Fixes from original submission: Merge Andrew Morton's patches: - Provide locking for global list - Fix debug printks - uninline function with multiple callsites - coding style fixups - remove unneeded casts of void* - kfree(NULL) is legal - Don't "succeed" if register_chrdev() failed - otherwise we'll later unregister a not-registered chrdev. - Don't return from hptiop_do_ioctl() with the spinlock held. - uninline __hpt_do_ioctl() Update for Arjan van de Ven's comments: - put all asm/ includes after the linux/ ones - replace mdelay with msleep - add pci posting flush - do not set pci command reqister in map_pci_bar - do not try merging sg elements in hptiop_buildsgl() - remove unused outstandingcommands member from hba structure - remove unimplemented hptiop_abort() handler - remove typedef u32 hpt_id_t Other updates: - fix endianess Signed-off-by: HighPoint Linux Team Signed-off-by: James Bottomley --- Documentation/scsi/hptiop.txt | 92 +++ MAINTAINERS | 6 + drivers/scsi/Kconfig | 10 + drivers/scsi/Makefile | 1 + drivers/scsi/hptiop.c | 1501 +++++++++++++++++++++++++++++++++++++++++ drivers/scsi/hptiop.h | 465 +++++++++++++ 6 files changed, 2075 insertions(+) create mode 100644 Documentation/scsi/hptiop.txt create mode 100644 drivers/scsi/hptiop.c create mode 100644 drivers/scsi/hptiop.h (limited to 'Documentation') diff --git a/Documentation/scsi/hptiop.txt b/Documentation/scsi/hptiop.txt new file mode 100644 index 000000000000..d28a31247d4c --- /dev/null +++ b/Documentation/scsi/hptiop.txt @@ -0,0 +1,92 @@ +HIGHPOINT ROCKETRAID 3xxx RAID DRIVER (hptiop) + +Controller Register Map +------------------------- + +The controller IOP is accessed via PCI BAR0. + + BAR0 offset Register + 0x10 Inbound Message Register 0 + 0x14 Inbound Message Register 1 + 0x18 Outbound Message Register 0 + 0x1C Outbound Message Register 1 + 0x20 Inbound Doorbell Register + 0x24 Inbound Interrupt Status Register + 0x28 Inbound Interrupt Mask Register + 0x30 Outbound Interrupt Status Register + 0x34 Outbound Interrupt Mask Register + 0x40 Inbound Queue Port + 0x44 Outbound Queue Port + + +I/O Request Workflow +---------------------- + +All queued requests are handled via inbound/outbound queue port. +A request packet can be allocated in either IOP or host memory. + +To send a request to the controller: + + - Get a free request packet by reading the inbound queue port or + allocate a free request in host DMA coherent memory. + + The value returned from the inbound queue port is an offset + relative to the IOP BAR0. + + Requests allocated in host memory must be aligned on 32-bytes boundary. + + - Fill the packet. + + - Post the packet to IOP by writing it to inbound queue.

(some HW behaves differently than others in this area.) - * Changed Makefile to rely on "make dep" instead of explicit dependencies - * ifdef'ed out fibre channel analyzer triggering debug code - * fixed a jiffies wrapping issue - -Ver 2.0.4 Aug 01, 2001 - * Incorporated fix for target device reset from Steeleye - * Fixed passthrough ioctl so it doesn't hang. - * Fixed hang in launch_FCworker_thread() that occurred on some machines. - * Avoid problem when number of volumes in a single cabinet > 8 - -Ver 2.0.2 July 23, 2001 - Changed the semiphore changes so the driver would compile in 2.4.7. - This version is for 2.4.7 and beyond. - -Ver 2.0.1 May 7, 2001 - Merged version 1.3.6 fixes into version 2.0.0. - -Ver 2.0.0 May 7, 2001 - Fixed problem so spinlock is being initialized to UNLOCKED. - Fixed updated driver so it compiles in the 2.4 tree. - - Ver 1.3.6 Feb 27, 2001 - Added Target_Device_Reset function for SCSI error handling - Fixed problem with not reseting addressing mode after implicit logout - - -Ver 1.3.4 Sep 7, 2000 - Added Modinfo information - Fixed problem with statically linking the driver - -Ver 1.3.3, Aug 23, 2000 - Fixed device/function number in ioctl - -Ver 1.3.2, July 27, 2000 - Add include for Alpha compile on 2.2.14 kernel (cpq*i2c.c) - Change logic for different FCP-RSP sense_buffer location for HSG80 target - And search for Agilent Tachyon XL2 HBAs (not finished! - in test) - -Tested with -(storage): - Compaq RA-4x000, RAID firmware ver 2.40 - 2.54 - Seagate FC drives model ST39102FC, rev 0006 - Hitachi DK31CJ-72FC rev J8A8 - IBM DDYF-T18350R rev F60K - Compaq FC-SCSI bridge w/ DLT 35/70 Gb DLT (tape) -(servers): - Compaq PL-1850R - Compaq PL-6500 Xeon (400MHz) - Compaq PL-8500 (500MHz, 66MHz, 64bit PCI) - Compaq Alpha DS20 (RH 6.1) -(hubs): - Vixel Rapport 1000 (7-port "dumb") - Gadzoox Gibralter (12-port "dumb") - Gadzoox Capellix 2000, 3000 -(switches): - Brocade 2010, 2400, 2800, rev 2.0.3a (& later) - Gadzoox 3210 (Fabric blade beta) - Vixel 7100 (Fabric beta firmare - known hot plug issues) -using "qa_test" (esp. io_test script) suite modified from Unix tests. - -Installation: -make menuconfig - (select SCSI low-level, Compaq FC HBA) -make modules -make modules_install - -e.g. insmod -f cpqfc - -Due to Fabric/switch delays, driver requires 4 seconds -to initialize.

Some SCSI drives with error conditions will not handle the 7 second timeout -in this software driver, leading to infinite retries on timed out SCSI commands. -The 7 secs balances the need to quickly recover from lost frames (esp. on sequence -initiatives) and time needed by older/slower/error-state drives in responding. -This can be easily changed in "Exchanges[].timeOut". - -4. Due to the nature of FC soft addressing, there is no assurance that the -same LUNs (drives) will have the same path (e.g. /dev/sdb1) from one boot to -next.

Compaq RA4x00 firmware version 2.54 and later supports SSP (Selective -Storage Presentation), which maps LUNs to a WWN. If RA4x00 firmware prior -2.54 (e.g. older controller) is used, or the FC HBA is replaced (another WWN -is used), logical volumes on the RA4x00 will no longer be visible. - - -Send questions/comments to: -Amy Vanzant-Hodge (fibrechannel@compaq.com) - -- cgit v1.2.3-59-g8ed1b From 75c3628db75c573870379094a5f90f690ee99b76 Mon Sep 17 00:00:00 2001 From: Mark Haverkamp Date: Thu, 8 Jun 2006 13:55:42 -0700 Subject: [SCSI] aacraid: Update supported product information Received From Mark Salyzyn Some of the cards product names changed.
