2009-05-20[SCSI] sym53c8xx_2: slave_alloc/destroy safety (2.6.27.5)Aaro Koskinen
Make the sym53c8xx_2 driver slave_alloc/destroy less unsafe. References to the destroyed LCB are cleared from the target structure (instead of leaving a dangling pointer), and when the last LCB for the target is destroyed the reference to the upper layer target data is cleared. The host lock is used to prevent a race with the interrupt handler. Also user commands are prevented for targets with all LCBs destroyed.

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.

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: 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.

Undef SYM_OPT_HANDLE_DEVICE_QUEUEING. Call sym_put_start_queue instead of sym_start_next_ccbs.

2005-12-13[SCSI] sym2: Allow NVRAM settings to limit speed and widthMatthew Wilcox
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: Remove code to handle DMA_BIDIRECTION requestsMatthew Wilcox
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.

2005-10-30[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!
