2007-10-23[SCSI] sym53c8xx: Remove sym_xpt_async_sent_bdrMatthew Wilcox
This function just printed a message to the user; move the print to its only caller, and turn it into an starget_printk. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-23[SCSI] sym53c8xx: Remove pci_dev pointer from sym_shcbMatthew Wilcox
This structure is accessed by the device; the fewer Linux things in it, the better. Using the pci_dev pointer from the hostdata requires a lot of changes: - Pass Scsi_Host to a lot of routines which currently take a sym_hcb. - Set the Scsi_Host as the pci drvdata (instead of the sym_hcb) Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-23[SCSI] sym53c8xx: Make interrupt handler capable of returning IRQ_NONEMatthew Wilcox
Make sym_interrupt return an irqreturn_t instead of void, and take a Scsi_Host instead of a sym_hcb. Pass the Scsi_Host to the interrupt handler instead of the sym_hcb. Rename the host_data to sym_data. Keep a pci_dev pointer in the sym_data. Rename the Scsi_Host from instance to shost.

2007-10-23[SCSI] sym53c8xx: Get rid of IRQ_FMT and IRQ_PRMMatthew Wilcox
These macros aren't needed any more. They used to be used for SPARC. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-23[SCSI] sym53c8xx: Use scmd_printk where appropriateMatthew Wilcox
If we have a scsi_cmnd, it gives the user more information than the sym_name, and maybe the target. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-23[SCSI] sym53c8xx: Simplify DAC DMA handlingMatthew Wilcox
By introducing the use_dac(), set_dac() and DMA_DAC_MASK macros, we can eliminate a lot of ifdefs from the code. We now rely on the compiler to optimise away a few things that we'd formerly relied on the preprocessor to do. This makes sym_setup_bus_dma_mask() small enough to inline into its only caller. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-23[SCSI] sym53c8xx: Remove tag_ctrl module parameterMatthew Wilcox
With sysfs making these options tunable at runtime, there's no justification for keeping this horrendously complex specification string around. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-23[SCSI] sym53c8xx: Remove io_ws, mmio_ws and ram_ws elementsMatthew Wilcox

2007-10-23[SCSI] sym53c8xx: PCI Error Recovery supportLinas Vepstas
This patch adds the PCI error recovery callbacks to the Symbios SCSI device driver. It includes support for First Failure Data Capture. Signed-off-by: Linas Vepstas <linas@austin.ibm.com> Assorted changes to initial patches, including returning IRQ_NONE from the interrupt handler if the device is offline and re-using the eh_done completion in the scsi error handler. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-23[SCSI] sym53c8xx: Stop overriding scsi_doneMatthew Wilcox
Instead of telling the reset routine that the command completed from sym_eh_done, do it from sym_xpt_done. The 'to_do' element of the ucmd is redundant -- it serves only to tell whether eh_done is valid or not, and we can tell this by checking to see if it's NULL. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-23[SCSI] sym53c8xx: Don't disable interrupts in the interrupt handlerMatthew Wilcox
Interrupts can't be re-entered, so it's sufficient to call spin_lock, not spin_lock_irqsave(). Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-23[SCSI] sym53c8xx: Remove unnecessary check in queuecommandMatthew Wilcox
The midlayer won't scan the host ID, so we don't need to check. This is the only caller of sym_xpt_done2, so remove that too. Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2007-10-23[SCSI] sym53c8xx: Remove data_mapping and data_mappedMatthew Wilcox
Before all commands used sg, data_mapping and data_mapped were used to distinguish whether the command had used map_single or map_sg. Now all commands are sg, so we can delete data_mapping, data_mapped and the wrapper functions __unmap_scsi_data, __map_scsi_sg_data, unmap_scsi_data and map_scsi_sg_data.

2007-10-23[SCSI] qla1280: eliminate wasted space in request and response ringJohannes Dickgreber
i think there is wasted space in allocated pages for request and response rings. The allocations are made with REQUEST_ENTRY_CNT + 1 and RESPONSE_ENTRY_CNT + 1, but they are set with 256 and 16. So we got more pages, which we dont use very much so eliminate them.

2007-10-21[SCSI] aic7xxx: Add suspend/resume supportHannes Reinecke
The aic7xxx driver already contains fragments for suspend/resume support. So we only need to update them to the current interface and have full PCI suspend/resume.

2007-10-17[SCSI] hptiop: avoid buffer overflow when returning sense dataHighPoint Linux Team

2007-10-17[SCSI] make supported_mode default to initiator.James Bottomley

2007-10-17[SCSI] include linux/scatterlist.h in scsi_eh.hJames Bottomley
Spotted by Paul Jackson <pj@sgi.com> The error handler rework moved the scatterlist into a globally exposed structure in scsi_eh.h; unfortunately, the scatterlist include needs to move from scsi_error.c to scsi_eh.h to allow this to compile universally.

2007-10-17[SCSI] fc4: remove this and all associated driversMatthew Wilcox
This code has been slowly rotting for about eight years. It's currently impeding a few SCSI cleanups, and nobody seems to have hardware to test it any more. I talked to Dave Miller about it, and he agrees we can delete it. If anyone wants a software FC stack in future, they can retrieve this driver from git.

2007-10-17Revert "[SCSI] Remove full sg table memset()"Jens Axboe
A bit too eager - we definitely need to clear the sg table initially, so that we don't accidentally have ->page & 0x01 true and think that is a chain pointer. This reverts commit f5c0dde4c66421a3a2d7d6fa604a712c9b0744e5.
