2009-03-12[SCSI] sym53c8xx: don't flood syslog with negotiation messagesTony Battersby
sym53c8xx prints a negotiation message after every check condition. This can add up to a lot of messages for removable-medium devices (CD-ROM, tape drives, etc.) that are being polled, since they return check condition when no medium is present. This patch suppresses the negotiation message if it would be the same as the last one printed.

2009-03-12[SCSI] sym53c8xx: Keep transfer negotiations validAaro Koskinen
(The patch updated based on testing and comments from Tony Battersby.) Change the sym53c8xx_2 driver negotiation logic so that the driver will tolerate better device removals. Negotiation message(s) will be sent with every INQUIRY and REQUEST SENSE command, and whenever there is a change in goals or when the device reports check condition. The patch was made specifically to address the case where you hotswap the disk using remove-single-device/add-single-device commands through /proc/scsi/scsi. Without the patch the driver keeps using old transfer parameters even though the target is reset and reports check condition, so the data transfer of the very first INQUIRY will fail.

2008-07-26[SCSI] sym53c8xx: free luntbl in sym_hcb_freeMike Anderson
This patch frees the luntbl dma area in sym_hcb_free if allocated. Since the luntbl is part of a larger dma coherent area not freeing the luntbl kept a 64k dma coherent area previous allocated through dma_alloc_coherent allocated. This prevented a DLPAR remove IO operation from completing successfully.

2008-02-07[SCSI] sym53c8xx: fix resid calculationTony Battersby

2007-12-18[SCSI] sym53c8xx: fix "irq X: nobody cared" regressionTony Battersby
The patch described by the following excerpt from ChangeLog-2.6.24-rc1 eventually causes a "irq X: nobody cared" error after a while: commit 99c9e0a1d6cfe1ba1169a7a81435ee85bc00e4a1 Author: Matthew Wilcox <matthew@wil.cx> Date: Fri Oct 5 15:55:12 2007 -0400 [SCSI] sym53c8xx: Make interrupt handler capable of returning IRQ_NONE After this happens, the kernel disables the IRQ, causing the SCSI card to stop working until the next reboot. The problem is caused by the interrupt handler returning IRQ_NONE instead of IRQ_HANDLED after handling an interrupt-on-the-fly (INTF) condition. The following patch fixes the problem.

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: 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.

2006-02-12[SCSI] sym2: Mask off opcode from RBCMatthew Wilcox
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.

2005-12-13[SCSI] Negotiate correctly with async-only devicesMatthew Wilcox

2005-10-30[PATCH] fix missing includesTim Schmielau
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.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
