_list=0,1,2,0,0,1,3,0 rescan=1". */ /* The meaning of the Scsi_Pointer members in this driver is as follows: * ptr: Chaining * this_residual: Command priority * buffer: Unused * buffers_residual: Timeout value * Status: Command status (gdth_do_cmd()) * Message: Additional info (gdth_do_cmd()) * have_data_in: Flag for gdth_wait_completion() * sent_command: Opcode special command * phase: Service/parameter/return code special command */ #include <linux/module.h> #include <linux/version.h> #include <linux/kernel.h> #include <linux/types.h> #include <linux/pci.h> #include <linux/string.h> #include <linux/ctype.h> #include <linux/ioport.h> #include <linux/delay.h> #include <linux/sched.h> #include <linux/in.h> #include <linux/proc_fs.h> #include <linux/time.h> #include <linux/timer.h> #ifdef GDTH_RTC #include <linux/mc146818rtc.h> #endif #if LINUX_VERSION_CODE >= 0x020100 #include <linux/reboot.h> #else #include <linux/bios32.h> #endif #include <asm/dma.h> #include <asm/system.h> #include <asm/io.h> #if LINUX_VERSION_CODE >= 0x020322 #include <linux/spinlock.h> #elif LINUX_VERSION_CODE >= 0x02015F #include <asm/spinlock.h> #endif #if LINUX_VERSION_CODE >= 0x010300 #include <linux/blk.h> #else #include "../block/blk.h" #endif #include "scsi.h" #include "hosts.h" #include "sd.h" #include "gdth.h" static void gdth_delay(int milliseconds);
