[SCSI] hptiop: HighPoint RocketRAID 3xxx controller driver
HighPoint RocketRAID 3220/3320 series 8 channel PCI-X SATA RAID Host Adapters. 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 <linux@highpoint-tech.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

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. For requests
|
||||
allocated in IOP memory, write the offset to inbound queue port. For
|
||||
requests allocated in host memory, write (0x80000000|(bus_addr>>5))
|
||||
to the inbound queue port.
|
||||
|
||||
- The IOP process the request. When the request is completed, it
|
||||
will be put into outbound queue. An outbound interrupt will be
|
||||
generated.
|
||||
|
||||
For requests allocated in IOP memory, the request offset is posted to
|
||||
outbound queue.
|
||||
|
||||
For requests allocated in host memory, (0x80000000|(bus_addr>>5))
|
||||
is posted to the outbound queue. If IOP_REQUEST_FLAG_OUTPUT_CONTEXT
|
||||
flag is set in the request, the low 32-bit context value will be
|
||||
posted instead.
|
||||
|
||||
- The host read the outbound queue and complete the request.
|
||||
|
||||
For requests allocated in IOP memory, the host driver free the request
|
||||
by writing it to the outbound queue.
|
||||
|
||||
Non-queued requests (reset/flush etc) can be sent via inbound message
|
||||
register 0. An outbound message with the same value indicates the completion
|
||||
of an inbound message.
|
||||
|
||||
|
||||
User-level Interface
|
||||
---------------------
|
||||
|
||||
The driver exposes following sysfs attributes:
|
||||
|
||||
NAME R/W Description
|
||||
driver-version R driver version string
|
||||
firmware-version R firmware version string
|
||||
|
||||
The driver registers char device "hptiop" to communicate with HighPoint RAID
|
||||
management software. Its ioctl routine acts as a general binary interface
|
||||
between the IOP firmware and HighPoint RAID management software. New management
|
||||
functions can be implemented in application/firmware without modification
|
||||
in driver code.
|
||||
