2006-04-13[SCSI] Simplify error handling a bitMatthew Wilcox1-42/+8
- to_do was never set to SYM_EH_DO_COMPLETE, so remove that code - move the spinlocks inside the common error handler code path Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-04-13[SCSI] Use pcibios_resource_to_bus()Matthew Wilcox1-42/+13
We had our own code (pci_get_base_address()) to get the bus address of a BAR. We can get this using pcibios_resource_to_bus() instead. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-04-13[SCSI] Change Kconfig option from IOMAPPED to MMIOMatthew Wilcox2-13/+18
Most of the Kconfig options for switching between IO Port and MMIO operations use the opposite sense from sym2. Really, this option should be set at a chipset level rather than per-driver. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

2006-02-28[SCSI] Fix uninitialised width and speed in sym2Matthew Wilcox1-0/+2
sym2 boards without NVRAM currently negotiate narrow due to this missed initialisation Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-02-27[SCSI] Add spi_populate_*_msg functionsMatthew Wilcox1-41/+12
Introduce new helpers: - spi_populate_width_msg() - spi_populate_sync_msg() - spi_populate_ppr_msg() and use them in drivers which already enable the SPI transport. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-02-12[SCSI] sym2: Mask off opcode from RBCMatthew Wilcox1-1/+1
pm->sg.size is set from the Residual Byte Count register. However, the upper byte of the RBC is the opcode of the instruction that was executing, so we need to mask it off. This fixes some spurious rejects of IGNORE WIDE RESIDUE messages. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-15[SCSI] Rename scsi_print_msg to spi_print_msgMatthew Wilcox1-2/+2
Rename scsi_print_msg to spi_print_msg and move its prototype from scsi_dbg.h to scsi_transport_spi.h Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-15Merge by hand (conflicts in scsi_lib.c)James Bottomley1-2/+2
This merge is pretty extensive. The conflict is over the new req->retries parameter, so I had to change the prototype to scsi_setup_blk_pc_cmnd() and the usage in sd, sr and st. Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-13[SCSI] sym2: Version 2.2.2Matthew Wilcox1-1/+1
Update version number to 2.2.2 Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-13[SCSI] sym2: Report disabled devices and LUNs more attractivelyMatthew Wilcox2-33/+11
Rather than print a list of targets at driver init time, print each disabled target as we attempt to scan it. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-13[SCSI] sym2: Allow NVRAM settings to limit speed and widthMatthew Wilcox5-18/+26
The NVRAM for both Tekram and Symbios boards allows the user to set the speed and width for individual targets. I took that code out in March 2004 when we introduced Domain Validation, but it seems there's still a legitimate need for it in some configurations.

2005-12-13[SCSI] sym2: Use scsi_print_msgMatthew Wilcox1-24/+5
sym_show_msg was almost a duplicate of scsi_print_msg, except not as featureful. So use the common code instead. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-13[SCSI] sym2: Use DMA_40BIT_MASK constantMatthew Wilcox1-1/+1
Now that this constant has been added to dma-mapping.h, we don't need our own definition Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-13[SCSI] sym2: Remove code to handle DMA_BIDIRECTION requestsMatthew Wilcox8-204/+40
The upper layer doesn't send these down since 2.4.x (or 2.6 in practice), so no need to handle it. Inline sym_setup_data_pointers into its only caller so we can fail gracefully in the case we'd get one neverless.

2005-12-13[SCSI] sym2: Manage sym_lcb properlyMatthew Wilcox3-121/+38
Allocate the lcb in slave_alloc and free it in slave_destroy. This allows us to remove all the code that checks to see if it's already been allocated. From: Christoph Hellwig <hch@lst.de> Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-13[SCSI] sym2: Remove last vestiges of sym_sniff_inquiryMatthew Wilcox2-10/+0
The SYM_OPT_SNIFF_INQUIRY define is never set any more, and the sym_sniff_inquiry() function doesn't exist From: Christoph Hellwig <hch@lst.de> Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-13[SCSI] sym2: Remove FreeBSD ifdefsMatthew Wilcox2-16/+0
Remove FreeBSD ifdefs from sym2 driver Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-13[SCSI] Negotiate correctly with async-only devicesMatthew Wilcox1-2/+2
When we got a device only capable of async, we would zero out goal->period which would cause us to try PPR negotiations. Leave goal->period alone, and check goal->offset before doing PPR. Kudos to Daniel Forsgren for figuring this out. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-01[SCSI] sym2: Disable IU and QAS negotiationMatthew Wilcox1-1/+4
Enabling these features causes problems with some drives, so disable them until they're debugged Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-11-07[PATCH] fix remaining missing includesTim Schmielau1-0/+1
Fix more include file problems that surfaced since I submitted the previous fix-missing-includes.patch. This should now allow not to include sched.h from module.h, which is done by a followup patch.

2005-10-30[PATCH] fix missing includesTim Schmielau2-0/+5
I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.

2005-05-26[SCSI] sym2 version 2.2.1Matthew Wilcox6-137/+106
sym2 version 2.2.1: - Fix MMIO BAR detection (Thanks to Bob Picco) - Fix odd-sized transfers with a wide bus (Thanks to Larry Stephens) - Write posting fixes (Thanks to Thibaut Varene) - Change one of the GFP_KERNEL allocations back into a GFP_ATOMIC - Make CCB_BA() return a script-endian address - Move range checks and disabling of devices from the queuecommand path to slave_alloc() - Remove a warning in sym_setup_cdb() - Keep a pointer to the scsi_target instead of the scsi_dev in the tcb - Remove a check for the upper layers passing an oversized cmd - Replace CAM_REQ_ constants with the Linux DID_ constants - Replace CAM_DIR_ constants with the Linux DMA_ constants - Inline sym_read_parisc_pdc() on non-parisc systems Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-05-06[SCSI] correct the sym2 period setting routinesJames Bottomley1-2/+3
There's a slight bug in the routines in that if the period requires dt, then the routine will unconditionally set it. DT may only be set if Wide is also set, so this turns back on the wide bit. For domain validation to work correctly, we need to observe the wide bit absolutely. Acked by: Matthew Wilcox <willy@debian.org> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-04-18[PATCH] scsi: remove meaningless scsi_cmnd->serial_number_at_timeout field1-6/+0
scsi_cmnd->serial_number_at_timeout doesn't serve any purpose anymore. All serial_number == serial_number_at_timeout tests are always true in abort callbacks. Kill the field. Also, as ->pid always equals ->serial_number and ->serial_number doesn't have any special meaning anymore, update comments above ->serial_number accordingly. Once we remove all uses of this field from all lldd's, this field should go. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-04-16Linux-2.6.12-rc2Linus Torvalds15-0/+16781
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
